The longer the gear is washed or left out in the air after
washing, the further the contamination level will be reduced. The amount of
chemical agent vapors desorbing out of the gear will be reduced. Gear may
be put in closed areas or plastic bags and checked for hazardous vapors with
The preceding paragraph outlines the minimum that should be done.
Depending on time available, more extensive washing and checking
procedures may be useful.
You may decide to wash equipment
longer or let it air outside after washing. This further reduces
the amount of agent vapors desorbing, or bleeding, out of pistol
belt, mask carrier, and helmet covers. Equipment can be put in
closed areas or plastic bags and checked for hazardous vapors
with CAM or M256-Series Chemical Agent Detector Kit.
If scrubbing and washing are not done properly, contamination may remain on
The resulting vapor hazard could cause casualties to unmasked
personnel, particularly in closed areas or heavily wooded areas where air
circulation is poor.
b. Station 2.
Overboot and Hood Decon.
Actions at this station neutralize gross contamination on overboots and
lower trouser legs. It removes gross contamination from hood and mask.
Prepare a shuffle pit by digging a shallow pit about three feet long by six
inches deep. Fill the shuffle pit with STB dry mix. Prepare the STB dry
mix by mixing three parts earth to two parts STB. Add more STB to the mix
after 10 soldiers have processed through the shuffle pit. The chemical unit
will provide 10 drums of STB to prepare the dry mix.
The following equipment/supplies are needed at this station:
One M258A1 or M291 Skin Decontaminating Kit per person
6 feet by 6 feet piece of plastic
Trash bags (as required)
Ten drums of STB
