PREPARATION- The materials and equipment needed at this station are as follows:

. Cutting tool . Two 30-gallon garbage cans . One hundred plastic bags (or at least one per Seabee)

. Ten boxes M258A1 or M291 decon kits

This station requires only one decon member. He or she supervises the actions of the troops processing through the station.

EXECUTION- Buddy teams will divide and continue the decontamination process individually. The station attendant assists in the removal of the smock and trouser by cutting them off.

CAUTION Ensure that contaminated trousers and smock do not fold the clean uniform. parts of the in and touch The station attendant cautions the troops not to rub the contaminated boot against his or her clean leg and to step wide enough so as not to rub the clean leg against the overgarment. If this step is done improperly, the agent may be transferred to the underclothing or skin.

Station 4- Overboots and Gloves Removal

This step removes contaminated overboots (footwear covers) and gloves to limit the spread of contamination. Overboots and gloves are also decontaminated for reissue.

PREPARATION- The following equipment and materials are needed:

Tape Cutting tool Eight 30-gallon containers (garbage cans) One hundred plastic bags (or one per Seabee) Two scrub brushes Two ponchos or large plastic sheets CAM M8 paper 10 percent STB/ HTH solution Hot, soapy water Cold rinse water The station will be setup as shown in figure 6-7. Fill two 30-gallon containers with hot, soapy water and two containers with 10 percent STB/ HTH solution. Place the two scrub brushes near the containers. Fill two 30-gallon containers with cold rinse water.

Two decon team members are needed to decontaminate the overboots and gloves. One person processes the overboots, while the other person processes the gloves.

Use the tape to mark the liquid contamination control line (LCL) on the ground clearly. The LCL separates the "dirty" from the "clean" areas. Place the cutting tool, two containers, and the plastic bags on the "dirty" side of the liquid contamination control line.

NOTE: An exception to the clean area is the contaminated gloves. However, you must ensure no liquid agent is spilled on the ground beyond the liquid contamination line.

EXECUTION- The attendant unfastens or cuts the strings or elastic closures on the boots. The station attendant holds the boot while the Seabee steps out and across the control line. The action is repeated for the other boot. Boots are then discarded in the designated container by the station attendant. If the boot cannot be removed by this process, the attendant cuts off the boot. The Seabee works the chemical protective gloves loose using the pinch-pull method, and the station attendant pulls the gloves off. The station attendant discards the gloves in a container on the "dirty" side of the control line. Station 4 attendant does his or her duty from the dirty side of the liquid contamination control line.

The boots and gloves are decontaminated in the following process:

Step 1. Submerge the gloves and boots into the container of hot, soapy water. Some contamination will be removed during this step. When the boots and gloves are removed from the container, ensure that no water remains inside the boots and gloves. Do not decon any item that is unserviceable.

Step 2. Submerge the boots and gloves into the container of HTH solution. Thoroughly scrub the items until no visible contamination remains. After scrubbing, submerge each item again before moving them into the rinse container.

Step 3. Thoroughly rinse the scrubbed items, making sure that the items are rinsed inside as well as outside. Check all the gloves and boots for holes, tears, or punctures and discard any that are found.

Step 4. Dry the usable items. Discard any glove or boot having punctures, tears, rips, holes, or other damage into a pile. Place the usable items on the poncho or plastic sheet to air-dry and weather.

Step 5. Place the items into the plastic trash bags, along with an M256 detector ticket. If the detector ticket shows no contamination, the items can be reissued or stored for issue later. If the detector ticket shows contamination remaining, the station attendants can recycle the items or discard them.

Obviously, you cannot check for the agent on the combat boots if you do not remove the overboots. If the overboots are not properly removed, you risk contaminating your combat boots and spreading contamination to clean areas. If rubber gloves are not properly removed, you risk contaminating your skin and underclothing at this and the following stations.

Station 5- Monitor Performing this step identifies contamination on personnel, provides spot decon capability, and provides medical aid, as required.

