Final answer:
Typically, operators are required to inspect cargoes and their securing devices, except in exceptional circumstances such as directives from law enforcement. Inspections are crucial for safety and adhering to regulations, and customs officers use high-tech scanning to check cargo contents.
Step-by-step explanation:
The only circumstance in which you are not required to inspect your cargoes and load securing devices would be an unusual one, such as an emergency or directive by law enforcement. Generally, operators are responsible for regularly inspecting their cargo and the devices securing them to ensure safety and compliance with regulations. Customs officers use various means, like gamma ray, x-ray, or neutron-scanning devices, to check the contents of vehicles, as mentioned in Figure 32.2. Regular inspections are part of the protocol to avoid issues like transportation of contraband or ensuring that animals and stowaway water transportation equipment like rubber tires are secured properly inside cargo holds. While securing loads on vehicles, trails, or roadsides, the aim is to minimize the risk of accidents or damage to the cargo.
