If the Crane Was Shore-Based, a Different Safety Standard Applies — and That Can Matter
OSHA's maritime industry overview describes the industry as including "the construction, repair, and scrapping of vessels, as well as the movement of cargo and other materials," and lists hazards including "slips, trips, and falls, machinery and equipment hazards, hazardous chemicals, confined/enclosed spaces, and fire hazards." That page is at OSHA's maritime industry overview.
If you were hurt on shore, handling cargo in the yard, moving it to or from a truck or train, or using and maintaining terminal equipment, the governing standards are usually OSHA's marine terminal rules. 29 C.F.R. § 1917.1(a) applies them to "employment within a marine terminal," including "the loading, unloading, movement or other handling of cargo, ship's stores or gear within the terminal or into or out of any land carrier, holding or consolidation area," and other activity tied to the terminal's operation, "such as the use and routine maintenance of facilities and equipment." All cargo transfer done with shore-based material handling devices is regulated by that part. The rule also carves out some facilities, including those used solely for bulk storage and transfer of liquids and gases.
If you were hurt aboard ship, a different part applies. 29 C.F.R. § 1918.1(a) covers "longshoring operations and related employments aboard vessels," while again sending shore-based cargo transfer back to the terminal rules.
The practical point is that a crane lift, a forklift on the apron and work in a ship's hold may each sit under a different set of safety standards. For an injured worker, knowing which one governed the task helps frame what conduct was expected and who was responsible for it.
A broken safety rule, on its own, does not prove anyone was at fault. The rule describes how the work was supposed to be done. Whether it was broken, and whether that connects to your injury, are questions your own facts answer, and they are part of what an attorney can help sort out.
