The ERG Blue Pages are organized by which criterion?

The ERG Blue Pages are organized by which criterion?

• A. Listed by UN number
• B. Listed by name (alphabetically)
• C. Generic information
• D. Usage guidelines

Answer: (B)

Blue Pages act as an alphabetical index by chemical name. This layout lets you quickly locate a material when you know its name, and then you can follow the entry to the corresponding UN number and the applicable guide in the Yellow Pages. The Yellow Pages are the section organized by UN number, which is why the Blue Pages point you there rather than listing by UN number themselves. The Blue Pages aren’t meant for generic information or usage guidelines; they’re the name-based index that links you to the right UN entry and guidance in the Yellow Pages.
