Blue-bordered pages in the ERG provide:

• A. an index of dangerous goods in alphabetical order by material name
• B. a table of contents for the ERG
• C. an index of emergency phone numbers
• D. a glossary of terms

Answer: (A)

Blue-bordered pages in the ERG are the index of dangerous goods organized alphabetically by the material’s proper shipping name. This quick-reference index lets responders directly locate the exact entry for the material involved, and that entry points to the corresponding orange pages that contain the initial emergency response information for that material.

This organization is practical in a real incident because you can move straight from identifying the material to finding the specific actions to take, such as recommended isolation distances and protective measures. Other sections serve different purposes: a table of contents helps you navigate the whole book, a glossary defines terms, and emergency contact numbers are listed in a separate index or section.
