What is the proper description of the cold zone on the fireground?

• A. The area closest to the fire for rapid attack.
• B. The area where decon occurs.
• C. The area used for live-fire training.
• D. Safe areas outside with operations support.

Answer: (D)

The cold zone is the safe area outside the hazard where support functions operate. It sits beyond the hot zone, keeping personnel away from heat, smoke, and life-threatening conditions, so incident officers, staging managers, rehab crews, and communications teams can work effectively without being exposed to the danger. This is why the cold zone is described as safe areas outside with operations support.

Decon is typically set up in the transition area between the hot and cold zones (often called the warm zone), rather than inside the cold zone. Live-fire training occurs in controlled training environments, not on an active fireground.
