When is it appropriate to decontaminate a bystander who was exposed to OC spray?

• A. Only after a medical evaluation confirms exposure.
• B. As soon as safely possible, after ensuring scene safety and while protecting yourself and others from cross-contamination.
• C. Never; bystanders do not require decontamination.
• D. After you finish your shift.

Answer: (B)

Decontaminating a bystander should happen as soon as it’s safe to approach and while you’re protecting yourself and others from cross-contamination. The goal is to remove the irritant quickly so the bystander isn’t exposed longer than necessary, which helps reduce ongoing irritation and symptoms. You prioritize scene safety first and take steps to limit spreading the spray—such as avoiding bringing contaminated gear or clothing into clean areas and using proper cleaning methods (water flush and removal of contaminated clothing) before anything else. Waiting for a medical evaluation before decontamination can prolong discomfort and exposure, and delaying decontamination after a shift wouldn’t protect the bystander or responders.
