The ERG blue pages are organized by which criterion?

The ERG blue pages are organized by which criterion?

• A. Hazard class
• B. UN numbers
• C. Name (alphabetically)
• D. Color code

Answer: (C)

Blue pages are organized by substance name in alphabetical order. This layout lets you locate the exact material quickly when you know the name from a label, SDS, or shipping papers, so you can immediately read the recommended actions and safety measures for that chemical. Organizing by hazard class, UN number, or color code would slow you down or be less reliable in the field, since those cues aren’t as readily identifiable at a incident scene. Alphabetical naming provides the fastest, most direct path to the correct material entry.
