About this app

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.

App works really well, faster then the book, and I like that it saves recent searches for when you need to quickly switch between a few things. The evacuation map is GREAT. On the down side I noticed the P for polymerization is missing on some chemicals, IE 119, this is a pretty big issue, and one I hope the developers look into quickly.

This app use to be great. Use it for my hazmat classes and also refresher class every year. But this bug will not go away cannot look up placards or railway car by types or over the road because the black dot pushes everything off the page. Uninstalled and reinstalled still does the same thing please fix this problem. I would love to use this again for emergency responses.

Such a great tool. We (nowadays) will most likely have our phones with us at all times, as opposed to the book itself. This app is wonderful to use, is well executed, and has an easy learning curve. I recommend it to all my students when teaching hazardous Materials courses. Well done PHMSA!
