031-503-1023 (SL2) - Protect Yourself from Nuclear, Biological, and Chemical Injury/Contamination When Changing Mission-Oriented Protective Posture Gear

Standards: Decontaminated individual gear and equipment without spreading contamination onto skin or undergarments. Set uncontaminated gear aside on an uncontaminated surface. Changed overgarments, overboots, and gloves without spreading contamination to the uncontaminated set of MOPP gear. Changed MOPP gear without yourself or your buddy becoming a casualty.

Conditions: You are in MOPP 4 with load-bearing equipment (LBE). Your MOPP gear is contaminated. Your buddy is in MOPP 4 with LBE, and he is available to assist you with MOPP gear exchange. You have an uncontaminated set of chemical MOPP gear for yourself and your buddy and a personal decontaminating kit. For chemical and biological (CB) decontamination, you have one personal decontamination kit per person; one 50-pound drum of super tropical bleach (STB) dry mix; and a piece of plastic, a poncho, or similar material. For radiological decontamination, you have 5 gallons of water (if water is not available for radiological decontamination, brush, wipe, or shake off contamination); three pails (3-gallon capacity); one can of government issue (GI) soap or liquid detergent; two sponges; paper towels; and a piece of plastic, a poncho, or similar material.

Standards: Decontaminated individual gear and equipment without spreading contamination onto skin or undergarments. Set uncontaminated gear aside on an uncontaminated surface. Changed overgarments, overboots, and gloves without spreading contamination to the uncontaminated set of MOPP gear. Changed MOPP gear without yourself or your buddy becoming a casualty.

Performance Steps

Note. Both soldiers perform steps 1 and 2 at the same time.

Note. If the environment is only CB contaminated, omit steps 2 and 4. If the environment is only radiologically contaminated, omit steps 1 and 3. If the environment is radiologically and CB contaminated, perform all steps.

1.   Decontaminate your individual gear for CB contamination without assistance.

Note.  If at any time during the technique you suspect you have spread contamination onto your skin or undergarments, decontaminate immediately with the personal decontaminating kit available; then proceed with the MOPP gear exchange.

a. Remove your chemical protective helmet cover, and discard it.

b. Cover your gear with STB dry mix.

c. Brush or rub STB dry mix into the material, and shake off any excess STB.

d. Set your gear aside on an uncontaminated surface (plastic, poncho, or similar material).

2.   Decontaminate your individual gear for radiological contamination, without assistance.

a. Brush, wipe, or shake off dust or radiological contamination from your individual gear.

b. Wash the equipment with warm, soapy water if available.

c. Set the equipment aside to dry on an uncontaminated surface (plastic, poncho, or similar material).

Note. Do not reverse roles until steps 3 through 8 are completed.

3.   Decontaminate your hood and mask for CB contamination.

a. Buddy # 1-

(1)  Loosens Buddy # 2's drawcord.

(2)  Removes Buddy # 2's under-arm straps from under his arms.

(3)  Moves Buddy # 2's straps over his shoulders.

(4)  Reattaches Buddy # 2's straps to the VelcroR and hook-and-pile patches on the bottom of his hood.

b. Buddy # 1 decontaminates Buddy # 2's hood and exposed parts of his mask using the M291 decontamination kit.

(1)  Buddy # 1 wipes Buddy # 2's mask eye lens outserts first.

(2)  Buddy # 1 wipes Buddy # 2's entire mask from the top of the hood down.

c. Buddy # 1 repeats steps 3b(1) and (2) on his own hood and mask using the M291 decontamination kit.

d. Buddy # 1 decontaminates his own gloves with the personal decontaminating kit after Buddy # 2's mask is decontaminated.

4.   Decontaminate your hood and mask for radiological contamination.

a. Buddy # 1 dips a sponge in hot, soapy water and wipes Buddy # 2's mask and hood (and the canister and hose of the M42-, M43-, or M40-series protective masks).

b. Buddy # 1 rinses Buddy # 2's hood and mask with a sponge dipped in clean water.

c. Buddy # 1 dries Buddy # 2's hood and mask with paper towels or a rag.

d. Buddy # 1 wipes down his gloves.

Note. Cool, soapy water is not as effective for removing contamination, but it can be used if you scrub longer. If no water is available, the personal decontaminating kit may be used for CB decontamination.

5.   Roll your hood.

Note.  Leave the zipper closed.

a. Buddy # 1 lifts Buddy # 2's hood straight up off his shoulders by grasping the straps.

b. Buddy # 1 pulls Buddy # 2's hood over his head until most of the back of his head is exposed (the hood should not be completely over Buddy # 2's face).

c. Buddy # 2 places his hand over the voice transmitter, if necessary, to prevent the mask seal from being broken.

d. Buddy # 1 rolls Buddy # 2's hood tightly, starting at the chin and working around the mask without pulling it completely off the back of his head.

Note.  Do not reverse roles. Go to the next step. Only Buddy # 2 will have his hood decontaminated and rolled at this time.
