About the ERG

The 2012 edition of the Emergency Response Guidebook (ERG) was developed jointly by the U.S. Department of Transportation, Transport Canada, and the Transportation Secretariat of Mexico for use by all emergency services personnel who respond to transportation incidents involving hazardous materials. It is primarily a guide to assist first responders in the following activities:

  • Quickly identifying the specific or generic classification of the involved materials
