Which of the following describes the warm zone?

• A. The warm zone houses decon and support functions.
• B. The warm zone is the command center.
• C. The warm zone is the clean area for PPE donning only.
• D. The warm zone is the public safety zone.

Answer: (A)

The warm zone acts as the decontamination area and support hub between the heavily contaminated hot zone and the clean cold zone. It’s where responders and equipment are decontaminated so contaminants don’t carry into the safe areas, and where essential support functions—like staging, medical monitoring, communications, and logistics—take place to keep operations running safely.

That’s why this choice fits best: it explicitly describes the warm zone as the place for decon and support functions. The command center is typically located in the cold zone to stay protected from contamination. Donning PPE is usually done in the cold zone before entering the hot zone, while the warm zone focuses on decontamination and doffing. The public safety zone refers to the outer perimeter used to protect bystanders, not the warm zone.
