What does the ERG Blue Pages list?

• A. UN/NA ID number (numeric)
• B. Action guides: hazards, public safety, response
• C. Chemical names (alphabetical)
• D. Initial isolation and protective distances

Answer: (C)

The Blue Pages of the Emergency Response Guidebook (ERG) primarily provide a numerical list of UN (United Nations) and NA (North American) identification numbers, along with the corresponding chemical names in alphabetical order. This section is vital because it allows emergency responders to quickly identify hazardous materials based on their identification numbers. In situations where the name of a chemical is known but not its specific properties or hazards, responders can refer to the Blue Pages to locate pertinent information and ensure a prompt and effective response to hazardous materials incidents. The organization of these entries in alphabetical order aids in rapid access during emergency situations.

The other options pertain to different sections of the ERG, specifically dealing with action guides for hazards, public safety, and recommended response measures, as well as details about isolation distances, which are found in other parts of the guide but not in the Blue Pages.
