In the context of emergency response, how are the orange pages most commonly used?

The orange pages of the Emergency Response Guidebook (ERG) are specifically designed to provide crucial hazard and emergency response information for various hazardous materials. When responders encounter an incident involving hazardous substances, the orange pages serve as a primary resource for identifying the specific risks associated with those materials and outlining appropriate safety measures and emergency protocols.

This segment of the ERG details essential data such as potential hazards, the behavior of the substance, and recommendations on how to manage emergencies related to the material in question, including evacuation distances and protective measures. The comprehensive approach helps ensure that responders can act swiftly and effectively, mitigating risks to both the public and the environment during an emergency.

Other options, while related to emergency response information, do not align with the specific purpose of the orange pages. For example, identifying the material is typically associated with the yellow or blue pages, regulatory policies fall outside the scope of immediate emergency response, and first-aid instructions are generally found in a different context or document rather than in the ERG.
