2012 Emergency Response Guidebook

The DOT Emergency Response Guidebook (ERG) has become the nation’s “most wanted” first response guidance document since its early beginnings in 1973. The ERG is designed to aid first responders in:

(1) Quickly identifying the hazardous material(s) involved in a transportation incident.

(2) Protecting themselves and the general public during this initial response phase of the incident.

The ERG is updated every four years to maintain its reputation as state-of-the-art technical guidance. Since 1996, PHMSA (formerly RSPA) has produced the ERG jointly with counterparts in Canada and Mexico, resulting in one source recognized for use throughout North America.
