Define hot zone, warm zone, and cold zone and describe the typical function of personnel in each.

Define hot zone, warm zone, and cold zone and describe the typical function of personnel in each.

• A. Hot zone is the clean area for command, warm zone houses decon, cold zone is contaminated.
• B. Hot zone is the contaminated area where entry teams work; warm zone houses decon and staging; cold zone is the clean area for command, support, and rehab.
• C. Hot zone houses decon; warm zone is for command posts; cold zone is outside the perimeter.
• D. Hot zone is where PPE is stored; warm zone is where vehicles are staged; cold zone is outside.

Answer: (B)

The main idea here is how the scene is divided to manage contamination: hot zone, warm zone, and cold zone each serve a distinct, clean-to-contaminated progression. In the hot zone, responders work in the contaminated area wearing full protective gear to perform entry, stabilization, reconnaissance, and initial actions at the event source. The warm zone is the transitional area where decontamination takes place and where staging and support activities occur, so equipment and personnel move through this area after initial stabilization but before entering the clean zone. The cold zone is kept clean and serves as the base for command, noncontaminated support functions, and rehabilitation for personnel. This arrangement matches the described option because it places the hot zone as the contaminated work area for entry teams, the warm zone as the location for decon and staging, and the cold zone as the clean area for command, support, and rehab. Other configurations misplace decontamination or misidentify what each zone should contain, which undermines safety and incident control.
