If a 4-digit ID number is observed on an orange panel, which ERG section should you look at FIRST for guidance?

• A. Blue-bordered material index
• B. Orange-bordered section
• C. Green-bordered section
• D. Yellow-bordered section

Answer: (D)

When you see a four-digit ID on a hazmat label, you don’t start with general guidance. You first use the blue-bordered material index to look up that ID and find the corresponding guide number. That guide number then points you to the orange-bordered section, which contains the material’s specific initial response information, hazards, and recommended actions. The yellow-bordered section offers general information like initial isolation distances, but you rely on the blue index to identify the correct orange guide first.
