In zone-based CBRN management, which statement correctly identifies the cold zone?

• A. Cold zone is the clean area
• B. Hot zone is the contaminated area
• C. Warm zone is the contaminated area
• D. Evacuation zone is the contaminated area

Answer: (B)

In zone-based CBRN management, operations are organized into three zones based on contamination risk: hot zone (contaminated, restricted), warm zone (decontamination and transition), and cold zone (clean). The cold zone is the clean area where personnel can operate safely, manage communications, stage equipment, and perform non-contaminated tasks without the hazards present in the other zones. This separation prevents the spread of contamination and supports efficient incident handling. The statement that the cold zone is the clean area matches this structure. The hot zone is the contaminated area, which is not the cold zone; the warm zone serves as a transitional, decontamination area and is not the clean zone either. The term evacuation zone isn’t part of the standard zone labeling for this framework.
