What is the purpose of the warm zone in incident management?

• A. The area of highest hazard where entry is restricted.
• B. The area used for decontamination and support functions.
• C. The area where incident command posts and communications are established.
• D. The area where responders wear SCBA and orient themselves before entering the hot zone.

Answer: (B)

The warm zone serves as the buffer between the contaminated hot zone and the clean cold zone, with its main job being decontamination and related support functions. In this area, responders and equipment go through decontamination procedures, doffing and cleaning of PPE as needed, and receive vital support such as medical monitoring, rehab, and staging of resources. Keeping this work in the warm zone prevents contamination from moving into the clean area and helps maintain overall scene safety. The incident command post and communications are typically established in the cold zone, while the hot zone remains the area of highest hazard. Orientation and donning of protective gear may occur in the warm zone as responders prepare to enter, but the primary purpose here is decontamination and support.
