Where is the command post located?

• A. Hot zone
• B. Warm zone
• C. Cold zone
• D. Green zone

Answer: (C)

The command post is kept in a clean, uncontaminated area so incident command can operate safely and effectively. In HazMat incident zones, the hot zone is where the hazard is present and entry is highly restricted; the warm zone serves as the decontamination and transition area; and the cold zone lies beyond the decontamination boundary, remaining free of contamination. This clean space is where the command post and support functions run, ensuring leaders have reliable communications, access to resources, and can supervise operations without exposure to hazards. The green zone isn’t the designated command post area in this framework, as it isn’t the clearly controlled, contamination-free zone used for leadership and coordination.
