The commander is responsible for designating MOPP level. All soldiers must know the signals and alarms and react to them quickly. Detection personnel should be designated in advance to survey contaminated areas. 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.
