About PHMSA Emergency Response Guide (ERG)
The Emergency Response Guidebook (ERG) is developed by the US Department of Transportation (DOT), Transport Canada, and the Secretariat of the Communications and Transportation of mesico (SCT). The ERG is intended to be used by firefighters, police, and other emergency services personnel who may be the first to arrive at the scene of a transportation incident involving hazardous material.
It is primarily a guide to aid first responders in
- quickly identifying the specific or generic classification of the material(s) involved in an incident, and
- protecting themselves and the general public during the initial response phase of the incident
ERG is updated every four years to accommodate new products and technology.
