What is the purpose of an Isolation Zone?

• A. To control access to the incident scene.
• B. An area established to protect responders and others from exposure.
• C. To determine the weather conditions.
• D. To decontaminate personnel only.

Answer: (B)

The Isolation Zone is a protective buffer that prevents exposure by keeping access controlled and separating the high-hazard area from areas used for decontamination and support. Its main purpose is to protect responders and others from coming into contact with hazardous materials, reducing the risk of spread and cross-contamination as operations proceed. This zone sits between the most dangerous zone and the safer zones, enabling safe entry/exit and organized handling of the incident. Weather conditions are not determined there, and decontamination happens in the decontamination areas, not strictly within the isolation zone.
