In incident operations, which zone primarily houses personnel directly supporting rescuers and includes decontamination activities?

• A. Hot zone houses rescue operations
• B. Cold zone houses decontamination
• C. Recovery zone houses rest and rehab
• D. Warm zone houses personnel directly supporting rescuers and decon

Answer: (D)

The key idea is how incident zones separate the hazard from support and clean areas. The zone that houses personnel who directly support rescuers and handles decontamination is the warm zone. It serves as the buffer between the hot zone, where the hazard and rescue work occur, and the cold zone, which is kept clean. In the warm zone, responders perform decontamination, manage equipment, monitor health, and coordinate staging and support functions so rescuers can operate safely in the hot zone and then move toward the cold zone without carrying contaminants. The cold zone remains the clean area where incident command, planning, and rehab logistics typically occur. Keeping decontamination and support in the warm zone helps prevent cross-contamination and maintains an organized, safe flow for the operation.
