## CHAPTER 1
NUCLEAR, BIOLOGICAL, AND CHEMICAL WARFARE ASPECT OF THE MEDICAL THREAT

#### 1-1. General

a. After World War II, the Soviet Union represented the principal threat to the national security interests of the US. During this period, the military capability of the Soviet Armed Forces grew enormously. Starting in the later years of the 1980s, the international security environment has undergone rapid, fundamental, and revolutionary changes. With the collapse of Soviet communism, the Soviet Union disintegrated as a viable economic and political system. The Warsaw Pact dissolved as a political and military entity. The central Soviet government was replaced by the Commonwealth of Independent States (CIS), dominated by the Russian Republic. The cohesion of Soviet strategic military capability has been fractured by—

- The dissolution of central Soviet control.
- The formation of the CIS.
- The unpredictability associated with uncertain loyalties and low morale.

The ultimate outcome of these events in terms of US national security interests is unclear. The military capabilities of CIS like Russia, Ukraine, Kazakstan, and Belarus remain formidable. The capabilities include strategic nuclear and impressive conventional, biological, and chemical warfighting capabilities.

b. From a global perspective, the economic power and influence of developing and newly industrialized nations continue to grow. Centers of power (global or regional) cannot be measured solely in military terms. Nation states pursuing their own political, ideological, and economic interests may become engaged in direct or indirect competition and conflict with the US. More nations have acquired significant numbers of modern, lethal, combat weapon systems; developed very capable armed forces; and become more assertive in international affairs. In the absence of a single, credible, coercive threat, old rivalries and long repressed territorial ambitions will resurface, causing increased tensions in many regions. Political, economic, and social instability and religious, cultural, and economic competition will continue to erode the influence of the US over the rest of the world. This erosion will also reduce the US influence of traditional regional powers over their neighbors. This environment will encourage the continued development, or acquisition, of modern armed forces and equipment by less influential nations; thus raising the potential for the use of NBC/RDD weapons during internal conflict and armed confrontations in developing regions of the world.

c. A third dimension to the threat is terrorist, rogue groups, and belligerents employing a number of chemical and biological agents and the possible use of TIM to injure or kill US personnel. The actions may be isolated or may be imposed by groups of individuals. Most will have the financial backing of nations, large organizations, or groups that have the desire to cause harm and create public distrust in our government.

#### 1-2. Medical Threat

Medical threat is the composite of all ongoing or potential enemy actions and environmental conditions that [1-2] will reduce combat effectiveness through wounding, injuring, causing disease, and/or degrading performance. Soldiers are the targets of these threats. Weapons or environmental conditions that will generate wounded, injured, and sick soldiers, beyond the capability of the HSS system to provide timely medical care from available resources, are considered major medical threats. Weapons or environmental conditions that produce qualitatively different wound or disease processes are also major medical threats. Added to the combat operational and disease and nonbattle injury (DNBI) medical threats are adversary use of the following types of weapons, agents, and devices:

- Biological warfare agents.
- Chemical warfare agents.
- Nuclear weapons.
- Toxic industrial materials.
- Radiological dispersal devices.
- Directed-energy devices/weapons.
- Chemical, biological, radiological, nuclear, and high-yield explosives.

#### 1-3. Nuclear, Biological, Chemical, and Radiological Dispersal Device Threats—The Health Service Perspective

a. Nuclear Weapons and Radiological Dispersal Device Threats. Since the breakup of the Soviet Union, the number of countries with known nuclear capable military forces has almost doubled. Available information suggests that a number of countries in the Middle East, Asia, and Africa have or may have nuclear weapons capability within the next decade. Table 1-1 lists those countries known to have, suspected of possessing, or seeking, nuclear weapons. Planners can expect, as a minimum, 10 to 20 percent casualties within a division-sized force that has experienced a nuclear strike. In addition to the casualties, a nuclear weapon detonation can generate an electromagnetic pulse (EMP) that will cause catastrophic failures of electronic equipment components. Radiological dispersal devices, comprised of an explosive device with radioactive material, can be detonated without the need for the components of a nuclear weapon. The RDD can disperse radioactive material over an area of the battlefield causing effects from nuisance levels of radioactive material to life-threatening levels without the thermal and, in most cases, the blast effects of a nuclear detonation. For nuclear weapons effects see Appendix A.

b. Biological Warfare.

(1) Biological warfare (BW) is defined by the US intelligence community as the intentional use of disease-causing organisms (pathogens), toxins, or other agents of biological origin (ABO) to incapacitate, injure, or kill humans and animals; to destroy crops; to weaken resistance to attack; and to reduce the will to fight. Historically, BW has primarily involved the use of pathogens in assassinations or as sabotage agents in food and water supplies to spread contagious disease among target populations.

(2) For purposes of medical threat risk assessment, we are interested only in those BW agents that incapacitate, injure, or kill humans or animals.

(3) Known or suspect BW agents and ABOs can generally be categorized as naturally occurring, unmodified infectious agents (pathogens); toxins, venoms, and their biologically active fractions; modified infectious agents; and bioregulators. See Table 1-2 for examples of known or suspected BW threat agents. Also, Table 1-3 presents possible developmental and future BW agents.

(4) Many governments recognize the industrial and economic potential of advanced biotechnology and bioengineering. The same knowledge, skills, and methodologies can be applied to the production of second and third generation BW agents. Naturally occurring infectious organisms can be made more virulent and antibiotic resistant and manipulated to render protective vaccines ineffective. These developments complicate the ability to detect and identify BW agents and to operate in areas contaminated by the BW agents. For biological agent characteristics and effects see Appendix A. The first indication that a BW agent release/attack has occurred may be patients presenting at a medical treatment facility with symptoms not fitting the mold for endemic diseases in the area of operations (AO). See Appendix B for sampling requirements, sampling procedures, packaging and shipping, and chain of custody requirements.

c. Chemical Warfare.

(1) Since World War I, most western political and military leaders have publicly held chemical warfare (CW) in disrepute. However, evidence accumulated over the last 50 years does not support the position that public condemnation equates to limiting development or use of offensive CW agents. The reported use of chemical agents and biological toxins in Southeast Asia by Vietnamese forces; the confirmed use of CW agents by Egypt against Yemen; and later by Iraq against Iranian forces; and the probable use of CW agents by the Soviets in Afghanistan indicate a heightened interest in CW as a force multiplier. Also, an offensive CW capability is developed as a deterrent to the military advantage of a potential adversary. For a list of common chemical agents, their characteristics, behavior, and effects see Appendix A. Table 1-4 lists those countries known or suspected of having offensive chemical weapons.

(2) The Russian Republic has the most extensive CW capability in Europe. Chemical strikes can be delivered with almost any type of conventional fire support weapon system (from mortars to long-range tactical missiles). Agents known to be available in the Russian inventory include nerve agents (O-ethyl methyl phosphonothiolate [VX], thickened VX, Sarin [GB], and thickened Soman [GD]); vesicants (thickened Lewisite[L] and mustard-Lewisite mixture[HL]); and choking agent (phosgene). Although not considered CW agents, riot control agents are also in the Russian inventory.

(3) The US is in the process of destroying its stockpiles of CW weapons. Many weapons have already been destroyed and the storage facilities have been rendered safe of all CW agent residues.

d. Toxic Industrial Materials.

Toxic industrial materials can present a medical threat for deployed forces. Toxic industrial materials are comprised of toxic industrial biologicals (TIB), toxic industrial chemicals (TIC), and toxic industrial radiological (TIR) materials. These materials are found throughout the world and are used on a daily basis for commercial and private purposes. Large storage facilities, transportation tankers (over the road and railcars), as well as smaller containers of material, pose a danger to the health of personnel. Accidental spills or releases and terrorist actions can all lead to release of these materials into the environment causing potential casualty producing effects. Medical treatment facilities and nuclear power plants use radioactive materials that can pose a health hazard if accidentally released or used by hostile forces, terrorists, or others to contaminate an area. Biological materials used in medical research and pharmaceutical manufacturing may be used by hostile forces, terrorists, or others to produce casualties. Many TICs produce the same effects on personnel as CW agents. As a matter of fact, many TICs are of the same chemical structure as CW agents. However, there is quite a difference in their potency; in most TICs the potency is much lower. [1-6] For example, chlorine used to treat water supplies has also been used as a CW agent; organophosphate pesticides can cause the same effects as some nerve agents. Hostile forces, terrorists, or others may use RDDs to produce casualties as well. For detailed information on toxic industrial materials see FM 8-500.

## CHAPTER 2
COMMAND AND CONTROL

#### 2-1. General

The US forces may be attacked by or exposed to NBC, TIM, lasers, advanced electronics, high explosives, fuel-air, thermobaric, and conventional weapons; or a combination of these weapons/materiel. Mass casualty situations will be the rule and not the exception. Mass casualty situations can occur anyplace on the battlefield. Combined NBC and conventional weapons injuries may predominate. Command and control (C2) will be essential to prevent casualties and to provide effective HSS. However, C2 (to include HSS C2) elements may be primary targets. Effective HSS in an NBC environment can be accomplished, but only if necessary preparations to survive and to be mission capable are taken. Increased HSS C2 actions are needed to maintain HSS proximity to the supported force; to clear the battlefield; to move and resupply the HSS units, while managing multiple simultaneous mass casualty incidents; and to rapidly evacuate patients. Health service support C2 units must push HSS augmentation to mass casualty sites, clear the site, evacuate the patients to Medical Treatment Facilities (MTFs) that can provide essential care or out of the AO; decontaminate and extract medical forces from NBC contaminated areas and redistribute or redeploy the HSS forces. Within medical units, C2 will be challenged by the use of protective clothing and equipment, the need to move (either to the patients or out of the contaminated area), and obtaining additional support. Health service support advisers and staff officers must provide guidance to commanders on continued duty for personnel who have been exposed to NBC weapons/agents and TIM effects. Leaders must greatly increase coordinating, preplanning, using tactical standing operating procedures (TSOPs), and establishing multiple C2 mechanisms. See Appendix C for guidelines on operational planning for health service support in an NBC or TIM environment. See Appendix D for medical planning guide on NBC casualties. See Appendix E for a sample format of a "medical NBC staff officer appendix to annex Q."

#### 2-2. Health Service Support Command and Control Planning Considerations

a. Battle situational understanding is of great importance on the NBC battlefield. The number of casualties from each NBC attack will overwhelm any single medical unit or MTF causing the medical commander/leader to take action. To the extent possible, the commander/leader should be prepared for the requirement instead of reacting to it. To ensure responsive C2 the HSS plan must consider:

- Likely targets (C2 nodes, main supply routes (MSR), supply nodes, troop concentrations, key terrain features, key forces, or other high value targets).
- Patient estimates (conventional, NBC, and TIM).
- Availability of HSS resources (preestablished support plans).
- Availability of required nonmedical support (patient decontamination teams).
- Ability to maintain operations if C2 is lost at any HSS level.
- Ability to maintain C2 operations when normal communication systems have been disabled due to EMP effects or other system failures.
- [2-2] Ability to maintain C2 operations while the unit is operating in mission-oriented protective posture (MOPP) Level 4 (reduced audio and visual acuity).
- The requirements for immunizations, pretreatments, barrier creams, prophylaxis, insect repellents, and other medical countermeasures to protect the forces.
- The resource requirements for treatment, MEDEVAC, and hospitalization (including care for enemy prisoners of war [EPW]).

b. Clearing the battlefield will require preplanning and close coordination at all levels. Early resuscitation, stabilization, and prompt medical evacuation (MEDEVAC) are mandatory for survival of the sick and wounded.

c. For conventional operations C2 see FM 8-10. Field Manual 8-55 provides HSS planning for conventional operations.

d. Provisions for emergency medical care of civilians, consistent with the military situation. All non-DOD civilian care must be approved by the AO Commander in Chief/senior official and coordinated with the civil affairs unit and/or country team. For eligibility of care determinations guidance, see FM 8-10.

e. For additional information on planning operations in an NBC environment see FMs 8-10, 4-02.10, 4-02.4, 4-02.6, 4-02.283, 8-9, 8-10-6, 8-10-26, 8-284, and 8-285. Higher headquarters must distribute timely plans and directives to subordinate units to ensure that the subordinate unit's HSS plan supports their plan.

#### 2-3. Health Service Support Command and Control Appraisal of the Support Minion

The HSS personnel make an appraisal of the supported mission to determine the expected patient load. Once the appraisal has been accomplished, HSS personnel prepare for the HSS mission by assigning personnel responsibilities. Using triage and EMT decision matrices for managing patients in a contaminated environment improves treatment proficiency. See Figure 2-1 for a sample decision matrix. Training HSS personnel in the use of simple decision matrices should enhance their effectiveness and contribute to a more efficient battlefield HSS process. Prior training for designated nonmedical personnel in patient decontamination procedures will enhance their effectiveness in the overall patient care mission. See Appendix D for planning factors on the estimation of NBC casualties.

#### 2-4. Health Service Support Units

Health service support units must plan, train, and routinely practice mass casualty management. The NBC attack or TIM event will likely be in conjunction with enemy conventional operations. But, the TIM event may be caused by terrorist or belligerent action. There will likely be increased conventional casualties in addition to the NBC/TIM related casualties. The supply and transportation units will be using the MSR in [2-3]support of the combat commander's requirements; thus, impacting on patient MEDEVAC and HSS unit resupply. Communications will be disrupted. Therefore, HSS C2 must plan and prepare for conducting operations with limited or no communications with other HSS organizations.

Figure 2-1. Sample triage and emergency medical treatment decision matrix.

#### 2-5. Movement/Management of Contaminated Facilities

Operations in a contaminated area require the HSS commander/leader to operate with contaminated or potentially contaminated assets. The following provides guidance in determining how to operate with contaminated facilities:

[2-4] a. Fulfill Health Service Support Principles. In making his decision to move or continue to operate with contaminated facilities, the commander/leader must apply the principles of conformity, proximity, flexibility, mobility, continuity, and control. The unit's operation must conform to the tactical commander's operation plan (OPLAN). Health service support must be provided to the tactical unit as far forward as possible; this ensures prompt, timely care. Additionally, the HSS commander/leader must be flexible; his support must be tailored to meet the supported commander's OPLAN requirements. Therefore, HSS assets must be as mobile as the unit they support. Finally, the HSS commander/leader must control his assets. Dispersion on the integrated battlefield may enhance unit survivability; but the HSS commander/leader may not be able to maintain control of his assets, they may become compromised.

b. Decision to Move. The HSS commander/leader (when deciding to move his unit to an uncontaminated area or in support of the tactical commander's plan) must base his decision to move on several factors.

(1) Protection available. What type of protection is available in the new area? Will he need to establish the units' collective protection shelter (CPS) systems, or are indigenous shelters available (for example, buildings, tunnels, caves)? Does the unit have sufficient individual protective equipment for unit personnel?

(2) Persistency. If his unit has been in a contaminated area, is the contamination persistent or nonpersistent? Is the area he will move to contaminated or clean? Persistency determines the MOPP level; the degree of threat; and performance decrement caused by the protective measures used. The level of contamination will determine whether employment of CPS is viable. The MTF may be able to continue to operate at the location by employing CPS. Personnel and patient decontamination must be accomplished before processing into the CPS.

(3) Patients. Before moving the entire facility, the HSS commander/leader must consider the number and types of patients at the MTF; his ability to redirect en route patients to the new MTF location; and his ability to evacuate the patients currently on hand. All patients should be stabilized before movement; but, MEDEVAC must be continued.

(4) Alternate facilities. Alternate facilities may be used (if the facility can be configured to ensure continuity of care or provide a protected area for patients) until the relocating activity is up and operating. This is a viable consideration when CPS is not available or the current location is contaminated with a persistent agent. Patient decontamination cannot be performed in an area heavily contaminated with a persistent agent.

(5) Medical evacuation. Consideration must always be given to the patient. Routes of MEDEVAC must be disseminated to supported and supporting units. The ability to evacuate patients during the move must continue. All MEDEVAC considerations must be addressed before any move.

(6) Mobility. An MTF that is not 100 percent mobile requires movement support. Thus, the commander/leader must coordinate movement support requirements with higher headquarters.

[2-5] (7) Mission. The primary consideration is the support mission of the MTF. The tactical commander requires continuous HSS for his personnel; when a move jeopardizes the quality of care, the move may be delayed.

(8) Sustainability. Hand-in-hand with the mission is sustainability (the ability of the unit to continue its support mission). If the current location of the MTF hinders the unit's ability to sustain its support mission, then the MTFs support to the unit is in question. Similarly, if moving the MTF will result in a disruption of support, then the move may not be viable.

(9) Decontamination. When a nonpersistent agent hazard exists and a CPS is not available, patients may be directed to another MTF until the hazard is gone; or the MTF can move to a contamination free area. Certain facilities may be decontaminated, patient protection procedures applied, and the operation continued. However, an MTF contaminated with a persistent agent requires time-consuming and resource-intensive decontamination operations; it may include replacement of contaminated shelters.

c. Management of Contaminated and "Clean" Facilities. Facilities contaminated with a persistent agent may be too resource intensive to decontaminate. Operating with a combination of contaminated assets and "clean" assets may be necessary. Mark contaminated assets with standard warning tags. Use these assets in contaminated environments and along contaminated routes. Keep clean assets in operation in clean areas. Of primary importance is proper marking and the avoidance of cross contamination.

d. Medical Supplies and Equipment for Patient Treatment. Are sufficient medical supplies and equipment available to perform the anticipated mission? Does the unit have special medical equipment sets available (chemical agent patient decontamination and chemical agent patient treatment medical equipment sets)?

#### 2-6. Leadership on the Contaminated Battlefield

a. Operating on a contaminated battlefield will stress leadership. Heat stress from being in higher levels of MOPP for long periods of time may lead to dehydration. The commander/leader must ensure that his personnel rest, drink, and eat sufficiently to allow them to continue with the mission. In the midst of activity, rest, hydration, and nutrition are often overlooked; however, a good leader will ensure that his personnel needs are met. See FM 21-10 for work/rest cycles and water drinking requirements. Individuals may suffer hyperventilation because of the enclosed feelings. Personnel remaining in MOPP Level 4 around the clock may suffer from increased sleep loss. Use of CPS can reduce this problem by allowing the personnel to rest out of their MOPP gear. Leaders must share leadership responsibilities and delegate responsibilities as much as possible so that each one gets sufficient rest to maintain unit effectiveness. Further, leaders should concentrate on supervision or unit mission, rather than on generation of new procedures during and after an attack. The NBC battlefield will, therefore, require more proactive and dedicated leaders who can balance the needs of their personnel and the mission. Further, leaders will be challenged by an additional logistics burden of providing nontraditional respiratory protection for personnel against TIMs. For detailed information on combat operational stress control (COSC) see FM 8-51 and FM 22-51.

[2-6]

DANGER

The standard NBC protective mask will not protect personnel from most TICs.

b. Leadership must plan for and establish procedures to maintain personnel performance during NBC operations. Personnel performance while wearing MOPP is degrading. At MOPP Level 3 or 4, all but the most basic patient care procedures may have to be suspended because—

- Wearing gloves reduces the ability to grasp and manipulate small items (fine motor skill).
- MOPP impedes the ability to move about (gross motor skills).
- The mask reduces visual fields and acuity (visual skills).
- The mask and hood greatly reduces vocalization and hearing abilities (auditory skills).
- The MOPP creates significant heat and mental stress (stamina). Heat injuries can occur in a very short period of time.

#### 2-7. Homeland Security

Commanders and leaders must plan for and be prepared to support homeland security efforts; especially, for response to chemical, biological, radiological, nuclear, and high-yield explosive (CBRNE) events. Depending upon the location of the event, the response may be to a military installation in support of the weapons of mass destruction—installation support team (WMD-IST) or to an event site off a military installation. Response to a CBRNE event off a military installation will normally require a request for Department of Defense support to the event from the first responders to the event (usually from the incident commander or lead federal agency [Federal Bureau of Investigation or Federal Emergency Management Agency]). See Appendix C for planning considerations.

[3-1]

## CHAPTER 3
LEVELS I AND II HEALTH SERVICE SUPPORT

#### 3-1. General

a. The use of NBC weapons is a condition of battle and HSS personnel must prepare to operate in these environments. Added is the dimension of TIM releases/incidents in the operational area. The importance of preventive medicine (PVNTMED) measures and first aid (self-aid, buddy aid, and combat lifesaver [CLS] support) are even more critical. Heat and stress injuries related to MOPP wear are issues for the HSS leadership as well as the force he is supporting. The stress load on personnel is increased by the concerns of being exposed to TIM releases. Considering that staffing of HSS units is based upon the minimum required to provide support on a conventional battlefield, they will be challenged to provide the same level of HSS in these environments.

b. The HSS leadership must quantify the HSS capability to their commanders. The medical staff must review OPLANS and make recommendations to reduce the number of patients. Medical NBC training programs must stress the essential imperative of immediate decontamination, the need to monitor your buddy for NBC and heat or combat/operational stress injury effects, and the proper use of NBC defense prophylaxis, pretreatments, insect repellents, barrier creams, and immunizations.

c. Maintaining close proximity to the supported force has been a major tenet of HSS doctrine and a critical factor in reducing the mortality rate. Maintaining this proximity and finding a place clean enough to provide necessary care requires intense coordination with the supported force. Alternate casualty collection points, decontamination sites, medical treatment sites, and MEDEVAC routes must be established, coordinated and communicated to the lowest level practical. Communication will be much more difficult, but must be maintained. Timely reports through the HSS technical channels will allow an optimal HSS response. Replacements for HSS front line losses must be rapidly filled after NBC weapons are employed.

d. Contamination (NBC and TIMs) can significantly hinder HSS operations. To maximize the unit's survivability and HSS capabilities and to avoid such contamination, leaders must use—

- Contamination avoidance techniques.
- Alarms and detection equipment.
- Unit dispersion techniques.
- Overhead shelter, shielding material, protective cover, and buildings of opportunity. However, these shelters may not provide protection from chemical vapor or BW hazards.
- Collective protection shelters, if available. See Appendix F.
- Chemical agent resistant coatings on equipment.

e. On the NBC battlefield, as on the conventional battlefield, HSS is focused on keeping soldiers in the battle. Effective and efficient PVNTMED measures, triage, emergency medical treatment (EMT), decontamination, advanced trauma management (ATM), and contamination control in the AO saves lives, assures judicious MEDEVAC, and maximizes the return to duty (RTD) rate.

[3-2]

#### 3-2. Level I Health Service Support

a. Level I (unit-level) HSS may consist of a combat medic section, a MEDEVAC section, and a treatment squad. The treatment squad operates the Level I MTF (battalion aid station [BAS]). Level I HSS is supported by first aid in the form of self-aid/buddy aid and the CLS. See FM 4-02.4 for detailed information on conventional Level I HSS.

b. When operating under an NBC threat or when NBC attack is imminent, the BAS must prepare for continuation of its mission. Should an attack occur or a downwind hazard exist, the BAS must seek out a contamination free area to establish a clean treatment area, or must establish collective protection to continue the mission. Some BASs have Chemically Biologically Protected Shelter (CBPS) Systems. When available, these systems serve as the primary shelter for the BAS; they are operated in the full chemical/biological (CB) mode when attack is imminent or has occurred. See Appendix F for information on establishing a BAS in a CBPS system. When operating in the CB mode only patients requiring life- or limb-saving procedures are allowed entry at the BAS. Patients that have minor injuries that can be managed in the contaminated EMT area of the patient decontamination site will receive treatment in this area. After treatment, these patients will have the integrity of their MOPP restored by taping the damaged area and returned to duty. Patients with injuries that require further treatment, but who can survive evacuation to the Level II MTF will have their MOPP spot decontaminated, their injuries managed, the integrity of their MOPP restored, and be directed to an evacuation point to await transport to the Level II MTF (example, an individual with a splinted broken arm). When patients or personnel are contaminated or are potentially contaminated, they must be decontaminated before admission into the clean treatment area (see FM 3-5 for personnel decontamination procedures and Appendix G for patient decontamination procedures).

#### 3-3. Level II Health Service Support

a. In the brigade, Level II HSS consists of—

- Evacuating patients from the BAS and MEDEVAC on an area support basis from within the brigade support area (BSA).
- Providing area support Level I medical treatment.
- Operating the medical company clearing station (hereafter referred to as the division clearing station [DCS]), which provides a patient holding capability for up to 40 patients for 72 hours. See FM 4-02.6 and FM 8-10-24 for detailed information on Level II conventional operations.
- Providing limited dental service.
- Providing limited PVNTMED support in the areas of medical surveillance, occupational and environmental health surveillance, food service sanitation, water quality control (including NBC contamination surveillance), and communicable disease control.
- Providing limited COSC; these patients are returned to duty as far forward as their condition permits.

[3-3]

b. In the division, HSS is the same as for the brigade, except patients may be evacuated from the BSA DCS, but not evacuated from the BAS.

c. When operating under an NBC threat or when NBC attack is imminent, the DCS must prepare for continuation of its mission. Should an attack occur or a downwind hazard exist the DCS must seek out a contamination free area, or must establish collective protection to continue the mission. The DCS in some medical companies have four CBPS Systems; they are complexed to provide space for DCS operations. These systems are operated in the CB mode when attack is imminent or has occurred. See Appendix F for information on establishing a DCS in CBPS Systems. When operating in the CB mode only patients requiring life- or limb-saving procedures are allowed entry. Patients with minor injuries that can be managed in the contaminated EMT area of the patient decontamination site will receive treatment in this area. After treatment, these patients will have the integrity of their MOPP restored by taping the damaged area and returned to duty. Patients with injuries that require further treatment, but who can survive evacuation to the Level III MTF will have their MOPP spot decontaminated, their injuries managed, and be directed to an evacuation point to await transport to the Level III MTF (example, an individual with a splinted broken arm). When personnel and patients are contaminated or are potentially contaminated, they must be decontaminated before admission into the clean treatment area (see FM 3-5 for personnel decontamination procedures and Appendix G for patient decontamination procedures).

#### 3-4. Forward Surgical Team

Forward surgical teams (FST) are either organic to divisional and nondivisional medical units or are forward deployed in support of divisional or nondivisional medical companies to provide a surgical capability. Field Manual 8-10-25 describes FST operations. However, when forward deployed and NBC contamination is imminent the FST must employ collective protection in order to continue their support mission. When operating in a contaminated area the FST CBPS Systems must be complexed with the DCS CBPS. The FST cannot operate in an NBC environment without the support of the DCS. They do not have the capability to decontaminate patients. All patients are decontaminated in the DCS patient decontamination area. They are then processed into the EMT section of the DCS; where they are triaged and routed to the FST for surgery, if required. See Appendix F for FST employment of collective protection procedures.

#### 3-5. Actions Before a Nuclear, Biological, or Chemical Attack

a. Given the disruption of transportation, communications, and operations during and following an NBC attack, it should be clear that preparation is the key to survival and effectively providing HSS. Preparing a simple and complete TSOP and HSS plan that really integrates NBC is the first step. Critical training for medical personnel before an NBC attack is how to—

- Survive the attack individually and as a unit.
- Operate the Level I or Level II MTF in the environment.
- Effectively care for NBC patients.

[3-4]

b. Even minimal site preparation (nuclear hardening or CB protecting) may improve survival, greatly reduce contamination, and maintain the ability to continue to provide HSS. See the discussion below for more information on each environment. As with other military personnel, HSS personnel must keep their immunizations current; use available prophylaxis against suspect CB agents; use pretreatments for suspect chemical agents; use insect repellents, and have antidotes and essential medical supplies readily available for known or suspected NBC effects. The best defense for HSS personnel is to protect themselves, their patients, medical supplies, and equipment by applying contamination avoidance procedures. They must ensure that stored medical supplies and equipment are in protected areas or in their storage containers with covers in place. One method of having supplies and equipment protected is to keep them in their shipping containers until actually needed. When time permits and warnings are received that an NBC attack is imminent, or that a downwind hazard exists, HSS personnel should employ their CPS (see Appendix F) or seek protected areas (buildings, tents, or other ABOVE ground shelters for biological or chemical attack; culverts, ravines, basements, or other shielded areas for nuclear) for themselves and their patients.

c. Other tasks include:

- Verifying NBC defense HSS inventories are complete.
- Reviewing supported units NBC plans, procedures, casualty collection points, decontamination sites, and resources available to support the HSS mission.
- Coordinating with the S2/G2, S3/G3 and S4/G4 of the supported unit to develop the medical courses of action; to obtain necessary materiel to support extended operations without resupply (MSR contamination or transportation support not available).
- Coordinating with supported units for at least eight nonmedical personnel for patient decontamination augmentation at the Level I and II MTFs.

#### 3-6. Actions During a Nuclear, Biological, or Chemical Attack

While it is possible that the NBC attack will be discrete short events, the more likely scenario is the enemy will use NBC throughout the conflict. The warning and reporting system will provide as much notice as is possible. Using the information provided, HSS personnel will continue their mission by using the best available protected areas. If warned of a nuclear attack, they take up positions within the best available shelter; movement out of these positions will be directed by leadership when it is safe to do so.

#### 3-7. Actions After a Nuclear, Biological, or Chemical Attack

All personnel must survey their equipment to determine the extent of damage and their capabilities to continue the mission. Initially, patients from nuclear detonations will be suffering thermal burns or blast injuries. Also, expect patients and HSS personnel to be disoriented. Nuclear blast and thermal injuries will immediately manifest, most radiation-induced injuries will not be observed for several hours to days. Chemical agent patients will manifest their injuries immediately upon exposure to the agent, except for blister agents. [3-5] Biological agent patients may not show any signs of illness for hours to days after exposure, except for trichothecene (T2) mycotoxins. All patients arriving at Levels I and II MTFs must be checked for NBC contamination. Patients are decontaminated before treatment (see Appendix G) to reduce the hazard to HSS personnel, unless life- or limb-threatening conditions exist. Patients requiring treatment before decontamination are treated in the EMT area of the patient decontamination station. Examples of patient conditions that may require treatment at the contaminated treatment station of the patient decontamination area—

- Massive hemorrhage.
- Respiratory distress.
- Severe shock.

#### 3-8. Logistical Considerations

a. Health service logistics (HSL) personnel must train and prepare to operate in all battlefield situations. Operating in an NBC environment requires the issue of chemical patient treatment medical equipment set and chemical patient decontamination medical equipment set. Expect disruption of MSR and communications systems and plan accordingly. See FM 4-02.1 and FM 8-10-9 for details on HSL operations.

b. The medical platoon (Level I) is authorized two chemical agent patient treatment medical equipment sets and one chemical agent patient decontamination medical equipment set. Each chemical agent patient treatment medical equipment set has enough supplies to treat 30 patients. Each chemical agent patient decontamination medical equipment set has enough consumable supplies to decontaminate 60 patients.

NOTE

The chlorine granules in the chemical agent patient decontamination set are used to prepare the hypochlorite solutions for use to decontaminate patients.

c. The brigade, divisional, and nondivisional medical companies are authorized five chemical agent patient treatment medical equipment sets and three chemical agent patient decontamination medical equipment sets. These medical equipment sets are for use at the DCS patient decontamination station.

#### 3-9. Personnel Considerations

During NBC actions, HSS personnel requirements increase; thus, HSS reinforcement or replacements are necessary. Plans for HSS in a NBC battlefield must include efforts to conserve available HSS personnel and ensure their best use. HSS personnel will be fully active in providing EMT or ATM care; they will provide more definitive treatment as time and resources permit. However, to provide care they must be [3-6] able to work in a shirt-sleeved environment, not in MOPP Levels 3 or 4. Nonmedical personnel conduct search and rescue operations for the injured or wounded; they provide immediate first aid and decontamination. See FM 3-5, for detailed information on personnel and equipment decontamination operations. See FMs 4-02.283, 8-284, and 8-285 for detailed information on treatment of NBC patients.

#### 3-10. Disposition and Employment of Treatment Elements

a. Select sites for the BAS and DCS that are located away from likely enemy target areas. Cover and concealment is extremely important; they increase protection for operating the MTF.

b. Operating a CBPS System in the CB mode at the BAS requires at least eight medical personnel. The senior NCO performs patient triage and limited EMT and minor injury care in the patient decontamination area. One trauma specialist supervises patient decontamination and manages patients during the decontamination process. Two trauma specialists work on the clean side of the hot line and manage the patients until they are placed in the clean treatment area or are sent into the CBPS for treatment. They also manage the patients that are awaiting MEDEVAC to the DCS. The physician, physician assistant, and two trauma specialists provide ATM in the clean treatment area or inside the CBPS. See Appendix F for CPS entry/exit procedures.

c. When the BAS or DCS are receiving NBC contaminated patients, they require at least eight nonmedical personnel from supported units to perform patient decontamination procedures. These facilities are only staffed to provide patient care under conventional operational conditions. Without the augmentation support, they can either provide patient decontamination or patient care, but not both.

d. A patient decontamination station is established to handle contaminated patients (see Appendix G). The station is separated from the clean treatment area by a "hot line" and is located downwind of the clean treatment area or CPS. Personnel on both sides of the "hot line" assume a MOPP level commensurate with the threat agent employed (normally MOPP Level 4). The patient decontamination station should be established in a contamination-free area of the battlefield. However, it may be necessary to establish a patient decontamination station that is collocated with an MTF that is employing a CBPS, in a chemical vapor hazard area in order to decontaminate patients and clear the battlefield before moving the MTF to a clean area. When CPS systems are not available, the clean treatment area is located upwind 30 to 50 meters of the contaminated work area. When personnel in the clean working area are away from the hot line, they may reduce their MOPP level. Chemical monitoring equipment must be used on the clean side of the hot line to detect vapor hazards due to slight shifts in wind currents; if vapors invade the clean work area, HSS personnel must re-mask to prevent low-level CW agent exposure and minimize clinical effects (such as miosis).

#### 3-11. Civilian Casualties

Civilian casualties may become a problem in populated or built-up areas, as they are unlikely to have protective equipment and training. The BAS and DCS may be required to provide assistance when civilian medical resources cannot handle the workload. However, aid to civilians will not be undertaken without command approval, or at the expense of health services provided to US personnel.

[3-7]

#### 3-12. Nuclear Environment

a. The HSS mission must continue in a nuclear environment; protected shelters are essential to continue the support role. Well-constructed shelters with overhead cover and expedient shelters (reinforced concrete structures, basements, railroad tunnels, or trenches) provide good protection from nuclear attacks (see Appendix H). Armored vehicles provide some protection against both the blast and radiation effects of nuclear weapons. Patients generated in a nuclear attack will likely suffer multiple injuries (combination of blast, thermal, and radiation injuries) that will complicate medical care. Nuclear radiation patients fall into three categories:

- The irradiated patient is one who has been exposed to ionizing radiation, but is not contaminated. They are not radioactive and pose no radiation threat to medical care providers. Patients who have suffered exposure to initial nuclear radiation will fit into this category.
- The externally contaminated patient has radioactive dust and debris on his clothing, skin, or hair. This radioactive debris can cause burns if not removed quickly. This usually presents a "housekeeping" problem to the MTF, similar to the lice-infested patient arriving at a peacetime MTF. However, an accumulation of radioactive debris, from several patients admitted to the MTF, may present a threat to other personnel. The externally contaminated patient is decontaminated at the earliest time consistent with required medical care. Lifesaving care is always rendered, when necessary, before decontamination.
- The internally contaminated patient is one that has ingested or inhaled radioactive material, or radioactive material has entered the body through an open wound. The radioactive material continues to irradiate the patient internally until radioactive decay and/or biological elimination removes the radioactive isotope. Attending medical personnel are shielded, to some degree, by the patient's body. Inhalation, ingestion, or injection of quantities of radioactive material sufficient to present a threat to health care providers is highly unlikely.

b. Medical units operating in a radiation fallout environment will face three problems:

- The MTF may be immersed in fallout, requiring decontamination and relocation efforts.
- Patients may continue to be produced from continued radiation exposure.
- The contaminated environment hinders MEDEVAC.

c. Decontamination of most radiological contaminated patients and equipment can be accomplished with soap and water. Soap and water will not neutralize radioactive material. However, it will remove the material from the skin, hair or material surface. See Appendix G for specific patient decontamination procedures. The waste can become a concentrated point of radiation and must be managed and monitored.

d. Commanders and leaders must consider the radiation exposure levels for themselves, their staffs, and patients when operating in or determining if the unit will enter a radiologically contaminated [3-8] area. The commander and leader must establish an operational exposure guide for their unit and personnel. The operational exposure guide (OEG) is established for either battlefield exposures as shown in Table 3-1 or for exposures in stability operations and support operations as shown in Table 3-2. The tables present radiation exposure status (RES) categories; however, they can be used to establish OEGs based on the same exposure criteria.

Table 3-1. Radiation Exposure Status Categories for Tactical Operations

RES-O | THE UNIT HAS HAD NO RADIATION EXPOSURE.
RES-1 | THE UNIT HAS BEEN EXPOSED TO GREATER THAN 0 cGy BUT LESS THAN OR EQUAL TO 75 cGy.
RES-2 | THE UNIT HAS BEEN EXPOSED TO GREATER THAN 75 cGy BUT LESS THAN OR EQUAL TO 125 cGy.
RES-3 | THE UNIT HAS BEEN EXPOSED TO GREATER THAN 125 cGy.

Table 3-2. Radiation Exposure Status Categories During Stability Operations and Support Operations

| RES-O | <0.05 cGy |
| RES-1A | 0.05 TO 0.5 cGy
| RES-1B | 0.5 TO 5 cGy
| RES-1C | 5 TO 10 cGy
| RES-1D | 10 TO 25 cGy
| RES-1E | 25 TO 75 cGy |

#### 3-13. Medical Triage

Medical triage is the classification of patients according to the type and seriousness of illness or injury; this achieves the most orderly, timely, and efficient use of HSS resources. However, the triage process and classification of nuclear patients differs from conventional injuries. See FM 4-02.283 for nuclear patient triage and treatment procedures.

#### 3-14. Biological Environment

a. A biological attack (such as the enemy use of bomblets, rockets, spray or aerosol dispersal, release of arthropod vectors, and terrorist or insurgent contamination of food and water) may be difficult to recognize. Frequently, it does not have an immediate effect on exposed personnel. All HSS personnel must monitor for BW indicators such as—

- Increases in disease incidence or fatality rates.
- [3-9] Sudden presentation of an exotic disease.
- Other sequential epidemiological events.

b. Passive defensive measures (such as immunizations, good personal hygiene, physical conditioning, using arthropod repellents, wearing protective mask, and practicing good sanitation) will mitigate the effects of many biological agent intrusions.

c. The HSS commanders and leaders must enforce contamination control to prevent illness or injury to HSS personnel and to preserve the facility. Incoming vehicles, personnel, and patients must be surveyed for contamination. Ventilation systems in MTFs (without CPS) must be turned off if BW exposure is imminent.

d. Decontamination of most BW contaminated patients and equipment can be accomplished with soap and water. Soap and water will not kill all biological agents; however, it will remove the agent from the skin or equipment surface. See Appendix G for specific patient decontamination procedures.

e. Treatment of BW agent patients may require observing and evaluating the individual to determine necessary medications, isolation, or management. See FM 8-284 for specific treatment procedures for BW agent patients.

f. Medical surveillance is essential. Most BW agent patients initially present common symptoms such as low-grade fever, chills, headache, malaise, and coughs. More patients than normal may be the first indication of biological attack. Daily medical treatment summaries, especially DNBI, need to be prepared and analyzed. Trends of increased numbers of patients presenting with unusual or the same symptoms are valuable indicators of enemy employment of BW agents. Daily analysis of medical summaries can provide early warnings of BW agent use, thus enabling commanders to initiate preventive measures earlier and reduce the total numbers of troops lost due to the illness. See FM 4-02.17 for information of medical surveillance procedures. See FM 8-284 for preventive, protective, and treatment procedures.

#### 3-15. Chemical Environment

a. Consider that all patients generated in a CW agent environment are contaminated. The vapor hazards associated with contaminated patients may require HSS personnel to remain at MOPP Level 4 for long periods. The MTF must be set up in clean areas or employ CPS. If there is liquid agent contamination, or a continued vapor hazard, the MTF should be moved and be decontaminated, mission permitting.

b. Initial triage, EMT, and decontamination are accomplished on the "dirty" side of the hot line. Life-sustaining care is rendered, as required, without regard to contamination. Normally, the senior health care sergeant performs initial triage and EMT at the BAS. Secondary triage, ATM, and patient disposition are accomplished on the clean side of the hot line. When treatment must be provided in a contaminated environment outside the CPS, the level of care may be greatly reduced because medical personnel and patients are in MOPP Level 3 or 4. However, lifesaving procedures must be accomplished. See FM 8-285 for specific treatment of CW agent patients.

[3-10]

c. Decontamination of most chemically contaminated patients and equipment requires the use of materials that will remove and neutralize the agent. See FM 3-5 for equipment decontamination procedures and Appendix G for specific patient decontamination procedures.

#### 3-16. Operations in Extreme Environments

Enemy employment of NBC weapons or TIMs in the extremes of climate or terrain warrants additional consideration. Included are the peculiarities of urban terrain, mountains, snow and extreme cold, jungle, and desert operations in an NBC environment with the resultant NBC-related effects upon medical treatment and MEDEVAC. For a more detailed discussion on NBC aspects of urban terrain, mountain, snow and extreme cold, jungle, and desert operations, see FMs 3-06.11, 31-71, 90-3, 90-5, and 90-10.

a. In mountain operations, passes and gorges may tend to channel the nuclear blast and the movement of chemical and biological agents. Ridges and steep slopes may offer some shielding from thermal radiation effects. Close terrain may limit concentrations of troops and fewer targets may exist; therefore, a lower patient load may be anticipated. However, the terrain will complicate patient evacuation and may require patients to be decontaminated, treated, and held for longer periods than would be required for other operational areas.

b. The effects of extreme cold weather combined with NBC-produced injuries have not been extensively studied. However, with traumatic injuries, cold hastens the progress of shock, providing a less favorable prognosis. Thermal effects will tend to be reinforced by reflection of thermal radiation from snow and ice-covered areas. Care must be exercised when moving chemically contaminated patients into a warm shelter. A CW agent on the patient's clothing may not be apparent. As the clothing warms to room temperature, the CW agent will vaporize (off-gas), contaminating the shelter and exposing occupants to potentially hazardous levels of the agent. A three-tent system is suggested for processing patients in extreme cold operations. The first tent (unheated) is used to strip off potentially contaminated clothing. The second (heated) is used to perform decontamination, perform EMT and detect off gassing. The third (heated) is used to provide the follow on care and patient holding.

c. In rain forests and other jungle environments, the overhead canopy will, to some extent, shield personnel from thermal radiation. However, the canopy may ignite and create forest fires and result in burn injuries. By reducing sunlight, the canopy may increase the persistency effect of CW agents near ground level. The canopy also provides a favorable environment for BW agent dispersion and survival.

d. In desert operations, troops may be widely dispersed, presenting less profitable targets. However, the lack of cover and concealment exposes troops to increased hazards. Smooth sand is a good reflector of nuclear thermal and blast effects; generating increased numbers of injuries. High temperatures will increase the discomfort and debilitating effects on personnel wearing MOPP, especially heat injuries.

