Which of the following is NOT a responsibility of shippers for communicating the risk of hazardous materials?

Shippers have several crucial responsibilities when it comes to the safe transportation of hazardous materials, primarily focused on providing clear communication about the associated risks. Among these, providing proper shipping papers ensures that all necessary information about the hazardous materials is documented and accessible to those involved in the transport process. Labeling packages correctly is vital as it visually communicates risks and handling requirements to anyone involved. Similarly, using placards is essential for signaling risks associated with certain materials to emergency responders and others who may encounter the shipment.

Conducting daily inspections, however, does not fall under the responsibilities of shippers. This task is generally more aligned with carriers or those in charge of the actual transportation of the materials. The shipper's role is to prepare and provide information and packaging that communicates hazards effectively, rather than to inspect the transportation vehicle or conditions on a regular basis. This is why identifying the responsibility that does not belong to shippers leads to the correct choice.
