What type of cargo must employers be allowed to move under the hook?

Employers must be allowed to move heavy lifts, dunnage, lining material, and more under the hook because these types of cargo typically require specialized handling equipment and techniques. The term "under the hook" refers to the area directly beneath a crane or lifting device where cargo is rigged and lifted. Heavy lifts and materials like dunnage (which is used to protect cargo during transport) often exceed the weight limits of manual handling and need mechanical assistance for safety and efficiency. The regulations governing cargo handling emphasize the importance of proper equipment use and safety measures in the transportation industry, especially for cargo that could cause injuries or damages if not handled correctly.

Other options restrict the types of cargo that can be handled inappropriately. For instance, only allowing light-weight cargo or cargo that can be manually lifted would undermine the operational capabilities and efficiencies that cranes and similar equipment are designed to provide. Similarly, limiting it to dry goods and personal effects overlooks the diversity and demands of various cargo types that require handling under the hook. Therefore, the inclusion of heavy lifts and other specific materials in this context best reflects the range of cargo applicable for such operations.
