The 4-digit ID number on an orange placard is used to locate which type of information in the ERG?

• A. Weather data
• B. Protective action distances
• C. Firefighting tactics
• D. Shipping routes

Answer: (B)

The four-digit UN identification on the orange placard is your fast key to the right entry in the ERG. That entry provides the immediate public safety information for that material, centered on protective action distances—the recommended distances to evacuate or shelter people to reduce exposure during a release. The numbers guide you to apply the correct boundaries based on the substance and release scenario, which is the crucial first step in protecting responders and the public. Weather conditions can influence these distances, but the PADs themselves come from the material’s characteristics in the ERG. Other topics like weather data, firefighting tactics, or shipping routes are part of the broader resources, but they aren’t what you locate first using the placard’s identification.
