The zone where contamination has occurred or has the potential to occur, and requires established entry and exit control points is:

• A. Hot/exclusion zone
• B. Warm/contamination reduction zone
• C. Cold/support zone
• D. Safety/cold zone

Answer: (B)

In hazmat incident scenes, zones are set up to control contamination and protect responders. The zone between the highest-risk area and the clean area is the warm zone, also called the contamination reduction zone. This buffer is where contamination may be present and where decontamination happens, so you can move personnel and equipment safely toward the cold (clean) zone. Establishing controlled entry and exit points here prevents contaminants from slipping into the clean area and ensures that only properly decontaminated individuals and gear proceed onward. That’s why this option—the warm/contamination reduction zone—is the best fit. The hot/exclusion zone is the actual contaminated area itself, the cold/support zone is the clean area, and the safety/cold zone isn’t a standard designation.
