First responders refer to this guide as the ERG; it’s a go-to manual to help manage hazardous material incidents for the first 15 minutes to an hour.
It’s compiled by DOT/PHMSA and distributed federally to the states to the local jurisdictions. Every jurisdiction should have an ERG in every vehicle that responds to incidents.
The guide is updated every four years; 2016 is the most current edition. It’s available for PDF download and as a free, mobile web app from the Apple iTunes store (iPhones) and the Google Play website (Android devices). For further information, visit www.phmsa.dot.gov/hazmat/erg-mobile-app.
