When transporting both hazardous and non-hazardous materials, what must your bills do?

When transporting both hazardous and non-hazardous materials, it is essential for the bills of lading to identify the materials accurately in compliance with regulations. The correct choice emphasizes that hazardous materials must be marked appropriately in the hazardous materials (HM) column of the shipping documents. Specifically, identifying hazardous materials by the designation of "X" or "RQ" (Reportable Quantity) serves a critical regulatory purpose. The "X" indicates that the substance is classified as a hazardous material, while "RQ" denotes that the quantity of that material being transported meets or exceeds the threshold that requires special attention due to its potential danger.

This identification is crucial for ensuring that all personnel involved in the transport chain are aware of the presence of hazardous materials, allowing for appropriate handling, storage, and emergency response procedures. Such clear identification supports safety measures not only for the transporters but also for the public and the environment.

This specificity regarding hazardous materials ensures compliance with the Department of Transportation (DOT) regulations, fostering effective communication and safety practices in the transportation of goods.
