Rail carriers who transport hazardous materials in commerce in the U.S. must comply with the Hazardous Materials Regulations. Besides requiring hazmat training for all affected employees, there are regulations related to shipping papers; rail car positioning; package markings, labels, and placards; leaking packages; and shipment acceptance and inspections. This interactive online course discusses the DOT’s “Carriage by Rail” requirements in Subparts A, B, and most of C in Part 174 of the Hazardous Materials Regulations (HMR). This includes general requirements for hazardous material rail shipments, plus requirements specific to the acceptance, inspection, handling, and loading of hazardous material packages. It also covers tank car unloading and the removal and disposition of hazardous materials after delivery.
