Which sequence correctly describes basic decon steps at a hazardous incident?

• A. Rinse, soap, gross decon
• B. Gross decon, soap and water wash, rinse
• C. Soap only
• D. Decon is unnecessary

Answer: (B)

Basic decontamination is a three-step process designed to rapidly reduce exposure and prevent spread of contaminants. Start with a gross decon to remove the majority of contamination at the scene; this quick action eliminates most of the contaminate so it won’t spread to responders or equipment. Next, do a soap and water wash. The soap helps loosen and emulsify residues that bulk rinsing can’t remove, further reducing contaminants on skin or gear. Finish with a rinse to flush away the remaining residues and soap, leaving a cleaner surface for any follow-up decon or handling.

If you used only soap, bulk contamination might remain. If you rinsed without washing, stubborn residues could stay attached. Saying decon isn’t necessary ignores a critical safety step for protecting people and the environment at hazardous incidents.
