In mass decontamination, which step is emphasized for rapid results?

• A. Removing clothing reduces 80% of contaminant
• B. Applying air freshener after decon
• C. Starting with high-pressure jets
• D. Delaying shower until evaluation completes

Answer: (A)

In mass decontamination, removing clothing is the fastest way to cut the contaminant load on a person. Contaminants are largely carried on fabrics, so taking clothes off can eliminate the majority of the contaminant right away, dramatically reducing the body burden and the risk of secondary spread or skin absorption. Because this step is quick and easy to perform, it allows many victims to begin decontamination immediately while more thorough washing continues.

Starting with high‑pressure jets can spread contamination and may not remove most of the contaminant quickly, and delaying the shower until after evaluation wastes valuable time. Applying air freshener doesn’t remove contamination, so it isn’t helpful for rapid decon, and delaying shower keeps contaminants on the skin longer.
