Emergency Response Guidebook (ERG)
What it is
PHMSA's ERG2024 is a first-responder reference for the initial phase of transportation incidents involving hazardous materials or dangerous goods.
Why it matters for patrol
Deputies may reach a truck crash or suspected hazardous-materials release before fire or HazMat personnel. The ERG helps identify potential hazards and initial safety precautions while coordinating specialist assistance.
Quick summary
The guide organizes dangerous goods by identification number and name, with emergency-response guides describing hazards and initial precautions. The free mobile apps put this reference within easy reach in the field.
The guide link opens PHMSA's official PDF access page. App links are listed on the official PHMSA mobile-app page.
Use current training, agency policy, and fire/HazMat direction. The ERG supports initial response; it does not replace specialized training or a full incident assessment.
