The warm zone is also known as the Contamination Reduction Zone.

• A. Contamination Reduction Zone
• B. Warm Zone
• C. Hot Zone
• D. Decontamination Zone

Answer: (A)

Hazmat response uses zones to stop the spread of contamination. The warm zone sits between the hot zone, where the hazard is highest, and the cold zone, where the area is considered clean. Its main role is to reduce contamination as people and gear move toward safety, which is exactly what the term Contamination Reduction Zone communicates. In this zone you organize decontamination activities, manage contaminated PPE and equipment, and help transition responders from the danger area to the cleaner area without carrying contaminants forward. So the warm zone is effectively the Contamination Reduction Zone.
