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

The primary purpose of the Emergency Response Book, commonly known as the Emergency Response Guidebook (ERG), is to provide essential guidance for first responders at hazardous materials incidents, especially those that occur on highways and railroads. The ERG assists emergency personnel in identifying the hazardous materials involved in an incident, understanding the risks, and determining the appropriate response measures. This includes information on evacuation distances, containment guidelines, and potential health effects associated with exposure to hazardous substances.

The focus on incidents occurring on highways and railroads recognizes that these locations often present unique challenges, such as high traffic volumes and the transportation of various hazardous materials. By centralizing critical information in one resource, the ERG enhances the ability of first responders to make informed decisions quickly, thereby improving safety for both emergency responders and the public.
