Latest version of Emergency Response Guidebook now available

Updated May 21, 2024

The latest version of the Emergency Response Guidebook (ERG) is now available.

It contains lifesaving information that is used to respond to hazardous materials incidents. That’s why it’s important that companies use the most up-to-date version of the book — the 2024 version — to enhance safety and avoid violations, according to J.J. Keller & Associates, which sells trucking safety equipment and information.

Keller said in a statement the ERG is also the easiest way to help satisfy the DOT's requirement that hazardous materials shipments be accompanied by emergency response information (49 CFR 172.602).

Some of the key changes to the 2024 ERG include:

  • Added QR codes that offer quick access to incident reporting information
  • Added response information for lithium batteries and electric vehicles
  • Expanded 15 guides, including 115, 131, 140, 153 and 171
  • Updated several tables and charts located in the front of the ERG
  • Gave chemical and biological warfare agents its own section
  • Added 11 new and removed 8 obsolete UN/ID numbers to harmonize with the Hazardous Materials Regulations

“The ERG is a useful tool not only for first responders, but anyone who ships, loads or transports hazmat, as well as those who handle chemicals,” said Michael Atkinson, J. J. Keller & Associates, Inc. hazardous materials subject-matter expert. “It’s important to have the most recent emergency response information to avoid violations.”

J. J. Keller offers the 2024 ERG in pocket size or standard, softbound or spiral-bound formats, and in Spanish.

The company is now shipping the 2024 ERG. For more information, visit
