What is the purpose of the Emergency Response Guidebook (ERG)?

The Emergency Response Guidebook (ERG) is designed specifically to provide critical information for first responders when they encounter incidents involving hazardous materials. This guide serves as an essential tool for quickly determining the nature of the hazardous material involved and offers guidance on how to respond effectively to mitigate risks to both the public and the environment.

The ERG includes important data such as emergency contact numbers, evacuation distances, and recommended protective measures based on the type of hazardous material. This immediate access to vital information can significantly improve the safety and effectiveness of the response efforts during a hazardous materials incident. Therefore, its primary function aligns closely with aiding first responders in managing emergencies involving hazardous substances.

While the other options touch on aspects related to hazardous materials, they do not encompass the primary focus of the ERG, which is centered on emergency response rather than environmental audits, legal implications, or training for hazardous waste disposal. The ERG is clearly established as an essential resource for first responders, making option B the most appropriate answer.
