According to NFPA, what is expected of awareness level personnel responding to a hazmat breach?

• A. Recognize Hazmats or WMDS
• B. Call for Trained Personnel
• C. Secure the scene
• D. Establish a perimeter

Answer: (D)

Awareness level responders are there to keep people safe by quickly identifying that a hazmat situation exists and taking immediate protective actions until trained personnel arrive. The best action is to establish a perimeter around the incident. Creating an outer boundary limits access, reduces exposure risk for bystanders and responders, and helps preserve the scene for evaluation and response. Recognizing the presence of hazmat and calling for trained personnel are essential steps, but establishing a perimeter is the concrete action that demonstrates scene control at the awareness level. In short, the outer boundary is the practical first-line safeguard that aligns with their role.
