Upon arrival at a hazardous material incident involving a truck, you locate the 4-digit UNID number on an orange panel. You should look first in the ERG for guidance in the?

• A. Yellow-bordered section
• B. Blue section
• C. Green highlighted entries
• D. Orange sections

Answer: (A)

The key idea is knowing how the ERG organizes urgent actions by color-coded sections. After you identify the UN identification number from the placard, the first guidance you need on scene is how far to isolate and what protective actions to take. That information is found in the yellow-bordered pages, which contain the Initial Isolation and Protective Action Distances for each material. These distances tell you how large a danger zone to establish and whether to evacuate or shelter in place for occupants and responders. The other sections provide hazard details or material listings, but the immediate priority at arrival is to set the safe perimeter using the yellow pages.
