USL&H And Heat Risk: Protecting Marine Workers In Extreme Temps
July 15, 2025
Rising temperatures present increasing workplace safety risks for marine workers who operate on or near the water, making USL&H coverage a vital consideration for insurance agents serving this sector. As heat-related exposures become more frequent and severe, agents must understand the unique challenges their recreational marine clients face and ensure they have the proper protections in place.
Heat Exposure and Marine Work
Heat exposure is a serious and growing concern for workers involved in vessel loading, repairs, or operations. Heat-related illnesses such as heat stroke, heat exhaustion, and dehydration are significant threats that can compromise safety and productivity.
Marine work sites amplify these risks due to several environmental factors. Reflective surfaces like water and metal decks increase heat absorption. High humidity levels reduce the body’s ability to cool through sweat evaporation. Minimal shade on docks and vessels limits workers’ chances to cool down during breaks. These combined elements create a hazardous environment that demands careful attention.
Understanding When USL&H Applies
Understanding when USL&H coverage applies is essential for insurance agents advising marine employers. The United States Longshore and Harbor Workers’ Compensation Act (USL&H) provides federal workers’ compensation benefits to maritime employees involved in loading, unloading, repairing, or building vessels on navigable waters.
Employers who may be required to carry USL&H coverage include dock builders, marine contractors, and companies that perform boat repairs near or on the water. This coverage helps fill gaps left by state workers’ compensation policies, especially in complex maritime environments where jurisdiction can be unclear.
Why Heat Risks Require Coverage
Heat-related injuries are covered under USL&H policies, highlighting the importance of this coverage for marine employers facing heat stress hazards. Standard workers’ compensation may not address maritime-specific risks, leaving employers vulnerable to uncovered claims.
Without proper USL&H coverage, employers risk substantial legal and financial consequences, particularly during the warmer months when heat-related incidents spike. Failing to carry USL&H coverage can expose marine businesses to lawsuits and costly penalties that threaten their operations.
