Back up personnel should be advised of the incident action plan and positioned in the zone.

• A. hot
• B. warm
• C. cold
• D. emergency

Answer: (C)

In hazardous materials responses, the scene is divided into zones by risk: hot is the contaminated area, warm is the decontamination corridor, and cold is the clean area where command, staging, and support stay. Back-up personnel aren’t performing the immediate hands-on tasks in the hot zone; they need to know the plan and be ready to support or take action as needed. Positioning them in the cold zone keeps them safe from exposure while ensuring they can receive the incident action plan and stay coordinated with the incident command. The warm zone is for decontamination and transitional activity, which still carries exposure risk, so it’s not the best place for briefing and long-term backing.
