Emergency Response Guidebook (ERG)

This is an online version of the 2008 Emergency Response Guidebook (ERG) which is produced by the USDOT for first responders during the initial phase of a Dangerous goods/Hazardous Materials incident. Have you ever wondered what those four digit numbers on the placards on the side of trucks and rail cars mean? Our online ERG will give you your answer.
