What does the Yellow section in the Emergency Response Guide (ERG) provide?

The Yellow section of the Emergency Response Guide (ERG) provides UN (United Nations) ID numbers, which are crucial for identifying specific hazardous materials during an emergency response situation. Each hazardous substance recognized internationally is assigned a unique UN ID number, allowing first responders to quickly locate pertinent information about the substance in the guide. This quick referencing helps inform responders of the hazards associated with the materials they may encounter and guides their actions to ensure safety.

The other sections of the ERG offer different types of information. The chemical names can be found in other sections, and evacuation or isolation distances are typically located in the Green section. Hazardous materials information is more general and can be accessed through various sections, but the specific identification through UN ID numbers is exclusive to the Yellow section, making it essential for efficient and effective emergency responses.
