What is decontamination efficacy in CBRN operations?

• A. The time required for decontaminants to work
• B. The extent to which contaminants are removed from surfaces or equipment
• C. The amount of decontamination supplies needed
• D. The speed of dissemination of information

Answer: (B)

Decontamination efficacy is about how well the cleanup removes or neutralizes contaminants from surfaces or equipment. It's a measure of success: after performing a decontamination procedure, how much contaminant remains compared to what was present initially? Practically, this is often expressed as a percent reduction or a reduction factor and is judged against safety or operational thresholds. A high efficacy means most of the contaminant has been removed or inactivated, lowering exposure risk and enabling safe continuation of tasks. Many factors influence efficacy, including the contaminant’s chemistry, how it adheres to the surface, the material and porosity of the surface, the decontaminant used, how it is applied, the contact time, temperature, and any mechanical action like scrubbing. This concept is about removal effectiveness, not how fast the decontaminant acts, how much supply is used, or how quickly information is disseminated.
