Which statement describes a common initial action to secure a hazmat incident scene?

• A. Establish perimeter and access control; deploy ICS and assign roles including IC, Safety, and Liaison.
• B. Evacuate all personnel immediately.
• C. Collect samples without PPE.
• D. Ignore the scene.

Answer: (A)

Securing a hazmat incident starts with isolating the area and putting a command structure in place. Establishing a clear perimeter and controlling who can enter or leave the scene minimizes exposure to responders and bystanders, prevents contamination from spreading, and helps preserve evidence for later analysis. At the same time, deploying the incident command system and assigning key roles—Incident Commander to lead, Safety Officer to monitor hazards and PPE compliance, and a Liaison to coordinate with other agencies—provides unified direction, clear accountability, and efficient use of resources from the very start. Without these steps, actions like trying to evacuate everyone without a plan can create chaos and overlook safety priorities; collecting samples without proper PPE endangers responders; and ignoring the scene is dangerous and unacceptable. Starting with a defined perimeter and a structured command ensures safety and coordination as the incident unfolds.
