What must a shipper do with hazardous materials?

Answer: B — Package, mark, and label

The responsibility of a shipper when dealing with hazardous materials includes the critical tasks of packaging, marking, and labeling. Proper packaging ensures that hazardous materials are secured and protected during transportation to prevent leaks or spills that could pose a risk to health and safety. Accurate marking involves indicating the contents and handling requirements, which is vital for informing handlers and transporters of the inherent risks. Labeling provides important safety information, such as warnings about the nature of the materials and instructions on how to handle them safely. These processes are essential for compliance with various regulations, including those set forth by the Department of Transportation (DOT) and the Environmental Protection Agency (EPA). They help ensure that hazardous materials are transported safely, minimizing the risk of accidents and environmental impacts during transit. The requirements for hazardous materials packaging, marking, and labeling are well-defined in federal regulations, reflecting the importance of these actions in the overall management of dangerous goods in transportation.
