Where can you find the four-digit UN identification number in the ERG?

• A. Blue bordered pages in the ERG
• B. Yellow bordered pages in the ERG
• C. Green highlighted sections
• D. Red bordered pages in the ERG

Answer: (B)

Understanding how the ERG is organized helps you locate critical information fast. The four-digit UN identification number is listed in the yellow bordered pages, which serve as the index of substances with their UN numbers. This arrangement lets you quickly find the correct UN number for a material and then use that to jump to the appropriate emergency guide in the orange pages for the specific hazards and actions. The other colored sections contain different reference material, so the UN number lookup is specifically found in the yellow pages.
