What is the area that surrounds the incident site and whose size is proportional to the hazards that exist

• A. Exclusion zone
• B. Hot zone
• C. Rescue area
• D. Warm zone

Answer: (C)

The concept being tested is how incident scenes are divided into zones based on hazard exposure. The area immediately around the hazard where dangers are present and access is strictly controlled is the hot zone. Its boundary is defined by how far the hazard can affect people or equipment, so the size naturally grows or shrinks with the level and spread of the danger. Inside this zone, only trained personnel wearing appropriate protective gear engage with the hazard.

This is different from a warmer buffer that sits between the hot zone and the outer areas; the warm zone is for decontamination, staging, and support. Farther out is the cold zone, where command, logistics, and nonhazardous activities occur. The term rescue area isn’t a standard way to describe a zone defined by hazard extent, so it doesn’t fit as well with the idea of a boundary sized to the hazard.
