Which statement best describes the decontamination officer's primary responsibility in hazmat operations?

• A. Supervises all operations within the cold zone
• B. Oversees entry operations at the incident
• C. Supervises all decontamination activities in the warm zone
• D. Coordinates communications with outside agencies

Answer: (C)

Decontamination control is the primary duty in hazmat operations. The decontamination officer is responsible for supervising all decontamination activities that occur in the warm zone, ensuring the decon process is correctly implemented for people and equipment moving from the hot zone toward the clean area. This role involves setting up and managing the decon line, overseeing gross and fine decontamination, ensuring proper PPE doffing procedures, and containing wash water to prevent recontamination. The warm zone serves as the buffer between the contaminated hot zone and the clean cold zone, so the officer’s oversight keeps the flow of personnel and equipment safe and properly decontaminated before they proceed. While the incident commander coordinates the overall response and entry operations are carried out by entry teams, and communications with outside agencies are handled within the incident command structure, the decontamination officer’s focus is specifically on the decon process in the warm zone.
