Which control zone contains the command post?

• A. Hot zone
• B. Warm zone
• C. Cold zone
• D. Staging area

Answer: (C)

In incident response, the command post is set in the cold zone—the safe area well away from the hazard. This placement gives incident command the freedom to plan, communicate, and oversee operations without exposure to danger or the need for specialized PPE.

The hot zone is the immediate danger area where hazards are present, so placing the command post there would expose leaders and hinder quick, clear decision-making. The warm zone acts as a buffer and decontamination area near the hot zone; while it can host some support activities, it’s not the proper spot for the central command because it still carries contamination risk. The staging area is used to gather and hold resources awaiting deployment and is typically in the warm zone—not the primary command center.

Thus, the command post belongs in the cold zone.
