Which zone contains personnel who are prepared to advance into the hot zone?

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

Answer: (A)

The warm zone is the area where personnel prepare to enter the hazardous area. It sits between the safe, exterior cold zone and the active hot zone, serving as the staging and preparation area where firefighters don and check PPE and SCBA, confirm assignments, and ensure equipment is ready before entry. This zone is managed to control safety and accountability as teams move into the danger area under incident command. The hot zone contains the actual hazards, while the cold zone houses command, rehab, and support operations.
