Definition & Operational Usage
An isolation zone is a designated area surrounding a hazardous materials incident where the risk of contamination or exposure is highest. This zone is established to limit access to only those personnel who are properly equipped and trained, ensuring a controlled environment for operations. Not to be confused with the warm zone, which allows for some decontamination activities, the isolation zone is the most restricted area, often marked in accordance with Incident Command System (ICS) protocols.
