Major changes to the 2024 ERG could affect your operations
The Pipeline and Hazardous Materials Safety Administration (PHMSA) has published significant updates to the Emergency Response Guidebook (ERG) from 2020 to 2024. Organized by color-coded sections – White, Yellow/Blue, Orange, and Green – these changes reflect the latest advancements in emergency response protocols and safety measures.
In addition to minor editorial revisions aimed at improving accuracy and consistency throughout the guidebook, PHMSA has introduced innovative features to enhance user accessibility and facilitate swift response during emergencies. Notably, QR codes have been incorporated into the back cover of the hard copy version of 2024 ERG, providing instant access to critical incident reporting information for first responders on the scene.
