The _____ zone is a restricted zone where rescue is taking place. Only personnel who are dealing directly with the treatment or freeing of victims are allowed.

• A. Hot
• B. Cold
• C. Warm
• D. Access

Answer: (A)

Zone designation during a rescue operation determines who may enter and what protection is required. The area where the hazard exists and where rescuers are actively working to locate and extricate victims is the hot zone. It is strictly restricted to personnel who are directly engaged in treatment or freeing of victims, with continuous monitoring, accountability, and full PPE due to risks like unstable structures, falling debris, or hazardous atmospheres. The hot zone is the focus of the rescue effort and where immediate victim contact and care occur.

The warm zone sits between the hot zone and the cold zone and serves as a buffer for decontamination, casualty processing, and staging. It allows for safe transition of personnel and equipment between the hazardous area and the safe area.

The cold zone is the safe, clean area where command, support, and external accountability operate, away from the hazards. Access control is important, but the term used for the area where rescue actions take place is the hot zone.
