Final answer:
A hazmat driver must initially receive training before transporting hazardous materials, with recurrent training required every three years by the United States Department of Transportation. Immediate training may also be needed if there are regulatory changes or violations. These training standards ensure knowledge of safe handling and emergency response regarding hazardous materials.
Step-by-step explanation:
A driver that hauls hazardous materials (hazmat) must attend training according to the United States Department of Transportation (DOT) hazardous materials regulations. The regulations state that drivers must be trained before they can transport hazmat and then must receive recurrent training every three years. Additionally, if there are changes to regulations, or if a driver is found to be in violation of hazmat regulations, immediate training is usually required.
These training regulations are designed to ensure that all hazmat drivers understand the potential hazards associated with the materials they are transporting and are aware of proper handling, emergency response, and safety procedures required by the DOT, as well as understanding the Environmental Protection Agency's (EPA) hazardous waste regulations where applicable.
It is important to contrast these requirements with those of animal transportation, which involve different regulations. For instance, documentation of animals' health, behavior, and training might be required by airlines, with forms that need to be submitted in advance of travel. However, such requirements are separate from the hazmat driver training requirements set by the DOT.
