Which section of the ERG provides information about specific substances?

The section of the Emergency Response Guidebook (ERG) that provides information about specific substances is found in the yellow bordered pages for numerical listing and the blue bordered pages for alphabetical listing.

The yellow bordered pages contain a numerical listing of hazardous materials, arranged by their UN (United Nations) numbers. This list allows responders to quickly identify substances based on their assigned UN number, which is crucial during an emergency response to understand the nature of the materials involved.

Conversely, the blue bordered pages offer an alphabetical listing of the same substances. This format enables responders to locate materials based on their common name, which can be particularly useful when a UN number is unknown or unremembered.

Both sections are essential tools for first responders, enabling them to efficiently gather relevant information about the chemical properties, hazards, and recommended safety measures for a wide array of hazardous materials encountered at incidents. By utilizing these sections, responders can make informed decisions and take the appropriate actions to effectively manage the incident.
