Both the detailed troop and detailed equipment decontamination sites must be carefully shut down to
avoid danger from contamination hazards. The equipment used in decontamination operations will
become contaminated and normally will be decontaminated at the completion of the operation.
(Complete instructions for these procedures are listed in FM 3-5.) For the decontamination operations
planner, however, there are two important things to remember:
■ The equipment decontamination site must be closed down before the troop decontamination
site. This allows the troops working the vehicle site to process through the troop site.
■ The crews that shut down these sites should be well-rested, decontaminated soldiers, not
personnel coming off the decon line or other heavy detail. Since this too, is a heavy detail,
well-rested troops are more likely to pay strict attention to proper cleanup to prevent the
spread of contamination or inadequate marking of contaminated areas.
b. Marking and Reporting.
The chemical platoon will mark the site with standard NBC warning markers and report the
contaminated area through command channels using the NBC Warning and Reporting System.
The reconstitution phase is designed to return a decontaminated unit into a fully outfitted ready-to-fight
organization. After processing through decontamination, the unit moves to an assembly area for
reconstitution. The parent battalion assists the reconstituting unit.
a. Use of the BSA.
A slice of the Battalion Support Area (BSA) is integrated into thorough decontamination operations.
The slice, consisting of medical, supply, and maintenance elements, constitutes a one-stop refit that
allows units to leave the decontamination site fully prepared to fight. Companies are decontaminated
and reconstituted in the BSA. Battalions and larger elements are decontaminated and reconstituted in
the division or corps support area.