#### 3-17. Medical Evacuation in a Nuclear, Biological, and Chemical Environment

a. An NBC environment forces the unit leadership to consider to what extent he will commit MEDEVAC assets to the contaminated area. If the battalion or task force is operating in a contaminated [3-11] area, most or all of the organic medical platoon MEDEVAC assets will operate there. However, efforts should be made to keep some ambulances free of contamination. For conventional MEDEVAC operations see FM 8-10-6 and FM 8-10-26.

b. We have three basic modes of evacuating patients (personnel [litter bearers], ground vehicles, and aircraft). Using litter bearers to carry the patients involves a great deal of stress. Cumbersome MOPP gear, added to climate, increased workload, and the fatigue of battle, will greatly reduce personnel effectiveness. If personnel must enter a radiologically contaminated area, an OEG must be established (see Table 3-1). Radiation exposure records are maintained by the NBC NCO and made available to the commander, staff, and medical leader. The exposure is entered into the individual's medical record. Based on the OEG, the commander and leaders will decide which MEDEVAC assets will be sent into the contaminated area. Again, every effort is made to limit the number of MEDEVAC assets that are contaminated. Medical evacuation considerations should include the following:

(1) A number of ambulances will become contaminated in the course of battle. Optimize the use of resources; use those already contaminated (medical or nonmedical) before employing uncontaminated resources.

(2) Once a vehicle or aircraft has entered a contaminated area, it is highly unlikely that it can be spared long enough to undergo thorough decontamination. However, operational decontamination should be performed to the greatest extent possible. This will depend upon the contaminant, the tempo of the battle, and the resources available to the MEDEVAC unit. Normally, contaminated vehicles (air and ground) will be confined to dirty environments. See FM 3-5 for details on decontamination procedures.

(3) Use ground ambulances instead of air ambulances in contaminated areas; they are more plentiful, are easier to decontaminate, and are easier to replace. However, this does not preclude the use of aircraft. If an air ambulance is deployed into a contaminated area, use it for repeated MEDEVAC missions rather than sending other clean aircraft into the area.

(4) The relative positions of the contaminated area, forward line of own troops (FLOT), and threat air defense systems will determine where helicopters may be used in the MEDEVAC process. One or more helicopters may be restricted to contaminated areas; use ground vehicles to cross the line separating clean and contaminated areas. The ground ambulance proceeds to an MTF with a patient decontamination station (PDS); the patient is decontaminated and treated. If further MEDEVAC is required, a clean ground or air ambulance is used. The routes used by ground vehicles to cross between contaminated and clean areas are considered dirty routes and should not be crossed by clean vehicles, if mission permits. Consider the effects of wind and time upon the contaminants; some agents will remain for extended periods of time.

(5) Keep the helicopter rotor wash in mind when evacuating patients, especially in a contaminated environment. The intense rotor wash will disturb the contaminants and further aggravate the condition. The aircraft must be allowed to land and reduce to flat pitch before patients are brought near. This will reduce the effects of the rotor wash. Additionally, a helicopter must not land too close to a decontamination station (especially upwind) because any trace of contaminants in the rotor wash will compromise the decontamination procedure.

[3-12]

c. Immediate decontamination of rotor wing aircraft and ground vehicles is accomplished to minimize crew exposure. Units include decontamination procedures in their standing operating procedures (SOP). A sample aircraft decontamination station that may be tailored to a unit's needs is provided in FM 3-5.

d. Evacuation of patients must continue, even in an NBC environment. The HSS leader must recognize the constraints NBC places on operations; then plan and train to overcome these deficiencies.

e. To minimize the spread of contamination inside the MEDEVAC aircraft, plastic sheeting should be placed under the litter to catch any contaminant that drips off the patient or litter. The plastic sheeting can be removed with the patient, removing any contamination with it. When plastic sheeting is not available, placing a blanket under the litter will reduce the amount of agent that makes contact with the inside of the aircraft.

NOTE

The key to mission success is detailed preplanning. A HSS plan must be prepared for each support mission. Ensure that the HSS plan is in concert with the tactical plan. Use the plan as a starting point and improve on it while providing HSS.

f. Medical evacuation by United States Air Force (USAF) aircraft will be severely limited until runway repairs and decontamination has occurred. Aerial flights from contaminated areas into uncontaminated airspace and destinations may be impossible for extended periods of time; some nations will not allow patients from contaminated areas to travel through or over their country. Therefore, patient holding on-site (or in theater) for an extended period of time must be anticipated.

g. Patient protection during evacuation must be maintained. Patients that have been decontaminated at the PDS at an MTF will have had their MOPP ensemble removed. The forward deployed MTFs will not have replacement MOPP ensembles for the patients. These patients must be placed in a patient protective wrap (PPW) before they are removed from the clean treatment area for evacuation (see the PPW instruction sheet/PPW label for use of the PPW). The PPW provides the same level of protection as the MOPP ensemble. The patient does not have to wear a protective mask when inside the PPW. The patient is placed inside the PPW that is on a litter. The PPW may also have a battery-operated blower that can provide a reduction of the body heat load and reduce the carbon dioxide level within the PPW. The PPW will provide protection for the patient for up to 6 hours and is a one-time use item. The blower is reusable, remove it and the attachment devices from the used PPW and return it to the patient movement items inventory. See FM 4-02.1 for a discussion on patient movement items.

WARNING

DO NOT place contaminated patients in the PPW. It is for use with uncontaminated/decontaminated patients only.

[4-1]

## CHAPTER 4
LEVELS III AND IV HOSPITALIZATION

#### 4-1. General

a. Many factors must be considered when planning for Levels III and IV hospital support on the integrated battlefield. The hospital staff must be able to defend against threats by individuals or small groups (two or three) of infiltrators and survive NBC strikes or TIM incidents while continuing their mission. This threat may include the introduction of NBC or TIM in the hospital area, the water or food supplies; and the destruction of equipment and/or supplies. On the larger scale of surviving NBC strikes and continuing to support the mission, operating in a contaminated environment will present many problems for hospital personnel. The use of NBC weapons or TIM release can compromise both the quality and quantity of health care delivered by medical personnel due to the contamination at the MTF; constrain mobility and evacuation; and contaminate the logistical supply base. While providing hospital support, consider the following assumptions:

(1) Their location, close to other support assets, makes them vulnerable to NBC strikes and release/dispersion of TIMs.

- Command, control, communications, computers, and intelligence (C4I) infrastructure, logistical nodes, and base clusters are high value targets.
- Most NBC weapons are designed for wide-area coverage. Chemical and biological agents may present a hazard some distance downwind from the area of attack; also, residual radiation may extend for hundreds of kilometers (km) from ground zero.
- The large signature (size, heat, infrared) of a hospital makes it easy to find and target (the assumption is that the hospital is very near the intended targets).
- Hospitals located near road networks and airfields for access to evacuation routes increase their exposure to tactical strikes of NBC weapons and exposure to TIM releases.
- There are ever-increasing numbers of countries and individuals with the ability to manufacture and deliver NBC weapons/agents. This activity increases their use potential at all levels of conflict.

NOTE

When using existing civilian hospitals, the materials for an RDD may be at these hospitals. Exploding the material in place is very practical for a small team of terrorists.

(2) Large numbers of casualties are produced in a short period of time. Many of these casualties may have injuries that are unfamiliar to hospital personnel. These injuries may include—

- Radiation casualties.
- [4-2] Biological casualties.
- Chemical casualties.
- Toxic industrial biological casualties (release of material from biological research facilities).
- Toxic industrial chemical casualties.
- Toxic industrial radiological casualties.
- Chemical agent antidote overdose casualties.
- Combined conventional and NBC injuries.
- Stress casualties mimicking all the above.

(3) In addition to the wounding effects of NBC weapons on troops, their use will have other effects upon the patient care delivery system.

- Follow-on treatment may have to be delayed due to the need for patient and faculty decontamination.
- The arrival of contaminated patients at the hospital will require hospital personnel to perform triage; administer EMT procedures in the patient decontamination area; supervise augmentation personnel performing patient decontamination; and constantly monitor the hospital for contamination. The combat support hospital [CSH] requires at least 20 nonmedical personnel from units within the geographic area/base cluster of the hospital to perform patient decontamination under medical supervision. See Appendix G for patient decontamination procedures.
- Patients may have been triaged and decontaminated at a Level I or Level II MTF. However, all patients must be triaged and checked for contamination as they arrive at the hospital ambulance drop off point. Triage ensures patients receive life- or limb-saving care in a timely manner. If patients are arriving from a suspected NBC contaminated area, they must be decontaminated before admission into the clean treatment area of the hospital. The patient decontamination area is established on the downwind side of the hospital. When the hospital does not have collective protection, the patient decontamination point must be at least 50 yards downwind of the hospital entry point. When the hospital is located inside a base cluster, the patient decontamination area may have to be established some distance from the hospital to prevent contamination of other units in the area. Should this be the case, the patients may have to be transported by ambulance or other vehicle from the clean side (hot line) of the patient decontamination area to the receiving point of the hospital.
- Conditions may mandate the use of nonmedical vehicles to transport casualties to the MTF. The use of these vehicles limits or prohibits en route medical care, but may be the only way to clear the battlefield and ensure timely care of patients at the hospital.

(4) Mission-oriented protective posture reduces the efficiency of all personnel.

[4-3] (5) Without CPS systems, hospitals may operate for a limited time in a nonpersistent agent environment, but are incapable of operating in a persistent agent environment.

- Chemical/biological filters for fixed site hospital ventilation systems will be a critical item of supply. Controlled entry and exit point with sufficient space to permit placement of litter patients and/or numbers of personnel that permit purge of vapors will have to be established. All windows, doors, and other points that may have air leaks will have to be sealed (use tape and plastic sheeting) to enable the facility to have a positive overpressure to keep CB agents out.
- Liquid chemical agents can penetrate the TEMPER in about 6 hours or general purpose (GP) tentage in a shorter period of time. These agents will penetrate the wrappings on medical supplies and equipment; especially, sterilized equipment and supplies, paper-wrapped cotton sponges, and open or lightly closed medications/solutions. They can also contaminate water/food supplies. Therefore, equipment and supplies must be stored in protected areas or under protective coverings.
- Without a CPS system, treatment procedures involving open wounds or the respiratory tract in the presence of a CB agent hazard is limited. Exposing open wounds and the respiratory tract to the agent increases the effects of these agents on the patient.
- Without hardened protection, the hospital, staff, and patients are susceptible to the effects (blast, thermal, radiation, and missiling) of nuclear weapons.
- Hospital electrical and electronic medical equipment is vulnerable to the effects of the EMP produced by nuclear weapons. The EMP is not harmful to humans, animals, or plants, but is very damaging to electronic equipment.
- Hospital equipment is very difficult to decontaminate. Aging (allowing the agent to off-gas) may be the only means of decontamination.
- Hospitals are not kept in reserve. All personnel and equipment losses due to NBC contamination or radiation will have to be replaced.

b. There are currently two force modernization initiative hospital systems in the force structure. The Medical Force 2000 (MF2K) system consists of the CSH, the field hospital (FH), and the general hospital (GH). The Medical Reengineering Initiative (MRI) consists of only one hospital system—the CSH. The MF2K CSH is a corps asset, whereas, the FH and GH are the echelon above corps hospital systems. The MRI CSH will be located in the corps and at echelons above corps. The MRI CSH will replace the FH and GH at echelons above corps. See FM 4-02.10, FM 8-10-14, and FM 8-10-15 for detailed information on these hospital systems.

#### 4-2. Protection

a. Protection of hospital assets requires intensive use of intelligence information and careful planning. The limited mobility of hospitals makes their site selection vital to minimize collateral damage from attacks on other units.

- [4-4] Hospitals must be located as close to the supported units as possible to provide responsive care in support of the tactical commander's plan. However, their limited mobility must be considered when selecting their locations.
- Protective factors (distance from other support units and interposed terrain features) must be balanced against the operational factors (accessibility and time required for patient transport).
- Depending on the weapon systems used, local topography, and meteorological conditions, relatively large portions of the tactical area may remain uncontaminated.

b. Many defensive measures will either impede or preclude performance of the hospital mission. Successful hospital defense against an NBC threat is dependent upon accurate, timely receipt of information via the nuclear, biological, and chemical warning and reporting system (NBCWRS). This information will allow the hospital to operate longer without the limitations and problems associated with the use of the CPS and personnel assuming MOPP Levels 3 and 4. The detailed information (provided in the NBC 5 and 6 reports respectively) on the areas affected and the types of agents used allows the hospital staff to—

- Project the number and types of patients to be expected.
- Establish a patient decontamination area.
- Request patient decontamination assistance.

(1) Protective procedures.

(a) Because most hospital sections operate in sheltered areas (tentage or hard-walled shelter), some protection is provided against vapor, liquid, and particulate (fallout) hazards. Sealing all openings can increase the temporary protection from such hazards; all entries and exits must be curtailed while operating in this mode. Liquid agents will eventually seep through the tent fabric and create a vapor hazard inside the shelter. Locating equipment, such as trucks, under trees or other cover provides similar effects. Setting up hospitals in existing structures (concrete or steel buildings) provides greater protection from hazards and eliminates many decontamination problems. However, without means to seal openings, chemical agent vapors can enter the structure. The addition of CB filtration systems with air locks, that provide overpressure, can provide maximum protection for occupants. Entry and exit procedures must be established to prevent contamination being introduced by personnel and patients entering. See Appendix F for entry/exit procedures when CB filters and air locks are in use.

(b) Concealment and good operations security (OPSEC) will help prevent identification of a unit.

(c) Dispersion is a defensive measure employed by tactical commanders; however, hospital operations limit the value of this technique. One technique that may be used is locating sections of the hospital, such as the motor pool, personnel billets, laundry, and logistical storage, a greater distance from the hospital complex than normal. This will increase dispersion without severely compromising the hospital mission.

[4-5] (d) The MOPP ensemble does not protect against all radiation effects of nuclear weapons. However, it provides some protection against alpha and beta radiation burns. By covering all body surfaces, especially hairy areas, MOPP greatly expedites the decontamination process.

(2) Nuclear.

(a) Most protective measures for hospitals against nuclear attack require engineer and/or intensive logistic support. This support includes placing sandbag walls around tents; digging trenches for patient occupation; or constructing earthen berms (see Appendix H). Occupying existing structures, depending upon their strength and potential flammability, may be the best protection against the effects of a nuclear strike. The remainder of this section presents factors to consider when selecting the protective posture for the hospital against a nuclear attack. Leaving equipment packed and loaded until actually needed for operations will help protect materiel in an NBC environment. In any event the unit must have established an OEG, implemented radiation monitoring, and have contingency plans if these radiation levels are approached or exceeded.

(b) Personnel and patient protection requirements will depend upon the threat (blast, thermal, immediate radiation, or fallout effects). The MOPP ensemble will not protect against internal radiation, but will provide some protection from external radiological contamination.

- If the threat is nuclear fallout, the hospital structure provides protection; the fallout can be brushed or washed off. This allows protection while permitting patient care to continue virtually uninterrupted. A need to relocate the hospital will depend upon the degree of contamination; the amount of decontamination possible; and the projected stay before a normal move in support of operations.
- Hospital tentage alone offers little protection against blast and missiling effects. If the patients are to remain in the tents, they are placed on the floor. Place all equipment on the ground or as low as possible and secure all loose objects. In GP tents, sandbags can be piled around the base of the tent poles to add stability. The tent poles and patient beds should keep the canvas off the ground enough (if the tent collapses) to continue minimal patient care and evacuation; however, be aware of possible tent pole breakage.
- Hospital units are very susceptible to the thermal effect of a nuclear detonation. Tents will not provide protection against the thermal pulse. If the thermal effect (fire) is an impending threat, patients and personnel in tentage must move to trenches, bunkers, or other nonflammable areas.
- Protection factors that can reduce the overall radiation exposure rate for hospital personnel and patients are—
- Time. Reducing the exposure time to the radiation reduces the overall exposure proportionally (cut the time of exposure in half and the overall exposure is cut in half). EXAMPLE: An exposure time of 60 minutes to a dose rate of 100 centigray (cGy) is cut in half (30 minutes) to an exposure rate of 50 cGy.
- Distance. Increasing the distance from the radiation source reduces the exposure in an inverse square relationship (double the distance factor by 2 decreases the exposure factor by 4).
- [4-6] Shielding. Placing material between personnel and patient and the radiation source decreases the dose (the reduction factor is dependent on the type of radiation and the density of the shielding material). Placement of sandbags (two feet wide) around the hospital tents and shelters provides adequate shielding for protection from gamma and x-ray radiation; the thicker the sandbag stacks the greater the protection factor. Tent material is a good shield for alpha particles and adequate shielding from beta particles. See Appendix H for field expedient shielding techniques.

(3) Biological. The most likely use of a biological agent (such as anthrax) is releasing the agent as an aerosol. While such agents may produce large numbers of casualties, initially patients may be seen at the MTF in small numbers, but the number of patients will rapidly increase within a few hours to days. When a trend is identified, the enemy use of a biological agent is suspected. General protective measures are the same as for any infectious disease; specific protective measures are used once the vector or method of transmission has been identified. Designating a single hospital to care for these patients (from a patient care or disease transmission standpoint) may not be necessary. However, if the agent is communicable, consolidating them all at one facility maximizes the use of limited assets and aids in limiting the spread of the disease. Protective measures against biological attack are the same as those for chemical agents when bombs, sprays, or gases are used; see (4) below. The difficulty in rapidly identifying biological agents may force the use of protective measures for longer periods of time. Faced with this situation, a careful evaluation of the mask-only posture is necessary before implementing any level of MOPP. See FM 8-284 for additional information on prevention, protection, and treatment of biological casualties.

(4) Chemical.

(a) Individual protection. When CPS systems are not available, using the correct MOPP level is essential in hospital mission performance. The level of MOPP assumed depends upon the level of threat. An alternative approach for the hospital commander is the use of the mask-only posture. This posture is acceptable when the hazard is from vapor only (except mustard). See FM 3-4 for a description of each MOPP level and mask-only procedures.

- Hospital warning system. The hospital must have a warning system that alerts all personnel of impending or present hazards. This system must include visual and auditory signals; the signals must operate inside and outside the hospital complex. There are numerous problems associated with warning personnel; they include—

- The wide area covered by the hospital operations.
- Some personnel will be asleep at all times of the day or night (two or three shifts).
- The considerable noise from mechanical support equipment; such as the power generation and environmental control equipment.
- Tentage and equipment interrupts line of sight.

- [4-7] Hospital personnel response. When NBC alarms are activated, all personnel (including off duty personnel) report to their duty stations as soon as they are in the designated MOPP level. This allows for 100 percent personnel accounting and provides additional personnel to secure patients and materiel.
- Unprotected hospital areas. Areas of the hospital without CPS are at their best posture with all openings secured and the ventilation systems turned off. For nonpersistent agents (vapor hazards), personnel and patients stay at the designated MOPP level until the all clear signal is given; then normal operations are resumed.

NOTE

Patients with injuries that prevent their assuming a protective posture must be placed in a PPW or immediately evacuated to a clean MTF.

(b) Environmental protection. As noted previously, hospital complexes without CPS offer some protection against liquid or fallout contamination, but little protection against vapor hazards.

- When MOPP Level 1 must be assumed, close and secure all tent flaps, vents, and doors to prevent the entrance of liquids or particles. All hospital personnel outside of shelters assume MOPP Level 4. Cover or move all equipment and supplies into shelters (tents, hard-walled shipping containers), if possible. Placement under thick foliage trees is better than left out in the open. The best policy is to keep all equipment and supplies not immediately needed covered or in closed containers.
- When MOPP Level 3 or mask-only posture is assumed, shut down the hospital's ventilation system to prevent drawing vapors or fallout contamination into the hospital. This measure also provides some protection of the internal environment during the time required for the vapor to penetrate the tentage.

(c) Patient protection.

- Patient protection depends upon prior planning and timely warning of the chemical threat. Each patient's protective mask must be available and serviceable. If the patient came from a contaminated area, the mask must be decontaminated and the filters changed. The mask decontamination and filter change may have to be performed by hospital personnel. If ambulatory patients' medical conditions permit (minimal care ward), they may be able to perform this task. The hospital supply staff must ensure that mask filters are available at the supporting logistics support facility and can be requisitioned to meet this requirement. Check all masks for serviceability as soon as the mission permits, but always before they are needed. Do not wait until the warning has been received to begin checking the mask. Each area must have an established plan for operations (to include assisting patients assuming MOPP or other protective posture) in the NBC environment. Appendix F provides additional information on patient protection.

[4-8]

CAUTION

Remember, personnel must assume MOPP Level 4 before beginning any decontamination process or risk becoming a casualty themselves.

- Hospital staff always mask themselves first, then assist patients in masking. On minimal care wards, most patients can put on their masks. For those who cannot, other patients can assist them after putting on their own masks. On the intermediate care wards, some patients will be able to put on their masks, but many will require assistance. Intensive care and emergency room staff will have to assist their patients in masking.
- Many patients with head and neck wounds or who are on life-support devices will be unable to wear their individual protective masks; these patients must be placed in a PPW. While the PPW has two ports for intravenous or blood infusion lines, the staff may have to adapt for other devices (Foley catheters, traction devices, and cardiac monitor) by using tape and other means to seal the gaps created in the seal around the edge of the PPW. Patients requiring assisted ventilation are at extreme risk, unless their air supply is protected. The sequence of protecting everyone is mask yourself first; assist those patients who can wear their protective masks; and then place patients in the PPW.

(d) Materiel protection. Protection of materiel, especially expendable supplies, requires covers and barriers. All materiel not required for immediate use is kept in shipping containers, medical chests, or under cover (tentage, plastic sheeting, and tarpaulin) for protection against particulate or liquid hazard. Protection against vapor hazard may require multiple barriers through which the vapor must penetrate. For example, intravenous solutions are in their individual plastic bags, in the cardboard shipping box, on a covered pallet, in a hard-walled shelter; such as a military-owned demountable container (MILVAN). This presents four barriers against the vapor hazard. These principles should be used to the maximum extent practical.

#### 4-3. Decontamination

a. Decontamination of nuclear-contaminated personnel, equipment, and the operational site is as follows:

(1) Monitoring equipment is used to detect contamination; the contamination is then removed by brushing or scraping with brooms, brushes, or tree branches. Flushing hard surface contaminated areas with water is also effective in removing nuclear contamination. However, there remains a problem of containing and removing the contaminated water. The best method of containment is to trench the area into a sump for collection of the contamination. This will reduce the area of contamination; however, the level of concentrated radiation may be such that there is an increased hazard to personnel. The collection area must be clearly marked using the standard nuclear hazard signs.

[4-9] (2) Nuclear contamination of the site may require relocating the hospital. Scraping 1 or 2 inches of topsoil from the area, or covering the area with 1 or 2 inches of uncontaminated dirt will not be practical. A need to relocate the hospital will depend upon the degree of contamination; the amount of decontamination possible and the projected stay before a normal move in support of operations. If the hospital is immersed in a high level of radioactivity, the best option may be to abandon it for 48 to 72 hours. After this period the area should be checked and if the radioactivity has decayed sufficiently the hospital may be reoccupied and continue operations or moved to a clean area. The command OEG must be followed if reoccupying or moving the facility.

b. Suspect biological agents should be removed from equipment as quickly as possible, In the absence of agent-specific guidance, clean exposed surfaces using a 5 percent hypochlorite solution or copious quantities of soap and water (preferably hot). Liberally apply the hot, soapy water and scrub all surfaces with a brush. Then rinse the surfaces with hot water. As previously discussed, the soapy water used is contaminated and must be controlled and removed to a safe area. Supertropical bleach (STB) and decontaminating solution Number 2 (DS2, US Army) are effective against most known biological agents because of their caustic nature. If anthrax (or other spore formers) is suspected, repeat the entire decontamination process again to remove the spores. Other standard biological decontamination agents are described in FM 3-5.

CAUTION

1. Keep liquid decontaminants out of equipment with electronic or electrical circuits. Unplug electrical devices before attempting to decontaminate them; prevent electric shock. Some electronic devices maintain an electric charge, even after being unplugged, use extreme care to prevent shock.
2. Soap and water only mechanically remove BW agents. The soap and water solution must be contained to prevent spreading the agent to other personnel, thus causing more casualties.

c. Decontamination of chemical contamination is as follows:

(1) Personnel use their soldier skills and their M295 Individual Equipment Decontamination Kit to decontaminate their personal equipment. The M13, decontamination apparatus, portable, is used to decontaminate vehicles, trailers, and International Organization for Standardization (ISO) shelters. This apparatus uses DS2 (a highly caustic, flammable solution that cannot be used to decontaminate tentage). The DS2 must be washed off after sufficient time has passed for decontamination (see FM 3-5 for details). Water used for NBC decontamination purposes becomes contaminated; therefore, it must be contained in sumps. Dig shallow trenches to channel the water into sumps. This will be difficult in hospital areas because relatively flat sites are needed for hospital complexing, but must be accomplished to reduce the contamination levels in the hospital area.

[4-10] (2) When hospital tentage becomes contaminated, decontamination operations must be considered immediately. Spot decontamination may be effective for small areas; however, gross contamination of TEMPER and GP tentage is best decontaminated by aging. Without CPS and with persistent agent contamination that absorbs into the tentage and presents a continuing vapor hazard, the hospital stops receiving patients and evacuates all patients as quickly as possible. When large portions of the hospital are contaminated, personnel decontaminate all equipment possible and relocate to a new site, leaving the contaminated equipment to age or to be decontaminated by a specialized unit. When small portions of the hospital are contaminated, the contaminated portions are removed to another location for decontamination; hospital operations are continued, but at a lower operational level. For detailed equipment decontamination procedures, see FM 3-5.

NOTE

Liquid decontamination material must not be used on electrical or electronic components of equipment. Liquid decontaminants can damage the equipment; thus making it inoperable and not available for patient care or transport. The use of liquids to decontaminate electronic equipment could also potentially result in injury or electrocution of personnel.

(3) Each US Army hospital is issued five chemical agent patient treatment MES and three chemical agent patient decontamination MES, Chemical Agents Patient Decontamination, for use in decontaminating patients. Each hospital must decontaminate and treat its own personnel who become casualties; chemical casualties from units in its general area; or contaminated patients received from lower level MTFs. See Appendix G for patient decontamination procedures and for establishment of a patient decontamination and treatment station.

#### 4-4. Emergency Services

a. Providing emergency services will be complicated by several factors:

- Varying levels of treatment received prior to arrival at the hospital.
- Caring for combined conventional wounds and NBC agent effects.
- Managing heat-related complications associated with MOPP/PPW use.
- Controlling psychological effects caused by biological and chemical agents, the impact of NBC weapons, or the isolation of MOPP gear or PPWs.
- Having EMT personnel working at the arrival point, decontamination site, and in the hospital EMT area.
- [4-11] Conducting triage and providing patient care while in MOPP gear.
- Supervising supported units decontamination augmentation personnel. These personnel will most likely be of any military occupational specially (MOS), except medical. They will use hospital equipment and supplies to decontaminate patients.

b. Contaminated patients must be triaged in the decontamination area that is established at the hospital. Contaminated patients WILL NOT be brought into the clean EMT area until decontaminated. All patients are screened for contamination. Based on the findings, the patient is routed to the contaminated triage station, or to the clean triage station. Contaminated patients are triaged, then routed to the decontamination area, or to the contaminated treatment area. Patient admission to the clean treatment area may be delayed; however, life- or limb-saving care is provided in the contaminated treatment area before decontamination.

#### 4-5. General Medical Services

The provision of general medical services in the hospital will be continued with minimal interruptions in the NBC environment. The noninvasive nature of these services allows their continuation at most MOPP levels. However, some general medical services will be constrained by MOPP Levels 3 and 4 and the mask-only posture. These constraints may include, but not be limited to—

- Communication limitations.
- Loss of the oral route for administering medications to patients.
- Limited ability to accurately evaluate the eyes, nose, and mouth of patients wearing a protective mask.
- Reduced ability to perform examination/assessment of patients in PPW or MOPP Levels 3 and 4.
- Inability to provide oxygen therapy or ventilator support to a patient in a vapor hazard environment, unless a CB filter-supported respirator is available.
- Logistical constraints based upon the fact that key areas such as dietetics, supply, and laundry are not in the CPS. These services may be reduced or delayed in the NBC environment. See Appendix F for Information on patient feeding under NBC conditions.

#### 4-6. Surgical Services

a. Surgical services will be severely limited in the NBC environment. At any level above MOPP Level 0, without a CPS system surgical services are halted except for life- or limb-saving expedient procedures. Surgery cannot be safely performed outside a CPS due to a variety of factors including—

- [4-12] Lack of protected ventilation for patients during and after surgery.
- Inability to maintain a sterile field while using MOPP gear.
- Direct access for agents through open wounds to the circulatory and respiratory systems.
- Decreased dexterity and vision resulting from MOPP gear use.
- Inability to quickly place the patient in a PPW should the need arise.

b. Due to the relatively high number of trauma cases, hospital services may be severely constrained by NBC contamination. The hospital location and the possible need for relocation are two major planning considerations for the command staff.

c. Patient accounting and medical regulating are critical factors in the transfer of patients from a hospital without a CPS that must move out of an NBC environment. Hospitals without CPS stop receiving patients when a persistent hazard is identified; patients on hand are protected and transferred to a clean MTF.

#### 4-7. Nursing Services

Providing nursing care in a hospital without CPS is influenced by the amount of protective gear worn by the nursing staff and the patients. The patients may be in their MOPP gear, in a PPW, or wearing only their protective mask; any of which will interfere with care. The nursing staff will wear the same level of protection as the patients.

a. Direct assessment of a patient's vital signs is extremely limited at MOPP Levels 3 or 4; however, a carotid artery pulse can be taken by palpating the neck area. The patient's respiratory rate and level of consciousness may be assessed visually. Palpitation of the blood pressure through a PPW may be possible if it is relatively strong, or at least in the normal range. The patient's temperature cannot be monitored; this is an area of concern due to the possibility of heat stress.

b. Only gross neurological signs can be assessed through the PPW or when the patient is in MOPP Levels 3 or 4. However, even this assessment is complicated by the presence of miosis and by the health care provider's mask. Urinary output and cardiac monitoring is continued uninterrupted for patients wearing a mask only and for patients in the PPW.

c. Oral hygiene and bathing are postponed until a safe environment is available (MOPP Level 2 or less). All toileting will occur within the hospital complex using ISO contained latrines, chemical toilets, bedpans, urinals, buckets, or containers with plastic liners. Waste from improvised containers must be placed in containers with covers or in plastic bags and sealed to control odors and prevent spread of infectious material within the facility.

[4-13] d. At MOPP Levels 3 and 4, feeding must be postponed. A nutritional assessment is needed to determine how long each patient can tolerate a fasting state when MOPP Level 3 or Level 4 remains in effect for over 24 hours.

e. Intravenous (IV) medications are mixed in a clean area and then transported in a protective wrap (multilayers of plastic, medical chest, or layered cardboard) to the user. However, IV solutions, blood, and injections can be given to patients on an unprotected ward. Normally, oral medications are only given at MOPP Level 2 or lower.

f. Treatment procedures that have the potential of contaminating the patient's pulmonary or circulatory systems are conducted only at MOPP Level 2 or below. However, EMT procedures may have to be performed in the contaminated treatment area, or the patient decontamination area.

g. Continuous oxygen therapy requires a collective protection environment or a CB filter supported respirator.

h. Delivery of nursing care at MOPP Level 3 or Level 4 is limited due to the sensory restrictions of MOPP gear. Time is taken to reassure the patients on a personal basis, as much as possible, and by routinely monitoring the ward environment. Communications are difficult and identities are masked. Maintain the identity of personnel by using handwritten name tags for staff and patients (including patients in PPW).

i. As with all procedures, the time required for record-keeping rises markedly at MOPP Level 3 or Level 4. Contaminated paperwork cannot be evacuated with the patient. Transcribe essential information onto uncontaminated documents for evacuation with the patient. A record of patient exposure time to a contaminated area is prepared to assess the cumulative risk to the patient.

#### 4-8. Conventional Operations

For conventional operations of hospitals in a field environment see FM 4-02.10, FM 8-10-14, and FM 8-10-15.

## CHAPTER 5
OTHER HEALTH SERVICE SUPPORT

### Section I. PREVENTIVE MEDICINE SERVICES

#### 5-1. General

On the integrated battlefield, PVNTMED services will be in greater demand than at any other time, especially under BW conditions. Preventive medicine personnel will be called upon to assist the commander in determining the health hazards associated with nuclear fallout; the safety of drinking water in an NBC environment; as well as determining when to use prophylaxis, pretreatments, immunizations, and other PVNTMED measures (PMM) associated with NBC warfare. Preventive medicine personnel must be aware of the medical threat in the AO. They must continually update their medical surveillance activities to identify disease trends (endemic and epidemic), potential disease vectors, and the susceptibility of troops to these diseases. Under NBC conditions, diseases may manifest that exist in the area, but were not being transmitted to personnel. However, due to the reduced health status of personnel from exposures to or from stress-related NBC conditions, the troops begin to suffer their effects. The appearance of diseases or arthropods not known to exist in the AO are indicators that BW agents have been used. For details on PVNTMED operations, see FM 4-02.17.

#### 5-2. Disease Incidence Following the Use of Nuclear, Biological, and Chemical Weapons

a. Determining Factors. Factors of prime importance in determining the nature and severity of the disease effects are—

- Immunization status of personnel.
- Population density.
- Degree of industrialization in the operational area.
- Availability of food supplies.
- Availability of water.
- Climate.

Finally, the manner and situation in which nuclear weapons are used are of importance. A single weapon detonated in a socially stable area will have far less serious effects than a detonation in an area where combat has already disrupted the social stability. At Hiroshima and Nagasaki, Japan (excellent examples of the first type of situation), the survivors who could get away were able to obtain food, shelter, and care from surrounding intact areas. With prolonged combat operations, such intact areas would not be available, resulting in no food, shelter, or care for survivors. There will be a breakdown in social order and there will be a lack of effective medical support; including PVNTMED functions and facilities.

[5-2] b. Disease Incidence. Without PVNTMED capabilities, increased incidence and morbidity from diseases will follow. Some diseases will predominate in incidence, depending upon the geographical areas involved and the endemic diseases present.

(1) In urban areas in temperate climates, several diseases are epidemic threats. These epidemic threats may include—

- Dysentery (due to a variety of pathogens).
- Rickettsial diseases, particularly typhus and scrub typhus.
- Hepatitis.
- Tuberculosis.
- Sexually transmitted diseases.
- Malaria and cholera (in many parts of the world).

(2) There are several reasons for the increased risk of disease including, but not limited to—

- Crowding of surviving populations with limited sanitary facilities, such as was seen in Europe at the end of World War II.
- A lack of prophylaxis and immunizations with resultant increases in the susceptible faction of a given population.
- A lack of pest management.
- The effect of irradiation on susceptibility to infection. With the high levels of fallout covering wide areas, a large number of people will sustain sublethal whole-body doses of irradiation. The interaction of irradiation with infections is not clear; but it may be the result of latent infections manifesting and decreased resistance to infection. The result is an increased incidence of disease.
- The ecological imbalance and host-parasite relationship following the use of nuclear weapons. Each class and order of animals has marked differences in sensitivity to irradiation. Arthropods, for example, are much more resistant than are vertebrates. The normal balance between arthropods and birds that prey upon them in a given area may be severely upset, producing a marked overgrowth of the arthropods. If the arthropods include vectors of disease there would be a serious increase in disease hazards. If there is an increase in arthropods that destroy vegetation there would be a serious destruction of food crops.
- The introduction of a BW agent in an AO in which the disease organism is endemic or epidemic can increase the risk level for exposed personnel.

[5-3]

#### 5-3. Preventive Medicine Section

The PVNTMED sections of the brigade, divisional, and nondivisional medical companies perform analysis on water sources and supplies to determine the presence or absence of NBC/TIM contamination; see Appendix I for additional information. Based upon their findings, the water is released for consumption, or is restricted from use until it is treated (usually by water production personnel using the reverse osmosis water purification unit [ROWPU]). They also collect water samples for suspect biological agent contamination for supporting medical laboratory analysis (see Appendix B). They conduct medical surveillance activities, to include occupational and environmental health threat surveillance. They conduct limited entomological surveys to determine the existence of disease-vectoring arthropods in the AO. They inspect food service facilities to determine the extent, if any, of NBC contamination. They evaluate the unit's—

- Immunization status.
- Use of prophylaxis for specific diseases (such as antimalarial tablets) (see FM 4-02.33), for nuclear radiation exposure (such as granisetron for nausea and vomiting) (see FM 4-02.283), and for BW agents (such as Ciprofloxacin for postexposure chemoprophylaxis for Anthrax) (see FM 8-284).
- Use of nerve agent pyridostigmine pretreatment tablets (see FM 8-285), if warranted.
- Application of personal hygiene and field sanitation procedures (FM 21-10/MCRP 4-11.1D).
- Based upon their findings, they provide recommendations for corrective actions to the commanders. They assist in training US Army unit field sanitation teams (FM 4-25.12); they are not members of the unit field sanitation team. They conduct medical surveillance activities for their command (FM 4-02.17).

#### 5-4. Preventive Medicine Detachment

The PVNTMED detachment provides PVNTMED services on an area support basis to units within their assigned AO. These services include, but are not limited to—

- Conducting water surveillance, including NBC contamination. Collecting water samples suspected of NBC/TIM contamination for analysis by supporting medical laboratory (see Appendix B).
- Performing food service sanitary inspections.
- Conducting medical surveillance and providing epidemiological consultation.
- Conducting pest (arthropod and rodent) surveys and surveillance.
- Conducting arthropod control operations. The aerial spraying missions are dependent upon availability of helicopter support.
- Conducting occupational and industrial hygiene surveys.
- [5-4] Advising commanders on the application of PMM.
- Training the supported units' field sanitation teams.

### Section II. VETERINARY SERVICES

#### 5-5. General

The US Army Veterinary Service is the Executive Agent for veterinary services to all Services within the DOD. They ensure that food and bottled water supplies are safe and provide veterinary medical and surgical care for government-owned animals throughout the AO. On the integrated battlefield, their role is particularly important; the potential for food supplies becoming contaminated with NBC agents is high. For detailed information on provision of veterinary services see FM 8-10-18.

#### 5-6. Food Protection

Food may become contaminated from enemy employment of NBC weapons/agents or from terroristic contamination of food procurement facilities and food supplies. The NBC agents may be introduced during production or in the storage area of the procurement facility; while the product is in transit; at the military storage facility; or at the unit food service facility. Regardless of where the agent is used, the effect is the same; personnel will become ill or die if they consume the contaminated food. To ensure food safety, veterinary personnel inspect and monitor food from its procurement until it is issued to the consumer. Throughout the AO, all Services (Army, Navy, Marine, and Air Force) logistics and food service personnel must take precautions to protect subsistence from contamination.

#### 5-7. Food Decontamination

Veterinary personnel are involved in the detection and monitoring of NBC contaminated rations; before use, they must inspect all food suspected of being contaminated with NBC agents. Appendix J provides guidance on food decontamination procedures. Veterinary personnel provide advice on the decontamination of food to unit personnel owning the food, or personnel performing the food decontamination. Depending on the type of contamination and packaging, the food may be—

- Consumed without being decontaminated.
- Decontaminated and then consumed.
- Destroyed.

Some items may be held to allow time for natural decay of nuclear or chemical contamination before consumption. The commander, with advice from veterinary personnel, makes the decision on the disposition of the food. However, veterinary personnel make the final determination of food safety.

[5-5]

#### 5-8. Animal Care

Veterinary personnel are concerned with the protection of government-owned animals and animals being procured for consumption. Animals must be protected from NBC contamination, whenever possible. Animals should be moved into enclosures to protect them as much as possible from contamination. Protective equipment is not available for military working dogs; however, protection of the animal's feet and body must be considered. When military working dogs must cross a contaminated area, protect their feet by using butyl rubber material to improvise booties. Since CPS systems are not available, animal treatment facilities must be established in contamination free areas. Veterinary treatment personnel must remain in MOPP Level 4 when caring for NBC animal casualties until the animals have been decontaminated. The treatment of military working dog NBC casualties is outlined in FM 8-10-18.

### Section III. LABORATORY SERVICES

#### 5-9. General

Laboratory services must continue their support role even under NBC conditions. For the provision of clinical and diagnostic support, the facility must be located in a contamination-free area or be inside collective protection. Designated laboratories within the theater will analyze NBC samples/specimens (including in theater field confirmation identification of biological agents by evaluating specimens from symptomatic patients and animals and environmental samples collected from the AO). See Appendix B for procedures in collecting biological samples/specimens, handling/packaging, maintaining chain of custody, transporting samples/specimens, and analysis.

#### 5-10. Level II

Laboratory support at this level is extremely limited; it consists of laboratory procedures in direct support of MTF and FST activities. Laboratory personnel prepare collected suspect NBC specimens for submission to the supporting laboratory for analysis; the specimens are forwarded to supporting medical laboratories (Appendix B).

#### 5-11. Level III

Laboratory support in a CSH is intended for providing clinical laboratory support and is primarily in support of acute surgical cases, blood services, and statim (STAT) services required for intensive care operations. Only extremely limited microbiology services (parasitological exams and gram stains) are provided. In a mature theater, the microbiology services may be augmented to include limited cultures and sensitivity testing. Patients with documented or suspected exposure to NBC weapons/agents will be medically evaluated, specimens will be collected, packaged, and have chain of custody established. The specimens will be forwarded through technical channels to the supporting medical laboratory (such as the theater Army medical laboratory [TAML]) for analysis. See Appendix B for specimen collection, packaging, chain of custody, and processing requirements.

[5-6]

#### 5-12. Level IV

a. Clinical Laboratories. The clinical laboratories in the combat support, field, and general hospitals have the ability to perform a general, but limited, array of analytical procedures in hematology, urinalysis, chemistry, microbiology, serology, and blood bank. Patient specimens of suspected biological or chemical agent exposures are forwarded through technical channels to the supporting medical laboratory. See Appendix B for sample/specimen collection, packaging, chain of custody, processing, and transporting requirements.

b. Field Laboratories.

