Within the ERG, what does a Guide Number represent?

The Guide Number in the Emergency Response Guidebook (ERG) serves as a reference point for responders to identify specific information related to hazardous materials. Each number corresponds to a specific substance or group of substances, providing details essential for managing incidents involving those materials.

This information may include potential hazards, recommended firefighting techniques, first aid measures, and spill control procedures. By using the Guide Number, responders can quickly access vital data that helps ensure safety and efficiency during emergency situations involving hazardous materials. This is crucial for minimizing risks to both responders and the public while effectively managing a hazardous incident.

The other options do not accurately reflect the primary purpose of the Guide Number. Regulatory compliance status, disposal costs, and emergency contacts may be important, but they are not directly represented by the Guide Number within the ERG framework.
