In offensive response planning, which zone is designated as the hot zone?

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

Answer: (D)

The hot zone is the area where the hazard is present and operations are conducted directly on or with that hazard. In offensive response planning, this boundary contains the greatest level of contamination, so only trained personnel wearing the highest level of protective equipment go in, and entry is tightly controlled to prevent the spread of contamination. This zone is where the mission drives risk, and it is kept as small and well monitored as possible to protect responders and the surrounding environment.

The other zones support safety and decontamination. The cold zone is the safe, non-contaminated area used for staging, command, and after-action activities. The warm zone lies between the hot and cold zones and serves as the decontamination corridor where personnel and equipment are decontaminated before moving out of the hot zone. The term “safe zone” isn’t part of the standard zone terminology, and it doesn’t designate the same defined boundary as the hot zone.
