The DOT requires that every hazmat employee receive training in three areas: General awareness, Function-Specific, and Safety and Security. When you complete at least one session from each of these required categories, you will be certified according to the requirements of the U.S. Department of Transportation at 49 CFR 172 Subpart H for shipments of hazardous materials by ground. To meet the DOT training requirements for your specific job, you must complete each Function-Specific session that applies to your job—packaging, marking and labeling, shipping papers, bulk loading and unloading, non-bulk loading and unloading, hazardous waste manifesting.
