A loader uses hand machinery or heavy equipment to move cargo between transportation vessels and storage warehouses while observing all loading and unloading safety practices. As a loader, your responsibilities include verifying the times that shipments both arrive and depart, as well as entering the relevant information from documents into a computer system. For example, you examine the bill of lading to determine that all the contents of the shipment are present and create detailed inventory lists. Other duties include packaging, labeling, and sending outgoing shipments.
