PHMSA's 2020 Emergency Response Guidebook provides first responders with a go-to manual to help deal with hazmat transportation accidents during the critical first 30 minutes.
DOT's goal is to place an ERG in every public emergency service vehicle nationwide. To date, more than16 million free copies have been distributed to the emergency response community through state emergency management coordinators. Members of the public may purchase a copy of the ERG through the GPO Bookstore and other commercial suppliers.