(1) Theater Army Medical Laboratory. The TAML is the specialized echelons above corps (EAC) laboratory that provides clinical and nonclinical medical laboratory support. When equipped and staffed, the TAML provides in-theater field confirmation identification of NBC samples or specimens. Using sophisticated equipment and methods, the TAML has the capability to detect and identify NBC agents in a variety of specimens/samples (such as human, air, soil, water, animals, vegetation, and food). Direct support from continental United States (CONUS)-based laboratories aids the TAML with identification of NBC agents. Command decision on use of protective/preventive measures and patient care may be based on the TAML findings. Proper collection, packaging, and rapid shipment of specimens by MTFs and samples from other sources will ensure effective, timely, and accurate laboratory analyses.

(2) Area Medical Laboratory. The Area Medical Laboratory (AML) is the specialized laboratory within the theater that provides nonclinical medical laboratory support. The AML can be deployed in the corps or to EAC for support missions. When fielded, the AML will replace the TAML in the force structure. The AML provides in-theater field confirmation identification of NBC samples or specimens. Using sophisticated equipment and methods, the AML has the capability to detect and identify NBC agents in a variety of specimens/samples (such as human, air, soil, water, animals, vegetation, and food). Direct support from CONUS-based laboratories aids the AML with identification of NBC agents. Command decision on use of protective/preventive measures and patient care may be based on the AML findings. Proper collection, packaging, and rapid shipment of specimens by MTFs and samples from other sources will ensure effective, timely, and accurate laboratory analyses.

#### 5-13. Level V (Continental United States)

Designated Level V medical laboratories perform analyses to provide definitive identification of suspect biological agents for the President and Secretary of Defense purposes. The definitive identification of suspect biological agents also aids commanders in the AO in maintaining the health of their command.

#### 5-14. Field Samples

Chemical corps personnel collect environmental, air, soil, and vegetation samples. Preventive medicine personnel collect samples from drinking water sources and supplies. Veterinary personnel collect samples from food supplies and medical specimens from animals. All other units collect soil, vegetation, and small [5-7] animal samples for laboratory analysis. Samples are subjected to initial screening with rapid test kits and in-theater confirmatory identification at the supporting medical laboratory. The President- and Secretary of Defense-required definitive identification is performed at the designated Level V medical laboratory. Comprehensive databases will be maintained to provide historical testing results and will aid in the AO commander's decisions to conduct operations in an NBC environment. See Appendix B for specific procedures for sample collection, packaging, transporting, maintaining chain of custody, and analysis.

### Section IV. DENTAL SERVICES

#### 5-15. General

Dental service support is provided in the AO at Levels II, III, and IV. Because of their location close to main supply routes and other support assets, dental units are vulnerable to an NBC strike. Nuclear, biological, and chemical operations have an impact at all levels; thus, dental units must be prepared to survive on the integrated battlefield. Defense against NBC weapons must be included in the dental unit's TSOP. Individual and collective tasks must be intensely trained on a regular basis; survival depends on the ability of personnel to use basic survival skills against an NBC attack. For details on provision of dental services, see FM 4-02.19.

#### 5-16. Mission in a Nuclear, Biological, or Chemical Environment

The overall mission of dental units to provide dental services is greatly affected in the aftermath of an NBC attack. First, the unit must survive the attack and rapidly recover from its effects. Secondly, in the event of mass casualties, the dental patient care effort must be redirected from dental treatment to the alternate wartime role of augmenting the adjacent MTF. Dental units do not possess CPS; therefore, providing dental services in an NBC environment will be limited to the treatment of maxillofacial emergencies requiring immediate attention. This care will be provided at an MTF with a CPS.

#### 5-17. Dental Treatment Operations

As a general rule, in the aftermath of an NBC attack, dental treatment operations cease until deliberate decontamination of the unit and its equipment has been accomplished. Only maxillofacial injuries of an immediate life-threatening nature should be considered for treatment. After an attack, the resources of the dental treatment facility (DTF) are redirected toward support of any mass casualty situation that may have been generated at an adjacent MTF, or toward decontamination and relocation to a noncontaminated area.

#### 5-18. Patient Treatment Considerations

The only category of dental treatment appropriate in an NBC environment is emergency; and then, only those emergencies of an extreme nature which demand immediate attention. The most likely condition requiring such attention would be maxillofacial trauma and would most likely be treated at an MTF rather [5-8] than a DTF. Although the likelihood of a requirement to treat dental patients in an NBC environment is extremely low, DTFs must have a plan in the event that such patients do present.

a. Patient Decontamination. Decontamination of patients, dental patients included, is an absolute requirement before admission into a clean MTF. Contaminated patients are triaged and decontaminated before treatment (except for life- or limb-saving care). Both triage and decontamination should be accomplished as far forward as possible. Specific details on patient decontamination are in Appendix G. It is important to note that normally patient decontamination is not performed by medical or dental personnel. Initial decontamination at the basic skill level is accomplished at the casualty's unit. Detailed patient decontamination is accomplished by the patient decontamination teams (made up of nonmedical personnel from the supported units) that are supervised by medical personnel at the MTF.

b. Patient Decontamination at Dental Treatment Facilities. Neither dental units nor their DTFs are equipped for patient decontamination. Any contaminated patients arriving at a DTF requiring urgent attention must be directed or evacuated to the nearest MTF with a patient decontamination capability.

#### 5-19. Patient Protection

Dental treatment facilities must also consider the need to protect patients in their care in the event of an NBC attack, or when the threat of an attack is high. Special consideration must be made for maxillofacial patients whose condition prevents them from wearing their protective mask.

a. Immediate Response. In the event of an attack or when the alarm sounds, dental treatment providers immediately cease work and mask. The patients should do likewise. Only after putting on their own masks, do the dental treatment providers assist the patient, if necessary, by removing materials that impede the patient's masking. Only those materials that impede masking or may compromise the airway (such as rubber dam frames or impressions) are removed, the rest are left in place until the all clear is sounded. Special attention must be given to patients who may have been medicated into a less than fully conscious state, or are otherwise incapacitated.

b. Mission-Oriented Protective Posture Considerations. The MOPP level should be taken into account when determining the category and extent of dental treatment to be provided. Patients, including those seated in the dental chair, should be at the MOPP level prescribed for the DTF by its parent headquarters. Dental treatment at MOPP Levels 3 and 4 is, of course, impossible because of the requirement to wear the protective mask; however, treatment is still possible at MOPP Levels 0, 1, and 2. Treatment at MOPP Level 2 should be limited only to emergency care requiring urgent attention. At MOPP Level 1, most types of dental emergencies can be accommodated; however, only minimal essential treatment should be undertaken in order to reduce risk of the patient being caught in a compromised state. At MOPP Level 0, the provision of dental treatment generally is not limited. However, the degree of the NBC threat forecast for the area should be considered before undertaking extensive treatment.

c. Maxillofacial Injuries. Patients with maxillofacial injuries that prevent proper fit and seal of the individual protective mask must be placed in a PPW. Though patients with these types of injuries are [5-9] most likely to be found only in MTF channels, DTFs should nevertheless be prepared in the event a patient presents to the DTF. Since the DTF does not have any PPWs; these patients should be immediately evacuated to the adjacent MTF for treatment.

### Section V. COMBAT OPERATIONAL STRESS CONTROL

#### 5-20. General

When operating under the threat of or under actual NBC conditions, soldiers will be at a high risk of suffering combat operational stress-related conditions. The invisible, pervasive nature of these weapons creates a higher degree of uncertainty and ambiguity, presenting fertile opportunities for false alarms, mass panic, and other maladaptive stress reactions. Therefore, commanders and leaders must take actions to prevent and reduce the numbers of combat operational stress cases in this environment. The symptoms and physical signs caused by excessive stress are similar to some signs of true NBC agent injury. In World War I, inexperienced units initially evacuated two stress cases for every one true chemical casualty. Some minor chemical casualties also had major stress symptoms. Therefore, far forward triage is essential to prevent over evacuation and loss of the individual to the unit. For details on provision of COSC see FM 8-51 and FM 22-51.

#### 5-21. Leadership Actions

a. Keep Personnel Informed of the Situation. Keep information flowing, dispel myths, and control rumors by—

- Discussing the situation and its possible long-term implications honestly.
- Maintaining the perspective that the best chance for mission accomplishment is assured when the unit and the Army stays mission focused.

b. Train Soldiers to Survive. Use training procedures that—

- Tell the lessons of history on NBC weapons employment. Show that the enemy's use of NBC weapons/agents will not give him enough advantage to justify the risk to his forces.
- Increase the chance of surviving and winning should the enemy use NBC weapons/agents.
- Emphasize the buddy system as a means of keeping watch for each other. Personnel must always seek buddy aid before taking additional antidotes. This will reduce the numbers of individuals using their antidotes when not needed; and prevent the increased heat stress caused by the effects of atropine on the body's cooling capabilities.

[5-10] c. Put Nuclear, Biological, and Chemical Defense in Realistic Perspective. Continuously strive to maintain a realistic perspective in the unit by—

- Comparing the risks of the threat with the increased risk of facing the conventional threat in varying levels of MOPP. The decision to initiate a MOPP level should be like deciding how much cover is needed to protect a unit from conventional weapons.
- Choosing the lowest MOPP level that protects the unit, yet permits accomplishment of the mission. Do not try to be 100 percent safe from chemical attack if it means that there is—

- Only a small chance of mission accomplishment.
- A high probability of being killed by the enemy.
- A high personnel loss due to heat injury.

d. Train in the Protective Mask. Train in the protective mask often. It takes repeated wear and time to acclimate and get over the claustrophobic feeling of wearing the mask. The training can be conducted during a variety of activities.

- Have personnel wear the mask often in garrison or during lulls in other activities, even at desk jobs. If on average, one person in five wears the mask, on a rotational basis, at any given time, everyone will quickly become accustomed to wearing it.
- Periodic prolonged wear (8 hours or more) helps soldiers gain confidence and realize that they can tolerate the discomfort.
- Have personnel wear the mask while performing combat-related (mission essential) tasks.

e. Train in Mission-Oriented Protective Posture Level 4. Training in MOPP Level 4 (or simulated MOPP 4, which is to overdress while wearing the protective mask, overboots, and gloves) will increase personnel confidence in their ability to wear the ensemble.

f. Ensure Sleep Plans are Safely Practiced. Have everyone practice wearing the mask while sleeping. Ensure personnel only sleep in safe places; do not allow personnel to sleep under or near vehicles or other motorized machinery. Require ground guides for all vehicles in the unit bivouac area. Ensure that each individual get at least 4 hours of uninterrupted sleep during every 24-hour period, mission permitting (See FM 21-10).

#### 5-22. Individual Responsibilities

a. Follow Orders. By following orders, individuals can increase their ability to cope with and prevent combat operational stress-related conditions. Coping with the stresses of an NBC environment requires extra individual action. Concentrate on the positive aspects of survival, not the negatives of illness or death.

[5-11] b. Train. Use every opportunity to wear the protective mask or the entire MOPP ensemble during training, when permitted. You build self-confidence and endurance by frequently training with your protective mask, or at MOPP Level 4. Perform refresher training in basic NBC survival skills.

c. Use Buddy System. Use the buddy system to increase your ability to survive. Service members looking out for each other give a sense of security that relieves stress. Looking out for each other improves every individual's ability to perform his duties.

#### 5-23. Mental Health Personnel Responsibilities

a. Staffing for Combat Operational Stress Control. Combat operational stress control is provided by the following activities or units:

- Brigade mental health section.
- Division mental health section.
- Area support medical battalion mental health section.
- Neuropsychiatric ward and consultation service of each CSH, field hospital, and general hospital.
- Medical detachment, COSC.
- Medical company, COSC.

b. Conduct Preventive Activities. In an NBC environment, prevention is the most economical means of controlling combat operational stress reactions. Mental health personnel must begin consultation services before NBC weapons/agents have been employed.

c. Control Stress Reactions. Individuals with combat operational stress reactions require prompt intervention. The evaluation of over-stressed personnel is difficult but not impossible when both the soldier and the evaluator are in MOPP. The primary method of mental health evaluation is the interview and mental status examination. For details on controlling stress reactions, see FM 8-51.

### Section VI. HEALTH SERVICE LOGISTICS

#### 5-24. General

As in all combat situations, the protection of medical supplies and equipment on the integrated battlefield is a must. Without medical supplies and equipment, HSS will be greatly diminished. Thus, the flow of [5-12] supplies must continue to forward units as they are requested, including during NBC operations. For detailed information on providing health service logistics see FM 4-02.1 and FM 8-10-9.

#### 5-25. Protecting Supplies in Storage

Protecting supplies can be accomplished by placing them under tents, using plastic wraps, or providing storage warehouses with CB filtered-conditioned (heated or cooled) air systems. Wrapping supplies in two layers of plastic material provides protection from most agents for a short period of time; the thicker the plastic material, the longer the protection. Effectiveness of protective procedures can be checked by placing M9 tape on supplies and between layers of the covering. Protection from the thermal and blast effects of nuclear detonations requires much more elaborate measures. Placing the supplies in trenches, inside earthen berms, behind stonewalls, or in other field expedient facilities will enhance the protective posture of supplies from the nuclear effects. Even when taking these protective measures, a quantity of supplies will become contaminated and must be replaced. Plans should be in place for replacement of lost items.

#### 5-26. Protecting Supplies During Shipment

During shipment, supplies are protected by placement inside MILVANs, in covered enclosed vehicles, or by wrapping them in several layers of plastic, in tarpaulins, or in other protective material. To monitor exposure of supplies to chemical agents during shipment, place M9 detector paper between the wrappings. If exposure is limited to the outer layer, simple removal of this layer may be all that is required to eliminate the contamination. Decontamination is much easier when the supplies and equipment have been protected by multilayers of over-wraps.

#### 5-27. Organizational Maintenance

Maintenance on vehicles, equipment, and medical equipment will become much more complex under NBC conditions. Most chemical agents are soluble in organic solvents such as gasoline, motor oils, and lubricants. The agent may be removed from the equipment by these solvents, but exposure to the contaminated solvents will produce the same effects as exposure to the agent on the equipment. The agents may seep down around the threads of bolts, in cracks and crevices of the equipment, and inside the cabinets or enclosures of equipment. These potential contamination sources produce an increased hazard to maintenance personnel. Decontamination of some items, especially medical equipment, may be a problem for maintenance personnel. The use of standard decontamination agents will cause damage beyond repair to most medical equipment and electronic equipment. In some instances, removal of chemical agents will require aging (off-gassing) of the agent. Turning the equipment on and running it, or just exposing the equipment to warm air will speed the off-gassing process. Maintenance personnel must perform all procedures in MOPP Level 4 until decontamination is completed. Radiation will penetrate the metal structures of vehicles and other equipment; radioactive material will be absorbed into the lubricants and fuels. Decontamination of this type of contamination is very difficult, if not impossible. Personnel must use radiation detection equipment to determine the extent of contamination and decontaminate the items as much as possible. Dusting or washing with water can remove any fallout on the surface of vehicles and nonelectrical/electronic [5-13] components of equipment. Removal of radioactivity absorbed into metals or mixed in lubricants and fuels is beyond the capabilities of unit personnel. See FM 3-5 for decontamination procedures.

### Section VII. HOMELAND SECURITY RESPONSE

#### 5-28. Chemical, Biological, Radiological, Nuclear, and High-Yield Explosive Response

Although, homeland security is not a specific military mission, commanders must plan for and be prepared to support a lead federal agency (such as the Federal Bureau of Investigation or Federal Emergency Management Agency) in response to CBRNE event. When the CBRNE event occurs on a military installation, the Weapons of Mass Destruction—Incident Support Team (WMD-IST) is the lead federal agency in charge of responding and establishes an incident command center (ICC). The installation medical authority (IMA) provides the HSS initial response to the event site. Request for assistance from deployable HSS organizations and staffs are initiated by the IMA through military channels. The incident commander will submit a request for HSS assistance to a CBRNE event off the military installation through the appropriate federal channels. The President will direct any DOD response in support of a lead federal agency to a CBRNE event. The Presidential direction to assist will be passed down through military channels to the appropriate HSS organization for response. The HSS response may be in the form of special medical augmentation teams (SMART) support from US Army Medical Command resources or HSS (table of organization and equipment [TOE]) units may be directed to respond. Normally, responding TOE units will provide HSS to nonmedical military responders. However, the HSS mission may be to provide support to the lead federal agency or civilian public health organizations, emergency medical services (ambulance crews), or hospitals. The HSS response will include, but not be limited to—

- Providing medical care to casualties at the incident casualty decontamination site and supervising the casualty decontamination process to ensure that no further injury is caused to the casualty.
- Providing en route care for casualties from the incident site to an MTF or designated location for further care. Normally, TOE MEDEVAC assets are not used, but HSS personnel provide the en route care on locally provided transport vehicles.
- Providing guidance to local responders in the management of CBRNE casualties. The guidance may be on the correct use of antidotes, chemoprophylaxis, prevention of contamination spread in the MTF, patient decontamination at the MTF, and other related medical management procedures.
- Identifying suspect chemical, biological, or radiological materials used in the event.
- Providing guidance on application of standard precautions for CBRNE, especially preventive measures to prevent spread of contagious agents.
- Managing, triaging, and treating mass casualties.

## APPENDIX A
MEDICAL EFFECTS OF NUCLEAR, BIOLOGICAL, AND CHEMICAL WEAPONS AND TOXIC INDUSTRIAL MATERIAL

#### A-1. General

Biological and chemical weapons/agents may be employed by assassins, terrorists, rebels, and insurgents, as well as well-formed battle organizations, across the continuum of operations. In addition, nuclear weapons will remain a threat on the future battlefield. Another weapon that may be used is the RDD. The RDD can cause significant damage and present health hazards to fighting forces by exposing them to radiation without the thermal and full blast effects of nuclear weapons. The RDD can disperse radioactive material over an area of the battlefield; the area covered is dependent upon the amount of radioactive and explosive material used. In order to detonate a nuclear weapon, an adversary must first obtain access to the appropriate weapons-grade material. However, an RDD can be produced and used by anyone with access to industrial or medical radioisotopes and explosives. Biological agents are easy to disperse on the battlefield without immediate detection; however, their effects on exposed troops can change the course of the battle. Some nations consider chemical weapons as a component of their munitions for the battlefield. As more nations enter the arena of developing biological and chemical weapons, their potential effects on our troops will increase. The enemy's use of TIMs as weapons or collateral damage to TIM storage faculties can severely affect the unit personnel's ability to continue the mission. The signs and symptoms of some TIM exposure can be the same as those presented from exposure to NBC weapons. Considerations of both the physical and biological effects of these weapons are required for HSS operations. Field Manual 4-02.283 provides additional information on nuclear and radiological effects; FM 8-284 provides additional information on biological agent effects; FM 8-285 provides additional information on CW effects; FM 8-500 provides detailed information on hazardous material (TIM) effects.

#### A-2. Physical Effects of Nuclear Weapons

a. The principal physical effects of nuclear weapons are blast, thermal radiation (heat), and nuclear radiation. These effects are dependent upon the yield (or size) of the weapon expressed in kilotons (KT), the physical design of the weapon (such as conventional and enhanced), and the method of employment. The distribution of energy (Figure A-1) from the detonation of a moderate-sized (3 to 10 KT) weapon is as follows:

(1) Fifty percent as blast.

(2) Thirty-five percent as thermal radiation; made up of a wide spectrum of electromagnetic radiation, including infrared, visible, and ultraviolet light and some soft x-ray radiation.

(3) Fourteen percent as nuclear radiation, 4 percent as initial ionizing radiation composed of neutrons and gamma rays emitted within the first minute after detonation, and 10 percent as residual nuclear radiation (fallout).

(4) One percent as EMP.

b. Larger weapons are more destructive than smaller weapons, but the destructive effect is not linear. Table A-1 presents a comparison of three aspects of nuclear weapons effects with yield.

[A-2]

Figure A-1. Distribution of energy.

c. The altitude at which the weapon is detonated determines the blast, thermal, and nuclear radiation effects. Nuclear blasts are classified as air, surface, or subsurface bursts.

(1) An airburst is a detonation in air at an altitude below 30,000 meters, but high enough that the fireball does not touch the land or water surface. The altitude is varied to obtain the desired tactical effects. Initial radiation will be a significant hazard, but there is essentially no local fallout. However, the ground immediately below the airburst may have a small area of neutron-induced radioactivity. This may pose a hazard to troops passing through the area.

(2) A surface burst is a detonation in which the fireball actually touches and vaporizes the land or water surface. In this case, the area affected by blast, thermal radiation, and initial nuclear radiation will be smaller than for an airburst of comparable yield. However, in the region around ground zero, the [A-3] destruction will be much greater and a crater is often produced. Additionally, all the material that was within the fireball becomes fallout and will be a hazard downwind. A surface burst is the most likely type of terrorist detonation.

(3) A subsurface burst is an explosion in which the detonation is below the surface of land or water. Cratering usually results. If the burst does not penetrate the surface, the only hazard is from the ground or water shock. If the burst penetrates the surface, blast, thermal, and initial nuclear radiation will be present, though less than for a surface burst of comparable yield. Local fallout will be heavy over a small area.

(4) A high altitude burst occurs above 30,000 meters. Radiation and physical effects do not reach the ground and there is no local fallout. This is the only detonation where the effects of the EMP are significant. Nonhardened electronic equipment including many medical devices may become inoperative. The EMP damage is a moot point with other types of detonations, as its range is primarily limited to the area of intense physical destruction.

[A-4]

#### A-3. Physiological Effects of Nuclear Weapons

The physiological effects of nuclear weapons are the result of exposure to the blast; thermal radiation; ionizing radiation (initial or residual) effects; or a combination of these. For smaller weapons (less than 10 KT), ionizing radiation is the primary creator of casualties requiring medical care, while for larger weapons (greater than 10 KT), thermal radiation is the primary creator of casualties.

a. The rapid compression and decompression of blast waves on the human body results in transmission of pressure waves through the tissues. Resulting damage is primarily at junctions between tissues of different densities (bone and muscle), or at the interface between tissue and airspace. Lung tissue and the gastrointestinal system (both contain air) are particularly susceptible to injury. The tissue disruptions can lead to severe hemorrhage or to an air embolism; either can be rapidly fatal. Direct overpressure effects do not extend out as far from the point of detonation as the drag force and are often masked by the drag force effects. A typical range of probability of lethality, with variations in overpressure for a 1 KT weapon, is shown in Table A-2.

Table A-2. Range of Lethality of Peak Overpressure

LETHALITY (APPROXIMATE %) | PEAK OVERPRESSURE (ATMOSPHERES) | DISTANCE FROM GROUND ZERO; METERS
--- | --- | ---
1 | 2.3-2.9 | 150
50 | 2.9-4.1 | 123
100 | 4.1+ | 110

(1) The significance of the data is that the human body is relatively resistant to static overpressure compared to rigid structures such as buildings. For example, an unreinforced cinder block panel will shatter at 0.1 to 0.2 atmospheres.

(2) Overpressure lower than those in Table A-2 can cause nonlethal injuries such as lung damage and eardrum rupture. Lung damage is a relatively serious injury, usually requiring hospitalization, even if not fatal; whereas eardrum rupture is a minor injury, often requiring no treatment at all.

(a) The threshold level of overpressure for an unreinforced unreflected blast wave that can cause lung-damage is about 1.0 atmosphere.

(b) The threshold level for eardrum rupture is around 0.2 atmospheres; the overpressure associated with a 50 percent probability of eardrum rupture is about 1.1 atmospheres.

(3) Casualties requiring medical treatment from direct blast effects are produced by overpressure between 1.0 and 3.5 atmospheres. However, other effects (such as indirect blast injuries and thermal injuries) are so predominate that patients with only direct blast injuries make up a small part of the patient workload.

[A-5]

b. The drag forces (indirect blast) of the blast winds are proportional to the velocities and duration of the winds. The winds are relatively short in duration, but can reach velocities of several hundred km per hour. Injury can result from missiles impacting on the body or from the physical displacement of the body against objects and structures.

(1) The distance from the point of detonation at which severe indirect injury occurs is greater than that for equally serious direct blast injuries. A high probability of serious indirect injury can occur when the peak overpressure is about 0.2 atmospheres. This range will increase with the increased size of the weapon; for a 1 KT weapon, the range is 0.22 km, whereas for a 20 KT weapon, the range is 0.76 km. At greater ranges injuries will occur and casualties will be generated, but not consistently.

(2) The drag forces of the blast winds produced by a nuclear detonation are so great that almost any form of vegetation or structure will be broken up or fragmented into missiles. Thus, multiple, varied missile injuries will be common, increasing their overall severity and significance. Table A-3 lists ranges at which significant missile injuries can be expected.

1 | INCIDENCE OF INJURY BASED ON SKIN AND TISSUE PERFORATION.
2 | MISSILES USED WERE 10 GRAM (gm) IN WEIGHT.

(3) The velocity to which missiles are accelerated is the major factor in causing injury. The probability of a penetration injury increases with increasing velocity, particularly for small, sharp missiles such as glass fragments. Small, light objects are accelerated to speeds approaching the maximum (wind) velocity. Table A-4 shows data for probability of penetration related to size and velocity of glass fragments.

0.1 | 78 | 136 | 243
0.6 | 53 | 91 | 161
1.0 | 46 | 82 | 143
10.0 | 38 | 60 | 118

[A-6]

(4) Heavy, blunt missiles may not penetrate, but can result in significant injury, particularly fractures. The threshold velocity for skull fractures from a 4.5 milligram (mg) missile is about 4.6 meters per second (m/sec).

(5) The drag forces of the blast winds are strong enough to displace large objects (such as vehicles), or cause large structures to collapse (such as buildings) resulting in serious crushing injuries. Man himself can become a missile resulting in injuries (called translational injuries). The velocity at which the body is displaced will determine the probability and the severity of injury. Assuming a displacement of 3.0 meters, the impact velocity associated with various degrees of injury is shown in Table A-5. The velocities in Table A-5 can be correlated against yield. The ranges at which such velocities can occur and the probability of injury are given in Table A-6.

[A-7]

#### A-4. Biological Effects of Thermal Radiation

The thermal radiation emitted by a nuclear detonation causes burns in two ways—by direct absorption of the thermal energy through exposed surfaces (flash burns); or by the indirect action of fires in the environment (flame burns). Indirect flame burns can easily outnumber all other types of injury.

a. Thermal radiation travels outward from the fireball in a straight line; therefore, the amount of energy available to cause flash burns decreases rapidly with distance. Close to the fireball all objects will be incinerated. The range for 100 percent lethality will vary with yield, height of burst, weather, environment, and immediacy of treatment. The critical factors determining the degree of burn injury are the flux (calories per square centimeter/second [cal/cm2/sec]) and the duration of the thermal pulse. The total amount of thermal radiation needed to cause a flash partial thickness burn on exposed skin will vary with the yield of the weapon and the nature of the pulse (Table A-7). Most burn patients will come from the zones where partial thickness burns occur. In areas where radiation, blast, and thermal intensity are highest, burn victims surviving long enough to reach medical care will be rare.

NOTE

The battle dress uniform (BDU), MOPP gear, or any other clothing will provide additional protection against flash burns. The airspace between the clothing significantly impedes heat transfer and may prevent or reduce the severity of burns, depending on the magnitude of the thermal flux.

Table A-7. Factors for Determining the Probability of Partial Thickness Burns

YIELD OF WEAPON | 1 KT | 10 KT | 100 KT | 1 MT | 10 MT
--- | --- | --- | --- | --- | ---
RANGE (km) FOR PRODUCTION OF PARTIAL THICKNESS BURNS ON EXPOSED SKIN | 0.78 | 2.1 | 4.8 | 9.1 | 14.5
DURATION OF THERMAL PULSE IN SECONDS | 0.12 | 0.32 | 0.9 | 2.4 | 6.4
Cal/cm2/sec REQUIRED TO PRODUCE PARTIAL THICKNESS BURNS ON EXPOSED SKIN | 4.0 | 4.5 | 5.3 | 6.3 | 7.0

b. Indirect (flame) burns result from exposure to fires caused by the thermal effects in the environment, particularly from ignition of clothing. The larger-yield weapons are more likely to cause firestorms over extensive areas. There are too many variables in the environment to predict either incidence or severity of casualties. Expect the burns to be far less uniform (in degree) and not limited to exposed [A-8] surfaces. For example, the respiratory system may be exposed to the effects of hot gases produced by extensive fires. Respiratory system burns cause high morbidity and high mortality rates.

c. The initial pulse of radiation in the optical and thermal bands can cause injuries in the forms of flash blindness and retinal scarring. The initial brilliant flash of light produced by the nuclear detonation causes flash blindness. This flash swamps the retina, bleaching out the visual pigments and producing temporary blindness. During daylight hours, this temporary effect may last for about 2 minutes. At night, with the pupil dilated for dark adaptation, flash blindness will affect personnel at greater ranges and for greater durations. Partial recovery can be expected in 3 to 10 minutes, though it may require 15 to 35 minutes for full night adaptation recovery. Retinal scarring is the permanent damage from a retinal burn. It will occur only when the fireball is actually in the individual's field of view and should be a relatively uncommon injury. The location of the scar will determine the degree of interference with vision. Because night vision apparatus electronically amplifies an image, it cannot transmit the flash intensity and will not cause eye injury.

#### A-5. Physiological Effects of Ionizing Radiation

A nuclear burst results in four types of ionizing radiation: neutrons, gamma rays, beta, and alpha radiation. The initial burst is characterized by neutrons and gamma rays while the residual radiation is primarily alpha, beta, and gamma rays. The effect of radiation on a living organism varies greatly by the type of radiation to which the organism is exposed. See Table A-8 for characteristics of nuclear radiation.

a. Alpha particles are extremely massive, charged particles (four times the mass of a neutron); they are a fallout hazard. Because of their size, alpha particles cannot travel far and are fully stopped by the dead layers of the skin or by the uniform. Alpha particles are a negligible external hazard, but if inhaled or ingested, can cause significant internal damage.

Figure A-2. Threshold distance for minimal chorioretinal burn and flash blindness versus yield (airburst) at night.

[A-9]

NAME AND SYMBOL | WHAT IS IT | SOURCE | ENERGY AND SPEED | RANGE IN AIR | RANGE IN TISSUE | SHIELDING REQUIRED | BIOLOGICAL HAZARD
α ALPHA PARTICLE | HELIUM NUCLEUS | DECAY OF URANIUM AND PLUTONIUM | ENERGY VARIES: SPEED VARIES FROM 1/20 TO 1/10 SPEED OF LIGHT | ~ 5 cm | CANNOT PENETRATE THE EPIDERMIS | NONE | NONE, UNLESS INGESTED OR INHALED IN SUFFICIENT QUANTITIES
β BETA PARTICLE | HIGH-SPEED SPEED ELECTRON | DECAY OF FISSION PRODUCTS AND NEUTRON INDUCED ELEMENTS | VARIES OF SKIN | 5 METERS OR MODERATE | SEVERAL LAYERS SKIN INJURY | STOPPED BY A FEW cm OF Al CLOTHING | SUPERFICIAL
γ GAMMA RAY | ELECTRO-MAGNETIC ENERGY | DECAY OF FISSION PRODUCTS AND NEUTRON INDUCED ELEMENTS | ENERGY VARIES: TRAVELS AT THE SPEED OF LIGHT | UP TO 500 METERS, BUT IS ENERGY DEPENDENT | VERY PENETRATING, BUT IS ENERGY DEPENDENT | DENSE MATERIAL, SUCH AS CONCRETE, STEEL PLATE, EARTH | WHOLE BODY INJURY, MANY CASUALTIES POSSIBLE
η NEUTRON | UNCHARGED PARTICLE | FISSION AND FUSION REACTIONS | VARIES | LESS THAN GAMMA, BUT IS ENERGY DEPENDENT | VERY PENETRATING, BUT IS ENERGY DEPENDENT | HYDROGENOUS MATERIALS, SUCH AS WATER OR DAMP EARTH | WHOLE BODY INJURY, MANY CASUALTIES POSSIBLE

b. Beta particles are very light, charged particles that are found primarily in fallout radiation. These particles can travel a short distance in tissue; if large quantities are involved, they can produce damage to the basal stratum of the skin. The lesion produced is similar to a thermal burn (called a beta burn).

c. Gamma rays, emitted during the nuclear detonation and in fallout, are uncharged radiation similar to X rays. They are highly energetic and pass through matter easily. Because of its high penetrability, radiation can be distributed throughout the body, resulting in whole body exposure.

d. Neutrons, like gamma rays, are uncharged, are only emitted during the nuclear detonation, and are not a fallout hazard. However, neutrons have significant mass and interact with the nuclei of atoms, severely disrupting atomic structures. Compared to gamma rays, they can cause 20 times more damage to tissue.

e. When radiation interacts with atoms, energy is deposited resulting in ionization (electron excitation). This ionization may involve certain critical molecules or structures in a cell, producing its characteristic damage. Two modes of action in the cell are direct and indirect action. The radiation may directly hit a particularly sensitive atom or molecule in the cell. The damage from this is irreparable; the cell either dies or is caused to malfunction. The radiation can also damage a cell indirectly by interacting with water molecules in the body. The energy deposited in the water leads to the creation of toxic molecules; the damage is transferred to and affects sensitive molecules through this toxicity.

[A-10]

f. The most radiosensitive organ systems in the body are the male reproductive, the hematopoietic, and the gastrointestinal systems. The relative sensitivity of an organ to direct radiation injury depends upon its component tissue sensitivities. Cellular effects of radiation, whether due to direct or indirect damage, are basically the same for the different kinds and doses of radiation. The simplest effect is cell death. With this effect, the cell is no longer present to reproduce and perform its primary function. Changes in cellular function can occur at lower radiation doses than those that cause cell death. Changes can include delays in phases of the mitotic cycle, disrupted cell growth, permeability changes, and changes in motility. In general, actively dividing cells are most sensitive to radiation. Additionally, radiosensitivity tends to vary inversely with the degree of differentiation of the cell.

g. Predicting radiation effects is difficult because often it is unknown which organs were exposed. Thus, most predictions are based on whole body irradiation. Partial body and specific organ irradiation will occur due to shielding by equipment, from fallout particles, or from internal deposition. Depending upon the organ system, the irradiation can be severe. The severe radiation sickness resulting from external, whole body irradiation and its consequent organ effects is a primary medical concern. The median lethal dose (LD) of radiation that will kill 50 percent of the exposed persons within a period of 60 days (designated as LD50/60) is estimated to be approximately 4.5 gray (Gy) if appropriate medical care is not provided to the casualties. Medical intervention should raise this figure to approximately 10 Gy. This larger figure includes most of the casualties who would be actually capable of reaching medical care following a nuclear detonation, and nearly all those who could be exposed to a RDD. For acute effects of single high dose rate exposures of whole-body irradiation to healthy adults see Table A-9.

h. Recovery of a particular cell system will occur if a sufficient fraction of a given stem cell population remains after radiation injury and appropriate stimulation and protection are received. Complete recovery may appear to occur; however, the immune system may repair incompletely with consequent greater susceptibility to future insult from a variety of agents. It is possible for late somatic effects to have a higher probability of occurring because of the radiation damage. Efficacy of both prior and future immunization in this group is not adequately understood.

i. Interactions between radiological injury and chemical or biological agents appear to be synergistic. Insult by these agents in radiologically injured personnel, even in individually subclinical dosages, may result in significant clinical illness.

#### A-6. Handling and Managing Radiologically Contaminated Patients

a. Radiologically Contaminated Patients. Personnel from contaminated areas may have fallout on their skin and clothing. Although the individual will not be radioactive, he may suffer radiation injury from the contamination. Removal of the contamination should be accomplished as soon as possible; definitely before admission into a clean treatment area. The distinction must be made between a radiation-injured soldier and one who is radiologically contaminated. Although personnel may have received substantial radiation exposure, this exposure alone does not result in the individual being contaminated. Contaminated personnel do not pose a short-term hazard to the medical staff, rather the contamination is a hazard to the individuals' health. However, without patient decontamination, medical personnel may receive sufficient exposure to create beta burns, especially with extended exposure.

[A-11]

b. Handling Radiologically Contaminated Patients. To properly handle radiologically contaminated personnel, medical personnel must first detect the contamination. Detectors that may be used are the AN/PDR27 and AN/VDR2 to monitor patients for contamination. Generally, a reading on the meter twice the current background reading indicates that the patient is contaminated. Monitoring is conducted when potentially contaminated personnel arrive at the MTF. This monitoring is conducted at the MTF's receiving point before admitting the patient. Contaminated patients must be decontaminated before admission. Removal of radiological contamination is less important than immediate lifesaving treatment and providing the best possible medical care. Lifesaving care before decontamination is provided outside the MTF.

c. Decontamination. Removing all outer clothing and a brief washing or brushing of exposed skin will reduce 95 percent of contamination; vigorous bathing or showering is unnecessary. See Appendix G for patient decontamination procedures.

d. Internal Contamination. Internalization of radioactive isotopes will primarily occur via inhalation, ingestion, and contaminated wounds. Extensive internal decontamination should only be undertaken when individual dose estimates indicate that the individual will benefit from the procedures. Soldiers who wear their protective mask will be adequately protected from inhalation and ingestion of radioactive particulate matter. Internal contamination is considered a delayed problem and does not influence triage categories, as does irradiation injury.

e. Treatment. Treatment procedures for radiation injuries are described in FM 4-02.283, FM 8-9, and the NATO Handbook, Emergency War Surgery. Appropriate medical intervention and bone marrow resuscitation will prevent most deaths secondary to irradiation and infection.

#### A-7. Radiological Patients in Stability Operations and Support Operations

In stability operations and support operations, high levels of environmental contamination and the use of RDD can cause radiological injury to personnel at levels below that necessary to produce performance decrement and traditional casualty status. Treatment and evacuation guidelines will be in accordance with command guidance. Individual physical dosimetry is the most expedient measurement technique for this exposure (see Table A-10). These radiation injuries and effects may also be seen in war; especially, from hostile forces employment of RDDs.

#### A-8. Effects of Biological Weapons

Biological warfare is the intentional use, by an enemy, of live agents or toxins to cause death and disease among personnel, animals, and plants, or to deteriorate materiel.

a. Live Agents.

(1) Live agents are living organisms like viruses, bacteria, and fungi. They can be delivered directly (artillery or aircraft spray), or through a vector such as a flea or tick. Advances in modern weaponizing of biological agents have become easier.

(2) For some agents, only a few organisms are needed to cause infection. Live agents are small and light; they can be spread great distances by the wind and contaminate unfiltered or nonairtight places.

(3) Aerosolized particles of 1 to 5 micron (μ) size carrying live agents are small and light. They require time after they are ingested to multiply enough to overcome the body's defenses. This incubation period may vary from hours to days or weeks depending on the type of organism. Thus, to be effective, a live agent attack would need to be launched well in advance of a tactical assault.

(4) These agents are sensitive to environmental conditions (for example humidity and sunlight). Many bacterial agents will not survive outside the host organism (human and animals).

(5) Live agents are not detectable by any of the five physical senses; usually the first indication of a biological attack is the ill personnel. The diseases caused by live agents may be difficult to control when the aerosol attack is directed against a large population. Some diseases may be transmitted from person-to-person after the initial attack; examples include plague, smallpox, and some viral hemorrhagic fevers.

(6) Because of their incubation period and life cycle, likely areas for live agent use are in the combat service support (CSS) area; but attacks in forward areas cannot be ruled out.

b. Spore Forming Biological Agents. Spore formers such as anthrax can survive for an extended time, even under very adverse environmental conditions (dry, extremes of temperatures, and flooding). Once inhaled, ingested, or injected into the human body, the spores germinate and produce the illness.

c. Toxins.

(1) Toxins are by-products (poisons) produced by plants, animals, or microorganisms. It is the poisons that harm man, not the organisms that make the toxins. In the past, the only way to deliver toxins on a large scale was by using the organism. With today's technology large quantities of many toxins can be produced; thus, they can be delivered without the accompanying organism.

(2) Toxins have several desirable traits. They are poisonous compounds that do not grow, reproduce, or die after they have been dispersed; they are more easily controlled than live organisms. Field [A-15] monitors capable of providing prompt warning of a toxin attack are not available; therefore, personnel must learn to quickly recognize signs of attack, such as observing unexplained symptoms of victims. Toxins produce effects similar to those caused by chemical agents; however, the victims will not respond to the first-aid measures that work against chemical agents. Unlike live agents, mycotoxins (T2) can penetrate intact skin; other toxins cannot. Because the effects on the body are direct, the symptoms of an attack may appear very rapidly. The potency of most toxins is such that very small doses will cause injuries and/or death. Thus, their use by an enemy may be an alternative to chemical agents because it allows the use of fewer resources to cover the same or a larger area. Slight exposure at the edges of an attack area may produce severe symptoms or death from exposure to toxins because of their extreme toxicity. Lethal or injury downwind hazard zones for toxins may be far greater than those of CW agents.

#### A-9. Behavior of Biological Weapons

Biological agents can be disseminated in a spectrum of physical states. They may be living microorganisms or spore forms of the organism. See Table A-11 for stability of various biological agents. They may be spread by—

- Arthropods.
- Contact with infected animals.
- Contamination of food and water.
- Aerosol, liquid, or solid dispersion.

The only requirement is that they must be stable enough to survive transport and dissemination. The toxicity of biological agents is not the same for everyone; each individual does not react exactly the same way to the same amount of an agent. Some are more resistive than others because of race, sex, age, or other factors. The dose is the quantity of a biological agent received by the subject. The penetration of agents by various routes need not be accompanied by irritation or damage to the absorbent surface. There are often unique signs and identifying symptoms depending on entry route (inhalation, ingestion, or dermal).

a. Biological agents dispersed by spray often enter the body through the respiratory tract (inhalation injury). The agent may be absorbed by any part of the respiratory tract from the mucosa of the nose and mouth to the alveoli of the lungs.

b. Liquid droplets and (less commonly) solids may be absorbed from the surface of the skin, digestive tract, and mucous membranes. Agents penetrating the skin may form temporary reservoirs under the skin.

c. Contaminated food and water can produce casualties when ingested.

#### A-10. Management of Biological Warfare Patients

a. Management. Management of patients suffering from the effects of BW agents may include the need for isolation. Barrier nursing for patients suspected of suffering from exposure to BW agents will reduce the possibility of spreading the disease to health care providers and other patients. Specimens must be collected and submitted to the designated supporting laboratory for identification. For details on hospital infection control aspects of managing BW casualties, see FM 8-284.

b. Mass Casualty. A BW agent attack can produce a mass casualty situation at all levels of HSS. A major problem with a BW mass casualty situation is that HSS personnel are more susceptible to becoming a casualty to BW agents. Also, the ill patient may be the first indicator that a BW agent has been dispersed.

c. Decontamination. Decontamination is an individual and unit responsibility. However, some individuals may arrive at the MTF that have not been decontaminated or that become contaminated en route [A-17] to the MTF. These individuals must be decontaminated at the MTF before they are admitted to prevent contamination of the MTF and exposure of medical personnel to the biological agent. See Appendix G for details on patient decontamination.

d. Treatment. Specific treatment is dependent upon the BW agent used. Patients are treated for symptomatic presentation unless the BW agent identity is known. Field Manuals 8-9 and 8-284 provide detailed information on medical management and treatment.

