Which document would you consult to identify the hazard classification and the appropriate emergency response actions at the scene?

• A. Emergency Response Guide
• B. Shipping Papers
• C. Computer Aided Management of Emergency Operations
• D. National Response Center

Answer: (A)

In hazmat scenes, you need a quick reference that translates what you’re dealing with into its hazards and the first actions to take. The Emergency Response Guide is designed for exactly that on-scene use: it links material identities (or UN/ID numbers) to hazard classifications and the recommended initial response actions, including isolation distances, PPE, evacuation, and basic containment steps. Shipping papers provide the material’s name, UN number, hazard class, and emergency contact, but they’re transport documents and don’t give the on-scene hazard classification and action guidance you need right away. CAMEO is a planning/response software, not a single field reference for immediate actions, and the National Response Center is where incidents are reported, not a guide for on-scene actions. So the document you’d consult to identify hazard classification and the appropriate emergency response actions at the scene is the Emergency Response Guide.
