In zone management, which statement correctly describes the cold zone?

• A. Cold zone is the clean area used for support and final decontamination
• B. Cold zone is the contaminated area
• C. Cold zone is the transition/decon area
• D. Cold zone is the evacuation staging area

Answer: (A)

In zone management, the clean, non-contaminated area is set apart for support functions and final decontamination as personnel and equipment exit the contaminated zones. This zone hosts things like the incident command, communications, medical triage and treatment, staging, and the final step where any remaining contamination is removed before people re-enter safe areas. That combination of being clean and serving support plus the final decon step is what defines the cold zone. So the statement that the cold zone is the clean area used for support and final decontamination best matches how these zones are organized. The contaminated area is the hot zone, the transition/decon area is the warm zone, and while evacuation staging can occur there, its defining feature is the clean, supportive role and final decon procedures.
