Which option correctly defines the cold zone in US&R operations?

• A. Cold zone is staging vehicles, equipment, and command post
• B. Cold zone is where the rescue occurs
• C. Cold zone is for decon
• D. Cold zone is hospital triage area

Answer: (A)

In US&R operations, the scene is divided by hazard and function, and the cold zone is the area outside the immediate danger where support operations are organized. It houses the base or command post and the staging area for vehicles and equipment, allowing leaders to coordinate, rest, and manage resources without exposure to hazards. This separation from the collapse zone keeps operations safe and efficient while the actual rescue happens in the hot zone and decontamination occurs in the warm zone.

The other activities described align with those other zones: rescuing people occurs where hazards are present, and decontamination happens in the warm zone to protect the cold zone from contamination. Hospital triage is typically conducted in a medical area associated with the incident but not the defining function of the cold zone.
