What does the Decontamination procedure in incident response involve?

• A. Procedures to remove hazardous substances from people, equipment, and the environment while protecting responders and victims.
• B. A routine cleaning of facility surfaces only after an incident.
• C. Disposal of all waste without safety measures.
• D. Immediate evacuation with no decontamination.

Answer: (A)

Decontamination in incident response means removing or neutralizing hazardous substances so they don’t harm people, spread to others, or contaminate equipment and the environment. It covers people, gear, and the scene, and it includes steps to protect everyone involved, from responders to victims, during the cleanup. The aim is to reduce the contaminant on exposed individuals, on equipment, and in the surroundings so it’s safe to re-enter the area and so no secondary exposure occurs. In practice, this can involve different levels of cleaning for people and gear, proper handling of contaminated waste, and using appropriate protective measures to prevent cross-contamination.

This description best captures the purpose of decontamination. Routine cleaning by itself doesn’t address removing hazardous substances from people or ensuring safety for responders, and disposal without safety measures ignores the need to control exposure. Immediate evacuation with no decontamination omits the essential step of removing contaminants to prevent harm.