#### A-11. Effects of Chemical Weapons

a. A chemical agent is a chemical that is used to kill, seriously injure, or incapacitate man because of its physiological effects. They can be disseminated by artillery, aircraft, rocket, or by nonconventional means used by terrorists. When first employed in combat during World War I, the chemical weapon (chlorine) was so effective that the attacking Germans were not prepared to exploit the success.

b. Chemical agents are very effective weapons against poorly trained and equipped forces; however, they are less effective against well-trained forces.

#### A-12. Behavior of Chemical Weapons

Chemical agents can be disseminated as a gas, vapor, or aerosol under ambient conditions. They have a range of odors varying from none to highly pungent characteristics. Their stability is dependent upon the environmental conditions in the area of employment. See Table A-11 for persistency of various chemical agents.

a. The toxicity of a chemical agent is not the same for everyone; each individual does not react exactly the same way to the same amount of an agent. Some are more resistant than others because of physiological factors. The dose is the quantity of a chemical received by the individual for percutaneous or oral doses and as a time-weighted concentration, milligrams-minute (m3), for inhalation. It is usually expressed as milligrams of agent per kilogram of subject body weight (mg/kg). The LD50 is the dose that kills 50 percent of the exposed population. The incapacitation dose 50 (ID50) is the incapacitation dose for 50 percent of the exposed subjects. The penetration of agents by various routes need not be accompanied by irritation or delayed superficial damage to the absorbent surface, but there are often unique signs and symptoms identifiable by the route of entry.

(1) Gaseous, vapor, and aerosol chemical agents often enter the body through the respiratory tract (inhalation injury). The agent may be absorbed by any part of the respiratory tract from the mucosa of the nose and mouth to the alveoli of the lungs. Aerosol particles larger than 5 μ tend to be retained in the upper respiratory tract; particles in the 1 to 5 μ range are retained in the deep volume of the lungs; while those below 1 μ tend to be breathed in and out again; although a few are retained in the deep volume of the lungs.

(2) Vapors and droplets of liquids can be absorbed from the surface of the skin and mucous membranes. Toxic compounds that are harmful to the skin can produce their effects in liquid or solid state. Agents penetrating the skin may form temporary reservoirs under the skin; the vapors of some volatile [A-18] liquids can penetrate the skin and cause intoxication. Additionally, wounds and abrasions may present areas that are more permeable than intact skin.

b. Chemical agents may be divided into two main categories (persistent and nonpersistent) that describe how long they are capable of producing casualties. Table A-12 lists the common chemical agents, their effects and time of effectiveness. Table A-13 lists the types and characteristics of common chemical agents.

(1) Persistent agents continue to present a hazard for considerable periods (days) after delivery by remaining as a contact hazard, or by slowly vaporizing to produce a hazard by inhalation.

(2) Nonpersistent agents disperse rapidly after release and present an immediate, short duration (hours) hazard. They are released as airborne particles, aerosols, and gases.

#### A-13. Characteristics of Chemical Agents

The effectiveness of a chemical agent is a measure of how much agent is required to produce the desired effect. Thus, an agent that is toxic at a lower dose than another similar agent is more effective. Besides dose required for a given effect, persistency may be used to measure effectiveness. Persistency depends on the agent's physical characteristics, the amount of agent delivered, its physical state, weapons system used, the terrain, and weather in the target area. The desired effects will determine the physical, chemical, and toxicological properties of the chemical agent employed.

a. Nerve agents are primarily organophosphorus esters similar to insecticides. Those of military importance are combined under this term. Although some have been given names, they are usually known by their code letters: GA; GB; GD; and VX. They are all liquids, varying in volatility that is in a range between gasoline and heavy lubricating oil. Their freezing points are -40 degrees Celsius or lower.

(1) Liquid nerve agents are pale yellow to colorless and are almost odorless. They are moderately soluble in water and highly soluble in lipids (oil). They are rapidly destroyed by strong alkalies and chlorinating compounds. Normal clothing is readily penetrated by liquid or vapor agents. Butyl rubber and synthetic material are more resistant than natural fibers. Agents can penetrate into nonabsorbent material such as web belts and can continue to present a hazard by desorption (off-gassing) of the vapor. Although local sweating and twitching may occur, usually there is no local irritant change after cutaneous exposure. Toxicity depends upon the route of entry and physical characteristics.

(2) Nerve agents strongly inhibit the cholinesterase enzymes. When acetylcholine is released by the nerve junction, it is hydrolyzed by the enzyme. Acetylcholine is the chemical mediator for transmission of the nerve impulses in numerous synapses of the central nervous system (CNS) and the autonomic nervous system and at the endings of the cholinergic nerves (for example: affecting the smooth muscles of the iris, ciliary, bronchial tree, and gastrointestinal tract). The inhibition of cholinesterase by nerve agents is almost irreversible, so the effects are prolonged. Until the cholinesterase level is restored to normal, there is an increased susceptibility to nerve agent exposure. During this time, the effects of [A-20] repeated exposure are cumulative and the patient may feel "subpar" (for example: tired, fatigue easily, poor appetite, impaired concentration) until recovery is complete.

(3) Nerve agent poisoning is easily identified by the characteristic signs and symptoms as follows:

(a) MILD symptoms (self-aid). Casualties with MILD symptoms may experience most or all of the following:

- Unexplained runny nose.
- Unexplained sudden headache.
- Sudden drooling.
- Difficulty in seeing (dimness of vision) (miosis).
- Tightness in the chest or difficulty in breathing.
- Localized sweating and muscular twitching in the contaminated area.
- Stomach cramps.
- Nausea.

(b) Casualties with MODERATE symptoms (buddy aid) will experience an increase in the severity of most or all of the MILD symptoms. Especially prominent will be an increase in fatigue, weakness, and muscle fasciculations. The progress of symptoms from MILD to MODERATE indicates either inadequate atropine treatment or continuing exposure to agent.

(c) SEVERE symptoms (buddy aid). Casualties with SEVERE symptoms may experience most or all of the MILD symptoms, plus most or all of the following:

- Strange or confused behavior.
- Wheezing, dyspnea (severe difficulty in breathing), and coughing.
- Severely pinpointed pupils.
- Red eyes with tearing.
- Vomiting.
- Severe muscular twitching and general weakness.
- Involuntary urination and defecation.
- Convulsions.[A-21]
- Unconsciousness.
- Respiratory failure.

b. There are three major families of blister agents (vesicants); HD and HN, L, and CX. Most vesicants (except CX) are relatively persistent. Mustards can modify the structure of nucleic acids, cellular membranes, and proteins by combining with certain functional groups (particularly the sulfhydryl-containing enzymes) for which they have an affinity.

(1) The cutaneous syndrome is divided into four phases: latent, erythema, vesication, and necrosis. Vesicants can penetrate the skin by contact with either liquid or vapor. The latent period is characteristic of the agent. For mustards it is usually several hours, for L it is short, and for CX it is negligible. The latent period is also affected by the dose, temperature, and humidity. The symptoms of the erythema phase are red, painful itching followed by painful necrosis that heals slowly.

(2) In the eyes, vesicants produce intense pain and photophobia. Blistering of the eyelids and mucous membranes can result in temporary blindness. Even after recovery, scars on the cornea can reduce visual acuity.

(3) In the respiratory tract, these agents attack the mucous membranes irritating them. They can paralyze vocal chords and can lead to chemical pneumonitis, or possibly death.

(4) Although blister agents can affect other organs and produce deleterious effects, the skin, eyes, and respiratory tract are the principle organs effected.

c. Chemical agents that attack lung tissue (choking agents) and cause pulmonary edema are classed as lung damaging agents. Choking agents consist of CG and DP, CL, and PS. Phosgene is typical of the lung-damaging agents; it is used as the example here.

(1) Phosgene is a colorless gas that has an odor resembling new mown hay. Although effects are primarily confined to the lungs, phosgene may also cause mild irritation of the eyes and upper respiratory tract. Phosgene causes a shift in the membrane potential of the alveoli allowing the passage of fluid into the alveoli, resulting in massive pulmonary edema and severely impairing the exchange of oxygen (O2) and carbon dioxide (CO2) between the capillary blood and the alveolar air.

(2) Initially hypoxemia occurs and is followed shortly by hyperventilation when the frothy edema fluid fills the bronchioli and CO2 expiration stops.

(3) Signs and symptoms during and immediately following exposure are coughing, tightness of chest, nausea, occasionally vomiting, headache, and lacrimation (tearing).

d. Blood agents consist of AC and CK; both are readily absorbed by the mucous membranes and the intact skin. The odor of AC resembles bitter almonds, but many people cannot detect it. Detecting the [A-22] odor of CK is difficult because of its irritating and lacrimatory effects. It is also poorly absorbed by the metallic salt-impregnated charcoal filters in the protective mask. These agents inhibit certain enzymes (particularly cytochrome oxidase) that are important for oxidation-reduction in the cells; therefore, cell respiration is inhibited and oxygen carried by the hemoglobin is not consumed causing the venous blood to remain bright red. Initial symptoms are characterized by violent convulsions, increased deep respiratory movements, followed by cessation of respiration within one minute, slowing of heart rate to death. High concentrations exert their effects rapidly; however, if the patient is still alive after the cloud has passed, he will probably recover spontaneously.

e. Incapacitating agents are chemicals that produce a temporary disabling condition that persists for hours to days after exposure to the agent has ceased (unlike that produced by riot control agents). While not required, medical treatment produces a more rapid recovery. Characteristics of these agents are that they—

- Are highly potent and logistically feasible.
- Produce their effects mainly by altering or disrupting the higher regulatory activity of the CNS.
- Produce effects that last for hours or days rather than momentary or fleeting.
- Do not seriously endanger life, except in exceedingly high doses.
- Produce no permanent injury.

The two types likely to be encountered are CNS depressants and CNS stimulants.

(1) Central nervous system depressants are compounds that have a predominant effect of depressing or blocking the activity of the CNS; often by interfering with the transmission of information across synapses. An example of this type of agent is BZ. The action of acetylcholine, both peripherally and centrally, appears to be blocked by BZ. Low doses disrupt higher integrative functions of memory, problem solving, attention, and comprehension. High doses produce toxic delirium that destroys the ability to perform any military task. Within the CNS, BZ seems to produce its effects in the same way as atropine. Small doses cause sleepiness and decreased alertness with elevated heart rate, dry skin and eyelids, drowsiness, increased pupil size, and elevated skin temperatures. Progressive intoxication is marked by an inability to respond effectively to the environment (4 to 12 hours), followed by increasing activity and random/unpredictable behavior (12 to 96 hours). Because the patient cannot sweat, heat stress becomes a problem.

(2) Central nervous system stimulants are agents that cause excessive nervous activity, often by boosting or facilitating transmission of impulses across synapses. The effect is to "flood" the cortex and other higher regulatory centers with too much information, making concentration difficult and causing indecisiveness and an inability to act. These include LSD, psilocybin, and mescaline. Intoxication shows sympathetic stimulation (rapid heart rate, sweaty palms, pupillar enlargement, and cold extremities) and mental excitation (nervousness, trembling, anxiety, and inability to relax or sleep); feelings of tension, exhilaration, heightened awareness, paranoid ideas, and profound states of terror may also occur.

[A-23]

#### A-14. Management of Chemical Agent Patients

a. Management. Movement of chemical agent casualties can spread the contamination to clean areas. All casualties are decontaminated as far forward as the situation permits. All patients must be decontaminated before they are admitted into a clean MTF. The admission of one contaminated patient into an MTF will contaminate the facility; thereby reducing its treatment capabilities.

b. Mass Casualty. A mass casualty situation is presented when chemical agents are employed. Additional HSS personnel and equipment must be provided in a short period of time if the level of care is to be maintained. Treatment at far forward MTFs is limited to life- or limb-saving care. Patients that can survive evacuation to the next level of care are not treated at the forward facility. This provides time for treating those patients that cannot survive the evacuation time.

c. Decontamination. Decontamination is an individual and unit responsibility. However, some individuals may arrive at the MTF that have not been decontaminated or that become contaminated en route to the MTF. These individuals must be decontaminated at the MTF before they are admitted to prevent contamination of the MTF and exposure of medical personnel to the chemical. See Appendix G for detailed information on patient decontamination procedures.

d. Treatment. Field Manuals 8-9 and 8-285 provide treatment procedures for chemical agent patients.

#### A-15. Management of Toxic Industrial Material Patients

a. Management. Movement of TIM casualties can spread the contamination to clean areas. All casualties are decontaminated as close to the incident site as possible. All patients must be decontaminated before they are admitted into a clean MTF. The admission of one contaminated patient into an MTF may contaminate the facility; thereby reducing its treatment capabilities.

b. Mass Casualty. A mass casualty situation is presented when the number of casualties exceeds the capabilities of medical personnel at the location to provide needed care at the incident site. Treatment at the incident site is limited to life- or limb-saving care. Patients that can survive are evacuated to the nearest MTF with a patient decontamination capability.

c. Decontamination. Decontamination is an individual and first responder responsibility. However, some individuals that self evacuated or were evacuated due to the mass casualty situation arrive at the MTF that have not been decontaminated. These individuals must be decontaminated at the MTF before they are admitted to prevent contamination of the MTF and exposure of unprotected medical personnel and other patients to the TIM. See FM 8-500 for detailed information on decontamination procedures for TIM contaminated casualties.

d. Treatment. Field Manual 8-500 provides treatment procedures for some TIM casualties. Treatment for many TIM casualties is agent specific and receiving MTFs must be prepared for these events.

[A-24]

EXAMPLE: Treatment for a casualty exposed to toxic levels of an inorganic phosphate pesticide would be treated in the same manner as a nerve agent casualty except the amount of antidote for the pesticide poisoned casualty will be many times greater than for the nerve agent casualty.

## APPENDIX B
SAMPLE/SPECIMEN COLLECTION AND MANAGEMENT

### Section I. INTRODUCTION

#### B-1. General

a. Critical elements for accuracy in analysis of NBC samples and physiological specimens are correct collecting, packaging, handling, and transporting techniques. The quality of any analytical evaluation is directly related to the quality of the sample/specimen and the degree of postcollection degradation that occurs prior to testing. Health service support personnel collect and submit specimens for suspect NBC hazards/agents involving humans and animals. Chemical corps and other nonmedical units collect and submit environmental (air, plant, and soil) samples for suspect NBC hazards/agents. Preventive medicine personnel collect and submit water and ice samples for suspect NBC hazards/agents. Veterinary personnel collect and submit food samples, such as fruits and vegetables, and specimens from animals for suspect NBC hazards/agents. Specimens collected from patients that are suspect of being exposed to a biological agent are forwarded to the supporting medical laboratory (such as the TAML, AML or US Navy Forward Deployed PVNTMED Unit) for analysis.

b. Essentially all military operations from war to stability operations and support operations may generate medical laboratory testing requirements. Each scenario, geographical region, population base, and suspect agent will impact on the type and amount of samples/specimens required and the collection process. During all operations, express permission is required before collecting specimens from civilians because of religious or sociological beliefs in many cultures. To obtain such specimens without permission could result in unnecessary mission complications.

NOTES

1. The term "sample" refers to nonhuman and nonanimal origin. The term "specimen" refers to human and animal origin.
2. Always consider that chemical agents may have been employed. Check for chemical agents before collecting a biological sample/specimen. Chemical agents can damage or destroy biological agents. Also, chemical agents not identified in the sample/specimen can pose a hazard to receiving laboratory personnel. Mark all samples that are potentially contaminated with chemical agents as such.
3. Precautions should be taken to protect the sample/specimen collector from potential BW agents; at a minimum, respiratory protection and rubber gloves must be worn. Additional care must be taken when collecting samples/specimens to prevent cross-contamination. Gloves must be changed or decontaminated between sample/specimen collections.
[B-2] 4. Samples will not be delivered to the clinical laboratory of an MTF for analysis. They must be delivered to the designated supporting medical laboratory for processing. This will prevent accidentally spreading a biological agent in the MTF.

c. Coordination for follow-on testing is absolutely critical to the sample/specimen collection process.

d. Coordination with the receiving laboratory should be made to establish sample requirements, preferred collection techniques, methods of preservation, and transportation conditions, when the tactical situation and/or mission permits.

e. The number of medical specimens that need to be collected varies with the type of analysis performed and the impact of the values determined. The number and types of "control" samples/specimens required to validate test information is determined by the supporting medical laboratory personnel. Random sampling, matched with control populations, or other techniques will be employed as the requirements are identified.

#### B-2. Sample/Specimen Background Information

a. A complete history of the circumstances about each sample's/specimen's acquisition must be provided to the agency conducting the analysis.

b. Critical information includes, but is not limited to—

- Meteorological conditions. Describe what the meteorological conditions were at the time of the alleged attack and at the time of the sampling.
- Attack to collection time. State the length of time after alleged attack when sample/specimen was taken.
- Circumstances of acquisition. Describe how the sample/specimen was obtained and the source of the sample/specimen.
- Physical description. Describe the physical state of the sample/specimen (solid, liquid, powder, apparent viscosity), color, approximate size, identity of the sample/specimen (that is, dirt, leaves, blood, tissue), and dose rate (if radiologically contaminated).
- Circumstances of the agent deposition. Describe the type of delivery system, a description of how the weapon functioned, how the agent acted on release, sounds heard during dissemination, a description of any craters or shrapnel found associated with the burst, and colors of smoke, flames, or mists that may be associated with the attack.
- [B-3] Agent effects on vegetation. Describe the general area (jungle, mountain, grassland) and changes in the vegetation after the agent deposition (that is, color change, wilting, drying, dead) in the main attack and fringe areas.
- Agent effects on humans. How the agent affected personnel in the main attack area versus fringe areas; the duration of agent effects; peculiar odors that may have been noticed in the area before, during, or after an attack; measures taken that alleviated or worsened the effects; and the approximate number of victims and survivors (include age and gender).
- Agent effects on animals. Describe how they are affected.
- Grid coordinates or other descriptive information on sample collection location.

#### B-3. Sample/Specimen Collection and Preservation

a. Ante mortem Specimens. Physiological specimens from living human or animal patients can include just about any conceivable body source or excreted by-product. It must be noted that specimen types are seldom interchangeable; the exact type and amount of specimen required for a specific assay must be known before a collection procedure is initiated (see Table B-1).

- Patients seen in an MTF may be the first and in some cases the only source for sampling for suspect biological agent release. The primary medical care provider will determine the level of treatment for these patients and the specimens required for laboratory diagnosis. The MTF laboratory is not equipped to handle biological agents and, therefore, specimens generated will be forwarded to the supporting medical laboratory for analysis. Patient disposition will be based on evacuation policies, exposure, suspect agent, clinical symptoms, and required treatment/isolation.
- Blood specimens represent the most common analytical sample. Certain techniques and special care must be exercised to ensure an acceptable specimen is collected and to minimize an adverse affect to the patient or specimen collector. In general, phlebotomy requires the use of a 20 to 22-gauge needle to minimize mechanical hemolysis during aspiration using a syringe or VacutainerTM tube collection system. Blood collected with a syringe and needle should be transferred to an appropriate VacutainerTM tube immediately after collection. The type of tube, type of anticoagulant or preservative, and amount of blood collected will vary with the specific assay requested. Unless some special sample preparation step is required, the blood is best left in the original rubber-stopper tube for transport.
- Urine specimens are best collected using a clean-catch (midstream, if possible) technique in a sterile urine cup. The volume of sample required will vary depending on the specific assay requested; however, 25 to 50 ml is sufficient for most tests.
- Tissue specimens can originate from any body source accessible by scraping, swabbing, or minor excision. Tissue specimens are collected only by medical trained personnel. Specific techniques for collecting these specimens are not provided in this appendix.
- [B-4] Sputum specimens are best collected using a sterile cup. The volume of specimen will normally be very small. However, a sufficient quantity must be collected to provide for in-theater testing and to provide for CONUS laboratory testing.
- Nasal swabs should be collected using sterile cotton-tipped swabs. The swabs with specimen from each person should be placed in a separate sterile container to prevent cross-contamination.

NOTE

In cases where the supporting laboratory cannot be contacted, as a minimum the following specimens should be collected: Urine—25 to 50 ml in a sterile container. Blood—two 7 to 10 ml tubes without anticoagulant (red-stopper VacutainerTM); two 7 to 10 ml tubes with potassium or sodium ethylenediaminetetraacetate (EDTA) (lavender-stopper VacutainerTM).

- All specimens (regardless of physiological source) must be labeled to positively identify the individual or animal from whom it was collected; at a minimum, the individual's full name, unique personal identification number (social security number, when possible), military unit and location, and date and time of collection should be written on the label of the specimen container.
- All specimens are collected using aseptic techniques. All specimens are packaged, handled, and transported in a manner that ensures they arrive at the final destination laboratory in a testable condition. Personal protection guidelines must be adhered to when collecting or processing specimens; at a minimum, this includes gloves and a mask. In the laboratory, a gown or other protective items may also need to be used. In the field, under suspect NBC conditions, collectors should be in MOPP Level 4 or inside NBC-protected vehicles. Common sense and the clinical and/or tactical situation will determine the extent of personal protection necessary.
- Preservation of specimens, either chemically or mechanically (cooling), will be necessary to minimize the amount of analyte degradation that occurs after removing the specimen from its physiological microenvironment. The optimal preservation technique will vary with different laboratory tests and must be confirmed for each requested assay. While freezing may preserve some serum constituents, freeze-thawing cycles may denature others. Freezing may also completely destroy certain microorganisms. This caution also applies to tissue specimens since "fixing" tissue with a standard 10 percent formalin solution will preserve tissue for special staining techniques; however, it renders the specimens completely useless for microbiological culture. Always verify specimen preservation requirements for storage and transport with the supporting medical laboratory before processing the specimen. Ideally, confirmation of the correct handling conditions should be coordinated before collection.
- The importance of coordinating sample/specimen collection with the supporting laboratory facility cannot be overstated. Contact the receiving laboratory for instructions when doubt exists about the appropriate source, collection technique, storage and preservation conditions (such as, aerobic or [B-5] anaerobic environment), and transportation requirements for samples/specimens. Extremely small volumes of samples/specimens, properly collected and handled, can yield a tremendous amount of information to assist in making medical, tactical, and strategic decisions. Conversely, very large quantities of poorly collected and insufficiently preserved samples/specimens are essentially worthless for most analytical techniques.
- Analysis beyond intratheater capabilities will be coordinated by the supporting laboratory, when deployed, or through medical channels in the absence of an in-theater supporting laboratory.

b. Post mortem and Forensic Specimens. The analysis of specimens from deceased humans and animals can provide valuable information about the disease, organisms, injuries, or environmental conditions at the time of death. This information can greatly enhance the treatment of others affected by the same, or physiologically similar, process. Specimen collection for post mortem or forensic examination is very important; the techniques involved reflect a significant degree of training, experience, and skill. Most specimens will be of the same type and size as for ante mortem specimens, but types and amounts of specimens will be determined by the collector.

(1) The collection of specimens from remains should be conducted exclusively by a pathologist, or other personnel specifically trained in forensic collection techniques. An exception is when Special Operations Forces (SOF) personnel are operating under radio silence conditions; the most qualified medical person with the operation collects, preserves, and transports or coordinates transport of specimens for evaluation. The same chain of custody requirements applies to specimens collected by SOF personnel, as with all other specimens.

(2) A large amount of support information can be gained by analyzing the site of injury and subsequent death. This "site scene" investigation requires a tremendous attention to detail and a trained observer. If forensic personnel cannot be contacted, or will be unduly delayed in arriving at the scene, then photographs of the victim and the immediate surroundings should be made. The scope and extent of the photographs should be composed to reflect as much detail as possible to assist forensic personnel in reviewing the scene retrospectively. In the event that photography is not feasible, detailed sketches of the scene should be made to assist the forensic investigation.

(3) Techniques such as cardiac or bladder puncture, needle biopsy of organs, spinal tap, or exploratory laparotomy will not be performed by untrained personnel unless specifically requested and directed by forensic investigators.

c. Water Sample Collection.

(1) Water samples for identification or verification of biological agent contamination are collected by PVNTMED personnel. The supporting laboratory should provide guidance on sampling procedures and collecting kits for use in collecting the samples. In the absence of guidance, a technique for use of the Sep-PakTM is described in FM 3-19.

(2) When sampling kits are not available, samples may be collected in other available sterile containers. The best containers for use are the 100-ml glass bottles used for collecting routine water samples. All water samples must be collected and placed in a cooler or refrigerator until the sample is transported to its destination. During transportation the samples must be maintained at a temperature between 1°C and 4°C.

d. Food Samples. Veterinary personnel must collect suspect biologically contaminated food samples for submission to the supporting laboratory for in-theater verification of contamination. All food samples must be collected and placed in sterile containers. Place the samples in a cooler or refrigerator until the sample is transported to its destination. During transportation the samples must be maintained at a temperature between 1°C and 4°C.

e. Animal Specimens. Veterinary personnel collect specimens from suspect biologically contaminated/diseased animals. The same types and amounts of specimens are prepared and shipped in the same manner as are human specimens.

f. Environmental Samples. Environmental samples are collected as directed in the operators' manual or other publications for operating collection systems. Example: The Biological Integrated Detection System (BIDS) collects an environmental sample using a single liquid sample collector. The collector is a high-volume aerosol sampling and collection device. On demand it samples ambient air through a two-stage virtual impactor that concentrates aerosol particles in the 2 to 10 micrometer diameter-size range. The concentrate particle stream is directed through a wet collector containing a buffer solution and, over a 45-minute period, a 40 to 50 ml sample is collected. On order or when test results indicate a suspected agent, the sample and associated documentation are packaged and transported IAW FM 3-101-4.

#### B-4. Chain of Custody

a. A strict chain of custody must be maintained for every sample/specimen collected. Use DD Form 1911 (Material Courier Receipt), or other document (such as DA Form 4137 [Evidence/Property Custody Document]) as directed for each sample/specimen collected. The chain of custody document must accompany the sample/specimen during transport from the point of collection to the final receiving laboratory. Each time the sample/specimen is transferred to another individual, the receiving person must sign the document to show that they received the sample/specimen and state what happened to the sample/specimen while in their custody. The document will provide the answer to the following questions:

- When was the sample/specimen collected?
- Who has maintained custody of the sample/specimen?
- [B-9] What has been done with the sample/specimen at each change of custody?

b. The samples/specimens must be appropriately packaged, labeled, and evacuated to the designated medical laboratory for confirmation of a biological attack. The standard chain of custody for the evacuation would be as follows:

- Sampling unit.
- Unit S2/security office or medical operations officer.
- Technical escort unit or other command-designated escort personnel.
- In-theater supporting medical laboratory.
- Designated CONUS laboratory.

### Section II. SAMPLING TECHNIQUES AND PROCEDURES

#### B-5. General

The collection of environmental, and background (control) samples/medical specimens is an integral part of investigating allegations pertaining to the first use of chemical or biological agents. The types of samples/specimens taken and the collection methods primarily depend upon the circumstances encountered by the collector. During all chemical and biological sampling operations, the commander establishes the required protective equipment to fit the situation. This appendix includes a recommended list of equipment for use during chemical and biological sampling operations (Table B-2).

#### B-6. Expended Material

The NBC recon units collect samples under various circumstances. For example, a recon unit may collect samples in an area free of hostile forces. The Special Forces NBC Reconnaissance team may collect samples within the enemy area of operations or deep into the enemy's rear area. Samples include toxic agent munitions, chemical products, air, water, soil, and vegetation. In addition, all expended material used to collect the samples should be turned in to the laboratory with the samples. This material includes items such as expended M256A1 kits, M8 and M9 paper. These items should be recovered, packaged, and shipped with the suspected samples for analysis. Different information may be derived from each type of sample; Table B-3 compares different types of samples.

#### B-7. Environmental Samples

Control or background samples that are collected from clean samples must be identical to the samples collected from the areas near the attack areas as baseline data. The contaminated samples must be compared to the baseline data (control samples). This is especially true if unknown or nonstandard chemical and/or suspected biological agents were employed. The analysis center uses the control samples to compare with a contaminated one. The recon unit collects control samples of soil, water, and vegetation from areas about 500 meters upwind of an alleged attack area. Control samples generically are the same as those collected in an alleged attack area. For example, if leaves from an apple tree in an attack area were collected as a suspected contaminated sample, the recon team should collect leaves (as a control sample) from an apple tree outside of the contaminated area. If water from a pond in the attack area is collected, the recon unit should collect control samples of water from a pond (not a moving stream) in a nearby clean area. The size of an environmental control sample should be about the same as the suspected contaminated sample collected from the attack area (see Table B-4, page B-20).

[B-12]

#### B-8. Collection of Air and Vapor Samples

a. Air is a good sample matrix since it is a well-mixed medium. Air from a sample site contains a static concentration of contaminants. The concentration of contaminants depends upon the flow rate of the contaminant into the environment, the wind speed, and the physical state of the contaminant, the terrain contours, and temperature as a variable. The sample should be taken within 102 meters of a contaminated surface and at the downwind edge of a contaminated area. The method should consist of pumping a given volume of air, by hand or electric pump, through sample tubes.

b. To avoid contamination, persons conducting air sampling should not use cologne, perfume, insect repellent, medical creams, or strong soaps before taking a sample. The fragrances from these products are volatile organic compounds that may be absorbed on the filter and skew analytical results. Smoke also severely interferes with air sampling, therefore, avoid tobacco and vehicle exhaust smoke.

c. The primary method for collecting air samples is with the PAS 1000 automatic air sampler in conjunction with a TenaxTM tube for a total of three to four minutes when possible. Upon completion of sampling, place the TenaxTM tube in a 2¼-inch piglette. Seal the piglette around the cap with either pressure-sensitive or TeflonTM tape. Once sealed, place the piglette into a Mylar or reclosable bag. Fold the bag around the piglette in a circular motion, then apply another bag and fold again. Once the bag is folded around the piglette, use any type tape to secure the bag around the piglette. Place the piglette into a refrigerator or cooler until the sample is transported to its destination.

d. When chemicals are permitted into the atmosphere from a facility, the best places to obtain samples are close to the emission source where the concentration of the chemical is not diluted. The further from the original point of release, the more diluted the sample becomes from mixing with air, water, or environmental pollutants.

e. Natural and man-made terrain features such as hills, valleys, and rows of buildings, sometimes aid the collector by channeling emissions. When these features are associated with a particular facility, their downwind side is a suitable place to collect a sample because the emission remains more concentrated further from the release point.

f. For collection in a possibly contaminated location, and if the situation permits, initially use a detection kit such as the M18A2/M256AI to determine if a possible vapor hazard exists from known chemical agents. Also, use the kit when personnel are required to examine possible toxic agent munitions. In any case, collect air samples with the white-band tubes and save for identification and analysis.

g. Small air samplers also enable the collector to obtain vapor samples from alleged toxic agent munitions at a safe distance while explosive ordnance disposal (EOD) operations are performed. If EOD personnel are not on the scene, the air sampler can be activated, and the collector can stand at a safe distance while the sampler is operating.

h. Perform sampling operations as soon as possible when directed by a higher headquarters or after suspected chemical or biological contamination is encountered.

[B-13]

#### B-9. Collection of Water Samples

a. Water sampling is a matter of collecting enough water to get acceptable information about the contaminants. The collector should provide the analysis center with one C18 and one silica cartridge when using the Sep-PakTM technique or 100 ml in a sterile bottle when Sep-PakTM is not available.

b. General guidelines: If it is believed that the threat has used standard chemical agents during an attack, use the M272 chemical agent water test kit for initial screening and sampling.

c. When collecting water samples using the Sep-PakTM C18 cartridge, the following items are required:

- One 60 cc syringe without needle.
- One 3-way sterile, plastic, stopcock with protective covers.
- One piece of plastic tubing (3/16" inner diameter × 6" long minimum).
- Sterile water or methanol.
- One clean container, such as a TeflonTM cup or glass jar.

d. Prior to collecting each sample, prime the Sep-PakTM system in the following manner:

- Step 1. Attach Sep-PakTM directly to 60 cc syringe.
- Step 2. Pour small amount of sterile water or methanol into container.
- Step 3. Insert tip of Sep-PakTM into container.
- Step 4. Withdraw at least 40 cc of solution.
- Step 5. Detach Sep-PakTM from syringe and discard solution from syringe.
- Step 6. Repeat steps 3 through 5 using the same syringe.

e. After priming the Sep-PakTM, assemble the components in the following configuration:

- Attach the 3-way stopcock to a 60 cc syringe.
- Attach the Sep-PakTM to the opposite end of stopcock.
- Attach the plastic tubing to the open end of the Sep-PakTM.

f. Use the following procedures to collect samples with Sep-PakTM:

- [B-14]Step 1. Ensure that the lever on the stopcock is turned sideways with the off arrow pointed toward the large outlet port.
- Step 2. Place the open end of the plastic tubing into the water near the bottom, without touching the bottom or sides of the body of water.
- Step 3. Draw 60 cc of water into the syringe.
- Step 4. Turn the stopcock lever to the off position by positioning the lever to point toward the stopcock.
- Step 5. Push the plunger all the way in, discharging the water from the syringe through the outlet port.
- Step 6. Repeat steps 1 through 5.
- Step 7. Detach a plastic tubing from the Sep-PakTM, and discard it as contaminated waste.
- Step 8. Detach Sep-PakTM from 3-way stopcock; place into sample container; seal with pressure-sensitive tape; and mark for Identification.

NOTE

You should take a minimum of four samples: three samples of the suspected contamination and one control sample from a nearby unaffected (none contaminated) area for reference.

- Step 9. Dispose of the syringe and stopcock as contaminated waste.
- Step 10. Insert the sample container in a cooler or refrigerator until the sample is transported to its destination.

g. For samples to be representative of the overall contaminated area, the collection point should be carefully selected. Collect samples from—

- Drains and slow-moving streams, since contamination and dilution from other sources are minimized.
- Stagnant pools of water if the pools of water are part of chemical waste areas, such as a landfill or chemical disposal area. Chemicals may percolate into stagnant pools or sumps close to the site.

[B-15]

NOTE

If an oil film, globules of organic materials, or an unnatural appearing powder-like material is visible on the water's surface, collect a surface sample of the material. If not, collect the sample from near the bottom of the water source (stream, lake, pond, water container). The upper layers of water may have lesser amounts of contaminants, due to higher temperatures that promote decomposition. Since most chemicals of interest are more dense than water, contaminants usually sink to the bottom of the water source.

h. Collect the sample without the Sep-PakTM by immersing a capped or stoppered container to the desired depth, removing the cap or stopper, letting the container fill, and then capping the container. An alternate method for deeper water is to use a plastic, pump-operated siphon to pump water from a specific depth.

i. The best time to collect a sample of water from a location is when intelligence or local reports indicate that a process of possible interest is ongoing. In the absence of reliable reporting, this may be indicated by increased activity, higher than normal amounts of security, or increased flow from facility chimneys or water discharge pipes. In field areas where a toxic agent has been sprayed or disseminated over a land area, the best time to collect water samples is just after the start of a rainstorm when runoff is beginning. Natural surface drainage will concentrate any remnants of toxic compounds in depressions, streams, or ditches.

#### B-10. Collection of Soil Samples

Soil is a suitable medium to collect as samples for toxic organic compounds. A critical point, however, is that the precise site of the agent deposition must be sampled for best results. Contamination may be recognized by discoloration or apparent deposition of material on the soil's surface. If discoloration or deposits of material are evident, only collect the discolored soil or deposited materials, if possible. Dead, malformed, and wilted foliage is an indicator of contamination. Soil samples should be collected from open areas, along the drip line tents, stationary equipment, bottom of ditches and terrain depressions.

a. Collect the soil samples by using a knife, spoon, spatula, or similar item to scrape a square of topsoil (2×5×1 centimeters) from areas that appear to have been contaminated in to a collection container. If chunks or clods of earth are collected, select those that are no larger than 10×5×1 centimeters (see Table B-4). Also, collect a control sample of soil of the same type and texture from a nearby uncontaminated area.

b. Use a glass bottle, jar, or TeflonTM jar as the container when available. When these containers are not available, Mylar bags may be used. When using a glass bottle, jar, or TeflonTM jar, seal the cap with either pressure-sensitive or TeflonTM tape, and mark for identification. When using Mylar bags, place each sample in a separate bag, push excess air out, and seal by folding the open end over two to three times [B-16] and wrapping the bag with tape. Insert the first bag into a second bag, seal, tape, and mark for identification. If possible, place the samples in a piglette.

CAUTION

Avoid direct contact with the sample to prevent exposing yourself to the suspect agent (MOPP 4 is required).

c. Collect samples as soon as possible when directed, upon detection of a suspect substance, or after the alleged incident.

#### B-11. Collection of Contaminated Vegetation

As with soil samples, vegetation is also a suitable medium to collect as samples for toxic organic compounds.

a. Collect samples of vegetation that appear to be different from normal. Select leaves that have wilted or appear to have been chemically burned. Collect samples of vegetation that appear to have liquid or solid substances deposited on their surfaces (this may be noticed as a shiny or moist area).

b. Collect samples of vegetation at several locations within the suspected contaminated area. Using a cutting tool or any sharp object, cut several affected leaves and/or a handful of grass whenever possible. Do not crush the sample. Place the sample into a Mylar or reclosable bag. Squeeze excess air out of the bag and seal it. Fold the open end of the Mylar bag over two to three times, and wrap it with tape. The minimum size for a sample is three leaves or three handsful of grass. One leaf is of little value, but is better than nothing. Bark is acceptable but not preferred. Mark the bag for identification. Take a control sample of similar material from an unaffected (uncontaminated) area. Fold, seal, tape, and mark the control sample in the same manner as the actual sample.

c. When it is possible to determine a probable center of attack in an area, collect vegetation samples near the center of the area, about 100 meters upwind of the area, and in several 100-meter increments downwind of the area. If the collector can discern a contamination pattern in the area, this should be reported.

#### B-12. Medical Specimens

a. Just as blood and urine specimens are taken from humans who were allegedly exposed in an attack, also collect specimens from individuals who claim not to be affected by a toxic agent and are from the same group as exposed personnel. The purpose is the same as collecting environmental control specimens; that is, to determine if a toxic substance is present in the individuals' natural environment or if it has been artificially introduced.

[B-17]

b. Selection of humans for control sampling is somewhat more complicated than selection of environmental control samples. This is because ethnic diets, racial differences, physiological makeup, and actual living conditions of persons who are outwardly similar may introduce potentially large deviations. Each of these factors must be accurately considered before selecting subjects as controls.

c. Consideration of ethnic diets is important because of unique foods or methods of food preparation that may exist. As an example, individuals in settled areas may purchase beer that has been carefully filtered and sterilized, while individuals in a nearby unsettled area may ferment their own beer by burying home crafted jugs in the ground and extracting the product little by little over several months.

d. Racial differences can account for differences in mortality and morbidity rates in specific populations. One example of this could be the high rate of hemophilia in a population versus the rarity of the disease in another.

e. Physiological makeup is critical because of the differences in hormone balance and tissue composition in males, females, adults, and juveniles. For this reason, medical control specimens should be drawn from individuals of the same gender and approximate age as specimens from exposed personnel, if possible.

f. Differences in the actual living conditions of people also require a close look. The point here is that conditions in remote, semicivilized camps are seldom the same as those in a well-established camp that has access to modern amenities.

g. The bottom line in selecting subjects for medical control sampling is that they be as similar in all aspects as possible.

#### B-13. Collection of Medical Specimens

a. Trained medical technicians or physicians should collect medical specimens (human or animal); however, Special Forces NBC Reconnaissance team personnel are trained to do this procedure. Remember, the collector must have express permission (authority) to collect medical specimens from the dead, because of religious beliefs in many cultures. To obtain such specimens without permission may result in unnecessary mission complications. Ensure all personnel handling or collecting medical specimens have received proper immunizations for their own protection. They must be inoculated IAW The Surgeon General's guidance.

b. Medical specimens collected during an investigation include blood, urine, sputum, nasal swabs, and tissue specimens from living victims and blood and urine specimens from unexposed persons (background control specimens).

c. Collect blood specimens using either a standard 10 cc disposable syringe with a 1- to 1½-inch needle (20 to 22 gauge), or by using a VacutainerTM system. When using a VacutainerTM system, ensure that multiple specimen needles and "red top" vacuum tubes are used. Ten cc of blood is sufficient for analytical testing. Do not take more than 5 cc from small, malnourished children. After blood is collected, it should be transferred to a polypropylene-type container and sealed with parafilm before transporting. [B-18] All body fluids should be collected without violating antiseptic techniques. Also, prior to transporting specimens, collectors need to check specimen containers for paper labels IAW guidelines for labeling medical specimens. Collect blood specimens using the following materials equipment:

- Gloves.
- 10 cc sterile, disposable syringe.
- 1- to 1.5-inch sterile needle (20 to 22 gauge).
- VacutainerTM device (adapter with needle).
- Constricting band.
- Disinfectant pads, Betadine, or alcohol.
- Sterile 2×2-inch gauze pads.
- Labels.

NOTE

Gloves should be worn whenever handling medical specimens. Do not freeze liquid blood and urine specimens (ideal cooling temperature is between 35° and 40°F [2° to 4°C].)

d. Collect urine specimens using either a standard urine cup or by a urine catheter and urine cup. When collecting the specimen directly into a urine cup, the person must urinate into the cup until sufficient fluid is collected (40 cc of urine is preferable, although 10 cc can support analytical testing). When the person is unable to urinate, the catheterization technique is preferable. The catheterization technique is best performed in a clinical environment. As with other body fluids collected, urine must be kept cold. Do not freeze.

NOTE

For correct procedures on catheterization refer to STP 8-91W15-SM-TG.

e. Collect tissue specimens using sterile scissors and forceps or as directed by the attending physician.

[B-19]

(1) When casualties have unidentified skin lesions, photographs of the lesion(s) and overall photos of the extent of the lesion(s) should be taken, using color film before biopsy. A specimen of the lesion should be obtained. This is done by surgically removing a portion of the skin with a sterile pair of scissors and forceps.

(2) Place tissue specimens in a TeflonTM container filled ¼ inch from the bottom with a preservative, (formalin 10%) for preservation of the specimen until it reaches its proper destination. Seal the container and lid with parafilm. As with any other medical specimens, tissue specimens are refrigerated prior to shipment; but do not freeze tissue specimens.

f. Collect nasal swabs by using a cotton-tipped swab. Place the swab with collected specimen in a TeflonTM container filled ¼ inch from the bottom with a preservative for preservation of the specimen until it reaches its destination. Seal the container and lid with parafilm. Refrigerate the specimen for shipment, but do not freeze.

g. Collect sputum by having the patient discharge the sputum into a small, sterile screw-top jar or urine specimen cup. Seal the container and refrigerate the specimen for shipment, but do not freeze.

