What is the first step in gross decontamination at the scene?

• A. Gross decon at scene to remove bulk contamination
• B. Remove outer clothing
• C. Thorough rinse
• D. Secondary/technical decon

Answer: (A)

The first step is to rapidly cut the contaminant load at the scene. Gross decontamination is all about quickly removing the bulk of the contaminant from a person or equipment right where the exposure happened, before any more detailed cleaning. This early, broad cleanup reduces the amount of poison or hazardous material that can spread to responders and other victims, and it makes the subsequent, more thorough decon steps safer and more effective. In practice, this means initiating the gross decon process at the scene to strip away as much contamination as possible in the quickest way, often through removal of contaminated material and initial washing. After this rapid reduction, a thorough rinse can address what remains, and secondary/technical decon can be used for stubborn residues in a controlled environment. Removing outer clothing is part of reducing contamination, but the defining first action in the gross decon sequence is to start the gross decon process itself to remove bulk contamination quickly.
