When personnel, equipment, and areas within the BSA have been exposed to NBC contamination, decontamination measures must be taken. With chemical agents, steps must be taken immediately. Deliberate decontamination is rare and limited to vital areas. Most items can be decontaminated with soap and water or decontaminating apparatus. The same applies to contamination with a biological toxin.
Radiological decontamination is accomplished by aging, sealing, or removal.
Company commanders are required to list in unit SOPs the priorities within their units. The FSB has no organic assets to perform deliberate decontamination. If it is required, support may be provided by a decontamination platoon of the chemical company supporting the brigade, though priorities are set by the brigade commander. He also directs and monitors the operations to ensure priorities are being followed. Decontamination procedures are outlined in FM 3-5 .
