As a freight inspector, your duties are to inspect shipments to ensure that they are packed and secured correctly and loaded in the proper container. You also make sure that contents are in compliance with all freight regulations. You review cargo manifests and file reports after a shipment ua complete, inspect them when they arrive at a shipping location, such as a port, rail yard or freight depot, and advise shipping crews whenever freight is not stored correctly so that they avoid accidents. Your responsibilities differ slightly if you are dealing with ships, trucks, or trains.
