(3) While remaining in MOPP 4, crews prepare their vehicles for decon processing. Use the
on-board pioneer equipment to clean off mud and debris, then replace this equipment so it can be
decontaminated along with the vehicle. Remove seat covers and canvas items, as they can readily
absorb contamination and pose a transfer hazard.
Anything that cannot be decontaminated by standard means should be removed from the vehicle. Use
nonstandard decontaminants and methods to decontaminate these items. It is important that unit SOPs
designate which items may and may not be carried on vehicle exteriors so that special handling and
decontamination efforts can be kept to a minimum. Unit chemical personnel provide advice about how
(4) Move the vehicles to the detailed equipment decontamination site. Send dismounted
crews to the detailed troop decontamination site.
The contaminated unit provides the guides that control vehicle traffic through the detailed equipment
decontamination site. The layout of the site will determine the actual number of guides that are needed.
The company's key personnel must assist in traffic control.
Drivers move their contaminated vehicles through the equipment decontamination site. When halfway
through the process, a decontaminated assistant driver takes over for the contaminated driver, who then
proceeds directly to the troop decontamination area. You must plan your schedule for troop
decontamination so that these assistant drivers have completed the decon process and are available for
For planning purposes, assume: The first pair through in 50 minutes and a second pair takes 10 minutes.
This equals 2 pairs the first 60 minutes. After the first pair, twelve soldiers per hour can be
decontaminated. The first vehicle is finished in 90 minutes and the next vehicle takes 10 minutes. This
is two vehicles the first 100 minutes. After the first vehicle, six per hour can be decontaminated.
Site Clearance Phase.
Significant contamination will remain at the decon site following thorough decontamination operations.
Friendly units entering and/or operating in these areas could be endangered by this contamination.
Planners must ensure the contamination is kept inside the site and the area is clearly marked.