#### B-14. Post mortem Specimens

Post mortem specimens should be collected by individuals trained in forensics. When forensics-trained individuals are not available, the most qualified medical person should collect human specimens. Specimens from animals should be collected by veterinary personnel. In either case, the following specimens are collected:

- Blood. Use a 50 to 60 cc sterile syringe with an 18-gauge, 5-inch (large bore) needle to collect blood from the heart, and urine directly from the bladder. Use a spinal needle to collect cerebral spinal fluids. Three of each type of specimens must be collected.
- Lungs. A biopsy needle is needed to properly collect lung tissue specimens. After collecting specimens from the lungs, place specimens in a plastic or TeflonTM container filled with 10% formalin (preservative) and seal the container for transporting to its destination.
- Liver. If possible collect liver core specimens, using a large-gauge needle (18-gauge, 5-inch long) via intercostal or abdominal puncture. Or, if the family consents, perform a minilaparotomy and obtain one or two 2×2×2 cm sections of liver. Store and package the specimen as directed for tissue specimens. For suspect biological agents, see Table B-1 for specific types of specimens, amount, collection medium, and from whom to collect.

NOTE

Before attempting any of the above procedures, collector must be certified by a qualified person (medical doctor) on the correct procedures to collect specimens from cadavers.

#### B-15. Reporting, Packaging, and Shipment

Although a sample/specimen collected from an alleged attack area can be significant, it can become useless if proper steps are not taken to record critical information about its collection or if it is improperly packed and breaks during shipment to an analysis center. This section discusses the information needed when acquiring samples/specimens and the preferred methods for handling and packing samples/specimens for shipment.

[B-21]

a. A complete background information history of the circumstances about each sample's/specimen's acquisition must be provided to the agency analyzing the sample/specimen.

b. Critical background information includes—

- Circumstances of acquisition. How the sample/specimen was obtained, where it was found, and how it was collected.
- Physical description. The physical state (solid, liquid, powder, apparent viscosity), color, approximate size, identity of the specimen (such as military nomenclature), dirt, leaves, or so forth.
- Circumstances of agent deposition. The type of delivery system, a description of how the weapon functioned, how the agent acted on release, sounds heard during dissemination, a description of any craters or shrapnel found associated with a burst, and colors of smoke, flames, or mist that may be associated with the attack.

c. Provide information on the agent effects on vegetation for soil or environmental samples. A description of the general area (jungle, mountain, grassland) and changes in the vegetation after agent deposition (such as color change, wilting, drying, dead) in the main attack and fringe areas.

d. Provide information on the agent effects on humans for medical specimens. Describe how the agent affected personnel in the main attack area versus fringe areas; the duration of agent effects; peculiar odors that may have been noticed in the area prior to, during, and/or after an attack; measures taken that alleviated or deteriorated the effects; and the approximate number of victims and survivors, to include their ages and genders.

e. Describe the agent effects on animals. Provide information on the types of animals that were or were not affected by an attack and of how they were affected.

#### B-16. Handling and Packaging Materials

Materials used for packaging samples/specimens primarily consist of Mylar collection bags, TeflonTM specimen jars and tubes, pigs and piglettes, ice chests, sealing materials, and wrapping and cushioning supplies.

a. Collection Bag. Use the Mylar bag as the initial container for such samples as protective masks and filter canisters, individual antidote and decon kits, munition fragments, and other items too large to place in a specimen jar. Use it also to package sample/specimen containers to ensure a vapor barrier in case the container is broken in transit. The bag acts as an initial or secondary vapor barrier to prevent air from leaking inward and toxic material outward. Follow the procedures below when using the bag.

- If packaging a specimen container or nonenvironmental sample/specimen, first, verify it has a sample/specimen number. Carefully place the sample/specimen in a bottom corner of the Mylar bag.
- [B-22] Squeeze all the air out of the bag and seal it by removing the adhesive's protective strip, and pressing the two sides together.
- Place a piece of 2-inch-wide fiber or cloth tape across the end of the bag that you just sealed to reseal the Mylar bag on the outside. This serves as extra insurance in case the internal seal is broken.
- With the bag lying in front of you and the seal at the top, fold the bag across its width to as small a size as possible without damaging the sample/specimen. At this point, use tape to hold the fold. Next, fold the bag from the top down to the bottom of the bag to as small a size as possible. The sealing of the bag is the most critical step during the packaging process.
- At this point, turn the bag over and use a marker or file label to put the sample/specimen number on the outside of the bag so that analysis center personnel can identify the sample/specimen.
- Place the folded Mylar bag in a clear plastic reclosable bag, if available. Following the same steps you used for the Mylar bag, fold and seal the plastic bag. When this has been completed, again mark the sample/specimen number on the exterior of the bag.

b. Glass Specimen Jars and Polypropylene Tubes. Use glass containers to hold small environmental samples, water samples, and medical and post mortem specimens. Use polypropylene containers to hold medical specimens such as blood or urine. Polypropylene containers may be used for post mortem specimens if required; however, glass containers are preferred. The use of glass rather than plastic containers is preferred for environmental samples because toxic agents may leach chemicals from plastics into a sample, introducing contamination and confusing the analysis efforts.

- If the container has a screw-on lid, place TeflonTM plumber's tape (NSN 8030-00-889-3535; Tape, Antiseize) on the threads of the container before putting on the lid. This helps to limit the leakage of liquids and vapor from the container and to assure the lid will not fall off while in transit. If the lid has a cardboard liner, remove the liner and replace it with one or two layers of parafilm (a laboratory sealant film).
- Once the lid is on, stretch parafilm around the outside of the container at the junction of the lid and the glass. Two wraps of the film are enough to provide a leakage barrier and more assurance that the lid cannot fall off.
- At this point, ensure the sample/specimen number is on the outside of the container. Use a diamond etching pencil or an adhesive label to put the sample/specimen number on the exterior of the container.

c. Six-Pound Metal Can. Use metal cans as the external container for packaging small items that have been sealed in Mylar bags, specimen jars, and polypropylene tubes containing medical specimens. The metal can helps absorb shock from rough handling during shipment and eliminates the spread of contamination if a specimen container is broken. The six-pound metal can is capable of holding more than one sample/specimen (depending upon size of samples/specimens).

[B-23]

- Before placing samples/specimens in the can for shipping, ensure a sample/specimen number is assigned and is visible on each item.
- Place about 1 to 2 inches of packing material in the bottom of the can.
- Wrap jars and tubes in plastic bubble wrap or ⅛- to ¼-inch-thick foam rubber sheeting, secure the wrap with tape or a rubber band, and place the wrapped item in the can.
- If bubble wrap or foam rubber is not available, use newspaper. The guiding principle is that the sample/specimen containers should fit snugly and not be able to move in the can.

d. Ice Chest. Standard polyethylene or metal ice chests are the most easily procured items used for transworld shipment of CB samples/specimens. The most easily used size is about 24 inches long by 18 inches high by 15 inches deep. This size permits the sender to ship two or three 6-pound metal cans in each chest with sufficient dry ice to maintain freezing temperatures for about four days. Also, each chest remains at a weight that one individual can handle.

e. Transport Container. When the samples/specimens must be transported on commercial aircraft, an IATA-approved sample transport container must be used for shipment/delivery to the CONUS laboratory.

f. Coolants. Samples/specimens submitted for laboratory analysis must be properly packaged, labeled, and shipped to ensure they arrive in an analytically acceptable condition. All samples should be maintained at a temperature of 1° to 4°C during transport. Ideally, samples/specimens should arrive at the in-theater laboratory within 6 hours of collection. The samples/specimens should be delivered to the CONUS laboratory within 24 to 48 hours. If the samples/specimens cannot be delivered to the CONUS laboratory within this time, then they should be flash frozen to -165°C, if capabilities are available. If available, dry ice should be used when flash freezing cannot be accomplished. If the samples/specimens cannot be delivered to the CONUS laboratory within 24 hours, the supporting laboratory should subculture the samples/specimens and send the subculture with the samples/specimens to the CONUS laboratory. The subculturing date should also be provided.

g. Internal Insulation. While a commercial ice chest provides good insulation of both the samples/specimens and the coolant, it is best to place extra insulation and cushioning around the metal cans inside the chest. Newspapers, plastic bubble wrap, and foam rubber may all be used with almost equally good results except newspapers and standard ice do not mix well.

#### B-17. Collection Reporting

a. The collector must provide a formatted message for transmission as soon as possible to report acquisition and shipment of samples/specimens. During special operations in a theater in which a Special Forces Group (SFG) is deployed, the message is transmitted by the fastest means through the fewest channels to the NBC control (NBCC) center. If a NBCC center has not been deployed to the area of operations, as in low-sample/specimen volume peacetime NBC sampling operation, the message is [B-24] transmitted by the fastest means through the fewest channels to the message addressees below. In addition, a written report accompanies each sample/specimen or batch of samples/specimens. The collector ensures that the acquisition message has been properly classified.

b. The collection report includes at least the following addressees:

SECSTATE WASHDC
SECDEF WASHDCHOSD-ISA/OUS-DREH
JCS WASHDC//J-3/J-5H
CIA WASHDCHOSWR-STD-LSBNIC-NIO(STP)H
DIA WASHDC//DT-3B/DT-5A//

MDHSMCCR-OPF/SMCTE-OPE-RA-ID2H
CDR FSTC CHARLOTTESVILLE VA//AIAST-RA-ID2H
CDR USAMRIID FT DETRICK MD (For suspect biological samples/specimens only.)

c. A collection message contains the following information:

- The sample/specimen identification number is part of the subject line if only a single sample/specimen is referred to in the text. Otherwise, refer to the sample/specimen number within the message body with its background information.
- The shipment date, mode of transportation, courier identification, air bill of lading number, flight number destination, and estimated time of arrival are included if the sample/specimen is to be shipped immediately. Also, the material courier receipt form (DD Form 1911) should be used to maintain chain of custody.
- Background information on the sample/specimen. Questionable circumstances surrounding acquisition of a sample/specimen. The name of another country or agency that acquired a sample/specimen from the same event or area and is not shown on the message address.
- A recommended priority and rationale for analysis to guide the analysis center on the assessment of the potential value of the sample/specimen.
- All details relating to the collection of the sample/specimen, regardless of how insignificant they may seem to the collector.

d. Ship all samples/specimens by the fastest, safest means, preferably by a technical escort unit (TEU) to the theater Chemical-Biological Sampling Control Element (CBSCE) or to a location the CBSCE designates. If there is no CBSCE in the theater, send the samples/specimens IAW preplanned instructions from the Chemical-Biological Sampling Control Center (CBSCC) at CBDA, Aberdeen, Maryland. The CBSCC uses the following criteria to determine the final destination of each sample:

[B-25]

- Is the sample/specimen chemical or biological in content?
- Is the sample/specimen content completely unknown?
- Is the sample/specimen a possible biological material?

(1) In any case, the NBCC center must be notified in advance of shipment of the sample so additional instructions or deviations from standard instructions can be given. Figure B-l shows an example of a shipping notification message. The NBCC center will direct, in advance, that samples be sent to one or more of the following locations, depending on the category of the samples. Prior to shipment of samples/specimens, contact must be made with—

Commander
Technical Escort Unit
ATTN: SMCTE-OPE
Aberdeen Proving Ground, MD 21010
DSN: 584-4381 (Duty hours) DSN: 584-2773 (After duty hours)

(2) This unit controls the transport of samples/specimens to their final destination(s). Do not ship suspected toxic samples/specimens or munition systems to CONUS technical centers or intelligence agencies without coordination and prior approval by the recipient.

NOTE

Suspect CB samples/specimens are first delivered to the supporting medical laboratory in the AO for in-theater analysis before they are transported out of the AO. The supporting laboratory will withdraw an aliquot of selected samples/specimens for analysis. The supporting medical laboratory is responsible for providing the AO commander confirmatory identification within the AO. The CONUS-based reference laboratory is responsible for providing confirmatory identification for President and Secretary of Defense purposes.

## APPENDIX C
GUIDELINES FOR OPERATIONAL PLANNING FOR HEALTH SERVICE SUPPORT IN A NUCLEAR, BIOLOGICAL, AND CHEMICAL ENVIRONMENT

#### C-1. General

As the HSS unit prepares for its support role, NBC, TIM, and CBRNE considerations must be included. This appendix provides guidelines for HSS planning, preparing for, and conducting operations in an NBC environment and responding to a homeland defense CBRNE event.

#### C-2. Predeployment

When preparing the unit's mobilization plan and TSOP, include the supplies and equipment that will be required for the unit to operate in an NBC environment. DO NOT wait until ordered to mobilize to begin preparation for the mission. A well-prepared and trained unit stands a much better chance of surviving and accomplishing their assigned mission. At a minimum include the following:

- Nerve agent pretreatment and antidotes (see FM 8-285).
- Blister agent antidote/treatment (see FM 8-285).
- Incapacitating agent treatment (see FM 8-285).
- Lung-damaging agents (choking agents) treatment (see FM 8-285).
- Blood agent (cyanogen) treatment (see FM 8-285).
- Biological agent immunizations and chemoprophylaxis (see FM 8-284).
- Biological agent treatment (see FM 8-284).
- Nuclear and radiological treatment (see FM 4-02.283).
- Protective mask with hood for each individual (see FM 3-4).
- Replacement filters for protective mask (see FM 3-4).
- Two sets of MOPP per individual assigned to unit (see FM 3-4).
- All authorized radiation detection equipment.
- All authorized chemical agent detection equipment.
- All authorized NBC alarm systems.
- Biological agent detection equipment, if available.
- [C-2] Sample/specimen collection, packaging, and shipping supplies for suspect NBC agents.
- Decontamination equipment and supplies (DS2, STB, pails, sponges, mops, decontaminant application apparatus, individual skin decontamination kits, and individual equipment decontamination kits [see FM 3-5]).
- Material for covering supplies and equipment (such as plastic sheeting, tape, and tarpaulins).
- Material for preparing improvised protection in shelters (such as plastic sheeting, tarpaulins, tape, and sandbags).
- Collective protection shelter systems with repair parts, if available.
- Chemical agent patient decontamination Medical Equipment Set (MES). The MES can also be used to decontaminate nuclear and biological patients, if authorized.
- Chemical agent patient treatment MES. Some components may also be used to treat nuclear and biological patients, if authorized.
- Water supply for patient decontamination, if required.
- Shovels, picks, and axes.
- Lightweight decontamination system M17 and other decontamination apparatuses.
- Applicable references (Army Regulations [ARs], Joint publications, FMs, technical manuals [TMs], training circulars [TCs], and TSOPs).

#### C-3. Mobilization

During mobilization the unit must ensure that all supplies and equipment are on hand and are serviceable. Commanders and leaders must also ensure that—

- Movement plans are prepared.
- Transportation support requirements are identified and requested.
- Load plans include provisions for the transportation of NBC supplies and equipment (medical and nonmedical).
- A MOPP level has been established for the movement, if applicable.
- A checklist of training shortfalls is prepared and a training plan is in place.[3]

[C-3]

#### C-4. Establish a Medical Treatment Facility

Plans for establishing a BAS, DCS, or FST for operating in a NBC environment must include employment of CBPS systems. When establishing a hospital using Deployable Medical Systems (DEPMEDS), the chemically protected (CP) DEPMEDS must be set up as the conventional shelters are being set up. Once the conventional shelter has been set up and is operational, CP DEPMEDS cannot be established without first taking down the existing shelter. Follow the technical manual provided with the CP DEPMEDS system issued to your unit. Plans for operating a DEPMEDS equipped hospital in the NBC environment should include, but not be limited to—

- Coordinating with the supported unit to ensure unit casualty collecting points and patient decontamination points are on the HSS template. If possible, integrate HSS units/elements into local units NBC detection systems and communications systems.
- Surveying the AO. Survey the area to ensure contamination is not present before establishing the MTF.
- Establishing detection stations on the unit's perimeter.
- Determining direction of prevailing wind. All contaminated patients, ambulances, and helicopters must arrive on the downwind side of the MTF; this must be done with or without CPS.
- Setting up the contaminated triage, patient decontamination, and contaminated treatment areas (including overhead cover).
- Establishing the contaminated ambulance point.
- Establishing the contaminated helicopter landing area.
- Preparing the contaminated waste dump.
- Establishing the clean ambulance point.
- Establishing the clean helicopter landing area.
- Marking the hot line and preparing the shuffle pit.
- Employing CP DEPMEDS system (close shelter, turn on CB filtration units, close air locks, and maintain overpressure), if available.
- Establishing the clean treatment area 30 to 50 yards (meters) upwind of hot line, when CPS is not available.
- Ensuring provisions for overhead cover at the patient decontamination area.
- [C-4] Requesting patient decontamination personnel from supported units for the BAS and DCS, or from units located within the geographic area for hospitals.
- Requesting issue of chemical patient treatment and chemical patient decontamination MESs, if not on-hand.
- Establishing contamination monitoring procedures in CPS.
- Establishing control procedures for personnel crossing the hot line (through the shuffle pit).
- Establishing CPS entry and exit control procedures (see Appendix F).
- Making improvisations; if the MTF must operate in a nuclear/radiological environment. For optional improvisations, see Appendix H.

#### C-5. Operate a Medical Treatment Facility Receiving Contaminated Patients

Individuals should have decontaminated themselves or have been decontaminated by unit personnel; however, an MTF must plan for and be prepared to receive contaminated patients. The patients may not have been decontaminated at the unit, or they may have become contaminated en route to the MTF. Selected CSHs may be designated as the primary NBC MTF and be augmented with additional supplies and medical staff. When designated as such, plans must be prepared designating the location of the CSH that can best support the forward deployed MTFs. All actions listed in paragraph C-4 must be taken. During operations, actions that must be taken are—

- Establishing a MOPP level commensurate with the operation.
- Requiring all ambulances and helicopters with contaminated (or suspected) patients to stay downwind of the MTF.
- Conducting initial triage, decontamination, and contaminated treatment downwind of the clean treatment area (Appendixes F and H).
- Ensuring all personnel crossing the hot line are decontaminated.
- Monitoring personnel entering clean area to ensure that they are contamination free.
- Monitoring for contamination in the clean treatment area (with or without CPS).
- Establishing an internal monitoring program to periodically verify that the MTF is contamination free.
- Monitoring CPS for entry of contamination.
- [C-5] Providing protection for patients if contamination enters the MTF.
- Ensuring personnel drink sufficient quantities of water to prevent heat injury (see FM 21-10).
- Providing protection for personnel and patients in a cold environment. Use sheltered/heated area for patient decontamination.
- Providing protection of personnel and patients in a hot environment.
- Controlling contaminated waste.
- Isolating biological agent patients, if necessary, to control spread of agent/disease (see FM 8-284).
- Protecting supplies and equipment from contamination.
- Providing medical resupply to clean areas.
- Providing food service for personnel and patients in CPS.
- Providing latrine facilities in CPS.
- Providing drinking water in CPS.
- Providing waste disposal support. Remove waste from the CPS at least two times dally. More frequently if large amounts are collected or if odors become a problem.
- Collecting suspect BW agent specimens from patients. Packaging, preparing chain of custody document, and shipping specimens to supporting medical laboratory.

#### C-6. Preventive Medicine Services

Plans for providing preventive medicine services must include monitoring water supplies for contamination. To perform this mission, equipment and supplies must be available and operational. Essential equipment and supplies include—

- Radiation detection equipment such as AN/PDR77, AN/PDR27, AN/VDR2.
- Preventive Medicine Water Quality Control Set.
- M272 Chemical Agent Detection Set.
- Biological sample collection kit, shipping containers, refrigerant, and chain of custody forms.[6]

[C-6]

#### C-7. Veterinary Services

Plans for veterinary services must include provisioning for treatment to government-owned animals and quality control of food supplies. To perform their mission, essential supplies and equipment include—

- Treatment for NBC injured animals. Especially, antidotes and treatment for CB agents.
- Radiation detection equipment.
- M272 Chemical Agent Detection Set.
- Biological sample/specimen collection kit, shipping containers, refrigerant, and chain of custody forms.

#### C-8. Dental Services

Most dental services at the dental treatment facilities will have to be suspended in NBC contaminated areas due to a lack of CPS. Plans must include for emergency dental services to be provided in a clean area or in an MTF with a CPS. Essential supplies and equipment include—

- Dental treatment set for maxillofacial injuries.
- Material for covering and protecting supplies and equipment.

#### C-9. Combat Operational Stress Control

Although specific supplies and equipment are not required for COSC, plans must be prepared to provide these services under NBC conditions. The COSC staff must locate clean areas to conduct COSC activities or manage the COSC patients in a MOPP level commensurate with the command MOPP guidance.

#### C-10. Medical Laboratory Services

Planning for medical laboratory support must include plans for conducting analysis on suspect NBC samples/specimens. Designated supporting medical laboratories must be prepared to analyze and provide confirmation/identification on specimens/samples of suspect NBC agents from humans, water sources, food supplies, and the environment (air and soil). The samples/specimens may be collected by MTF personnel, chemical corps personnel, PVNTMED personnel, veterinary personnel, or other services personnel. To perform this mission, supplies and equipment should include—

- General supplies and equipment.

- Biological sample/specimen collection kits and supplies. To provide capabilities for others to collect samples/specimens (in the event that they do not have these items otherwise available).
- [C-7] Biological test kits or apparatus.

- Microbiology services.

- Immunology/serology MES.
- Microbiology MES.
- Laboratory, general MES.

- Veterinary services.

- Laboratory, veterinary MES.
- Veterinary postmortem field MES.

- Preventive medicine services.

- Water, biological sampling and analysis supplies and equipment.
- Radiation protection MES.
- Entomology MES.
- Alpha/beta detectors.
- Microscope, phase.
- Ambient air analyzer.
- Epidemiology MES.

#### C-11. Health Service Logistics

Plans must include health service logistics support to continue under NBC conditions. To continue this role, all supplies must be protected from contamination. Materials required include—

- Detection equipment.
- Plastic sheeting.
- Tape.
- Tarpaulins.
- [C-8] NBC detection equipment such as, M8 chemical agent detection paper, M9 chemical agent detection tape, radiation detection equipment, and biological agent sample/specimen collection supplies.

NOTE

This guideline contains items that are required specifically for HSS operations in an NBC environment. The items are in addition to supplies and equipment required for conventional operations. This guideline is not all inclusive, but is a starting point for HSS units to develop their specific guidelines.

#### C-12. Homeland Security

Health service support units and installation medical activities/centers must be prepared to provide support in the event that CBRNE are used on the United States. Medical commanders and leaders should develop plans on how the provision of medical support will be provided to a CBRNE event. The plan should include, but not be limited to—

- Number and type of units required to respond.
- Medical equipment and supplies required.
- Personal protective equipment required for medical response personnel.
- Time required to prepare unit/personnel to respond.
- Length of time response support is required.
- Sources for food, shelter, local transportation, and resupply of expended or lost equipment and supplies.

## APPENDIX D
MEDICAL PLANNING GUIDE FOR THE ESTIMATION OF NUCLEAR, BIOLOGICAL, AND CHEMICAL BATTLE CASUALTIES

### Section I. INTRODUCTION

#### D-1. General

The primary purpose of the Medical Planning Guide for the Estimation of Nuclear, Biological, and Chemical Battle Casualties—AMedP-8(A), a three-volume publication for NBC, is to assist medical planners, medical logisticians, and medical staff officers in predicting NBC warfare contingency requirements for HSS personnel, medical materiel stockpiles, patient transport or evacuation capabilities, and facilities needed for patient decontamination, triage, treatment, and supportive care. The optional use of these guides is for projecting medical NBC operational estimates at brigade, division, corps, and EAC.

NOTE

The use of "the guide" in this appendix refers to AMedP-8(A), Volume I, II, or III. The AMedP-8(A), Volume I, II, or III, is the text for each of the STANAGs. The contents of this appendix are extracts from Sections 1, 2, and 3 of the guide.

#### D-2. Medical Planners' Tool

Medical planners' estimates (such as casualty, logistics, evacuation, and personnel cross leveling) must be modified for the NBC environment. Estimates of NBC medical workload can be found in AMedP-8(A). A compact disk containing these documents and an automated version of AMedP-8(A), the Casualty Requirements Estimation Tool (CREST), can be obtained from Headquarters, Department of the Army, ATTN: DASG-HCZ-FD, 5109 Leesburg Pike, Falls Church, VA 22041-3258. The CREST is primarily an Army tool focusing on corps, brigades, and battalions, but also models aerial ports of debarkation, seaports of debarkation, and other units.

This Section Implements STANAG 2475.

### Section II. MEDICAL PLANNING GUIDE FOR THE ESTIMATION OF NUCLEAR, BIOLOGICAL, AND CHEMICAL BATTLE CASUALTIES (NUCLEAR)—AMedP-8(A), VOLUME I

#### D-3. General

a. Volume I of the guide provides estimates of casualties and remaining operational strength after a nuclear detonation in a brigade-sized unit during an out-of-area contingency operation. These estimates [D-2] include the numbers, injury type (initial nuclear radiation, blast, and thermal injuries), and injury severity of nuclear patients based on several brigade scenarios. The scenarios include three different brigade-sized units, in warned or unwarned posture, which have single detonation of 5, 20, or 50 KT in the unit area.

b. The guide is organized into 10 sections. Section 1 introduces the guide and presents background and medical planning considerations. Section 2 provides information on the methodology used to develop the estimates of fatalities, casualties, and effectiveness of individuals remaining in the unit. Section 3 explores the use of the casualty prediction tables based on combat effectiveness decrements and estimates of the number of casualties categorized by insult level. Sections 4 through 10 contain tables of casualty estimates.

c. A sample of this information is graphically depicted in Tables 1-1 and 1-2 of the guide. The casualty estimates used to prepare these tables are presented in the guide as Tables 6-4 and 10-4 in Sections 6 and 10 respectively. The use of these tables is explained in paragraphs 3.1 through 3.6 of the guide. Paragraphs 3.7 and 3.8 of the guide discuss how to use the guide for situations not explicitly addressed.

d. The effects of residual radiation on personnel are not included in the guide. AMedP-6 and AMedP-7 provide information on planning, operations, and treatment for a residual radiation situation. Also not included is the impact of tumbling; impact of glass shards from windows of vehicles or buildings; crushing deaths from building failure; or COSC casualties; thus causing underestimations on the number of patients. Further, there will be personnel who get radiation doses or burns and do not seek medical care.

e. A nuclear detonation may introduce new levels of destruction to the battlefield. There is very little experience with nuclear effects and there is certainly no experience with these weapons on a modern, highly technological battlefield. Therefore, there is little historical data on which to base estimates of personnel injured. Computer simulations are generally used to estimate numbers of personnel injured. Although these estimates may include significant uncertainty, they provide the best estimates to date.

#### D-4. Medical Planning Considerations

a. For effective mass casualty management, key medical and related considerations must be well planned and practiced. These include on-site triage and emergency care, communications, health service logistics, evacuation by ground and air resources, and personnel training in self-aid/buddy aid. Plans need to be made for requirements that may differ from the usual combat situation. For example, in combat situations, severe burn injuries in large numbers are relatively uncommon. Therefore, no special planning for the care of large numbers of burn patients is required. In a nuclear environment, this may not be true, and consideration must be given to the increased need for medical support that would result from a high incidence of burn patients.

b. Prior to an attack, the data may be used by medical planners to augment the requirements for conventional combat as appropriate for the nuclear situation. The tables can be used to prepare estimates of the number of patients at all echelons.

[D-3]

c. After an attack, the effectiveness and adequacy of the medical support effort during the first 24 hours are critical. Commanders should be informed rapidly of the estimated medical load in order to provide rescue and treatment resources or request assistance from higher headquarters, adjacent units, or allied units. These estimates should be updated postattack based on aerial or ground reconnaissance and survey.

d. In addition to casualties, a nuclear weapon detonation can generate an EMP that may cause catastrophic failures of electronic equipment components and may adversely affect the capability of all units in the area of the detonation. Electromagnetic pulse has no direct effect on personnel and is not further addressed in this publication.

#### D-5. Triage

Since a nuclear detonation may produce mass casualties, plans for a triage system must be in place. Paragraphs 3.4 through 3.5 of the guide describe patient categories by injury severity and may be used to estimate the number and injury severity of patients for a particular operational scenario. The guide does not, however, provide estimates of the number of patients by triage classification.

#### D-6. Evacuation

a. An efficient and flexible evacuation plan is absolutely essential for the preservation of life and to retain the mobility of forward medical resources. In a potential mass casualty situation, the full range of evacuation assets should be considered.

b. The extended hospital time of nuclear casualties will influence levels of evacuation or hospitalization. In addition, estimates of the different types of casualties can be a consideration in evacuation planning. In planning for evacuation, estimates provided in the guide can be used as a starting point from which to estimate evacuation resources.

#### D-7. In-Unit Care

a. Some personnel within the military unit may not be classified medically as casualties, but will require some self-aid and buddy aid. A casualty is defined as anyone entering the medical system. Paragraph 2.5 of the guide further describes the basis for casualty calculation.

b. Nuclear detonations will produce a large number of blast, burn, and projectile injuries that initially must be treated by individual soldiers trained in first aid procedures. The physical damage to the surrounding area as a result of a nuclear detonation will increase delays in medical assistance and evacuation. Training in self-aid/buddy aid will improve casualty survival rates and conserve medical resources. The guide can be used to provide a conservative estimate of the numbers of injured that will require first aid. The tables in Sections 4 through 10 of the guide, showing the status of unit personnel by time period, can be used to indicate the numbers of personnel who are injured (but not casualties) who may require first aid.

[D-4]

#### D-8. Hospital Bed Requirements

The data provided in the guide can be used to determine immediate additional bed requirements resulting from a nuclear detonation. In addition to the numbers of patients who will need beds, the data provided in the guide can also indicate the increased hospitalization time of nuclear casualties. Long-term bed requirements, greater than 30 days, are not provided. Based on the theater evacuation policy specified for the operation, the hospital bed days may be in theater or in CONUS.

#### D-9. Medical Logistics

The data provided in the guide can assist in estimating the needed supplies. The supply system must be prepared for increased demands for certain types of medical and general supplies and equipment, kits, dressings, and antibiotics. The treatment of combined injuries will not require any special types of supplies, although demands for certain types of supplies will increase.

#### D-10. Medical Force Planning

The assignment of medical support is normally based upon the total military population and the expected conventional casualty rate. The data provided in the guide may be used to assess the requirement for additional medical units. The planning guidance presented in this document can (and should) be modified to reflect the needs of the anticipated operation, including operational tempo, national/coalition priorities, medical resource allotment, and so forth. When trying to augment personnel, consider that the use of a nuclear weapon in a tactical situation could be an indication of an increased tempo of warfare. Therefore, even though a unit may be targeted with a nuclear detonation, that unit may not be the site where the highest numbers of casualties are being produced, and another unit may have priority of support.

This Section Implements STANAG 2476.

### Section III. MEDICAL PLANNING GUIDE FOR THE ESTIMATION OF NUCLEAR, BIOLOGICAL, AND CHEMICAL BATTLE CASUALTIES (BIOLOGICAL)—AMedP-8(A), VOLUME II

#### D-11. General

The guide, AMedP-8(A), Volume II, provides estimates of casualties, and remaining operational strength, after single BW attacks on tactically deployed, brigade-sized land force units, offshore naval and marine forces, and selected strategic targets in rear areas. These worst-case casualty estimates are for personnel [D-5] within both the targeted and the downwind hazard areas of the attacked forces. They assume that all affected personnel will be unsheltered and unwarned. To further estimate worst-case outcomes, the guide assumes that exposed individuals have not been vaccinated against any of the evaluated agents, nor have they undergone any type of medical prophylactic treatment prior to exposure. The tables included in the guide are designed to show numbers of expected casualties; expected fatalities; personnel at different performance levels; and times after exposure. In selected scenarios, the guide provides a method for estimating casualties among collocated civilians based on local population density.

a. The guide presents casualty estimates for all possible combinations of the following conditions:

- Eleven operational scenarios.
- Seven biological agents.
- Four types of delivery systems.
- Three attack intensities.

b. The guide is subject to limitations of extent and content. Since there are many more possible attack variables than those considered, the guide presents a limited number of estimates and provisional guidance for estimating cases not modeled. These estimates are based upon the best available medical data, but such data result in qualified estimates. Therefore, for more authoritative medical descriptions, medical planners and staff personnel should use FM 8-9, NATO Handbook on the Medical Aspects of NBC Defensive Operations, AMedP-6(B), Part II—Biological. Users of the guide must amplify or modify these estimates to meet emergent requirements such as injuries resulting from combined biological and conventional attacks.

c. Computer models that integrate available information have been used to predict the effects of future biological attacks. These resultant estimates may include substantial uncertainties when applied to specific situations. However, they provide the best estimates available to date.

d. The guide is also organized into 10 sections. Section 1 introduces features of the guide, and then presents background and medical planning considerations. Section 2 provides information on the methodology used to develop the estimates. Section 3 describes how to use the tables presented in the guide. Sections 4 through 10 of the guide contain tables of casualty estimates, with one section for each of the seven biological agents.

e. Biological attacks are likely to have a significant impact on the medical system. As detailed elsewhere in the guide, victims may number in the hundreds or even thousands. Demand for medical care may quickly overwhelm available resources; this problem will be exacerbated if medical personnel themselves become victims of the attack. Local civilian populations will be victimized as well, limiting host-nation support and potentially adding to the demands on the military medical system.

f. A variety of medical responses to BW attacks are available, depending on the agent used and whether medical countermeasures are employed prior to attack or after exposure has already occurred. [D-6] For many agents, immunization or pre-exposure prophylaxis with antibiotics may prevent illness in those subsequently exposed. After exposure, disease can often be prevented or ameliorated via immunization and therapeutic use of antibiotics, antiviral drugs, and hyperimmune gammaglobulins.

#### D-12. Medical Planning Considerations

a. Effective mass casualty management requires careful planning. The guide is designed to support such planning by providing medical planners and staff personnel with a systematic means for estimating the number of biological casualties. However, casualty management also involves practice of self-aid and buddy aid, on-site triage and emergency care, decontamination, transport to medical facilities, infection control measures, communications, health services, logistics, and evacuation by ground or air transportation.

b. Medical requirements resulting from attacks with biological agents may be substantially different from those resulting from conventional, nuclear, or chemical combat. There would be no indication of the presence of biological agents in most tactical situations. Units downwind from an attack area may be unexpectedly exposed to biological agents. In some cases, there will also be a risk of secondary infection and subsequent epidemics amongst troops and/or the local population. Additionally, use of biological agents may generate reservoirs within the local animal population that may serve as a further source of infection.

c. Often the first indication of an attack with a biological agent will be the development of symptoms in exposed personnel. Diagnosis and treatment are complicated by the fact that many of the agent-induced diseases described in the guide begin with symptoms associated with common illnesses, such as influenza. In such cases, biological agent attacks may generally be distinguished from naturally occurring epidemics by the sudden onset of disease, the large number of personnel presenting with similar symptoms, and the concentration of those personnel in geographically contaminated areas.

#### D-13. Triage

a. Since a biological attack may produce mass casualties, preparations for a triage system should be in place before the attack. Paragraph 3.3.8 of the guide describes patient categories by illness severity. For a particular described operational scenario, this information may be used to estimate the number of patients with specified levels of illness. The guide does not provide estimates of the number of patients by triage classification or usual medical descriptions.

b. Decontamination of patients must be considered before further evacuation.

#### D-14. Evacuation

a. An efficient and flexible evacuation plan is essential for adequate casualty treatment and to retain mobility of forward medical resources. For an assessment of a potential mass casualty situation, the medical planner should consider the full range of evacuation assets, limitations, and obstacles. After an [D-7] attack, the medical staff may need to estimate the number of casualties that could require evacuation at given postexposure times.

b. Evacuation requirements will vary with the type of biological agent used. Casualties resulting from some agents may not be evacuated because the time course of effects is relatively short. For others, like botulinum toxin, casualties may require evacuation to a facility where they can receive care for weeks or even months. Estimates provided in the guide can be used as a starting point from which to plan for evacuation resources, including those required for decontamination of personnel and transportation assets.

#### D-15. In-Unit Care

The casualty estimates in the guide are presented without allowance for in-unit care. However, there may be need for rapid intervention. Delays in obtaining medical care may occur because of physical damage or contamination of the surrounding area. Soldiers trained in first aid procedures may be the first to provide aid to biological agent casualties. The guide provides a conservative estimate of the numbers of exposed personnel who will require first aid. The tables described in paragraphs 3.3.2 through 3.3.4 of the guide give the time courses of effects that may apply to estimation of in-unit care and delayed medical requirements.

#### D-16. Patient Bed Requirements

Bed requirements can be estimated using the tables described in paragraphs 3.3.2 through 3.3.4 of the guide. The latter type of table is useful after an attack since it shows gains and losses of casualties over time. The type of table described in paragraph 3.3.5 of the guide may be more useful for long-range planning. It shows maximum numbers of personnel by illness severity category. The tables in the guide only provide estimates for the first 35 days after attack. Based on the theater evacuation policy specified for the operation, hospital days may be in theater or in the national area.

#### D-17. Medical Logistics

a. The estimates provided in the guide are intended to support projections of medical materiel and logistical requirements. Increased demands may occur for certain types of medical and general supplies, including equipment, kits, antibiotics, disinfectants, and other critical medical materiel. Demands may also increase for items unique to the prevention and treatment of biological agent casualties, such as vaccines, antibiotics, and antisera, as well as items adapted to contaminated environments. Tables showing maximum numbers of personnel by illness severity category can provide useful input for logistical planning.

b. Often the first indication of an attack with a biological agent will be the development of symptoms in exposed personnel. Diagnosis and treatment are complicated by the fact that many of the agent-induced diseases described in the guide begin with symptoms associated with common illnesses, such as influenza. In such cases, biological agent attacks may generally be distinguished from naturally occurring diseases.

[D-8]

#### D-18. Medical Force Planning

a. The assignment of medical support is normally based upon the total military population and the expected conventional casually rate. The guide may be used to assess requirements for additional medical units.

b. Although a specific unit may be the target of a biological attack, more casualties could be suffered by other units downwind. Accordingly, a unit other than the targeted one may have priority for support. The tables presented in the guide can be used in planning for either situation. Some tables show estimated maximum numbers of personnel by illness severity category. Such estimates should be combined with a comprehensive array of other available information to increase the effectiveness of medical force planning.

This Section Implements STANAG 2477.

### Section IV. MEDICAL PLANNING GUIDE FOR THE ESTIMATION OF NUCLEAR, BIOLOGICAL, AND CHEMICAL BATTLE CASUALTIES (CHEMICAL)—AMedP-8(A), VOLUME III

#### D-19. General

a. The primary purpose of Volume III is to assist medical planners, logisticians, and staff officers in predicting CW contingency requirements. Requirements include medical personnel, medical materiel stockpiles, patient transport or evacuation capabilities, and facilities needed for patient decontamination, triage, treatment, and supportive care. An optional purpose is to support medical operational estimates.

b. The guide provides medical worst-case estimates of casualties and remaining operational strength after a single CW attack on a tactically deployed, brigade-sized land force units, with protection available and protection unavailable. These worst-case casually estimates are for personnel located within both the targeted and the downwind hazard areas of the brigade. It is assumed that all targeted personnel will be unsheltered and without medical pre-exposure prophylactic treatment. Tables in the guide are designed to show total numbers of—

- Casualties with different types and severities of injury at various times after exposure.
- Personnel at different performance levels and times after exposure.
- Fatalities at specified times after exposure.

[D-9]

c. The guide presents estimates of personnel status at specific time points. These range from 1 to 3 hours to 7 to 30 days after an attack, depending on the type of agent considered. Such estimates are projected from all possible combinations of the following conditions:

- Seven operational scenarios involving three types of units: heavy brigade, support brigade, and light infantry brigade.
- Three chemical agents: the nerve agents GB and VX, and the blister agent HD.
- Three types of munitions delivering the agents: aerial bombs, tactical ballistic missiles, and rounds from multiple launch rocket systems/artillery batteries—

- Three attack intensities for each type of munition: light, moderate, and heavy.
- Two postures of individual physical protection against the attacks: unavailable and available.

d. An index to essential information and four sample problems to illustrate use of this information are at the end of the guide (see Section 11). Section 11 provides a planning guide overview, describes applications, and presents a brief explanation of modeling methods used to prepare estimates.

e. The guide is subject to limitations of extent and content. Since there are many more possible attack variables than those considered, the guide presents a limited number of estimates. These estimates are based upon the best available toxicological values, but such values are qualified estimates. Therefore, medical planners and staff personnel should use FM 8-9, NATO Handbook on the Medical Aspects of NBC Defensive Operations, AMedP-6 (B), Part III—Chemical, for more authoritative medical descriptions and information on effects of longer duration.

f. The guide is most value to the user who needs to know what kinds of casualties to expect, relative numbers of each, and the time frames in which they are likely to appear. To assist the user, who lacks experience in actual CW, the guide describes types of injury, relevant factors, general magnitudes of effects, and effects of time courses on chemical casualty numbers. The casualty estimates are appropriate for training exercises. However, this initial attempt to provide complex estimates has limitations for battlefield use. The limitations are described as follows:

- The guide provides estimates for a few of many possible chemical attacks. Each estimate is based upon computer modeling of the consequences of specified conditions. This is like saying that the numbers of men who sneeze, after inhaling an allergic flower pollen, might be predicted if specific information (EXAMPLE: The wind speed and direction, the current weather, altitude, time of day, and sites of concentrated flower growth) is known for the specific geographic location of a particular brigade on a given mountain. If such estimates are made for a few widely different mountains, a user of the estimates may be able to guess the numbers of sneezing men in his own brigade, located on a separate mountain. However, if the conditions on both mountains are not nearly identical, the user will need to estimate a scaling factor and apply it to adjust the number predicted for a different environment.
- [D-10] It is unlikely that exactly identical conditions will exist for any two mountains or chemical attacks. The user of the guide must decide which scenario best represents his conditions (or interpolate from two scenarios), then use or adjust the estimates. Therefore, each user must recognize any differences from modeled conditions that might require him to increase, or decrease, an estimate. The user may need to apply a commander's guidance on acceptable risk levels, or consider restrictions of available resources, before accepting, interpreting, or modifying the relevant planning guide numbers. The most difficult problem for the user will be to determine how much to increase, or decrease, planning guide numbers to fit the user's situation. This problem is discussed in paragraph 3.4 of the guide.
- The user should be aware that medical worst-case targeting selects for maximal numbers of survivors entering the medical system, not for maximal operational losses. The tabulated estimates are very highly sensitive to the degree of clustering of personnel and their assumed location within a standardized brigade area. Accordingly, use of this targeting method leads to large variations that are based upon the probabilities of hitting clustered personnel, not evenly or widely distributed personnel. Therefore, these estimates do not provide a good basis for estimating the most likely outcomes for a series of "average" attacks, or for comparing a scenario with an actual attack. Although the tabular format of the guide suggests that the listed numbers are exact, the user should understand that different targeting could readily produce other numbers. Selection of a scaling factor Is discussed in paragraph 3.4 of the guide.

