Which zone is typically used for decontamination and support functions?

• A. Hot/exclusion zone
• B. Warm zone
• C. Cold zone
• D. Blue zone

Answer: (B)

Hazardous-material operations use a three-zone layout to keep contamination contained, with the warm zone serving as the transition area where decontamination and essential support functions occur. This zone is designed to be between the contaminated hot zone and the clean cold zone, so contaminants are removed before responders or equipment move into the non-contaminated area. In the warm zone you’ll find decontamination activities for personnel and gear, as well as support functions like staging, communications, medical rehab, and supply logistics. Keeping decontamination here prevents the spread of contamination into the cold zone and helps ensure that only properly decontaminated personnel and equipment enter the clean area. The hot zone is the contaminated work area with restricted access, and the cold zone is the clean area where incident command and non-contaminated operations take place.
