The Warm Zone is the area where decontamination and hot zone support take place.

• A. Decontamination and hot zone support take place
• B. A staging area
• C. The command post
• D. A containment area around the incident

Answer: (A)

The warm zone serves as the buffer between the contaminated hot zone and the clean cold zone, and its main purpose is to support decontamination and provide hot-zone assistance. This is where people and equipment pass through decontamination to reduce contamination before they move back into the cold zone, and where resources needed for the hot zone are staged and coordinated. That makes the statement true: decontamination and hot-zone support take place in the warm zone. A staging area is part of the warm zone but not its defining function, the command post is typically in the cold zone, and a containment area around the incident describes the hot zone rather than the warm zone.
