Which statement best defines gross decontamination?

• A. Removes majority of contaminants quickly to reduce exposure risk
• B. Thoroughly removes residual contamination using specialized methods
• C. Is performed only in the cold zone
• D. Is the same as medical treatment

Answer: (A)

Gross decontamination means the rapid removal of the majority of contaminants to quickly reduce exposure risk. The emphasis is on speed and broad cleanup at the incident scene, usually in the warm zone, so people and responders aren’t carrying large amounts of contaminant as they move through the operation or toward medical care. This immediate step lowers exposure quickly, while more thorough decontamination—which uses specialized methods to remove residual contamination—comes later in a separate process. It isn’t medical treatment, and it isn’t limited to the cold zone; it’s specifically about quickly lowering contamination levels to protect people and responders.
