What is the purpose of the Isolation Perimeter in HazMat incident management?

• A. Crowd Control, IC responsibility
• B. Decontamination operations
• C. Medical triage
• D. Environmental sampling

Answer: (A)

The outer boundary, the isolation perimeter, is about scene security and access control. It creates a safe buffer around the incident so the public and untrained personnel stay away, preventing exposure and giving the incident commander a controlled space to observe, coordinate, and direct operations. By restricting entry to authorized responders and equipment, it helps manage resources, maintain safety, and reduce interference. Decontamination, medical triage, and environmental sampling happen within inner zones designed for those tasks, not at the outer isolation boundary.
