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

The primary purpose of the Emergency Response Guidebook (ERG) is to help emergency responders quickly assess risks associated with hazardous materials incidents. The ERG serves as a vital resource during emergencies involving hazardous substances. It provides critical information on how to identify hazardous materials, the potential risks they pose, and the recommended emergency response actions to mitigate those risks.

By referencing the ERG, responders can efficiently determine the necessary protective measures to take, how to manage the situation effectively, and the appropriate steps to protect both themselves and the public. This rapid access to key information supports effective decision-making in high-pressure situations where safety and quick action are paramount.

The other options do not align with the primary focus of the ERG. Shipping schedules, lists of hazardous materials, and shipping costs are not the central objectives of the guide, which is entirely centered around emergency response and safety measures in hazardous material incidents.