#### D-20. Medical Planning Considerations

a. The guide provides medical planners and staff personnel with a systematic means for estimating chemical casualties in various-sized units, without regard to composition. This document provides more accurate and detailed estimates and is based upon detailed operational scenarios for brigade-sized units. Both chemical planning guides support estimates of combat performance from individuals remaining in the unit.

b. Effective mass casualty management requires careful planning. The guide is designed to support such planning by providing medical planners and staff personnel with a systematic means for estimating the number, type, and time-related status of chemical casualties.

NOTE

Each user is advised to consult any available national military NBC defense doctrinal publications of similar nature.

c. Medical requirements during CW may be substantially different from those for the usual combat situation. There may be no indication of the presence of chemical agents in some tactical situations. Unprotected units downwind from an attack area, or those entering contaminated areas in an unprotected posture, may be unexpectedly exposed to chemical agents. However, casualty management also involves practice of self-aid and buddy aid, on-site medical triage and emergency care, transport to medical facilities, communications, health services, logistics, and evacuation by ground or air transportation.

[D-11]

d. The signs and symptoms of chemical agent exposure may be sudden and intense, or delayed and subtle, depending on the agent used and the level of exposure. Individuals may not reach the first level of care for 15 to 60 minutes after the onset of effects. Decontamination may delay medical treatment. Stabilization should occur before casualties leave emergency care areas, but contamination of these areas may delay the stabilization process. However, effects of decontamination or secondary contamination on estimated doses and effects are not considered in the guide. For medical planning, users of the guide need to consider the various qualifications of its casualty estimates, as discussed in paragraphs 3.4 and 3.4.2 of the guide.

e. A chemical burn caused by HD can require more care than a same-sized burn induced by conventional munitions. Therefore, the initial prognosis may require revision after treatment is underway, and estimates of percent capable by performance band may require adjustment.

#### D-21. Triage

Since a chemical attack may produce mass casualties, preparations for a triage system should be in place before the attack. Paragraph 2.5.1 of the guide describes patient categories by injury severity. For a particular described operational scenario, this information may be used to estimate the number of patients with specified levels of injury. The guide does not provide estimates of the number of patients by triage classification or usual medical and toxicological descriptions.

#### D-22. Evacuation

a. An efficient and flexible evacuation plan is essential for adequate casualty treatment and to retain mobility of forward medical resources. For assessment of a potential mass casualty situation, the full range of evacuation assets, limitations, and obstacles should be considered by the medical planner. After an attack, the medical staff may need to estimate the number of casualties that require evacuation resources at given postexposure times.

b. Evacuation requirements will vary with the type of chemical agent used. Nerve agent casualties may not be evacuated because the time course of severe effects is relatively short. Depending upon exposure conditions, HD casualties may or may not require evacuation to a facility where they can receive care for several days, or possibly 6 to 9 months. Estimates provided in the guide can be used as a starting point from which to plan for evacuation resources.

#### D-23. In-Unit Care

The casualty estimates in the guide are presented with no allowance for in-unit care such as self-aid or buddy aid. Soldiers trained in first aid procedures may be the first to see chemical injuries. The guide can provide an estimate of the numbers of injured personnel who will require first aid. However, there may be need for rapid augmentation, support, or other intervention. Delays in obtaining medical care may occur because of physical damage or contamination of the surrounding area. The tables described in paragraphs [D-12] 3.3.2 and 3.3.3 of the guide give the time courses of effects that may apply to estimation of in-unit and delayed medical requirements.

#### D-24. Patient Bed Requirements

Requirements for patient beds and hospitalization time may be greater after chemical exposures than after a conventional attack. Such increases are particularly important for agents, such as HD, that produce injuries followed by a long recovery period. Bed requirements can be estimated using the tables described in paragraphs 3.3.2 and 3.3.3 of the guide. Casualties Occurring by Time Period tables (see paragraph 3.3.3) in the guide are useful after an attack since they show gains and losses of casualties over time. Personnel by Injury Category tables (as described in paragraph 3.3.4) in the guide may be more useful in long-range planning. They show maximum numbers of personnel by injury severity category. The tables in the guide only provide estimates for the first 30 days after attack. Depending upon the theater evacuation policy specified for the operation, hospital days may be either in theater or in the national area.

#### D-25. Medical Logistics

The estimates provided in the guide are intended to support projections of medical materiel and logistical requirements. Increased demands may occur for certain types of medical and general supplies. These may include specific equipment, kits, dressings, antibiotics, and other critical medical materiel. Demands may also increase for items unique to the chemical battlefield (such as nerve agent antidote autoinjectors), as well as items adapted to chemical environments (including IV systems and special self-contained intensive care units). Tables showing maximum numbers of personnel by injury severity category (see paragraph 3.3.4 in the guide) can provide useful input for logistical planning.

#### D-26. Medical Force Planning

a. The assignment of medical support is normally based upon the total military population and the expected conventional casualty rate. The guide may be used to assess requirements for additional medical units. The use of chemical weapons in tactical situations could be one indication of an increased tempo of warfare and need for additional personnel.

b. Although a unit may be targeted for chemical attack, that unit might not be located where the highest number of casualties could occur (as in a downwind hazard area). Accordingly, another unit might have priority for support. The tables presented in the guide can be used in planning for either situation. Some tables (see paragraph 3.3.4 in the guide) show estimated maximum numbers of personnel by injury severity category. Such estimates should be combined with a comprehensive array of other available information to increase the effectiveness of medical force planning.

c. The guide is organized into 11 sections. Section 1 introduces the guide and presents background and medical planning considerations. Section 2 provides information on the methodology used to develop the estimates of fatalities, casualties, and effectiveness of individuals remaining in the unit. [D-13] Section 3 explores the use of the casualty prediction tables based on combat effectiveness decrements and estimates of the number of casualties categorized by insult level. Sections 4 through 10 contain tables of casualty estimates. Section 11 is a tutorial on use of the tool.

d. These medical worst-case casualty estimates (see paragraph 2.1.2 through 2.1.7 in the guide) are for personnel in the chemical-targeted and downwind hazard areas of the brigade sector. The actual areas presenting chemical agent hazards to personnel are relatively small and localized when compared to the entire brigade sector. These estimates are not valid for acute effects from repeated exposures, possible delayed effects of low dosage exposures, operational worst-case targeting, targets with different numbers or distributions of exposed personnel, or attacks involving different conditions (of meteorology, terrain, protective status, and so forth) than are modeled. Although the guide is primarily designed to support medical force planning for future CW defense, it may be used to anticipate short-term requirements. For example, delayed requirements of HD victims for care or evacuation resources may be predicted from tables that give estimates of casually numbers by injury type at given times after a CW attack (see paragraphs 3.3.2 and 3.3.3 in the guide).

## APPENDIX F
EMPLOYMENT OF CHEMICAL AND BIOLOGICAL COLLECTIVE PROTECTION SHELTER SYSTEMS BY MEDICAL UNITS

### Section I. INTRODUCTION

#### F-1. General

To continue the HSS mission under CB conditions, MTFs must search out contamination free areas or employ CPS systems. Levels I and II MTFs may be able to locate contamination free areas; however, due to the mobility limitations of hospitals, they must always be prepared to operate under CB conditions if the area is under attack. Systems that can be employed as an MTF (Levels I, II, III, and IV) are described in this appendix.

#### F-2. Types of Collective Protection Shelter Systems

a. The CBPS system is employed at the BAS, DCS, and FST. The CBPS is attached to the hard-walled box on the rear of a high mobility multi-purpose wheeled vehicle (HMMWV). The BAS will have one CBPS system per treatment team; the DCS will have four CBPS systems; the FST will have three CBPS systems. Also, systems will be issued to other selected medical treatment teams. When employed at the DCS, the patient holding team will also require GP tents to hold their required number of patients (see Chapter 4). Patients held inside the CBPS will be those that have been decontaminated and admitted into the system for treatment and are recovering from the treatment procedures and are awaiting evacuation. Any patients held in the GP tent must remain in MOPP Level 4 (the GP tent will not have collective protection); these patients are those that are expected to RTD within 72 hours.

NOTES

1. Normally, patients will not be held at the DCS under NBC conditions unless evacuation cannot be accomplished. They should be RTD or evacuated to a clean MTF, as soon as the mission permits.

2. The CBPS can also be employed as the DCS in the conventional mode. Employment in either mode still requires GP tentage for patient holding to meet total patient holding requirements.

b. The DEPMEDS-equipped patient care areas of the US Army Force XXI hospital and the hospital unit base (HUB) of the Medical Force 2000 (MF2K) will employ the CP DEPMEDS. It will not protect personnel or patients from the thermal, blast, and initial radiation effects of nuclear weapons; however, it will provide some protection against fallout effects. Areas of the hospital that are not included in the chemically protected (CP) DEPMEDS are MF2K general hospital unit medical (HUM), MF2K field hospital unit holding (HUH), MF2K combat support and general hospital unit surgical (HUS), minimum care wards, administrative areas, food service, supply (including Class VIII), and staff quarters. The system includes—

[F-2]

- Chemically/biologically protected liners for tent, expandable, modular, personnel (TEMPER) and passageways.
- CB-filtered and conditioned (heated or cooled) air (field deployable environmental control unit [FDECU] or H80 Army Standard Heater).
- Chemically/biologically protected ambulatory, litter, and supply air locks.
- Chemically/biologically protected latrines.
- Chemically/biologically protected seals for ISO shelters.
- Chemically/biologically protected water supply system.

c. The M20 simplified collective protection system is another system that is available. It consists of a chemically protected room liner, a CB filter blower, and an ambulatory air lock. However, it does not have a litter air lock making it unsuitable for litter patient care. The M20 may be used to protect medical staffs at the DCS, FST, and hospitals, patients held in the GP tents at the DCS and in the minimum care wards and staff quarters of the hospitals. Thus providing additional CB protection for staffs and patients.

### Section II. EMPLOYMENT OF THE CHEMICALLY BIOLOGICALLY PROTECTED SHELTER SYSTEM

#### F-3. Establish a Battalion Aid Station in a Chemically Biologically Protected Shelter

To establish a BAS in a CBPS, use one CBPS per treatment team for conventional operations in a split-team mode. When operating in a squad configuration and in the conventional mode, the two CBPS systems may be complexed to provide more workspace. However, keep in mind that the treatment squad is not staffed to operate the two systems in the CB mode. Therefore, when the two systems are complexed and the treatment squad must convert and operate in the CB mode, they may want to close the complexing door and only use one system. When initially setting up the CBPS for operations in the CB mode, only one CBPS is setup; see Note 2 below. Set up the system as described in TM 10-5410-228-10. To be operational as a BAS, set up medical supplies and equipment as required or as designated in the TSOP. A PDS consisting of a contaminated ambulance point, contaminated triage point, a patient decontamination area, and a contaminated treatment area is established on the downwind (prevailing wind) side of the CBPS. An overhead cover of plastic sheeting (approximately 20 feet wide by 50 feet long) is set up over the PDS, the hot line, and the clean treatment/waiting area; the cover overlaps the air locks. The clean treatment/waiting area should have an area at least 20 feet wide by 15 feet long to allow space for placing patients into the litter air lock without crossing the hot line. A second area covered with 20 × 25 feet of plastic sheeting (the evacuation holding area) is set up beside the shelter on the opposite side from the generator. The clean treatment area is separated from the decontamination area by a hot line with a shuffle pit. Only clean [F-3] (decontaminated) patients or personnel are allowed to cross the hot line into the clean treatment area, or are admitted into the CBPS. Figure F-1 presents one layout of a BAS using the CBPS. See TM 10-5410-228-10 for complete details on setting up, operating, and maintaining the CBPS. Each CBPS provides 300 square feet of work area.

NOTES

1. The overhead cover is not needed when the wind speed exceeds 10 knots per hour. The plastic will not stay in place.

2. Although each treatment team of the BAS has a CBPS; only one system is set up when operating in the CB mode. This is due to the lack of authorized personnel to operate all systems at one time in the CB mode. Eight medical personnel are required to operate the BAS (employing one CBPS) in the CB mode. At least eight nonmedical personnel are required to perform patient decontamination under medical supervision. Also, only setting up one system in the CB mode provides the BAS the ability to retain its flexibility in order to maintain its support mission of being where it is needed and when it is needed. The CBPS can be used as the treatment shelter in the conventional mode as well. When the treatment squad is operating in the split-team mode, each team will have a CBPS for use as its treatment shelter. When operating one system in the CB mode, the other system provides a replacement in the event the one in use in the CB mode is damaged beyond repair. This ensures continued HSS to the command.

[F-4]

Figure F-1. Battalion aid station using the chemically biologically protected shelter.

#### F-4. Division Clearing Station in a Chemically Biologically Protected Shelter

To establish a DCS using the CBPS, set up four shelters as described in the TM. To be operational, medical supplies and equipment are set up as outlined in the unit TSOP. The four shelters are complexed as shown in Figure F-2. With four CBPS systems set up and operational, a total of 1,200 square feet of work area is available. The contaminated triage, decontamination, and contaminated treatment areas are separated from the clean treatment/waiting area by a hot line with a shuffle pit. Overhead covering is provided as described for the BAS. Patients are admitted through the EMT litter or ambulatory air lock. Patients are released through the patient holding air locks. This aids in controlling entry and exits; thus preventing the introduction of contamination into the systems. At least eight nonmedical personnel from supported units are required to perform patient decontamination under medical supervision at the DCS.

[F-5]

NOTE

In the event that the overpressure system fails on a system that is in use with entry/exit air locks, move to the available shelter with an entry/exit air lock in the same direction for use as the entry/exit until the failed system can be restored. Example 1: At the DCS the EMT system fails, move to the ATM shelter to receive patients until the EMT system has been restored. Example 2: At the DCS the patient hold system fails, move exits to the dental/lab/x-ray shelter until the patient hold system can be restored. Example 3: At the FST the postoperative system fails, use the preoperative shelter until the postoperative system can be restored. These options will allow patient care operations to continue until the failed systems can be restored.

Figure F-2. Chemically biologically protected shelter configuration as a division clearing station.

[F-6]

#### F-5. Forward Surgical Team in a Chemically Biologically Protected Shelter

To establish a FST using the CBPSs, follow the procedures for the DCS except set up three CBPSs. All equipment is set up inside the CBPS as required by your unit TSOP. With three CBPSs set up and operational, a total of 900 square feet of work area is available (Figure F-3). When the FST is forward in support of a medical company and operating in the CB mode, the FST systems are connected to the DCS of the supported medical company. Figure F-4 shows the FST and DCS connected. When operating in the CB mode with the medical company, all patients are received through the EMT air lock of the DCS. The patients are triaged in the DCS and, based upon their injuries, they are routed to the DCS treatment area or to the FST for surgical care. Patients released from the FST for evacuation are placed in a PPW and processed through the litter air lock in the FST recovery section. Patient decontamination is performed at the PDS operated by the DCS. The FST cannot operate in a CB environment without being complexed with the DCS. They do not have any patient decontamination capabilities.

[F-8]

### Section III. EMPLOYMENT OF THE CHEMICALLY PROTECTED DEPLOYABLE MEDICAL SYSTEMS AND SIMPLIFIED COLLECTIVE PROTECTION SYSTEMS

#### F-6. Collective Protection in a Deployable Medical System-Equipped Hospital

a. When the threat of NBC action is anticipated in the AO, the CP DEPMEDS components must be set up as the hospital is being established. The system cannot be set up in a hospital that has already been established; to do so requires the hospital to be closed, all TEMPERs be struck, and erected with the M28 liners installed during the erection process. To establish CPS in a DEPMEDS-equipped hospital, follow the procedures as described in TM 10-5410-283-14&P. Training Circular 8-13 provides instructions on establishing a US Army DEPMEDS-equipped hospital (without CPS). Figure F-5 presents one layout of the DEPMEDS-equipped patient care area of a MF2K CSH HUB employing the CP DEPMEDS with an internal water supply system. Figure F-6 presents a layout of the patient care area of the DEPMEDS-equipped portion of an 84-bed MRI hospital. Figure F-7 presents a layout of the patient care area of the DEPMEDS-equipped portion of a 164-bed MRI hospital.

b. When employing CP DEPMEDS, provisions for waste disposal and protected water and food supplies within the system are established. Additionally, Class VIII supplies must be protected from contamination. Supplies not in use or needed in the protected operational areas are stored in medical chests, shipping containers, or wrapped in layers of plastic that are inside covered areas, such as closed MILVANs or tents. When contamination is present, only open these storage areas for operational area emergency resupply. Use plastic sheeting or other leak-proof material to provide an additional barrier between the supplies and the contamination. Wrap supplies in plastic or other barrier material for movement from the storage area to the resupply air lock of the CP DEPMEDS.

- A water supply system with distribution hoses is established inside the CP DEPMEDS areas (Figure F-5). Pumps continuously circulate the water from the storage tank through the hose system back to the storage tank. The continuous circulation ensures that the chlorine residual is maintained in the water supply. Personnel in areas that are not included in the continuous flow system must draw water from the system and carry it to their work areas in 5-gallon water cans or other containers. Water resupply is accomplished by passing a hose through the utility port at the end of the TEMPER and M28 liner for a connection to the water transport vehicle. The ends of both hoses must be decontaminated with a 5 percent chlorine solution before connecting them together. The vehicle must have a tank or water supply container that is NBC protected to ensure that the water supplied is free of NBC contamination.
- Rations, as determined by the hospital commander, should be available within the protected area for personnel and patients. Under emergency conditions the commander can authorize feeding patients MRE rations for limited periods of time (up to 72 hours), if they are able to chew and swallow. However, attempts must be made to ensure the required types of rations for patient feeding are available in the CPS. The rations can be stored in any available space; however, the rations must be protected from exposure to possible contaminants, especially liquids. Ration control measures are established to ensure that the rations are only consumed as provided for in the hospital TSOP.
- [F-9] Two CB protected latrine systems are included in the CP DEPMEDS. The latrines contain bedpan wash areas. The waste from the latrines is collected in an outside receiving container. The waste is removed from the container and disposed of as outlined in the unit TSOP.
- Solid waste (including medical) must be placed in plastic bags. Seal the top of the bags to prevent spillage, odors, or spread of infections/disease. NEVER overfill the bags; always leave enough room in the bag to make a good seal. Place the sealed bags in the supply air lock. Inside personnel close the inner door to the air lock. Outside personnel check to ensure that the inner air lock door is closed before opening the outside door. Remove the bags and take them to the designated waste collection/disposal site. Disposal may be by burial on site or by transport to a designated disposal facility. Transport may be by organic vehicles or contractor support vehicles. The specific technique for disposal will be outlined in the unit TSOP.
- All liquid waste produced within the CP DEPMEDS is collected through a piped liquid waste system to a central collection container. The waste container for the latrines may be used to collect the liquid waste from the operational areas of the CP DEPMEDS. The container is emptied and the waste disposed of as outlined in the unit TSOP.

[F-11]

Figure F-7. Sample layout of a 164-bed medical reengineering hospital employing chemically protected deployable medical system.

#### F-7. Chemically/Biologically Protecting the International Organization for Standardization Shelter

To chemically/biologically protect the ISO shelters, seal all seams and openings of the ISO to prevent the entry of CB agents. The seals connecting the various sides and floor of the shelter may be a CB protected material; thus providing a seal to the shelter. When the seals are not of a CB protected material, the seams [F-12] must be taped to provide a CB protected barrier over the soft seals. Any openings not being used for introduction of support power lines, water lines or waste water lines must be sealed to prevent entry of CB agents. All access panels must be securely closed to prevent entry of vapors.

#### F-8. Chemically/Biologically Protecting the Vestibules

The vestibules connect TEMPERs to TEMPERs, ISOs to ISOs, and ISOs and TEMPERs. To harden the vestibules, install the CB liners inside and fasten the ends to the liners of the TEMPER or to the doors of the ISOs. Vestibule liner connectors are provided for use at the entry of each ISO.

#### F-9. Chemically/Biologically Protecting Air Handler Equipment

a. The FDECU is chemically/biologically protected. The system can be operated without the CB filters. When required to operate in the CB mode, the fresh air intake on the FDECU is closed and the CB filter blower is turned on drawing fresh air through the filters to support the FDECU and to provide clean air for the CPS. Additionally, recirculation filters are placed within the shelter system to remove any agent that may have entered through any of the entry/exit areas or through breaches in the shelter system.

b. When heaters are required, they must be chemically/biologically protected to prevent entry of contamination. The CB filter units are connected to the fresh air intake side of the heater and the heated air discharge side of the heater is connected to the air supply of the TEMPER/ISO.

#### F-10. Establish Collective Protection Shelter Using the M20 Simplified Collective Protection System

The M20 is used to establish a CPS within a room of opportunity, or inside a tent; however, the available space will be limited by tent poles and other components of the tent. Currently this system only provides ambient temperature air. See the TM and manufacturer's publication provided with the system and system components for details.

NOTE

The M20 does not have a litter air lock. Only staff or ambulatory patients can enter. See the TM provided with the system for setup procedures.

#### F-11. Casualty Decontamination

Patients admitted into the MTF must be contamination free. Therefore, a casualty decontamination area must be established near the MTF. The casualty decontamination area should be provided with an overhead cover as described for the CBPS system, except that it does not overlap the entry to the hospital. Also, [F-13] consideration must be given to the location of other operations at the hospital site when establishing the casualty decontamination area. However, the area must be close enough to the entry/exit of the CPS to protect the patients from the environment and reduce their exposure to recontamination. Keep in mind that under NBC conditions personnel outside of the CPS are at MOPP Level 4 (except decontaminated patients; they have their mask on), thus increasing the stress load and reducing their overall performance capabilities. The entry/exit area must have overhead cover to protect patients awaiting access to the CPS. See Appendix I for setting up a casualty decontamination area and for decontamination procedures.

### Section IV. OPERATIONS, ENTRY, AND EXIT GUIDELINES

#### F-12. Operations

These operations, entry, and exit guidelines may be used to prepare a unit SOP for the operation of CPS systems in your unit.

a. When using these guidelines, the following should be considered:

- Location of the shelter (flat, hilly, rocky ground).
- General climate of the AO (high and low temperature variations during operation).

b. Information on setting up, striking, and operating the CPS is contained in the equipment publications. Where applicable, special procedures are provided in these publications for setting up in both clean and CB vapor hazard areas. However, the CP DEPMEDS is NOT set up in a CB vapor hazard area. The commander will determine which procedures to use.

c. During operations, periodic checks are made of the atmosphere within the shelter. These checks are made by using available chemical agent detection equipment and material to determine if chemical agent penetration has occurred. Should chemical agent penetration occur, all personnel must mask; then ensure that patients are protected until the agent has been purged from the shelter.

#### F-13. Decontamination of Entrance Area

a. Normally, the MTF will not operate in a CB vapor hazard environment. However, if the MTF must remain in an area on a temporary basis and liquid agent contamination is present, the immediate area around the entrance must be decontaminated.

b. To decontaminate the area around the entrance, use one or more of the following methods:

- Turn over about 2 inches of soil.
- [F-14] Remove the top 1-inch layer of soil containing the liquid agent. Use the CAM or M8 detector paper to check the area after the topsoil is removed to ensure complete agent removal.
- Add several inches of clean soil or sand.
- Mix STB into the top 1/2 to 1 inch of soil.
- Use DS2 on contaminated hard-surfaced areas or frozen ground.

#### F-14. Procedures Prior to Entry

All personnel (staff and patients) must be decontaminated before they are permitted entry into the CPS.

- Use chemical detection equipment to check for the presence of contamination on individuals and their equipment; also check for presence of contamination on individual weapons if they are allowed in the CPS. Normally, weapons will not be allowed in the patient care areas, but will be stored outside near the entry/exit. Thorough decontamination is critical in preventing contamination transfer into the CPS.
- When a chemical agent is detected, follow the procedures in Appendix C for patient decontamination and FM 3-5 for other personnel decontamination before entering the CPS. All contaminated clothing and equipment are placed in the contaminated dump. Weapons should not have been evacuated with patients. However, if weapons are evacuated with the patient, they are decontaminated and held by the MTF (administrative personnel or hospital supply) for disposition instructions.
- Decontamination must be thorough; procedures must be strictly followed. Failure to do so can contaminate the interior of the MTF and injure medical treatment personnel; thus reducing their mission support capabilities.

WARNINGS

1. ALWAYS PURGE THE AIR LOCK BEFORE OPENING THE INNER DOOR, IF THE OUTER DOOR HAS BEEN OPENED.

2. WHEN OPERATING IN A TOXIC ENVIRONMENT, NEVER OPEN THE OUTER AND INNER DOORS OF THE AIR LOCKS AT THE SAME TIME.

#### F-15. Entry/Exit for the Collective Protection Shelter System

a. Ambulatory Personnel.

[F-15]

(1) Entry procedures.

(a) Ambulatory patients and others remove their MOPP (except their mask), BDUs, and boots outside the air lock. This procedure reduces the amount of possible contamination entering the air lock.

(b) A check is made to ensure that the ambulatory air lock is empty and the inner door is closed.

(c) The individual enters the air lock and closes the outer door.

(d) The air lock is purged for 3 minutes. At the end of the purge cycle, the individual checks for contamination. If contaminated, the individual must return to the outside and decontaminate his skin; then return to the air lock and repeat the purge cycle and contamination check. If no contamination is detected, the protective mask is removed and placed in a plastic bag. The plastic bag is sealed and labeled. The individual opens the inner air lock door and enters the CPS; the plastic bag is carried into the shelter with the individual.

(2) Exit procedures.

(a) A check is made to ensure that the ambulatory air lock is empty and the outer door is closed.

(b) The individual enters the air lock and closes the inner door.

(c) The individual puts on his protective mask; then exits through the outer door.

(d) The individual puts on his BDU and boots then assumes the established MOPP level before departing the immediate area of the exit door.

WARNING

DO NOT OPEN THE OUTER DOOR UNTIL THE PROTECTIVE MASK HAS BEEN PUT ON.

NOTES

1. Ambulatory patients that enter the CBPS become litter patients and are placed in PPW when released because the MTF does not have replacement MOPP ensembles for patient issue.

2. Exits must be spaced so that at least a 3 minute purge of the air lock is accomplished before the inside door is opened. Only open the doors long enough to permit passage.

[F-16]

b. Litter Patients.

(1) Entry procedures.

(a) An outside aidman notifies an inside aidman that a litter patient is ready for admission.

(b) The inside aidman ensures that the inner litter air lock door is closed. The outside aidmen open the outer air lock door and place the litter on the litter rails; they push the patient into the air lock headfirst; then they close the outer door. After a purge time of 3 minutes, an aidman inside the CPS opens the inner door and checks the patient to ensure that he is contamination free. The patient is checked by placing the CAM nozzle near absorptive surfaces, such as the patient's hair. If no contamination is found, the aidman removes the patient's mask and places it in a plastic bag. The inside aidmen remove the patient from the air lock and position him on treatment litter stands, or move him to the treatment area as directed by supervisory personnel.

(c) Patients received at the treatment facility in the PPW are checked for contamination; if they are contamination free, they may be processed through the litter air lock in the PPW. The inside aidmen ensure that the inner litter air lock door is closed. The outside aidmen open the outer air lock door and place the litter on the litter rails and push the patient into the litter air lock headfirst, then close the outer door. Purge the air lock for 3 minutes. After the purge time, an aidman inside of the CPS opens the inner air lock door and uses the CAM to check the patient to ensure that he is free of contamination. If no contamination is found, the inside aidmen remove the patient from the air lock. (If the patient is wearing a protective mask, the mask is removed and placed in a plastic bag before the patient is moved from the air lock.) As the patient is removed from the air lock, the PPW is opened and rolled inside out so that any desorbing vapors are adsorbed by the charcoal layer. The inside aidmen remove the patient from the air lock and position him on litter stands. The patient is transferred to a clean litter; then moved to the treatment area as directed by supervisory personnel. The receiving litter and PPW is returned to the outside; dispose of the PPW in the contaminated waste dump. Decontaminate the litter and return it to the litter pool.

NOTE

Should contamination be found when monitoring the air lock in (b) or (c) above, repeat the purge cycle, then retest for contamination. All vapor hazards must be eliminated before the patient is moved into the CPS. Repeating the purge cycle may NOT be possible if the patient is in need of immediate lifesaving care. The patient may have to be returned to the outside treatment area for immediate care.

(2) Exit procedures.

(a) The litter patient is placed in a PPW. A battery operated blower unit with a CB filter may be attached to the PPW to provide fresh air to the patient; thus reducing the heat load on the patient and the carbon dioxide buildup inside the PPW.

[F-17]

(b) An inside aidman notifies an outside aidman that the patient is ready to exit the shelter. An outside aidman ensures that the outer air lock door is closed. The patient is placed in the litter air lock feet first. The inner air lock door is closed. The outside aidmen open the outer door and remove the patient.

(c) Hospital staff, visitors, or ambulatory patients exit through the ambulatory air lock. Before entering the air lock, each individual must ensure that the outer air lock door is closed. The individual enters the air lock and closes the inner door; puts on his protective mask and exits through the outer door. The individual puts on his BDU and boots, and then assumes the established MOPP level before departing the immediate area of the exit door.

WARNING

DO NOT OPEN THE OUTER DOOR UNTIL THE INNER DOOR HAS BEEN CLOSED.

NOTE

Exits must be spaced at least 3 minutes apart to allow for a complete purge cycle of the air lock.

#### F-16. Resupply of Protected Areas

Resupply of protected areas is accomplished by placing contamination-free supplies or equipment on a litter and passing it through the litter air lock, or processing it through the supply air lock. The litter air lock must be purged for 3 minutes. The supplies must be checked for contamination before they are removed and placed within the CPS. The supply air lock must be purged for the stated time as outlined in the supporting technical manual; usually 45 minutes. Again the supplies must be checked for contamination before they are removed and placed within the CPS.

[G-1]

## APPENDIX G
PATIENT DECONTAMINATION

### Section I. INTRODUCTION

#### G-1. General

a. Patient decontamination presents special problems for units and HSS personnel. Nuclear, biological, and chemical contaminated patients create increased hazards to rescuers and HSS personnel; thus, causing delays in providing essential first aid and medical treatment for injuries from sources other than the exposure to NBC weapons/agents. Casualty decontamination procedures are performed by each individual, as buddy aid, or at a unit decontamination station prior to the arrival of medical personnel. See FM 3-5 for procedures on individual, buddy aid, and unit decontamination. Patient decontamination procedures are normally performed at an MTF under medical supervision. Patient decontamination stations may be established (collocated) at central unit decontamination faculties, if medical support is available. However, augmentation medical support must be requested to provide patient care and supervise the patient decontamination process. Because, when the unit is undergoing decontamination operations, organic medical personnel must also decontaminate their equipment and personnel. Therefore, they are not available to provide medical support for operating the patient decontamination station that is collocated with the central unit decontamination facility.

b. The term "decontamination" as used herein means the removal or neutralization of radioactive particles, BW agents, and CW agents to levels low enough that patients may be treated without contaminating the MTF and without posing health risks to unprotected medical providers. "Decontamination" does not imply absolute removal of contaminants.

NOTE

The decontamination procedures described below are for NBC contaminated patients. These procedures may also be used for most TIM contaminated patients. However, soap and water will suffice for most TIMs; but some TIMs react with water. For those TIMs another material must be used to decontaminate patients. For detailed information on decontamination of TIM contaminated patients, see FM 8-500.

c. Physical removal of contaminants is the primary method of decontamination. Physical removal does not require vigorous scrubbing; in fact, vigorous scrubbing can force some agents deeper into the skin; thus, increasing the agent effect rather than reducing its effects. The use of a M291 skin decontaminating kit (SDK) neutralizes/reduces the effects of an agent, but physical removal is of utmost importance. When a SDK is not available, the use of soap and water should be considered as the next best method. However, the use of soap and water requires large amounts of water that may not be available because the soap must be rinsed from the skin to reduce skin irritation from the soap. An alternate skin decontaminant is a hypochlorite solution; but it should only be used when SDKs and/or sufficient quantities of water are not available. Use a 0.5 percent hypochlorite solution on the protective mask and skin. A 5 percent hypochlorite solution can be used on the mask hood, gloves, and other outer garments.

[G-2]

CAUTION

Do not use the 5 percent solution on the skin; it can cause severe skin irritation.

#### G-2. Immediate Decontamination

Decontamination must begin at the platoon and company level with the individual soldier, prior to the arrival of medical personnel. The soldier himself or members of his team must perform immediate decontamination. When the casualty's condition and the mission permits, they may go through a MOPP gear exchange at their unit before evacuation (see FM 3-5). Performing a MOPP gear exchange at the unit before evacuation will reduce the amount of contamination that can be transferred to the MEDEVAC vehicle. However, the MOPP gear exchange must not cause further injury to the casualty. First aid for CW agent must be administered; such as administering nerve agent antidotes (such as nerve agent antidotes and convulsant antidote for nerve agent [CANA]), as required. Enter the time and type of contamination on a field expedient NBC casualty card (Figure G-1). Use the CAM, M8 chemical agent detector paper, or M9 tape to determine the type of chemical contamination. Use a radiation detection meter/device to determine the level of radioactive contamination, if required. Currently, there are no BW agent detectors that can be used to check patients for BW agent contamination. Therefore, all patients suspected of being contaminated with a BW agent must be decontaminated. When medical personnel arrive, they should enter the time and type of contamination and number of antidote injections that were administered as first aid on the Department of Defense (DD) Form 1380 (Field Medical Card [FMC]).

Figure G-1. Field expedient nuclear, biological, and chemical patient card.

#### G-3. Patient Decontamination and Thorough Decontamination Collocation

a. Collocating patient and thorough decontamination operations in the BSA may provide several advantages (Figure G-2). It—

[G-3]

- Preserves the principle of limiting the spread of contamination.
- Reduces confusion on the battlefield.
- Reduces demand on logistics support elements.
- Improves contamination control and reporting: One location and one person in charge.
- Reduces overall security requirements.
- Speeds PDS closure by using the thorough decontamination site.

b. An identified disadvantage is the increased size of the site and the requirement for medical support augmentation (a treatment squad from another organization with required patient decontamination and treatment MESs) to operate the PDS.

NOTE

Organic medical personnel must not be used to perform the HSS mission at the collocated site. They must go through the decontamination process with their unit.

c. These operations do not require that both patient decontamination and unit thorough decontamination be executed simultaneously. The PDS can be running while the thorough decontamination site is being prepared. Patient decontamination cannot be delayed since patients may be suffering life-threatening injuries as well as exposure to NBC agents. Therefore, the PDS must be established and operational before the first patients arrive. The wind direction must be common to both sites.

d. The decontamination platoon leader is responsible for establishing the combined decontamination site. The medical unit commander/surgeon coordinates with the decontamination platoon leader for the location of the patient receiving, PDS, and MTF. The lowest level at which this operation will usually be planned is brigade. This operation requires extensive planning and must involve the brigade chemical officer, brigade S4, and the medical company commander/brigade surgeon. Decontamination support for special operation forces, other unique operational organizations, or for nonlinear operations may require execution at a lower level. The supporting medical personnel operate the PDS. Nonmedical personnel perform patient decontamination procedures under medical supervision. Patient decontamination procedures are described below.

NOTE

Patient decontamination differs from thorough decontamination in that the patients' medical status must be monitored and medical treatment must be provided during the decontamination process.

[G-4]

e. Although a PDS may be collocated with thorough decontamination, a PDS must be operational at Levels I, II, III, and IV MTFs. Contaminated patients may present directly to the MTF for care, or patients previously decontaminated may become contaminated en route. Therefore, all patients arriving at an MTF must be checked for contamination. If contaminated, they must be decontaminated before they are admitted to the MTF.

Figure G-2. Thorough decontamination site collocated with patient decontamination station, without collective protection shelter.

[G-5]

#### G-4. Patient Decontamination at the Battalion Aid Station (Level I)

a. When battle conditions prevent patient decontamination procedures forward or the patient is contaminated en route, the patient may have to be decontaminated at the BAS. Contaminated patients arriving at the BAS must be decontaminated before admission into the clean treatment area.

b. Patient decontamination is performed by eight nonmedical personnel from the supported unit at the BAS. The patient decontamination personnel operate as two-man teams to perform the patient decontamination procedures. The patient decontamination teams operate under the supervision of medical personnel to ensure that no further injury is caused to the patient by the decontamination process. Each team receives a patient from the triage point and performs both clothing removal and skin decontamination procedures. The team requires assistance from another team to perform litter changes; see details below.

#### G-5. Patient Decontamination at the Medical Company Clearing Station (Level II)

The medical company clearing station may receive patients from the BAS or directly from other areas who have not been decontaminated. The clearing station must also have a patient decontamination area. As with the BAS, the clearing station must have a minimum of eight nonmedical personnel from the supported units to perform patient decontamination. Procedures for patient decontamination at the clearing station are the same as for the BAS.

#### G-6. Patient Decontamination at a Hospital (Level III or IV)

To the maximum extent possible, hospitals are located away from tactical or logistical targets. Contaminated patients will arrive from forward MTFs and units located within the geographical area of the hospital. Patient decontamination is done by at least 20 nonmedical personnel from units located in the geographical area/base cluster of the hospital. Procedures for patient decontamination at the hospital are the same as for the BAS. However, several patient decontamination stations can be operated simultaneously at the hospital patient decontamination site. Further, all patients arriving at the hospital will be decontaminated and receive full treatment within the capabilities of the hospital.

#### G-7. Prepare Hypochlorite Solutions for Patient Decontamination

An alternative patient decontamination agent is a hypochlorite solution; however, the hypochlorite solution must be prepared. Two concentrations of the hypochlorite solution are required. A 5 percent hypochlorite solution to decontaminate gloves, aprons, litters, cutting devices, the patient's mask hood, and other nonskin contact areas. The patient's mask, skin, splints, and tourniquets and their wounds are irrigated using a 0.5 (½) percent hypochlorite solution. To prepare the solutions, use calcium hypochlorite (HTH) granules (supplied in 6-ounce jars in the chemical agent patient treatment and chemical agent patient decontamination MES), bulk HTH, or sodium hypochlorite (household bleach). Prepare the required solutions as shown in Table G-1 below.

[G-6]

Table G-1. Preparation of Hypochlorite Solutions for Patient Decontamination

HTH OUNCES | HTH MRE SPOONFULS | HOUSEHOLD BLEACH | PERCENT IN 5 GALLONS OF WATER
--- | --- | --- | ---
6 | [*]5 | 2 QUARTS | 0.5
48 | 40 | [**] | 5.0
[*] THESE MEASUREMENTS ARE USED WHEN BULK HTH IS USED. TO MEASURE THIS PREPARATION, USE THE PLASTIC SPOON SUPPLIED WITH YOUR MEAL, READY-TO-EAT (MRE). THE AMOUNT OF HYPOCHLORITE TO BE USED IS A HEAPING SPOONFUL (THAT IS, ALL THAT THE SPOON WILL HOLD). DO NOT SHAKE ANY GRANULES OFF OF THE SPOON BEFORE ADDING TO THE WATER.
[**] DO NOT DILUTE IN WATER; HOUSEHOLD BLEACH IS 5 TO 6.25 PERCENT SOLUTION; IT IS USED FULL STRENGTH FOR 5 PERCENT APPLICATIONS.

CAUTIONS

1. Do not use the 5 percent hypochlorite solution on the patient's skin. The 5 percent solution can burn the skin.

2. Only wipe the skin when applying the 0.5 percent hypochlorite solution. Vigorous scrubbing may force the agent into the skin.

#### G-8. Classification of Patients

On the NBC battlefield, two classifications of patients will be encountered—contaminated and uncontaminated. Those contaminated may suffer from the effects of an NBC agent, of a conventional wound, or both. Some may suffer combat stress or heat injuries induced by the stress of NBC conditions and extended time spent in MOPP Level 4. It is important to follow proper decontamination procedures to limit the spread of contamination to others and equipment. The most important decontamination is performed at the site of contamination. Decontamination at a later time may be too late to prevent injury to the individual, especially when exposed to vesicants. All agents should be promptly removed from the skin.

#### G-9. Patient Treatment

This appendix only describes patient decontamination procedures. For NBC treatment procedures, refer to FM 4-02.283, FM 8-284, and FM 8-285.

[G-7]

### Section II. PATIENT DECONTAMINATION PROCEDURES

#### G-10. Decontaminate a Litter Chemical Agent Patient

Before contaminated patients receive medical treatment in the clean treatment area, they must be decontaminated. Place the cutting device in a container of 5 percent hypochlorite solution between each use. Each decontamination team member decontaminates his gloves and apron with the 5 percent hypochlorite solution frequently to prevent spreading any contamination to patient's skin. Decontaminate the patient's skin, bandages, wounds, mask, identification tags with chain, and splints with a 0.5 percent hypochlorite solution. The litter patient is decontaminated and undressed as follows:

NOTE

Litter patients requiring EMT or ATM in the clean area of the MTF will be completely decontaminated. A patient not requiring clean EMT or ATM at the MTF, but requiring further evacuation (for example: a stable patient with a partial amputation of a lower extremity) should only have his wound area and MOPP spot decontaminated to remove any gross contamination. The patient should be evacuated in his MOPP.

a. Step 1. Physically remove gross contamination. Use any stiff material (stick, cardboard, plastic strip, metal banding strap) to physically remove gross contamination from the patient's MOPP ensemble. Much of the CW agent contamination can be removed through physical means.

b. Step 2. Decontaminate the patient's mask and hood. The patient has been triaged and stabilized (if necessary) by the senior trauma specialist in the patient decontamination area. A two-man decontamination team moves him to the litter stands at the clothing removal station.

(1) Decontaminate the mask and hood. Use the SDK, or use a 5 percent hypochlorite solution or household bleach to sponge down the front, sides, and top of the mask hood. Decontaminate spots with the SDK or the 5 percent hypochlorite solution.

(2) Remove hood. Remove the hood by cutting the hood. Before cutting the hood, dip the cutting device in a 5 percent hypochlorite solution. For the M17-series mask, cut the neck cord and the small string under the voicemitter. Release or cut the hood shoulder straps and unzip the hood zipper. Cut the hood, close to the filter inlet cover and eye-lens outsert, upward to the top of the eye-lens outsert, and across the forehead to the outer edge of the other eye-lens outsert. Proceed downward toward the patient's shoulder, staying close to the eye-lens, then across the lower part of the voicemitter to the zipper. After dipping the cutting device in the 5 percent hypochlorite solution, cut the hood from the center of the forehead over the top of the head (see Figure G-3). Fold the left and right sides of the hood to the side of the patient's head, laying the sides of the hood on the litter. For the M40-series protective mask cut the [G-8] hood shoulder straps, then cut the quick-doff hood from the front bottom center to the chin through the elastic band under the chin. Fold the left and right sides of the hood over the shoulders away from the head.

