Which zone in hazmat incident management is a transition area that supports decontamination and staging?

• A. Hot zone
• B. Warm zone
• C. Cold zone
• D. Exclusion zone

Answer: (B)

In hazmat incident management, zones are arranged to keep contamination contained while still allowing support operations. The warm zone sits between the contaminated hot zone and the clean cold zone. Its purpose is to act as a buffer where decontamination processes occur and where personnel, equipment, and patients can be staged before moving into the cold zone. This transition area prevents contaminants from spreading into the clean area and ensures that everyone and everything entering the cold zone is decontaminated and properly organized. So, the warm zone is the space that specifically supports decontamination and staging.
