At a TRI, in which control zone does decontamination, if applicable, take place?

• A. The hot zone
• B. The cold zone
• C. The warm zone
• D. The red zone

Answer: (C)

Understanding how HazMat incident zones are arranged and where decontamination happens is key. Decontamination occurs in the warm zone, the transition area between the contaminated hot zone and the clean cold zone. This setup gives responders a controlled space to remove or reduce contamination from people and equipment before they move into the clean area. In the warm zone, you’ll perform decon procedures such as rinsing and doffing PPE in a way that prevents spread of contaminants. The hot zone is where the hazard is most concentrated and entry tasks occur under protection, while the cold zone is kept clean for nonhazardous operations. If decontamination isn’t needed, that’s fine, but when it is, the warm zone is the designated place for it.
