In incident operations, where should backup personnel be positioned?

• A. Cold
• B. Hot
• C. Emergency
• D. Warm

Answer: (A)

Backup personnel are kept in the cold zone. This is the clean, uncontaminated area where responders can monitor the scene, rest if needed, and be ready to relieve others without exposure to the hazard. The hot zone is where the hazard is present, and only specially trained individuals with proper PPE operate there. The warm zone is a decontamination/transition area, where exposure risk is still present and not the location for standby teams. From the cold zone, coordinating with the incident commander and staging resources can happen safely, ensuring a quick, controlled response if additional support is required.
