PHMSA's Emergency Response Guidebook (ERG) provides first responders with a go-to manual to help deal with hazmat transportation accidents during the critical first 30 minutes.

The Outreach and Training Branch develops and makes Hazardous Materials Training Publications available that make it easier to understand and comply with the Hazardous Materials Regulations (HMR).
