The first step upon arrival at a hazardous materials incident is to:

• A. Isolation of the area and prevention of entry.
• B. Identify the spilled or released product.
• C. Victim recovery.
• D. Notification of the hazardous materials response team.

Answer: (A)

The first action is to establish a safe perimeter by isolating the area and preventing entry. This protects you, other responders, and the public from exposure and buys time to plan the next steps. Identifying the spilled product, while important, should come after the scene is secured so responders aren’t put at unnecessary risk. Victim rescue also must wait until it’s safe to operate, and notification of the hazmat team is essential but responds to the need for control and safety established by isolation.
