<strong>Guidelines</strong> for Military Mass Casualty Decontamination Operations<br />

During a Domestic HAZMAT/Weapon of Mass Destruction Incident<br />

completed decontamination and are seeking medical care. Every effort should be<br />

made to ensure that health care professionals and officials are intimately involved<br />

with and part of <strong>MCD</strong> planning, training and operations. In addition, an <strong>MCD</strong><br />

approach that only considers decontamination from the incident site alone will not be<br />

effective in the face of casualties self-presenting to health care facilities rapidly and<br />

in high numbers.<br />

The principles of decontamination should guide all processes and priorities when<br />

planning and performing decontamination. 15 Table 5 compares the fundamentals<br />

and priorities listed in Field Manual 3-11.5 for military operations to those listed in<br />

the DHS TCL/UTL and USACBRNS/ECBC guidelines for civilian operations. 1,11,15<br />

Note that the three lists complement each other. The DHS’ TCL/UTL and<br />

USACBRNS/ECBC recommendations are more operational. The FM 3-11.5<br />

recommendations are more academic. Table 6consolidates these basic principles<br />

and associates them to specific USACBRNS collective tasks.<br />

1. Speed. Personnel should<br />

conduct decontamination<br />

operations as quickly as<br />

possible. Direct exposure to<br />

CBRN agents or toxic industrial<br />

materials will create casualties<br />

and could be fatal within<br />

minutes. The sooner equipment<br />

is decontaminated, the less likely<br />

it is to absorb the agent or<br />

spread to other surfaces.<br />

2. Need. Decontaminate only what<br />

is necessary. Personnel have a<br />

limited amount of resources<br />

available and should expend<br />

resources only where they are<br />

needed.<br />

3. Priority. Decontaminate the<br />

most essential items first;<br />

foremost will be the skin if<br />

contact occurs. Once wearing<br />

protective equipment, personnel<br />

should begin decontamination<br />

operations on clothing,<br />

equipment, and vehicles.<br />

4. Limited Area. Personnel should<br />

perform decontamination near<br />

the area where the<br />

contamination occurs. This limits<br />

the spread of contamination to<br />

other areas and reduces the<br />

time spent traveling.<br />

1. Test and identify all likely<br />

hazardous substances onsite.<br />

2. Establish decontamination<br />

site for victims.<br />

3. Implement emergency<br />

decontamination operations.<br />

4. Screen affected persons.<br />

5. Decontaminate victims<br />

exposed to CBRNE materials.<br />

6. Implement plans, procedures,<br />

and protocols to ensure on-site<br />

individual gross<br />

decontamination of persons<br />

and household pets affected by<br />

the incident.<br />

7. Readily identify people who<br />

have received gross<br />

decontamination.<br />

8. Implement technical<br />

decontamination for injured,<br />

contaminated victims.<br />

9. Monitor exit points for<br />

contaminant movement outside<br />

the isolation zone.<br />

10. Monitor clean areas within<br />

the contamination control line.<br />

1. Disrobing is the most critical<br />

step and removes up to 90% of<br />

physical contamination.<br />

2. Neither should disrobing nor set<br />

up of a high-volume, lowpressure<br />

water shower be<br />

delayed to introduce a soap<br />

water solution or to set up<br />

tents.<br />

3. Triage victims for<br />

decontamination before the<br />

water shower.<br />

4. Victims should be washed<br />

between 30 seconds and 3<br />

minutes.<br />

5. Decontamination of chemical<br />

vapors, biological material or<br />

radiological substances can be<br />

aided by rubbing hands or<br />

cleans cloths across the skin.<br />

6. Rubbing should start with the<br />

head and proceed down the<br />

body to the feet.<br />

7. Use victim observation areas to<br />

watch for delayed symptom<br />

onset.<br />

8. Perform additional secondary<br />

decontamination as<br />

necessary.<br />

* These <strong>Guidelines</strong> use the term “casualty” instead of “victim” or “patient.” However, cited references may use<br />

the terms “victim” and/or “patient.” These terms will not be changed to “casualty” when quotes are taken from<br />

the cited references.<br />
