Which zone is typically considered the area where entry is hazardous and high-level PPE is used?

• A. The hot zone
• B. The cold zone
• C. The support zone
• D. The outer scene

Answer: (A)

The area where entry is hazardous and the highest level of PPE is required is the hot zone. This is the most contaminated part of the scene, where responders may be exposed to the release, so protective gear is at its maximum (often including full chemical-protective suits and self-contained breathing apparatus). Work in the hot zone is tightly controlled and conducted by trained entry teams, with decontamination procedures set up at the zone boundary to prevent spread of contamination. The cold zone, farther away, is a safe area where decontamination ends and routine actions occur with less protective gear, while the warm zone serves as a buffer and decon/staging area between hot and cold.
