Final answer:
In the shipping and transportation of hazardous materials, both the shipper and carrier have responsibilities to ensure correct naming, labeling, and marking as per the DOT and EPA regulations.
Step-by-step explanation:
The responsibility to ensure that hazardous materials (hazmat) are correctly named, labeled, and marked falls on various parties involved in the shipping and transportation process, according to the United States Department of Transportation (DOT) hazardous materials regulations. These regulations, which enforce proper handling and identification of hazmat, require the shipper to accurately name, label, and mark the materials per the classification requirements. However, it is also incumbent upon carriers to verify these details before transportation. This dual-check system is crucial for safety and compliance with the law. Additionally, the Environmental Protection Agency (EPA) has hazardous waste regulations that must be followed when dealing with certain types of hazardous materials.