Figure G-3. Cutting the M17 protective mask hood.

(3) Decontaminate the protective mask and exposed skin. Using the SDK, soap and water, or a 0.5 percent hypochlorite solution, wipe the external parts of the mask. Cover the mask air inlet(s) with gauze or your hand to keep the mask filter dry. Continue by wiping the exposed areas of the patient's face, including the neck and behind the ears.

(4) Remove the Field Medical Card. Cut the patient's FMC tie wire, allowing the FMC to fall into a plastic bag. Seal the plastic bag and rinse the outside of the bag with a 5 percent hypochlorite solution. Place the plastic bag with the FMC under the back of the protective mask head straps. The FMC will remain with the patient.

c. Step 3. Remove gross contamination from the patient's overgarment. Remove all visible gross contamination by scraping with a stick or other device.

d. Step 4. Remove the patient's personal effects and protective overgarment.

(1) Remove patient's personal effects. Remove the patient's personal effects from his protective overgarment and BDU pockets. Place the articles in a plastic bag, label with the patient's identification, and seal the bag. If the articles are not contaminated, return them to the patient. If the articles are contaminated, place them in the contaminated holding area until they can be decontaminated, and then return them to the patient.

(2) Cut the patient's overgarment. The overgarment jacket and trousers may be cut simultaneously. Two persons may be cutting clothing at the same time. Cut around bandages, tourniquets, and splints, leaving them in place.

NOTE

A cut is a separation of material by use of a cutting device that cuts material into two pieces. EXAMPLE: Cutting the sleeve from the cuff to the jacket collar is one cut.

[G-9]

CAUTION

Bandages may have been applied to control severe bleeding and are treated like tourniquets. Only medical personnel remove bandages, tourniquets, and splints.

(3) Remove overgarment jacket. Make two cuts, one up each sleeve from the wrist up to the shoulder, and then through the collar (Figure G-4). Do not allow the gloves to touch the patient along the cut line. Dip the cutting device in the 5 percent hypochlorite solution before making each cut to prevent contamination of the patient's uniform or underclothing. Keep the cuts close to the inside of the arms so that most of the sleeve material can be folded outward. Unzip the jacket; roll the chest sections to the respective sides, with the inner surface outward. Continue by tucking the clothing between the arm and chest. Roll the cut sleeves away from the arms, exposing the black liner.

Figure G-4. Cutting the overgarment jacket.

(4) Remove overgarment trousers. Cut both trouser legs starting at the ankle as shown in Figure G-5. Keep the cuts near the inseams to the crotch. With the left leg, continue cutting to the waist, avoiding the pockets. With the right leg, cut across at the crotch to the left leg cut. Place the cutting device in the 5 percent hypochlorite solution. Fold the cut trouser halves away from the patient and allow the halves to drop to the litter with contaminated (green) side down. Roll the inner leg portion under and between the legs.

Figure G-5. Cutting the overgarment trousers.

[G-10]

(5) Remove outer gloves. This procedure can be done with one person on each side of the patient working simultaneously. The decontamination team will decontaminate their gloves in 5 percent hypochlorite solution. Next, lift the patient's arms up and out of the cutaway sleeves unless detrimental to the patient's condition. Grasp the fingers of the glove, roll the cuff over the fingers, turning the glove inside out. Do not remove the inner cotton glove liners at this time. Carefully lower the arms across the chest after the outer gloves have been removed (Figure G-6). Do not allow the patient's arms to come into contact with the exterior of his overgarment. Drop his gloves into the contaminated waste bag. Dip your gloves in the 5 percent hypochlorite solution.

Figure G-6. Remove outer gloves and position arms after glove removal.

(6) Remove overboots. Cut the overboot laces and fold the lacing eyelets flat outwards. If the green vinyl overboot (GVO) is worn, first try to remove the overboot without cutting; if necessary, cut the boot along the front. While standing at the foot of the litter, hold the heel with one hand, pull overboot downwards, and then pull towards you to remove the overboot over the combat boot heel. Remove the two overboots simultaneously. This reduces the likelihood of contaminating one of the combat boots. While holding the heels off the litter, have a decontamination team member wipe the end of the litter with the 5 percent hypochlorite solution to neutralize any liquid contamination that was transferred to the litter from the overboots. Lower the patient's heels onto the decontaminated litter. Place the overboots in the contaminated waste bag. Decontamination personnel dip their gloves in the 5 percent hypochlorite solution.

e. Step 5. Remove patient's battle dress uniform.

(1) Remove battle dress uniform. Cut the BDU jacket and trousers as described above for the protective overgarment. Roll the jacket and trousers as described for the protective overgarment.

(2) Remove combat boots. Cut the bootlaces along the tongue. Remove the boots by pulling them towards you. Place the boots in the contaminated waste bag. Do not touch the patient's skin with contaminated gloves when removing his boots.

[G-11]

(3) Remove undergarments. Remove the patient's tee shirt. Dip the cutting device in the 5 percent hypochlorite solution between each cut. Cut both sleeves from the inside, starting at the elbow, up to the armpit. Continue cutting across the shoulder to the collar. Cut around bandages or splints, leaving them in place. Next, peel the tee shirt away from the body to avoid spreading contamination. If the patient is wearing a brassiere, cut it between the cups. Cut both shoulder straps where they attach to the cups and lay them back off of the shoulders. Remove the patient's under shorts/panties by cutting from the lower side of the hip to the waist on both sides. Fold the front flap of the shorts/panties down between the patient's legs onto the litter. Do not allow the outside of the garment to touch the patient's skin. Remove the socks and cotton glove liners. Do not remove the patient's identification tags.

f. Step 6. Transfer the patient to a decontamination litter. After the patient's clothing has been cut away, he is transferred to a decontamination litter or a canvas litter with a plastic sheeting cover. Three decontamination team members decontaminate their gloves and aprons with the 5 percent hypochlorite solution. One member places his hands under the patient's legs at the thighs and Achilles tendons, a second member places his arms under the patient's back and buttocks, and a third member places his arms under the patient's shoulders and supports the head and neck. They carefully lift the patient using their knees (not their backs) to minimize back strain. While the patient is elevated, another decontamination team member removes the litter from the litter stands and replaces it with a decontaminated (clean) litter. The patient is carefully lowered onto the clean litter. The contaminated clothing and overgarments are placed in bags and moved to the contaminated waste dump. The dirty litter is rinsed with the 5 percent hypochlorite solution and placed in the litter storage area.

g. Step 7. Decontaminate skin.

(1) Spot decontamination. With the patient in a supine position, spot decontaminate the skin using the SDK or a 0.5 percent hypochlorite solution. Decontaminate areas of potential contamination. Include areas around the neck, wrists, and lower parts of the face. Decontaminate the patient's identification tags and chain, if necessary.

NOTE

Complete body wash is not appropriate and may be injurious to the patient. During complete body wash, the patient would have to be rolled over to reach all areas of the skin. This is not necessary for adequate decontamination.

(2) Trauma specialist care. During decontamination, the clothing around bandages, tourniquets, and splints was cut and left in place.

- The trauma specialist replaces the old tourniquet by placing a new tourniquet ½ to 1 inch above the old one. He then removes the old tourniquet and decontaminates the patient's skin using the M291 pads or a 0.5 percent hypochlorite solution.
- [G-12] The trauma specialist gently cuts away bandages and decontaminates the area around the wound; dusts the wound with the SDK, or irrigates soft tissue wounds with the 0.5 percent hypochlorite solution. If bleeding begins, the trauma specialist replaces the bandage with a clean one. The trauma specialist ensures splints are not removed, but are decontaminated in place by applying the 0.5 percent hypochlorite solution to them, to include the padding and cravats. Splints will only be removed by a physician or under the supervision of a physician.

WARNINGS

1. DO NOT apply the SDK or irrigate wounds in the abdominal and thoracic cavities or intracranial head injuries.

2. DO NOT remove splints.

(3) Check patient for completeness of decontamination. The patient is checked with the CAM or with M8 detector paper for completeness of decontamination.

NOTE

Other monitoring devices may be used when available.

(4) Dispose of contaminated waste. Dispose of contaminated bandages and coverings by placing them in a contaminated waste bag. Seal the bag and place it in the contaminated waste dump.

h. Step 8. Transfer the patient across the shuffle pit.

(1) The patient's clothing has been cut away; his skin, bandages, and splints have been decontaminated. Now the litter is transferred to the shuffle pit and placed upon the litter stands. The shuffle pit is wide enough to prevent the patient decontamination team members from straddling it while carrying the litter. Four decontamination team members transfer the patient to a clean treatment litter in the shuffle pit. A member of the patient decontamination team removes the bagged FMC and holds it so that a trauma specialist on the clean side of the hot line can read it. A trauma specialist on the clean side of the hot line prepares a new FMC before the patient is moved to the clean area. The old FMC is disposed of with other contaminated waste.

(2) Decontamination team members rinse or wipe down their aprons and gloves with the 5 percent hypochlorite solution.

(3) Three decontamination team members lift the patient off the decontamination litter (see Step 6 for lifting procedures).

[G-13]

(4) While the patient is elevated, another decontamination team member removes the litter from the stands and returns it to the decontamination area. A trauma specialist from the clean side of the shuffle pit replaces the litter with a clean one. The patient is lowered onto the clean litter. Two trauma specialists from the clean side of the shuffle pit move the patient to the clean treatment area. The patient is treated in this area or waits for processing into the CPS. The litter removed by the decontamination team member is wiped down with the 5 percent hypochlorite solution in preparation for reuse.

NOTE

Before decontaminating another patient, each decontamination team member drinks approximately one-half quart of water. The exact amount of water consumed is increased or decreased according to the temperature (see Table G-2 below).

#### G-11. Decontaminate an Ambulatory Chemical Agent Patient

a. All ambulatory patients requiring EMT or ATM in the clean area of the BAS will be decontaminated. A member of the decontamination team or other ambulatory patients will assist the patient in removing his clothing and decontaminating his skin.

b. Patients requiring only minimal care will undergo spot decontamination of their MOPP gear as required for their medical treatment. They will be treated in the contaminated EMT area and returned to duty. They will undergo decontamination and a MOPP gear exchange with their unit.

c. Stable patients not requiring treatment at the BAS, but requiring evacuation to a higher level of care for treatment (example: A patient with a broken arm) should be evacuated in MOPP Level 4 by any available transportation. However, before evacuation, spot remove all thickened/persistent agents from protective clothing.

NOTES

1. Remember, do not remove clothing from an ambulatory patient unless he requires treatment in the clean treatment area of the BAS or clearing station. Only spot decontaminate the patient's clothing and evacuate him to the next level of care.

2. Place cutting device used in this procedure in a container of 5 percent hypochlorite solution when not in use. Most ambulatory patients will be treated in the contaminated treatment area and returned to duty. Upon removal of an ambulatory patient's clothing, he becomes a litter patient. The BAS and clearing station do not have clothing to replace those cut off during the decontamination process. The patient must be placed in a PPW for protection during evacuation. A battery operated blower unit with a CB filter may be attached to the PPW to provide fresh air to the patient; thus reducing the carbon dioxide buildup inside the PPW (Figure G-7).

Figure G-7. Chemical warfare agent protective patient wrap.

[G-15]

d. Step 1. Remove load-carrying equipment. Remove load-carrying equipment (LCE) by unfastening/unbuttoning all connectors or tie straps; then place the equipment in a plastic bag. Place the plastic bag in the designated storage area for later decontamination.

e. Step 2. Decontaminate the patient's mask and hood. After the patient has been triaged and treated (if necessary) by the senior trauma specialist in the PDS, the patient (assisted by another ambulatory patient or a member of the patient decontamination team, if necessary) begins the clothing removal process.

(1) Decontaminate and remove mask hood. Sponge down the front, sides, and top of the hood with a 5 percent hypochlorite solution. Remove the hood by cutting (Figure G-3) or, with the quick-doff hood or other hoods, by loosening the hood from the mask attachment points. Before cutting the hood, dip the cutting device in the 5 percent hypochlorite solution. Begin by cutting the neck cord and the small string under the voicemitter. Next, release or cut the hood shoulder straps and unzip the hood zipper. Proceed by cutting the hood upward, close to the filter inlet cover and eye-lens outserts, to the top of the eye-lens outsert, across the forehead to the outer edge of the other eye-lens outsert. Proceed downward toward the patient's shoulder, staying close to the eye-lens and filter inlet. Cut across the lower part of the voicemitter to the zipper. After dipping the cutting device in the 5 percent hypochlorite solution again, cut the hood from the center of the forehead over the top of the head and fold the right and left sides of the hood away from the patient's head, removing the hood.

(2) Decontaminate the mask and patient's face. Decontaminate the mask and the patient's face by using the SDK or a 0.5 percent hypochlorite solution. Wipe the external parts of the mask; cover both mask air inlets with gauze or your hands to keep the mask filters dry. Continue by wiping the exposed areas of the patient's face, to include the neck and behind the ears.

f. Step 3. Remove Field Medical Card. Cut the FMC tie wire, allowing the card to fall into a plastic bag. Seal the plastic bag and rinse it with the 5 percent hypochlorite solution. Place the plastic bag under the back of the protective mask head straps.

g. Step 4. Remove all gross contamination from the patient's overgarment. Remove all visible contamination spots by using the SDK (preferred method) or a sponge dipped in a 5 percent hypochlorite solution.

h. Step 5. Remove overgarments.

(1) Remove the patient's personal effects. Place the patient's personal effects in a clean bag and label with the patient's identification. If they are not contaminated, give them to him. If his personal effects are contaminated, place the bagged items in the contaminated storage area until they can be decontaminated, then return them to the patient.

(2) Remove overgarment jacket. Have the patient stand with his feet spread apart at shoulder width. Unsnap the jacket front flap and unzip the jacket. If the patient can extend his arms, have him clinch his fists and extend his arms backward at about a 30° angle. Move behind the patient, grasping his jacket collar at the sides of the neck, peel the jacket off the shoulders at a 30° angle down and away from the patient. Avoid any rapid or sharp jerks that can spread contamination. Gently pull the inside sleeves [G-16] over the patient's wrists and hands. If the patient cannot extend his arms, you must cut the jacket to aid in its removal. Dip the cutting device in the 5 percent hypochlorite solution between each cut. As with the litter patient, cut both sleeves from the inside, starting at the wrist, up to the armpit. Continue cutting across the shoulder to the collar. Cut around bandages or splints, leaving them in place. Next, peel the jacket back and downward to avoid spreading contamination. Ensure that the outside of the jacket does not touch the patient or his inner clothing.

(3) Remove overgarment trousers. Unfasten or cut all ties, buttons, or zippers before grasping the trousers at the waist and peeling them down over the patient's combat boots. Again, the trousers are cut to aid in removal. If necessary, cut both trouser legs starting at the ankle, keeping the cuts near the inside of the legs, along the inseam, to the crotch. Cut around all bandages, tourniquets, or splints. Continue to cut up both sides of the zipper to the waist and allow the narrow strip with the zipper to drop between the legs. Place the cutting device in the 5 percent hypochlorite solution. Peel or allow the trouser halves to drop to the ground. Have the patient step out of the trouser legs, one at a time. Place the trousers in the contaminated disposal bag.

(4) Remove overboots. Remove the patient's overboots by cutting the laces with cutting device dipped in the 5 percent hypochlorite solution. Fold the lacing eyelets flat on the ground. Step on the toe and heel eyelets to hold the overboot on the ground and have the patient step out of it. Repeat this procedure for the other overboot. If the GVO are worn, first try to remove the overboots without cutting; if necessary, cut the overboots along the front. If the overboots are in good condition, they can be decontaminated and reissued.

(5) Remove the patient's outer gloves. Grasp the heel of the glove, peel the glove off with a smooth downward motion. Place the contaminated gloves in a plastic bag with the overgarment jacket. Do not allow the patient to touch his clothing or other contaminated objects with his exposed hands.

(6) Remove the patient's cotton glove liners. Have the patient remove his cotton glove liners to reduce the possibility of spreading contamination. Have the patient grasp the heel of one glove liner with the other gloved hand, peeling it off of his hand. Hold the removed glove by the inside and grasp the heel of the other glove, peeling it off of his hand. Place both glove inserts in the contaminated waste bag.

i. Step 6. Remove patients BDU.

(1) Remove the patient's personal effects. Place the patient's personal effects in a clean bag and label with the patient's identification. If they are not contaminated, give them to him. If his personal effects are contaminated, place the bagged items in the contaminated storage area until they can be decontaminated, then return them to the patient.

(2) Remove BDU jacket. Have the patient stand with his feet spread apart at shoulder width. Unbutton the front flap of the jacket. If the patient can extend his arms, have him clinch his fists and extend his arms backward at about a 30° angle. Move behind the patient, grasping his jacket collar at the sides of the neck, peel the jacket off the shoulders at a 30° angle down and away from the patient. Avoid any rapid or sharp jerks that can spread contamination. Gently pull the inside sleeves over the patient's wrists and hands. If the patient cannot extend his arms, you must cut the jacket to aid in its removal. Dip [G-17] the cutting device in the 5 percent hypochlorite solution between each cut. As with the litter patient, cut both sleeves from the inside, starting at the wrist, up to the armpit. Continue cutting across the shoulder to the collar. Cut around bandages or splints, leaving them in place. Next, peel the jacket back and downward to avoid spreading contamination. Ensure that the outside of the jacket does not touch the patient or his inner clothing.

(3) Remove BDU trousers. Unfasten or cut all ties, buttons, or zippers before grasping the trousers at the waist and peeling them down over the patient's combat boots. Again, the trousers are cut to aid in removal. If necessary, cut both trouser legs starting at the ankle, keeping the cuts near the inside of the legs, along the inseam, to the crotch. Cut around all bandages, tourniquets, or splints. Continue to cut up both sides of the zipper to the waist and allow the narrow strip with the zipper to drop between the legs. Place the cutting device in the 5 percent hypochlorite solution. Peel or allow the trouser halves to drop to the ground. Have the patient step out of the trouser legs, one at a time. Place the trousers in the contaminated disposal bag.

(4) Remove undergarments. Remove the patient's tee shirt. Dip the cutting device in the 5 percent hypochlorite solution between each cut. Cut both sleeves from the inside, starting at the elbow, up to the armpit. Continue cutting across the shoulder to the collar. Cut around bandages or splints, leaving them in place. Next, peel the tee shirt away from the body to avoid spreading contamination. If the patient is wearing a brassiere, cut it between the cups. Cut both shoulder straps where they attach to the cups and lay them back off of the shoulders. Remove the patient's under shorts/panties by cutting from the lower side of the hip to the waist on both sides. Allow the shorts/panties to fall to the ground. Do not remove the patient's identification tags.

j. Step 7. Check patient for contamination. After the patient's BDU and underwear has been removed check the skin for contamination by using M8 detector paper or the CAM. Carefully survey all areas of the patient's skin, paying particular attention to areas around the neck, wrist, ears, and dressings, splints, or tourniquets.

k. Step 8. Decontaminate skin.

(1) Spot decontamination. Use the SDK or the 0.5 percent hypochlorite solution to spot decontaminate exposed neck and wrist areas, splints, other areas where the protective overgarment was damaged, and where dressings or bandages were removed. Decontaminate the patient's identification tags, if necessary. Have the patient hold his breath and close his eyes. Have him, or assist him, lift his mask at the chin. Wipe his face with the M291 pad or the 0.5 percent hypochlorite solution. Wipe quickly from below the top of one ear, being careful to wipe all folds of the skin, top of the upper lip, chin, dimples, earlobes, and nose. Continue up the other side of the face to the top of the other ear. Wipe the inside of the mask where it touches the face. Have the patient reseal and check his mask.

CAUTION

Keep the decontamination solution out of the patient's eyes.

[G-18]

(2) Trauma specialist care. During clothing removal, the clothing around bandages, tourniquets, and splints was cut and left in place.

- The trauma specialist replaces the old tourniquet by placing a new one ½ to 1 inch above the old tourniquet. When the old tourniquet is removed, the skin is decontaminated with the SDK or the 0.5 percent hypochlorite solution.
- Do not remove splints. Decontaminate them by thoroughly rinsing the splint, padding, and cravats with the 0.5 percent hypochlorite solution.
- Usually, the trauma specialist will gently cut away bandages. The area around the wound is dusted with the M291 pad or rinsed with the 0.5 percent hypochlorite solution, and the trauma specialist applies the M291 pad or irrigates the soft tissue wound with the 0.5 percent hypochlorite solution. If bleeding begins, the trauma specialist replaces the bandage with a clean one.

l. Step 9. Dispose of contaminated waste. Dispose of contaminated bandages and coverings by placing them in a plastic bag and sealing the bag with tape. Place the plastic bags in the contaminated waste dump.

m. Step 10. Proceed through the shuffle pit to the clean treatment area. Have the decontaminated patient proceed through the shuffle pit to the clean treatment area. Make sure that the patient's boots are thoroughly decontaminated by stirring the contents of the shuffle pit with his boots as he crosses it. The patient will remove his combat boots and socks at the entrance of the clean treatment area or CPS; remove the protective mask at the entrance to the clean treatment area or inside the ambulatory air lock of the CPS.

#### G-12. Biological Patient Decontamination Procedures

The decontamination station as established for chemical agent patients is also used for biologically contaminated patients. The eight-man patient decontamination team is required for biologically contaminated patient decontamination procedures.

#### G-13. Decontaminate a Litter Biological Agent Patient

a. Remove the patient's personal effects. Place the patient's personal effects in a clean bag and label with the patient's identification. If they are not contaminated, give them to him. If his personal effects are contaminated, place the bagged items in the contaminated storage area until they can be decontaminated, and then return them to the patient.

b. Remove the Field Medical Card. Remove the FMC by cutting the tie wire and allowing the FMC to drop into a plastic bag. Keep the FMC with the patient.

[G-19]

c. Remove the patient's clothing. Patient decontamination team members first apply the 5 percent hypochlorite solution to the patient's clothing and the litter. Then, remove the patient's clothing as in decontamination of chemical agent patients. Bandages, tourniquets, and splints are not removed. Move patient to a clean litter as described for a chemical agent patient. Place patient's clothing in a plastic bag and dispose in the contaminated waste dump.

d. Decontaminate the patient's skin. Bathe the patient with soap and warm water or apply the 0.5 percent hypochlorite solution. The trauma specialist places a new tourniquet ½ to 1 inch above the old tourniquet, and then he removes the old one. The trauma specialist removes bandages and decontaminates the skin and wound with the 0.5 percent hypochlorite solution; he replaces the bandage, if needed, to control hemorrhage. Splints are disinfected by soaking the splint, cravats, and straps with the 0.5 percent hypochlorite solution.

NOTE

Use a 0.5 percent hypochlorite solution to decontaminate patients suspected of being contaminated with mycotoxins.

e. Transfer patient to hot line. Two decontamination team members move patient to the hot line. Request assistance from two other decontamination team members to transfer him to a clean litter as described for chemical agent patients. Place the patient's FMC in the plastic bag on the clean litter with him. Two trauma specialists from the clean side of the hot line move the patient from the hot line to the clean treatment/holding area.

#### G-14. Decontaminate an Ambulatory Biological Agent Patient

a. Remove the patient's personal effects. Place the patient's personal effects in a clean bag and label with the patient's identification. If they are not contaminated, give them to him. If his personal effects are contaminated, place the bagged items in the contaminated storage area until they can be decontaminated, then return them to the patient.

b. Remove the Field Medical Card. Remove the FMC by cutting the tie wire and allowing the FMC to drop into a plastic bag. Keep the FMC with the patient.

c. Remove the patient's clothing. Patient decontamination team members first apply the 5 percent hypochlorite solution to the patient's clothing. Then remove the patient's clothing as in decontamination of chemical agent patients. Bandages, tourniquets, and splints are not removed. Place patient's clothing in a plastic bag and dispose in the contaminated waste dump.

d. Decontaminate the patient's skin. Have the patient bathe with soap and warm water or apply the 0.5 percent hypochlorite solution. If the patient is unable to bathe himself, a member of the [G-20] decontamination team must bathe him. The trauma specialist places a new tourniquet ½ to 1 inch above the old tourniquet, and then he removes the old one. The trauma specialist removes bandages and decontaminates the skin and wound with the 0.5 percent hypochlorite solution; he replaces the bandage, if needed, to control hemorrhage. Splints are disinfected by soaking the splint, cravats, and straps with the 0.5 percent hypochlorite solution.

NOTE

Use a 0.5 percent hypochlorite solution to decontaminate ambulatory patients suspected of being contaminated with mycotoxins.

e. Direct patient across hot line. Direct the patient to cross the hot line to the clean treatment area. His boots must be decontaminated at the hot line before he enters the clean treatment area.

NOTES

1. Remember, do not remove clothing from an ambulatory patient unless he requires treatment in the clean treatment area of the BAS or clearing station. Only spot decontaminate the patient's clothing and evacuate him to the next level of care.

2. Place cutting device used in this procedure in a container of 5 percent hypochlorite solution when not in use. Most ambulatory patients will be treated in the contaminated treatment area and returned to duty. Upon removal of an ambulatory patient's clothing, he becomes a litter patient. The BAS and clearing station do not have clothing to replace those cut off during the decontamination process. The patient must be placed in a PPW for protection during evacuation (Figure G-7).

#### G-15. Decontaminate Nuclear-Contaminated Patients

The practical decontamination of nuclear-contaminated patients is easily accomplished without interfering with the required medical care.

NOTE

Patients must be monitored by using a radiac meter (AN/VDR2, AN/PDR27, or AN/PDR77) before, during, and after each step of the decontamination procedure.

[G-21]

#### G-16. Decontaminate a Litter Nuclear-Contaminated Patient

a. Remove patient's personal effects. Patient decontamination team members remove the patient's personal effects and place them in a plastic bag. Place plastic bag in a clean holding area.

b. Remove patient's clothing. Patient decontamination team members remove the patient's outer clothing as described for chemical agent patients. Do not remove bandages, tourniquets, or splints. Move the patient to a clean litter. Place the patient's contaminated clothing in a plastic bag and move the bagged clothing to the contaminated waste dump.

NOTE

Patients arriving at the MTF in MOPP will only have their MOPP removed. They can remain in their BDU unless contamination is found on it.

c. Spot decontaminate patient's skin. Wash exposed skin surfaces with soap and warm water. Wash the hair with soap and warm water, or clip the hair and wash the scalp with soap and warm water.

d. Transfer patient to hot line. Move the patient to the hot line. Two trauma specialists from the clean side of the hot line move the patient into the clean treatment area.

#### G-17. Decontaminate an Ambulatory Nuclear-Contaminated Patient

a. Remove patient's personal effects. Have the patient remove his personal effects and place them in a plastic bag.

b. Remove patient's outer clothing. Have the patient remove his outer clothing (or have a decontamination team member assist him). Place his contaminated clothing in a plastic bag and move the bagged clothing to the contaminated waste dump.

NOTE

Patients arriving at the MTF in MOPP will only have their MOPP removed. They can remain ambulatory in their BDU unless contamination is found on it.

c. Spot decontaminate patient's skin. Have the patient wash his exposed skin surfaces with soap and warm water. Wash his hair with soap and water, or clip the hair and wash the scalp with soap and water.

[G-22]

d. Transfer patient to hot line. Direct the patient to move to the hot line. Decontaminate his boots by stirring the shuffle pit contents with his feet before he crosses into the clean treatment area.

NOTE

If a new protective overgarment is not available, after treatment, the ambulatory patient must be placed in a PPW for protection during MEDEVAC to the next level of care MTF. Thus, he becomes a litter patient for evacuation.

[H-1]

## APPENDIX H
FIELD EXPEDIENT PROTECTIVE SYSTEMS AGAINST NUCLEAR, BIOLOGICAL, AND CHEMICAL ATTACK

#### H-1. General

Medical units must have protection from NBC attack and contamination to survive and function effectively. The extent of protection provided is only limited by the resources available and efforts of unit personnel. Protection as simple as an individually dug foxhole or as elaborate as the subbasement of a concrete building may be used. Expedient protection from the effects of biological and chemical agents are usually much less labor intensive.

#### H-2. Protection Against Radiation

The level of protection from radiation is expressed in terms of shielding. Material is available on the battlefield to construct/prepare expedient fallout shelters that offer substantial shielding against gamma radiation (see Table H-1). Generally, the denser or heavier the material, the better shielding it offers. The degree of protection afforded by a fallout shelter is expressed as a "protection factor," or a "transmission factor." The protection factor is simply the fraction of the available radiation dose that penetrates the shelter and reaches those inside compared to the radiation received by an unprotected person. Thus, a protection factor of 2 indicates that an individual in the shelter receives one-half of the radiation dose he would receive if unprotected. A protection factor of 100 (associated with about six half-value thicknesses) indicates that only 1/100 or 1 percent of the radiation dose reaches the inside. Transmission factors are expressed in percentages, or in decimals. Either refers to that fraction of the ambient unshielded dose that is received by personnel within the shelter. Fallout gamma transmission factors for some common shelters are shown in Table H-2.

Table H-1. Shielding Potential of Common Materials—Fallout Gamma Protection

| MATERIAL | 1/2 VALUE LAYER THICKNESS[*]
--- | --- | ---
| STEEL | 1.8 CM | (.7") |
| CONCRETE | 5.6 CM | (2.2")
| EARTH | 8.4 CM | (3.3")
| WATER | 12.2 CM | (4.8")
| WOOD | 22.4 CM | (8.8")

#### H-3. Expedient Shelters for Protection Against Radiation

a. In many cases it will be unnecessary to construct field expedient or other types of fallout shelters. There are many structures and terrain features available that afford a degree of fallout protection. Existing fallout shelters are tunnels, caves, culverts, overpasses, ditches, ravines, and man-made structures. The best existing shelters are basements. Figure H-1 shows typical protection provided in buildings. Windows can be sandbagged or covered with dirt from the outside to provide additional protection.

Figure H-1. Typical shelter protection provided in buildings.

[H-3]

b. Planners should attempt to locate HSS units near existing shelters, whenever possible. However, if an HSS unit is already established, or must be established where fallout shelters are not available, then a shelter must be constructed. Elaborate shelters are not required, since they usually only need to be occupied for a few days. There are a number of field expedients that will serve to save personnel and patients even though they may not be comfortable for those few days.

c. When engineer support is available, a bulldozer trench about 2.7 meters (9 feet) wide and 1.2 meters (4 feet) deep can be dug (Figure H-2). The length of the trench will be determined by the number of patients/personnel to be sheltered. About 0.6 meter (2 feet) length of trench is required for each person to be sheltered. These trenches reduce exposure of personnel lying on the floor to about 20 to 30 percent of the radiation that they would receive in the open. Protection and comfort can be improved, as time permits, by digging the trenches deeper; undercutting the walls (care must be taken in this option; the earth may cave in); erecting tents over the trenches; and providing improved flooring. When used with other individual and collective protection measures, bulldozer trenches provide adequate fallout shelters for most situations; they can be provided in a minimum of time and effort. Trenches should not be dug in areas subject to flooding during rainstorms; a berm should be formed on the uphill side of the trench to direct water around the trench in the event rainfall occurs in the area. Undercutting will not be possible in sandy soil; also some form of support to keep the walls from caving in is required.

Figure H-2. Dozer trench.

d. Dug-in tents (Figure H-3) for hospitals provide more comfort and require less movement than the bulldozer trench; however, they have two drawbacks. First, they offer far less radiation protection than the bulldozer trench, and second, they require considerably more engineer effort. This option should work well with GP tents, but will probably be hard to accomplish with the TEMPER.

[H-4]

Figure H-3. Dug-in tents.

e. Sandbagged walls around the hospital tents, as shown in Figure H-4, or lightly constructed buildings provide protection from fallout. Sandbagged walls 1.2 meters high give significant protection (20 to 40 percent transmission factor); however, the effort required to achieve the protection is such that it is marginally feasible. Sandbagging is an effective means for supplementing other shelters by—

- Bolstering the shielding at weak points.
- Forming baffles at entryways.
- Blocking open ends of trenches.
- Covering windows and gaps.

f. When other shelters are not available, HSS units must prepare foxholes and trenches for patients and unit personnel. As time permits, improve these shelters by deepening, covering, undercutting, and sandbagging.

[H-5]

Figure H-4. Sandbag walls around tents.

#### H-4. Expedient Shelters Against Biological and Chemical Agents

a. When CPS systems are not available, well-sealed shelters (TEMPER, ISO, and GP) can significantly minimize or prevent the entry of CB agents. The ventilation system must be turned off, and kept off, before, during, and after the attack. The shelter must be totally sealed during this time to maximize protection. Table H-3 provides examples of protection values for well-sealed shelters. For example, a well-sealed TEMPER will only permit 1/60 of the CB agent outside to enter the shelter. If a persistent agent is used, be aware of agent off-gassing hazards. Persistent agents can penetrate TEMPER fabric and create a vapor hazard inside. In a CB agent attack, ensure that all staff and patients are protected by wearing their MOPP or are in PPWs.

[H-6]

Table H-3. Ratio at Nonpersistent Agent Concentrations (Inside/Outside) for Different Shelters

SHELTER | RATIO INSIDE/ OUTSIDE
--- | ---
TEMPER TENT | 1:60[*]
GENERAL PURPOSE TENT, MEDIUM, WITH COTTON LINER | 1:50
GENERAL PURPOSE TENT, LARGE, WITH COTTON LINER | 1:30
ISO SHELTER | 1:60
[*] THE VENTILATION SYSTEM MUST BE TURNED OFF ON ALL SHELTERS TO PROVIDE THIS LEVEL OF PROTECTION.

b. Sealing shelters to prevent entry of CB agents does not require elaborate materials or procedures.

(1) Materials needed for sealing shelters include, but are not limited to the following:

- Duct tape (or similar tape) for sealing.
- Velcro kits for TEMPER.
- Sand/dirt to seal base of GP tents.
- Plastic sheeting and tape to seal large openings, such as doors and windows of GP tents.

(2) All vulnerable areas must be sealed. Seal—

- Joints in ISO shelters and GP tents with tape. Tape does not work very well on TEMPER fabrics; use Velcro kits.
- Base of GP tents with sand/dirt.
- Stove pipe openings with tape and plastic.
- Windows of GP tents with tape and plastic. Seal TEMPER tent windows by aligning and securing the Velcro border tightly; tape may be applied to the seams to provide some additional barrier.
- All ISO shelter doors that do not have CB protective seals, with tape. Seal GP tent doors with plastic sheeting and tape.
- All windows, doors, and other openings of fixed sites with plastic and tape.
- All air ventilation system vents.

[H-7]

NOTES

1. Do not allow any entries/exits to shelters during a CB attack.

2. In hot climates the heat load will rise in sealed shelters with the ventilation system turned off. Personnel must carefully monitor each other and the patients. All personnel must drink plenty of water to prevent heat injuries; see FM 21-10.

[I-1]

## APPENDIX I
DETECTION AND TREATMENT OF NUCLEAR, BIOLOGICAL, AND CHEMICAL CONTAMINATION IN WATER

#### I-1. General

Water supplies in areas with NBC contamination and in surface water supplied by runoff from such areas will most likely be contaminated. The contamination of water, whether intentional or inadvertent, may reach concentrations that will produce casualties. By special methods of analysis, the presence of contamination can be determined. Treatment of contaminated water requires chemicals and equipment that are only available to quartermaster water purification units; individuals or units should not attempt to treat their water. Decontamination of water is only undertaken when uncontaminated sources are not available; then ONLY with the approval of the medical authority (PVNTMED or surgeon).

#### I-2. Detection of Contamination in Water

a. Detection of nuclear contamination in water is accomplished by using the AN/PDR77, AN PDR/27 or AN VDR/2 radiac meters.

CAUTION

DO NOT allow the probe to come into contact with the water source; allow at least one inch of air space between the probe and water surface.

b. Detection of BW agents in water is accomplished by the use of field biological water test kits and specially designed collection and detection kits. The specialty kits will be provided as needed, and will be available to PVNTMED and supporting medical laboratory personnel. When required for the President and Secretary of Defense purpose, samples must be collected and prepared for shipment to the supporting medical laboratory. A chain of custody document must be prepared by the collector and maintained as the sample(s) is being transported to the supporting medical laboratory and throughout its transit to the CONUS laboratory. See Appendix F for details on suspect BW sample collection, packaging, chain of custody, and handling.

c. The Chemical Agent Water Testing Kit, M272, provides a rapid field test to detect chemical agent contamination in water. The test must be conducted before the water is treated with chlorine; the chlorine will affect the accuracy of the test for chemical agents.

#### I-3. Procedures on Discovery of Contamination in Water

When contamination is discovered the following actions are taken:

a. Mark the water source, using the standard NBC contamination markers, and ensure that personnel do not consume the water until approved.

[I-2]

b. Notify the commander that the water source is contaminated and unfit for drinking, food preparation, and personal hygiene.

c. Notify the supporting water production unit, such as the quartermaster water production and distribution unit of the contaminated water source.

d. The commander establishes safeguards to prevent personnel from using the contaminated water supply.

e. An alternative source of uncontaminated water is sought and used. The primary source for obtaining water is from quartermaster-operated water production and distribution points. Other sources are considered only when quartermaster-operated faculties are not available. Alternative sources that may be considered include—

- Ground water sources that are least likely to be contaminated.
- Local fixed facility water supplies. However, these supplies must be tested before use. If NBC contamination is found do not use.
- Using another location to obtain an uncontaminated water source, when the tactical situation permits.

f. Contaminated water must not be used until it has been treated by quartermaster water production and distribution units or other equally capable water purification units and approved for use by the medical authority.

#### I-4. Treatment of Contaminated Water

Contaminated water requires additional equipment and supplies to remove the contamination. Quartermaster water purification and distribution units are equipped to perform these duties. See FM 10-52 for details.

## APPENDIX J
FOOD CONTAMINATION AND DECONTAMINATION

#### J-1. General

a. Food Susceptibility. Stored, transported, and prepared food is susceptible to NBC contamination throughout the TO. Planning for any battle or operation must include food protection from contamination; food contamination detection; and contaminated food disposition (decontaminate or destroy).

b. Countermeasures. There are three primary countermeasures to overcome or reduce the NBC hazard to food:

(1) Contamination avoidance.

(2) Nuclear, biological, and chemical agent detection.

(3) Nuclear, biological, and chemical agent decontamination.

c. Priorities. The priorities for conducting NBC countermeasures are—

(1) Contamination avoidance. Contamination avoidance includes using natural and fabricated barriers to prevent, or significantly reduce the spread of contamination. Also, using specific procedures for entry and exit between contaminated and uncontaminated areas reduce the potential for spreading contamination. Use of these barriers and procedures may reduce the subsequent need for detection and decontamination.

(2) Detection, measurement, and identification. These activities are essential for determining the presence, extent, and nature of NBC contamination. This information is essential in identifying the existence of uncontaminated supplies, or decontamination requirements.

(3) Decontamination. Decontamination removes the contaminant and provides food that is safe for consumption.

d. Decontamination. Decontamination efforts require an extensive amount of labor, time, and supplies. The use of hasty decontamination is emphasized. That is, decontaminate just enough to sustain operations and keep fighting, rather than to make a contamination-free environment. Normally, decontamination efforts will be limited to the packaging and packing materials. Food decontamination will only occur in critical situations where other food supplies are not available. Most decontamination is performed in or very near the AO. Before beginning decontamination procedures, divide exposed food items into groups based on protection of item at time of exposure. These groups establish priorities based on ease of decontamination and the ability to monitor the food.

(1) Group I—Canned or packaged items exposed only to a chemical agent vapor.

(2) Group II—Canned or packaged items that are contaminated on the outside with a liquid chemical agent, a biological agent, or radioactive fallout.

[J-2]

(3) Group III—Unpacked or poorly packaged items that have been exposed to any NBC agent.

(4) Group IV—Food contaminated through the food chain.

#### J-2. Protection of Food from Contamination

An adequate defensive posture for a chemical attack will also protect food against biological contamination and radiation fallout.

a. Operational Rations. Operational rations include, but are not limited to, MREs; unit group ration (UGR), A; unit group ration, heat and serve; and medical diet supplement.

(1) Packaging materials and storage methods normally protect these rations. The packaging and packing of operational rations protect the contents from deterioration. As a result, the contents are protected from moisture, to include chemical liquids, chemical vapors, and biological agents. Operational rations delivered to an AO will usually have increased levels of packaging and/or packing protection. Operational rations are substantially protected while contained in the shipping cases, especially if protected with an overlay of fiberboard, shrink wrap, or film wrap.

(2) Enclosed storage is used whenever possible. Refrigerated warehouses, cold storage rooms, and even prefabricated refrigerators and trailers provide excellent protection. Underground shelters, caves, and tunnels that can be made airtight provide maximum NBC protection. Buildings provide protection depending on how well they can be closed and sealed. The basement of a building is a good storage place. However, keep in mind that chemical vapors tend to seek out low-lying areas. Storing rations indoors will protect them from liquid droplet and fallout contamination unless the building is damaged by an attack. Complete protection against chemical vapors is only offered by airtight closed spaces like cold storage facilities.

(3) Chemical protective measures are to be integrated into daily logistical operation to avoid the contamination of operational rations. Maximum use is made of alarm and detection equipment, overhead shelter, shielding materials, and protective covers. Back up stocks of operational rations should be dispersed to minimize the risk of destruction or contamination.

(4) An NBC Protective Cover or similar equipment will help greatly. The NBC Protective Cover is discarded and replaced upon becoming contaminated; it reduces overall decontamination requirements; and it improves the survivability of supplies and equipment. The NBC Protective Cover provides 24-hour protection against liquid chemical contamination. Detection paper used on the NBC Protective Cover will rapidly identify a contaminated cover.

b. Bulk and Fresh Foods.

(1) Field expedient or improvised storage may be the only choice available under high-risk conditions. Expedient storage for food supplies may be a natural or man-made depression lined to protect [J-3] contents against moisture, and then covered with earth and sod. The earth gives good protection against all forms of chemical or biological contamination and nuclear fallout.

(2) Foods are only stored outdoors or in partially protected areas when absolutely necessary. Only cases of foods packed in cans, bottles, or airtight foil or film wraps, and foods packed in sealed boxes or multilayered wrappings can be subjected to exposed storage. Partial protection is provided by open sheds, temporary roofing, or tents. When subsistence must be stored in the open, give as much protection as possible. Protection material may include NBC Protective Covers, tarpaulins, tarpaulin sheds, or any other available covering such as plastic sheeting. Tarpaulins and other treated or waterproof coverings do not prevent contamination by chemical vapors, but they do reduce contamination from liquid agents. Canvas will keep out more than 95 percent of liquid contamination for a short period of time after the attack. The canvas must be removed soon after the attack to prevent the agent from seeping through onto the subsistence; placement of spacers between the covering and the food will greatly reduce this problem. Even the thinnest material will offer some protection and is better than nothing at all. Therefore, food supplies must be covered by whatever material is available.

