Mass decontaminations would typically be used at:

• A. A terrorist event dealing with chemical/biological agents
• B. A traffic collision
• C. A house fire
• D. A flood response

Answer: (A)

Mass decontamination is the rapid removal of contaminants from large numbers of people who may have been exposed to hazardous substances. This approach is essential when an incident could contaminate many individuals at once, such as a terrorist event involving chemical or biological agents. It helps reduce exposure to others, protect responders, and prevent the spread of contaminants to medical facilities and the environment. In contrast, a traffic collision, a house fire, or a flood response centers on rescue, stabilization, and dealing with immediate hazards, and while decontamination might occur later if a chemical risk is identified, it does not typically require the rapid, large‑scale decon that a chemical/biological attack would.
