Where the content comes from
The guide content is the ERG 2024, developed by the U.S. Department of Transportation (PHMSA), Transport Canada and the Secretariat of Infrastructure, Communications and Transportation of Mexico (SICT), reproduced without change. Hazora is an independent app and is not an official ERG publication; it is not affiliated with or endorsed by any of these agencies.
For the initial phase only
The ERG is meant for the initial phase of a transportation incident. Hazora does not replace your agency’s procedures, your training, the shipping paper or the emergency response number it lists.
