Transportation inspectors help make sure that cargo is moved safely from place to place over land, rail, water, air, or pipeline—especially cargo that might be hazardous to people, property, or the environment (such as fuel, chemicals, or flammable gases). For example, pipeline inspectors might check for corrosion or leaks that could lead to ruptures or chemical spills. Hazardous materials investigators might inspect containers of flammable gases to make sure they are properly labeled, secured, and put in the correct container to remain safe during transportation.
