PHMSA's 2020 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 ERG is now available as an iPhone and Android app:

There are tutorial videos from the PHMSA on YouTube to give you a brief overview on how to use the guidebooks, charts, iPhone and Android apps.

It is strongly recommended for officers to familiarize themselves with the charts, guides, and apps as it is crucial when responding in the first minutes of a HazMat incident.