PREPARATION- The following materials and equipment are needed:

First-aid supplies CAM Five packs M8 detector paper per 100 people One case M258A1 or M291 skin decontamina-ting kits per person

Two troops are needed to operate this station. A corpsmen should be present to treat any personnel suffering from chemical agents symptoms.

EXECUTION- The monitor checks the individuals for contamination. Corpsmen will administer first aid as required. Liquid agent can be detected with the M8 detector paper. Small quantities of agent vapor can be detected with the CAM. Symptoms of agent poisoning are the most obvious indication of skin contamination. At this step, the medic checks each troop for symptoms and treats them as required. Troops should report any damage to their MOPP gear that was identified at stations 2, 3, and 4. Any areas identified as contaminated can be decontaminated with the M258A1 or M291 decontaminating kit by the station attendants. Individuals will be monitored after decon. It is possible that all liquid chemical contamination is absorbed into the clothing. Chemical detector paper (M8 and M9) will indicate negative, even though there is a hazard. The COC can choose to conduct more extensive contamination checks here if time is available. This will decrease the risk of casualties.

Station 6- Mask Removal Performing this step removes the mask without contaminating the Seabee. The mask is taken to a mask decon point, limiting agent transfer at the site.

PREPARATION- The following equipment is needed:

. M8A1 automatic chemical agent alarm

Two troops are needed to operate this station. They remove and carry masks to the mask decon point (station 7).

EXECUTION- If the hood is still attached to the mask, the attendant pulls the hood over the front of the mask, grabs the mask by the voicemitter cover, and pulls the mask off the individual. The individual holds his or her breath as the mask is removed. If the mask has optical inserts, the attendant holds the mask open so the individual can remove the inserts without touching the outside of the mask. The individual then walks upwind 5 meters, crosses the vapor contamination control line, and resumes breathing. The station attendant brings the mask to station 7, mask decon point.

No chemical vapor hazard is expected beyond the vapor hazard contamination control line if the wind direction remains constant. Position the M8A1 or the M-21 automatic chemical agent alarm upwind of the site to warn of vapor hazards.

Station 7- Mask Decon Point Performing this step removes all the contamination from the mask.

PREPARATION- The following material and equipment are needed:

Four containers (about 3-gallon capacity) CAM (for chemical only) Hot, soapy water Rinse water Mask sanitizing solution Immersion heater 30-gallon container Two sponges One case of paper towels

Dig a sump (4 feet wide by 4 feet long by 4 feet deep) in which to discard used filters and canisters.

Three troops are needed to operate this station. Two troops will strip, wash, rinse, sanitize, and dry masks. The other troop checks the masks and carries them to the reissue point.

EXECUTION- Remove the eye lens, the outserts, and the hood, if the hood was not cut off at station 2. Remove and discard the filters or canisters. Put the items into the properly marked containers. Wash the mask, the hood, and the outserts in hot, soapy water. Rinse them in clean water, dip into sanitizing solution, agitate for 5 minutes, then rinse in clean water again. Add one tube of mask sanitizing solution (calcium hypochlorite) to each quart of water. Wipe with rags until they are almost dry. Discard each gallon of mask sanitizing solution into a sump after ten masks. The attendant checks for contamination with a CAM. If the mask is still contaminated the attendant recycles it for more decon and then decontaminates his or her rubber gloves. If the mask is not contaminated, the attendant takes the unassembled mask to the reissue point. The attendant must take care not to contaminate the reissue point or themselves.

Not properly performing this step will cause the risk of contaminating troops when reissuing masks at the reissue point. Even though the step is done correctly, there is still a possible danger when many masks are stacked together. Small amounts of residual vapor from each mask can become potentially dangerous.

Station 8- Reissue Point Performing this step will ensure that you receive all of your individual gear and your protective mask with all the components.

PREPARATION- You will need the protective mask PLL parts. The unit supply company and chemical POIC set up the reissue point to provide the troops with replacement parts and assist in mask maintenance.

EXECUTION- Reissue the mask with the components to the troops who assembles the mask in the assembly area. Individuals pick up individual gear and move it to postdecon assembly area.
