Which statement is correct regarding mass decontamination guidelines?

• A. A minimum of 3 engines are required to perform mass decontamination.
• B. A nozzle flowing at least 175 GPM is required.
• C. All victims must go through dry decontamination prior to wet decontamination.
• D. Each agency should adopt a Standard Operating Guideline for mass decontamination.

Answer: (D)

Standardization of mass decontamination through an agency-wide Standard Operating Guideline is essential because it provides a clear, repeatable process that coordinates roles, steps, equipment, water management, and incident command. This consistency supports fast, safe decontamination, protects responders, and enables effective training and drills across all responders and incidents. The other statements aren’t universally required: the number of engines is situational and not a fixed guideline; a specific nozzle flow rate isn’t mandated across all agencies; and requiring dry decontamination for every victim before wet decontamination isn’t a universal rule—many protocols prioritize rapid wet decon to remove contaminants quickly, with dry decon used selectively.