#### J-3. Nuclear

a. Contamination.

(1) Following a nuclear detonation, food can become contaminated in three ways:

- Direct contamination. Direct contamination results by fallout collecting on plants, animals, and stored food (surface contamination). Fallout has two effects. First, it produces a gamma radiation field over the fallout area. Second, it contaminates the surface of anything on which it is deposited. The whole-body gamma irradiation hazard to an individual far outweighs any potential hazard from food contamination. The basic rule is: If you can safely be in the area to salvage the food, then the food salvaged is safe to use (although slightly contaminated).
- Indirect contamination. This form of contamination can be spread throughout the food chain. Humans can ingest contamination by eating plants that have absorbed radioactive isotopes; products (milk or meat) from animals allowed to graze on contaminated pastures; or fish from contaminated water.
- Induced radiation. It is possible that food will be exposed to sufficient neutron flux (an increase in the number of free neutrons) as the result of a nuclear explosion to produce considerable induced radioactivity in food without it being destroyed by blast and heat. This is possible with enhanced radiation weapons in the energy range of 1 KT where the radiation kill radius exceeds the blast destruction zone. The elements that are most prominently involved are sodium, potassium, sulfur, copper, bromine, zinc, and especially phosphorous. Thus, in an area of induced radiation, foods requiring the most caution are dairy products, high salt content foods, dry beans, raisins, and ready-mixed cake and biscuit flours. The radioactivity has a short half-life; therefore, the radiation will decay very rapidly. It should be possible to consume foods containing induced radiation within a week or two. Cans, particularly those with "C" enamel, may incur a high level of induced radiation (from zinc in the enamel, not from iron in the can). [J-4] Glass, because of its high salt content, will show very high levels of activity; clear glass will turn brown. Container radioactivity has no bearing on the food, it is safe to use. The radioactivity is not transferred to the contents. No significant toxic by-products are formed in the exposed canned food.

(2) Consumption of food contaminated with radioactive fallout may cause a risk of radiation injuries from internal radiation; that is, radiation from radioactive sources within the body. Most isotopes will pass through the digestive tract or be excreted very quickly. However, the intestinal tract may receive a considerable dose. Some isotopes are more hazardous because they are absorbed from the digestive tract and enter the metabolism of man and animals.

- Strontium-89 (Sr-89) and Strontium-90 (Sr-90) are beta emitters and have half-lives of 51 days and 28 years, respectively. Therefore, Sr-90 is the greatest radiation hazard in the long term. These two isotopes are absorbed in the body and used in the same way as calcium. They accumulate in bone, where bone marrow with its blood forming cells is vulnerable. Milk and other dairy products are the primary sources of Sr-89 and Sr-90 in the human diet.
- Iodine-131 (I-131) is a beta and gamma emitter and has a short physical half-life of approximately 8 days. It is efficiently absorbed and used by the body. Iodine-131 will contaminate plants that will be eaten by grazing animals. Smaller amounts can also be absorbed by breathing contaminated air. Cattle will excrete a large amount of I-131 in milk. Milk and other dairy products are the primary sources of I-131 intake. One can also get smaller amounts by eating contaminated fruits and vegetables. Iodine-131 will be concentrated in the thyroid gland. The intake of I-131 will have its greatest impact the first few days to weeks following a nuclear explosion.
- Cesium-137 (Cs-137) is a beta emitter and has a half-live of 30 years, but is eliminated relatively quickly from the body. The biological half-live is 70 to 140 days. Cesium-137 is found in most tissues of the body, but it will concentrate in muscle tissue. Cesium-137 is absorbed and used the same way as potassium. Meat and milk are the primary sources of Cs-137. Much precipitation, lack of minerals in the soil, and extensive cultivation increase the plants' absorption of Cs-137; thus, the contamination of plant products.

(3) Operational rations are safe when surface decontamination is performed before breaking the package. Operational rations stored close to ground zero may become radioactive from induced radiation. It is more likely, however, that the food will be damaged or destroyed by the blast and thermal effects of the nuclear explosion.

(4) Bulk and fresh food stored in the open without protection will be contaminated. Decontamination is very difficult and time-consuming. Efforts should be made to ensure proper packing to prevent food contamination from radioactive fallout. Packing made from hard and nonporous materials, such as plastic or multilayer cardboard with a smooth surface, should be used. In addition, storage facilities should be enclosed to avoid the entry of fallout. Any material used as a protective cover will give some protection against nuclear fallout. Protection against induced radiation, blast, and thermal effects requires a hardened shelter or underground storage.

(5) Food supplies require protection throughout the chain of production or procurement. Protection of the civilian-based food supply includes countermeasures along the production chain. Meats [J-5] and milk are the most vulnerable products because of the possibility for concentration of radioactive isotopes (Strontium, Cesium, and Iodine). The primary, and possibly the only, protection of animal products is to keep the animals indoors and to avoid contaminated fodder. Immediate slaughter of food animals is recommended if there is a shortage of uncontaminated fodder. Also, food animals exposed to fallout should be considered fit for consumption and slaughtered using routine procedures. Unharvested crops cannot be protected.

b. Inspection and Monitoring.

(1) Fallout close to ground zero, especially after a surface burst, may be visible as dust. The presence of dust is an immediate indicator of contamination. Fallout on unprotected food produces a grittiness that is unpleasant and warns against eating the food. The degree and means of food protection (packaging and storage faculties) must be considered. Food in a building that remains intact should not receive enough contamination to be dangerous when eaten.

(2) Veterinary units have the AN/VDR2 Radiac Set and UDR13 dosimeter to conduct ground or aerial surveys for gamma radioactive contamination levels in an area. The measurement of the external gamma radiation in the fallout area is an indication, but not a quantitative measure, for the degree of hazard from food contamination. These units also use the AN/VDR2 Radiac Set for point detection of gamma and beta radiation sources. Food monitoring is conducted in an area with low background radiation. If the storage area is contaminated, the food must be moved to a cleaner area for monitoring. With the AN/VDR2, the initial food monitoring is performed with the probe cover in place and the probe passed approximately 6 inches from the surface. If the reading is twice the background dose rate, the food is considered contaminated. If the reading is not above the background level but contamination is still suspected, place the probe closer to the food with the beta probe cover off. Monitor meat and fish with the probe cover off; pass the probe approximately one-half inch from the surface of the food.

(3) Monitoring food contaminated through the food chain is more complicated; depending on the detection instrument used, special procedures must be followed. Gamma and beta emitting radionuclides in small volumes may be detected using radiac sets such as the AN/VDR2; however, alpha emitting ones cannot. They are rough instruments and may be used only for screening surface contaminated food. To evaluate the hazards; the isotopes contributing to the radioactivity must be identified. Surface contaminated food will contain a mixture of isotopes with some more hazardous than others, depending upon whether they are used by the body. Milk will contain mostly I-131, Cs-137, Sr-89, and Sr-90. Meat and fish will contain mostly Cs-137. To verify I-131, Cs-137, Sr-89, and Sr-90 contamination, samples must be sent to laboratories equipped to analyze the samples.

(4) All newly selected food supplies must be surveyed. Begin continuous monitoring immediately following receipt of a fallout warning, or when increased levels of radiation are detected by periodic monitoring.

(5) Periodic monitoring is needed to establish baseline levels of background radiation in the environment and various food products. This monitoring is performed during peacetime, when possible, and throughout the time US forces are deployed in a TO.

[J-6]

NOTE

The AN/VDR2 is being replaced by the AN/PDR77 Radiac Set.

c. Decontamination. There are two methods for nuclear decontamination: aging and removing. Aging is the process of allowing natural radiation decay to occur. The time necessary for this decay to take place depends upon the isotopes present; each has a different decay rate (half-life). Aging may not be possible when there is a short food supply. In some instances, such as with induced radioactivity, it may be the only way to decontaminate. Removing nuclear contamination from areas, personnel, food, or moving equipment to another location eliminates the immediate hazard. To determine which decontamination method is required, food supplies are divided into groups. See Table J-1 for additional information on food items and decontamination.

(1) Group II—Food in sealed and dust-proof packing such as cans, jars, fiberboard, and cellophane. These products are easily decontaminated by removing the radioactive dust covering the packing; brush, wash with soap and water, or remove the packing (depending on the type of packing material). If radiation is still detected after removing the dust, repeat the brush/wash procedure and remonitor. If radiation is still present, the food itself is then considered radioactive (induced radiation) and is unfit for consumption. Decontamination of induced radiation is possible only through aging. After aging one to two weeks, the food should be safe for consumption. After surface decontamination, the contents are safe to eat unless the food has induced radiation.

(2) Group III—Unprotected food. The method chosen to decontaminate unprotected food items will depend upon whether or not the food supply is critical. If the food supply is not critical, the contaminated items are isolated and allowed to decontaminate by aging. If the food supply is critical, food with surface contamination can, in principle, be decontaminated by removing the contaminated surface, or by washing.

(3) Some products can be decontaminated by washing, peeling, or trimming the outer skin or leaves. Decontaminate potatoes and hard-skinned fruits and vegetables by washing or scrubbing under running water, followed by peeling or scraping, then washing again. Potatoes, carrots, beets, and turnips can be washed at the supply depot. However, do not wash beans, rice, and onions until they are delivered to the field kitchen; washing reduces their storage quality and shelf life. Citrus fruits, pineapples, corn, peas, beans, melons, pumpkins, cabbage, and nuts can be peeled. Decontaminate cucumbers, tomatoes, cherries, cranberries, grapes, pears, plums, and thin-skinned squash by soaking in a water or detergent solution and rinsing with vigorous agitation or brushing. Apricots, peaches, most berries, asparagus, broccoli, and leafy vegetables cannot be satisfactorily decontaminated because of fuzzy surfaces, irregular shapes, or small size, which makes washing difficult.

- Fresh carcass meat, sausages, and fish can be decontaminated by several washings with cold water. The exterior layer of the food item is removed if radioactivity is still present. There is, however, a risk of contaminating the inner parts of the foodstuff in the process. Cooking with several changes of water is the last step in decontamination.

[J-8]

- Decontaminate hard cheeses, margarine, and butter by cutting off the outer layer to a depth of 2.5 to 3 cm.
- Let cooking oils stand for 3 to 5 days, then pour off the contaminated layer; use a funnel to control spillage.
- Nonperishable items that are hard to decontaminate, such as flour, sugar, and salt, can be set aside allowing natural radioactive decay. When supplies are short, dilute the contamination by mixing with uncontaminated food. This will reduce the total amount of radioactive exposure in foods prepared using these contaminated items.
- Decontaminate air permeable, double-sacked goods by removing the outer sack. If the inner sack is free of radiation, double sack the food again to restore protection. However, when contamination is present on the inside bag, the food in contact with the bag is likely to be contaminated. Three methods can be used to handle this type of contaminated product. The easiest method involves spraying the bag of dry goods (except sugar or salt) with water. This will wet a layer of the food inside the bag. The wet layer can be removed when the bag contents are emptied. The uncontaminated contents are scooped back into clean packaging. Another method involves using melted paraffin to uniformly coat the outside of the bag. The paraffin solidifies after 30 to 40 minutes, and then the bag with the radioactive contamination can be removed from the contents. Although this method will seal the radioactive substance in the wax, it probably will not remove the layer of contaminated food product inside the bag. For the third method, form a piece of sheet metal into a cylinder the same height as the bag and 4 to 6 cm smaller in diameter. Insert the cylinder into the bag, then remove the top 3 to 4 cm of the contaminated product. Carefully scoop the remaining product out into a clean sack. With the cylinder still in place, fold the bag down catching the contaminated product on plastic sheeting, or a tarpaulin. When using this method, mixing the contaminated portion with the uncontaminated portion is a problem. Check for contamination remaining in the product.
- Boiling or cooking has no effect on radioactive contamination.

(4) Group IV—Food contaminated through the food chain. It is not practical to decontaminate this food. Meat and milk are the two most common foodstuffs contaminated in this way.

- Milk may be decontaminated to a safe level by a complicated ion exchange process. The I-131 activity will decline rapidly during storage of milk and milk-products, although the Cesium and Strontium activity will remain almost constant for years. In an area with high-level fallout, milk is withdrawn from human consumption. The duration of withdrawal will be dependent upon the type of fallout and levels.
- Meat may be decontaminated to a safe level by soaking in water or brine. Cesium is loosely bound in the meat. By repeated soaking of meat cut in small pieces, most of the Cesium activity will be removed. Traditional meat preserving, such as salting with brine, will remove up to 60 to 70 percent of the Cesium activity. See Table J-2.
- Fruits, vegetables, root crops, and grain products may also contain hazardous amounts of radioactivity if ingested.

[J-9]

(5) Food animals. Food animals that have been exposed to fallout should be considered fit for consumption and slaughtered using routine inspection and slaughter procedures. In those cases where the animal has been exposed to fallout, but is not scheduled for immediate slaughter, the radiation burden can be reduced by moving the animal to an uncontaminated area (barn if available) and washing it with soap and water. Mild radiation sickness does not necessarily mean that the animals cannot be used for food. If the animals have been exposed to an internal radiation hazard, the meat can be eaten if the internal organs are discarded. Chickens that have eaten radioactive material may lay contaminated eggs, but most of the radioactivity will be concentrated in the shells. The white and yolk will be free of harmful amounts of radiation and can be eaten. Chickens will not lay eggs if the radioactive body burden is large enough that their eggs are unfit to eat.

d. Considerations When Decontamination is Not Possible. When food cannot be decontaminated, sealing the product in a wrapping material or container may be needed. Sealing the product can reduce or shield the emanation of the contamination and/or fix the contamination in place. The hazard from [J-10] contaminated food is small compared with that from external gamma radiation. Hungry people or animals should not be denied food because of possible fallout contamination. It is not practicable or desirable to preset maximum permissible limits of gross fallout radioactivity as a basis for judging whether or not food should be used. Common sense must be applied in establishing priorities for distribution of available food. For example, use the least contaminated and the most protected food first; hold milk products for 1 to 2 weeks before use.

#### J-4. Biological

a. Contamination. Biological warfare agents exist in the form of toxins and microorganisms. The normal packaging and packing of food (to protect against moisture, dust, and bacterial or other contamination) provides protection against most biological agents. The exception may be toxins and biologically derived substances. However, the protective methods used for chemical agents will also protect against toxins and derived substances. Food in freezers, refrigerators, and in refrigerated trucks or rail cars will be safe if these containers remain sealed until the outer surfaces are decontaminated.

(1) It is unlikely that a biological agent will affect the appearance, taste, or smell of the food enough for the change to be apparent.

(2) Packaging and packing materials are not life supportive to pathogenic agents and are, therefore, self-decontaminating with the exception of spore-forming organisms.

(3) Most operational rations are packaged in metal containers, or encased in heavy aluminum laminated plastics that can withstand boiling water; also, they are impervious to arthropod penetration. This food is highly resistant to biological agents.

(4) The use of unpackaged items (unwrapped meats, fresh fruits, and vegetables) should be restricted; use only operational rations. Unprotected fresh food stored in the open and close to the source of dissemination will become contaminated.

b. Detection.

(1) Rapid identification of agents used is absolutely essential to implement effective countermeasures. Agent identification must be achieved quickly; it is the first step in answering critical management questions. What adjustments must be made in food preparation and distribution? What are the essential countermeasures? What is the expected outcome of the incident?

(2) Samples of food that are suspected of being contaminated are transported to the designated supporting laboratory. Samples must be accompanied by a description of the samples, the sample collection procedures, and the circumstances, which prompted the collection. The designated medical laboratory in the TO will provide a field confirmation identification of the agent(s). Designated CONUS laboratories accomplish definitive identification. See Appendix B for sampling procedures.

[J-11]

NOTE

New biological detection equipment is under development that will enable units to conduct presumptive identification of biological warfare agents. However, samples must also be collected and processed as described in Appendix B.

c. Decontamination.

(1) Food contaminated with toxins is handled in the same manner as food contaminated with chemical agents. Food contaminated with microorganisms is handled in the same manner as when contaminated with the more common foodborne disease-producing microorganisms.

(2) Several methods are available to decontaminate food items contaminated with biological agents. The following decontamination methods are considered to be the minimum. See Table J-1.

(3) Group II food that is sealed in containers that are resistant to the passage of biological agents requires only that the exterior of the container be decontaminated. Decontamination of these items is as follows:

(a) For containers made of metal, glass, plastic, or porcelain:

1. Thoroughly wash the container in potable water and soap, or in a disinfectant solution. If the water used for washing is contaminated, the soap and water wash may increase, not reduce, the contamination hazard. After which, the food containers are immersed in a disinfectant solution for 30 minutes (see Table J-3); then rinsed with potable water, if available and time permits. Chlorine solutions are not as reactive or corrosive as DS2.

2. Place the containers in boiling soapy water for 15 minutes; then rinse with potable water.

NOTES

1. The chemical field decontamination kits do not meet the requirements to decontaminate food supplies exposed to biological agents.

2. The same procedures should be followed even if there is only suspicion of a biological warfare attack.

(b) Thoroughly wipe containers that will not withstand soaking with a cloth soaked in a chlorine detergent solution. Remove the food from the container and place it in Group III.

[J-12]

(c) Metal or glass containers determined to have trichothecenes (Yellow Rain) present can be decontaminated using DS2. Allow a contact time of 5 to 30 minutes for the DS2 to neutralize the toxin. Then rinse the container with potable water.

(4) Group III food items that are not protected by the packaging material are decontaminated or disposed of as follows:

(a) Decontaminate foods that can be peeled or pared by immersing them in a disinfectant solution for 30 minutes, and then rinsing them with potable water (see Table J-3). Peel or pare the items after decontamination, then wash and, if appropriate, cook before eating.

(b) With the exception of certain heat-stable toxins, heat is the most practical means of decontaminating food. Several heating methods may be used, but the method chosen depends upon the type of food to be decontaminated. The key is to apply as much heat as possible without rendering the food unfit.

1. Cook in a pressure-type cooker with 15 pounds of pressure at 250°F (121°C) for 15 minutes.

2. Cook in a low-pressure cooker at 228°F (109°C) for 1 hour.

3. Bake bread or related items at 400°F (204°C) for 40 minutes.

CAUTION

Bread made with toxin-contaminated flour (especially with trichothecenes) is still toxic.

4. Bake or roast meat at 325°F (163°C) for 2 hours.

5. Boil for at least 15 minutes when no other method is available.

(c) Although decontamination methods are provided above, vegetables such as lettuce, broccoli, and cauliflower, or unwrapped meats that have been exposed to biological agents should not be eaten.

(d) Foods, such as butter, ice cream, and bread that will not withstand any of the above treatments must be destroyed.

(5) Established meat inspection procedures are followed when animals exposed to biological agents must be used for food. The meat must be thoroughly cooked.

#### J-5. Chemical

a. Contamination.

(1) Contamination of foodstuffs by a chemical agent may occur at any point on the battlefield. This contact may render the food unpalatable also. In many cases, decontamination is difficult, thus, emphasis must be placed on protection. Keep food supplies covered at all times. Take special precautions to protect food that is not packed in protective packages. Unprotected food, forage, and grain supplies may be so contaminated that their consumption will produce gastrointestinal irritation, or systemic poisoning. Nerve agents, vesicants, and arsenicals are the most dangerous. Field concentrations of phosgene, hydrocyanic acid, irritants, and smokes will seldom be high enough to cause serious food contamination. The effect of CK on food is not known. As a precaution, foods exposed to CK should be considered toxic.

(2) The effects of chemical agents on food depend on the nature of the agent and the type of the food. The extent to which chemical agents penetrate food also depends on the amount, form of dispersal (liquid [droplet size], or vapor) and duration of exposure. Nerve agents and mustard will penetrate deeply into unprotected fatty foods and will readily penetrate granular products such as grain and sugar. Liquid food products can be completely contaminated. Arsenicals readily hydrolyze to poisonous arsenical oxides in some foods. Foods can be divided into three categories based on their water content, fat content, and crystalline structure:

(a) Foods having a high water content, a low fat content, and/or a crystalline structure (fresh vegetables, fruits, sugar, salt, and eggs) will absorb mustard and nerve agents, either as a liquid or as a vapor. Nerve agents will be hydrolyzed slowly.

(b) Foods having a low fat content and an irregular (amorphous) structure (flour, bread, grain, rice, cereals, dried fruits, dried vegetables, tea, coffee, peas, and beans) readily absorb mustard and nerve agents in liquid form. As a vapor, these agents are absorbed to some extent, but are easily removed by airing.

(c) Foods having a low water content and a high fat content, such as butter, fat, fatty oils, ham, cheese, milk, bacon, fatty meat, and fish, absorb mustard and nerve agents such that removal of the agents is virtually impossible.

[J-14]

(3) Chemical agents can be physically and chemically absorbed into food. In addition to the toxic effect, they often adversely affect taste, smell, and the appearance of the food. However, chemical agents can cause the food to become very toxic without causing any other changes in the food. Table J-4 shows the effects of a number of chemical agents on food. Since food can be contaminated without any outward change in appearance, the possibility of contamination must be assumed in a chemical agent environment. Treat the food with the same precautions as established for known contaminated items.

(4) The protective properties of packaging materials are dependent upon a number of factors. The factors include the form of the agent (liquid versus vapor); concentration and exposure time; weather (temperature, wind speed, and humidity); and packaging material (the type of material, thickness, and the presence of folds, tears, and small holes). Even the thinnest material will offer some protection and is better than nothing at all. Therefore, always cover food supplies with whatever material is available. Table J-5 summarizes the protection values of various packaging materials against vapors and liquids.

(a) Operational rations are substantially protected while contained in the shipping cases and especially if stored in the original palletized unit load with an overlay of fiberboard, shrink wrap, or film wrap. The worst case is pallets of subsistence contaminated by liquid droplets during an attack. After the attack, high vapor concentrations will exist in the vicinity of the palletized loads. If the outer barrier is permeable such as fiberboard, it is possible that a liquid agent can seep through the overlay fiberboard and contact the shipping containers in liquid form. Normally, with seepage resistant materials, such as shrink wrap as the outer barriers, only the vapors of the agent are found within the pallet.

(b) While MREs are stored, the food is protected by up to six layers of material. Multilayer barriers result in a complex diffusion process of the agent from the outside towards the interior. Vapor penetration into nonhermetically sealed spaces is a simple gaseous diffusion process. Permeation through packaging is a much more complex process regardless of whether the challenge is a liquid or a vapor.

1. Liquid is adsorbed into permeable materials such as fiberboard or chipboard. With permeation-resistant materials (such as shrink wrap), the agent dissolves into, seeps through, and then desorbs from the barrier material. Shrink wrap provides adequate protection. Fiberboard sheathing provides adequate protection against mustard agents, but not against nerve agents.

2. The low-density polyethylene used to construct the menu bag can absorb chemical agents and possibly toxins. If the menu bag is removed from the shipping container and is exposed to liquid contamination, enough agent may pass through the bag to create a health hazard. Keep MREs in the shipping container until issued to the soldier. The menu bags should then be kept under the same degree of protection as the soldier.

3. The aluminum-laminated materials used to construct the MRE (retort and nonretort) pouches protect food from chemical contamination if hermetically sealed. The only item in the MRE meal bag that is not adequately protected is the spoon.

(5) Mylar and cellophane are resistant to chemical agents.

b. Detection.

(1) Currently, a field method for detecting chemical agent contamination in food does not exist. Contamination is not always spread evenly throughout food; this makes it impossible to take a single sample and determine the presence or absence of chemical agents in the entire lot. Additionally, standardized laboratory tests have not been developed for determining levels of chemical agents in food. Until a specific method to detect chemical agents in food is available, reliance will have to be made upon determination of contamination, or lack thereof, on the packaging material; the integrity of the packaging material; the protective qualities of the packaging material; and the penetration characteristics of the suspected chemical agents.

(2) Food may become toxic without any change in outward appearance. Never taste or smell food to determine if contamination is present in food.

(3) Veterinary and subsistence units have the following equipment available to detect chemical agents in the field:

(a) The M8 Automatic Chemical Agent Alarm System consists of the M43 detector unit and the M42 alarm unit. The detector unit is a portable, automatic, point-monitoring device that is designed to be hand carried from point to point. The M8 is used to provide early warning of a toxic agent position and detects the presence of chemical vapors and aerosols. The M43 detects all nerve, blood, and choking agents, and some blister agents. The M43A1 (the replacement for the M43) only detects nerve agents.

(b) The M256 Chemical Agent Detector Kit detects and identifies nerve, blood, and blister agents. The M256 is the most sensitive of the chemical agent vapor detectors available. However, it is not a continuous, real-time monitoring system. It requires 15 to 20 minutes for sampling and analysis.

(c) The ABC-M8 VGH Chemical Agent Detector Paper can detect and differentiate between nerve and blister agents by color change. It is intended to be used by blotting and wiping surfaces suspected of contamination. The M8 paper will respond with a visual color change in 10 seconds or less.

(d) The M9 Chemical Agent Detector Paper will detect liquid nerve (G & V) and blister agents (H & L), but will not identify the specific agent or differentiate between nerve and blister agents. The M9 tape is sensitive to droplets as small as 100 μ, and will respond with a visual color change in 10 seconds or less.

(4) All subsistence in a chemical attack area are considered contaminated until a survey can be conducted, preferably by veterinary and chemical personnel. Personnel must be at MOPP Level 4 while conducting the survey. Concentrate the initial portion of the survey on the adequacy of the storage facility and other protective measures in preventing chemical agent contact with subsistence items. The area surrounding the storage facility is examined for the presence of animals, rodents, birds, and arthropods acting unusual, or dead in unusual numbers. If animals are present and assistance is required in identifying the NBC agent, specimens can be collected and submitted to the area medical laboratory. Damage such as broken windows, holes, or loss of structural integrity of the storage facility is noted. This information combined with knowledge of the agent form (liquid or vapor), type of agent (which will indicate the degree [J-17] of persistency), and approximate time of attack will provide a risk assessment. Liquid agents should not significantly penetrate an intact facility, but may produce vapor contamination by off-gassing.

(a) Upon entering the storage facility, the M8 can be used to determine the presence of chemical vapors. However, precautions must be taken. The M42 alarm is not to be used inside shelters, vehicles, vans, or other interior modes. Therefore, when checking food storage facilities, the alarm unit must be left outside, turned off, or disconnected. Do not tilt the M43 detector more than 45 degrees (because of the liquids it contains). This is not a problem with the improved M43A1, but the M43A1 requires attachment of an exit port filter when used indoors. The M256 Chemical Agent Detector Kit can be used to sample the air.

(b) Pre-position M9 chemical agent detector paper in food storage areas; especially on the least protected pallets and in areas where droplets may enter, such as near doors or windows. Examine the M9 paper for indications of liquid chemical agents. If the M9 paper is positive, or if the packaging materials show the presence of liquids or stains, use the M8 detector paper to determine the type of the agent. If an agent is not indicated by the detector paper, then the amount of agent present will be insufficient to cause secondary contamination when the outer package is removed.

(5) Detection procedures become more complicated if a chemical agent has penetrated or permeated through the packaging and packing materials. Unless liquid has seeped through the cardboard, any agent in the interior of the shipping case will be in a vapor form. Liquid seeping should be obvious. The sampler-detectors in the M256 Chemical Agent Detector Kit do not have an aspirator for sampling the interior of the case. However, there are several procedures that can be used. One is to open the case, place the activated sampler-detectors inside the case, and then reclose the case. Another is to punch holes in the case, place the activated sampler-detector over the holes, and cover the sampler-detector with an empty box or can (open end down) to concentrate the vapors escaping from the case. Alternatively, remove the food from the case and place it in a plastic bag with the sampler-detectors to concentrate the vapors. These procedures require two sampler-detectors; one for blood agents and one for nerve and blister agents. Neither method is very sensitive in low concentrations of vapor as is expected to be present inside shipping containers. A better method is to modify the M43 detector with a field expedient probe of Teflon tubing attached to the detector's air inlet. Insert the open end of the tubing into a hole in the case or package to sample the interior air. When available, the improved chemical agent monitor (ICAM) can be used; its design will allow aspiration of air from inside shipping cases. The ICAM can also be used to detect and identify liquid agents on a surface provided the agent is vaporizing in sufficient quantity. The ICAM gives a visual representation of a hazard evaluation.

c. Decontamination.

(1) Decontamination is only required for contamination remaining 10 minutes or longer. Decontamination efforts on subsistence items will normally be limited to removal of the containers and carton overwrap material.

(2) The need for decontamination is primarily dictated by the type of chemical agent used. The method of decontamination selected will depend upon the type of packaging material used and the urgency with which the food is required.

[J-18]

(3) Food supplies in storage are not likely to be seriously contaminated if reasonable protection precautions are taken. For this reason, large supplies of food are not to be condemned as a whole simply because they have been exposed to possible chemical contamination. A prompt and careful survey of the supplies may reveal that only a few items have been contaminated to a level that decontamination is required. Prompt segregation of the heavily contaminated portions will prevent, or minimize, contamination of the remainder. Foods without protective packages constitute the major difficulty.

(4) Individual decontamination is performed by each soldier on those subsistence items in his possession at the time of the attack. Individual decontamination is limited to operational rations that are in original, intact containers. Unit-level decontamination is performed by unit personnel under the supervision of unit NBC personnel. Support decontamination is attempted at major subsistence storage facilities. Again, decontamination is limited to packing material. Decontamination of food itself is only attempted in emergency situations when alternative supplies are not available.

(5) Start decontamination operations with the easiest method and proceed to the most difficult. This allows for the removal of a relatively large portion of the contamination in a minimum of time. The simplest procedure is to allow the materials to age and air ("weather"). Substantial self-decontamination will occur with most agents. Exceptions are thickened mustard, thickened GD, and VX. Table J-6 provides the length of time for which contaminated subsistence supplies may present a contact hazard. Weather elements that affect decontamination are—

(a) Warm temperatures speed liquid agent off-gassing and hasten the dispersion of chemical agents into the air.

(b) High winds rapidly disperse chemical agent vapors and speed off-gassing from surfaces.

(c) Moisture causes chemical agents to react with water to form nontoxic or less toxic chemicals. Heavy rain or rain of long duration can aid decontamination by mechanically removing chemical agents.

(d) Even in cold weather, direct sunrays warm surfaces above the air temperature and hasten the off-gassing and decomposition of chemical agents.

Table J-6. Persistency of Selected Liquid Chemical Agents

| WEATHER CONDITIONS
--- | ---
AGENT | SUNNY, AROUND 20°C, LIGHT BREEZE | WET AND WINDY, AROUND 10°C | CALM, SUNNY, LYING SNOW, AROUND -10°C
MUSTARD(HD) | 2-7 DAYS | 1/2-2 DAYS | 2-8 WEEKS
TABUN(GA) | 1-4 DAYS | 1/2-6 HOURS | 1 DAY-2 WEEKS
SARIN(GB) | 1/4-4 HOURS | 1/4-1 HOUR | 1-2 DAYS
SOMAN(GD) | 2-1/2-5 DAYS | 3-36 HOURS | 1-6 WEEKS
NERVE(VX) | 3-21 DAYS | 1-12 DAYS | 1-16 WEEKS

[J-19]

(6) Active decontamination is attempted only when weathering will not decontaminate the packaging material in sufficient time. Decontamination procedures can be enhanced by using heat to vaporize the chemical agent; by reaction with decontaminants; or by removing with hot soapy water.

(a) The simplest (standard) decontamination materials are water and detergents. An effective decontaminant is hot water used with the addition of soap or detergent and scrubbing. Commercial abrasive powdered cleansers are effective decontaminants for many surfaces (metal, glass, Formica), but not wood or soft plastics.

(b) Water can be used to flush chemical agents from surfaces. High-pressure application produces a better cleansing action than low pressure. If the surface has absorbed the agent, flushing will remove the surface contamination, but will not affect the agent that is absorbed.

(c) Soaking contaminated items in boiling water is an excellent decontamination method for some agents. Water alone will not be sufficient to decontaminate all chemical agents. Soaking in warm or cold water may reduce the contamination slightly; however, the hazard may not be reduced sufficiently even after prolonged soaking. If hot water is not available, or if it might cause damage to the item, other methods of decontamination should be considered, such as decontaminating solutions or a caustic solution followed by thorough rinsing.

(d) Fibrous materials such as cloth and canvas are best decontaminated by washing and scrubbing.

(e) Glass, metal, porcelain, and plastic surfaces are best decontaminated by using hot water or hot soapy water. Some toxic materials are readily removed with no more than slight abrasion or brushing.

(f) Painted, varnished, and waxed surfaces are generally smooth and nonporous. Dust and liquids are readily removed by wiping, brushing, or vacuuming. Absorbed materials are removed by hot water, detergent, or complexing agents. None of these surfaces stand up well to heavy abrasive techniques. Agents can be attacked and removed by caustics, acids, and organic chemicals. Some of these surfaces readily absorb agents, so weathering following decontamination is advisable.

(g) Rubber is a porous material that can absorb agents. It is not easily decontaminated by abrasive techniques. Warm, soapy water used with brushing is effective since it removes some absorbed contamination. Strong acids, alkalies, and organic solvents may deteriorate and decompose rubber articles.

(7) Operational rations are the primary rations issued; always issue uncontaminated stocks first. This allows for decontamination of contaminated stocks without interrupting supply support. Normally, contaminated stocks are not issued. The decision to issue contaminated items is based on the tactical situation, criticality of the items, type and extent of contamination, and the time and resources available for decontamination. Decontamination efforts on subsistence items are limited to the containers and carton overwrap material.

(a) The MRE retort and nonretort food pouch may be decontaminated with soap and water wash. The chemical agents will be removed by the solutions.

[J-20]

(b) Semipermeable materials (polyethylene menu bag, shrink wrap, and film wrap) may have chemicals deposited not only on the surface, but also dissolved into the matrix of the material. The chemicals can be removed from the surface by washing with hot soapy water, but contaminant dissolved in the material is not removed. The remaining agent can only be removed by weathering which can be accelerated through the use of heat and sweeping the surface with air.

(c) Fiberboard is both sorbent and permeable and acts like a blotter. Liquid decontaminants can force the contaminant further into the fiberboard. Any attempt to decontaminate fiberboard would be futile. The only alternatives are to remove the fiberboard, or to allow it to weather.

(d) Palletized unit loads of MRE and UGR outerwraps can be decontaminated through the aid of a forced clean air sweep in 4 to 5 days, compared to 3 weeks or more under natural conditions without a forced air sweep.

(8) Contaminated food supplies are only handled by personnel trained in decontamination methods and in MOPP Level 4. Contaminated food items are divided into three groups as described below (see Table J-1 for additional information).

(a) Group 1 consists of canned and unopened packaged items which have been exposed only to agent vapors. Most items in this group will be safe to issue after a brief period of outdoor airing to remove clinging vapors. Table J-7 lists the decontamination procedures for packaging materials contaminated with nerve agents, mustards, and arsenicals.

BOARD, MULTILAYER |  | 24 HOURS.
BAGS.
CARDBOARD, | LIQUID | CONTAMINATED CONTENTS—
POLYETHYLENE. |  | TREAT AS UNPACKAGED FOOD.

(b) Group II consists of canned and unopened packaged items which have been contaminated with a liquid chemical agent.

1. Attempts to decontaminate porous packaging materials, such as cardboard or wood, are likely to be unsuccessful and may result in spreading the contamination. The best procedure in [J-21] handling such items is to strip off the outer contaminated coverings and examine the inner layer to see if penetration of the agent has occurred. If it has, continue stripping off layers until an uncontaminated layer is reached and place it in Group I. If the agent has penetrated to the food, place it in Group III.

2. Food in cans or in other sealed, impermeable containers is not in danger of chemical contamination. Because contamination is confined to the outer surface of the sealed container, decontamination is accomplished by: immersion in boiling, soapy water for 30 minutes and rinse; immersion in boiling water for 30 minutes; spray with DS2; or to wash in hot soapy water, rinse, and aerate. Under no conditions should contaminated containers be opened before they have been decontaminated and monitored.

3. Supertropical bleach and DS2 can be used on the polyethylene menu bag for up to 24 hours without a significant change in appearance, tensile properties, and size of the plastic. The use of DS2 will cause significant degradative changes to most other plastics, while STB will cause little or no change. Also, DS2 may cause false positive readings when using M8 or M9 paper, or the M256 Detector Kit to check completeness of decontamination.

(c) Group III will consist of unpackaged or poorly packaged items which have been exposed to an agent in either vapor or liquid form. Foodstuffs in this group should be decontaminated only when absolutely necessary. The decision to use foods that have been contaminated is to be made by the commander. Decontamination procedure to be followed, in order, is: trim surface fat and grossly contaminated areas; wash with water or 2-percent sodium bicarbonate solution; then boil in water.

1. Boiling in water may be eliminated when the contamination has been only with the vapors of irritant agents. When such an exposure has been light, aeration for a short time may be used for decontamination.

2. Frying, roasting, or broiling will not remove traces of blister agents from meats. In general, salvage of foods heavily contaminated with droplets of the blister agents, especially the arsenical blister agents, is not practical. Foods of high water or fat content are unfit for consumption and reclamation is not practical when contaminated with liquid mustard or a liquid nitrogen mustard.

3. When foods have been exposed to blister agent vapor, they can be reclaimed by washing with sodium bicarbonate solutions and rinsing with clear water, by intensive cooking, or in the case of dry provisions, by 24 to 48 hours of aeration. Lean meat contaminated with mustard vapor can be reclaimed by boiling in water for 30 minutes or more. With nitrogen mustard vapor contamination, the meat should be boiled in a 2-percent sodium bicarbonate solution. Discard the water used to boil the meat.

4. Nerve agent contamination is treated the same as blister agent contamination.

5. Foods, such as potatoes and hard-skinned fruits and vegetables, can be decontaminated by washing or scrubbing, followed by peeling or scraping, then washing again.

6. Prepared food in open containers will be contaminated; it must be temporarily isolated, or disposed of (bury or as directed by commander).

[J-22]

7. A food Item that is contaminated with irritants can be decontaminated by airing. Consumability is determined by taste rather than toxicity.

8. Phosgene is rapidly hydrolyzed, therefore, washing the food with water or airing it will usually suffice.

9. Food contaminated with white phosphorous should be destroyed.

10. Normally, hydrocyanic acid will have little effect on food supplies. The exposures will most likely be as a vapor. However, foods with a high water content may become unfit for consumption after exposure to high concentrations.

11. The effect of CK on foods is not known. Foods exposed to CK vapors are considered toxic.

12. Table J-8 lists the decontamination procedures for unpackaged food contaminated with a chemical agent.

(9) Decontaminating cattle, poultry, and other livestock is only attempted when other sources of food are not available. Heavily contaminated animals should be destroyed. Livestock contaminated lightly by phosgene, nerve agents, mustards, and arsenicals (such as vapor or liquid) may be slaughtered in the early stages of poisoning before the full effects of exposure are shown. If these animals are slaughtered in the preliminary stages of poisoning and all tissues exposed to the agent (the head, blood, lungs, organs, and local areas) are discarded, there is no danger in consumption of the meat, provided the animal passes a pre-slaughter and slaughter inspection. This is true even of animals poisoned by arsenical agents since the edible tissue will contain amounts of arsenic too small to be toxic. Organs (liver, brain, heart, kidney, and lungs) will contain more arsenic than the musculature and are discarded. The meat must be well cooked. Personnel involved in slaughtering procedures must be careful to prevent spreading contamination to the meat and to themselves.

(10) Decontaminating forage and grain exposed to only chemical agent vapors is by aeration. Aerated supplies, especially if mixed with larger amounts of uncontaminated supplies, produces no ill effects when fed to animals. Forage or grain heavily contaminated by liquid vesicants, especially arsenicals, should not be used.

Biological Warfare Agent Field Confirmation Identification Identification of a suspect biological warfare agent by means of devices/materials/technologies that are based on detecting biological markers using two or more independent biomarker results. Examples might include the findings of the presumptive biomarker identification with the addition of a positive PCR, ELISA, or electrochemiluminescence (ECL) results, using specific target nucleic acid sequences for the organism and antibody recognition of agent-specific antigen sites, respectively. (Field sample/specimen identification by forward deployed or forward positioned laboratories [such as the US Air Force Biological Augmentation Team (BAT), theater army medical laboratory, or forward deployed preventive medicine unit (US Navy) and homeland security Laboratory Response Network (LRN) Level B or C, US Army Community Hospitals or Medical Centers].)
Biological Warfare Agent Definitive Identification And Confirmation The specific identification of a suspect biological agent as to genus and species, serological type, or toxin. This level of identification is by means of devices/materials/technologies that are based on two or more independent biomarker results and using different methodologies. This level of identification is performed in a reference laboratory with a broader variety of methodologies available and highly skilled testing personnel, thus providing the highest levels of accuracy. (Sample/specimen identification is accomplished by homeland security LRN Level C and D and nationally recognized laboratory such as the US Army Medical Research Institute of Infectious Disease or Centers for Disease Control and Prevention.)
Biological Marker Characteristics of a biological agent (organism, virus, toxin, or product) that are specific to the agent. This includes (1) recognition of specific nucleic add sequences (DNA or ribonucleic acid [RNA]) unique to the bacteria or virus by a technique such as PCR; (2) identification of specific ECL assay; (3) specific growth properties as seen on selective media such as characteristic colony morphology on culture along with phage inhibition; (4) Identification using specific microscopic characteristics such as Gram stain, fluorescent antibody stain, immunohistochemical stain, or cytopathic effects.
Biological Warfare Agent Presumptive Identification Identification of a suspect biological warfare agent by means of devices/materials/technologies that are based detecting biological markers (biomarkers) using a single methodology. The biomarkers and/or methodologies used at this level of testing have significant limits to their accuracy. Agent identification to species level, or differentiation among a family of similar agents, may not be possible. This is equivalent to the LRN Level A and the US Army BIDS. (EXAMPLES: Identification by sensor triggering, hand-held devices [hand-held assays] or initial systems, or laboratory analysis employing one screening methodology [such as microscopic morphology, antibody/protein, or nucleic acid-based test].)

Patient Decontamination —The removal and/or the neutralization of hazardous levels of nuclear, biological, and chemical contamination from patients at a medical treatment facility. Patient decontamination is performed under the supervision of medical personnel to prevent further injury to the patient and [GL-11]to maintain the patient's health status during the decontamination process. Patient decontamination serves multiple purposes; it protects the patient from further injury, it prevents exposing medical personnel to the contamination, and it prevents contamination of the medical treatment facility.

1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

Section 2. Information about the Mission of Project Gutenberg™
Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.
Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation
Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.
The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.
While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.
International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.
Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.
Section 5. General Information About Project Gutenberg™ electronic works
Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.
Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.
Most people start at our website which has the main PG search facility: www.gutenberg.org.
This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
