PHMSA’s Emergency Response Guidebook (ERG) is the go-to resource for first responders during the initial phase of a dangerous goods or hazardous materials transportation incident. The ERG app is a valuable companion, based on the latest edition of the ERG, to help responders quickly access critical information at their fingertips. The app features an indexed list of dangerous goods, including their associated ID number, general hazards, and recommended safety precautions. In practical scenarios, such as responding to an overturned tractor trailer displaying a DOT hazmat placard, emergency responders can use the app to quickly identify the material associated with the placard and get guidance on how to respond effectively. Full versions available in English, French, and Spanish.
