DOT Hazardous Materials Function-Specific: Marking and Labeling

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 unloadinghazardous waste manifesting.


The marks and labels required on hazardous material packages communicate essential information to everyone who handles these materials in your supply chain, including personnel at your site, carriers, customers, emergency responders, and disposal facilities. This Function-Specific training is required for employees who determine what marks or labels must be placed on packages, as well as employees who place marks or labels on packages of hazardous materials. It is recommended for anyone who must understand the information on packages, such as those who receive hazardous material shipments, as well as emergency responders.


In this session, you will learn:

  • Which of your shipments must bear marks and labels, and which are exempt
  • How to determine if your shipments qualify for reduced marking requirements, if they are small quantities, limited quantities, or consumer commodities
  • The DOT’s required marks and labels that shippers must ensure are on each package of hazardous materials
  • How to determine which special marks are required for shipments of hazardous substances, generic shipping names, marine pollutants, combination packages holding liquids, hazardous waste, overpacks, salvage drums, and other materials with unique requirements
  • What special handling labels are, and when you must apply them
  • How to mark and label packages that contain different chemicals or products
  • What subsidiary labels are, and when to use them
