In hazmat zones, which zone corresponds to the Hot Zone?

• A. IDLH
• B. Decontamination
• C. Hot zone
• D. Staging

Answer: (D)

Hazmat zone structure is about containing exposure by regioning the scene. The Hot Zone is the area where the hazardous material is present or is most likely to be present—the most contaminated space closest to the release. Access is restricted and only personnel in proper PPE performing the needed tasks may enter. The Warm Zone surrounds the Hot Zone and serves as the decontamination area and buffer for removing contaminants and donning/doffing gear. The Cold Zone is outside, where command and support activities occur in a safe environment. Staging is a separate area for gathering resources before deployment, not a hazmat zone. So, the zone that corresponds to the Hot Zone is the Hot Zone itself.
