In the ERG, ID numbers are found in which pages?

• A. Blue pages
• B. Yellow pages
• C. White pages
• D. Orange bordered pages

Answer: (B)

In the ERG, UN/ID numbers are used to identify hazardous materials quickly by a numeric code. Those numbers are found in the Yellow pages, which are organized by UN/ID number so you can locate the exact guide for that substance. Once you find the number, you can read the corresponding material’s recommended actions right away, including initial actions and safety considerations. If you know the substance name instead, you’d use the blue pages, which are organized by material name, not by ID number. The other color sections cover different reference data, but the UN/ID lookup specifically happens in the Yellow pages.
