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

The primary function of the Emergency Response Guidebook (ERG) is to provide first responders with essential information to effectively manage hazardous materials incidents. The ERG includes guidelines on how to safely approach and control emergencies involving hazardous substances, offering valuable information such as hazard identification, protective measures, and emergency response actions. This resource is crucial during incidents where hazardous materials are involved, ensuring that responders can make informed decisions quickly and safely to protect public health and the environment.

This focus on emergency management makes it distinct from options that discuss weather information, chemical safety protocols for manufacturers, or transportation logistics. Each of those aspects is important in their respective contexts but does not contribute to the immediate needs of first responders in hazardous materials scenarios.
