Define a hot zone and a cold zone in rescue operations.

• A. Cold zone is contaminated area; hot zone is safe area for personnel
• B. Cold zone is a safe area for decontamination only
• C. Hot zone is a contaminated or dangerous area; cold zone is a safe area for personnel
• D. Cold zone is where PPE is stored; hot zone is for rest

Answer: (C)

In hazardous rescue operations, zones separate levels of risk to protect responders. The hot zone is the contaminated or dangerous area where the hazard exists and where entry is limited to trained personnel wearing the appropriate PPE to address the threat. The cold zone is the safe area where personnel can operate without exposure to the hazard, handle planning and logistics, stage equipment, provide medical support, and manage decontaminated gear after it’s been through proper decon steps. This separation helps prevent the spread of contamination and keeps rescuers working where they’re least at risk.

So the statement that best fits is that the hot zone is a contaminated or dangerous area, and the cold zone is a safe area for personnel. The other descriptions mix up where the danger lies, or limit the cold zone to a single function, which doesn’t reflect how zones are used to control exposure and support operations.
