The guide numbers used by responders come from which guide?

• A. The ERG
• B. The DOT ERG
• C. The NFPA guide
• D. The Hazmat Handbook

Answer: (B)

Responders rely on a standardized set of guide numbers that point them to the right information at a hazmat incident. Those numbers come from the Emergency Response Guidebook, published by the U.S. Department of Transportation. The ERG is organized so each guide number corresponds to a specific material or hazard class, directing responders to the initial actions, hazards, and protective measures they should take right away. This makes the DOT Emergency Response Guidebook the authoritative source for the guide-number system used in the field. Other references like the NFPA 704 labeling system and generic hazmat handbooks cover different, non‑numeric identification schemes, so they aren’t the source of the guide numbers responders use.
