Hazmat (HM-126F)
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
HM-126F is the federal training rule for hazardous-materials handlers - both employers and employees who load, unload, transport, prepare, mark, or document a hazmat shipment must complete general awareness, function-specific, safety, security awareness, and (for security-sensitive materials) in-depth security training. Codified at 49 CFR §172.704. Training must be repeated every three years. The hazmat carrier and any drivers involved with placardable shipments are subject. Records must include name, certification date, materials covered, and trainer information. Failure to train is a frequent compliance-review finding. Hazmat training is separate from the CDL hazmat (H) endorsement requirements.
