Shipyard workers — including welders, insulation workers, pipefitters, machinists, and general laborers — experienced some of the most intense asbestos exposures of any occupational group in American history. Shipbuilding and ship repair required massive quantities of asbestos-containing materials, and the confined below-deck spaces of ships concentrated airborne fibers to levels that far exceeded what was later recognized as safe. An estimated 4.5 million American workers were exposed to asbestos in shipyards during World War II alone.

History of Asbestos Exposure for Shipyard

American shipyards operated at peak production during World War II, employing hundreds of thousands of workers at facilities in Brooklyn, Philadelphia, Seattle, New Orleans, San Francisco, and dozens of other cities. Asbestos was used throughout every vessel — in boiler insulation, pipe lagging, engine room panels, deck flooring, and fireproofing materials. Workers who cut, sanded, or installed these materials created clouds of asbestos dust in enclosed hull compartments. Industrial hygiene surveys from the 1940s documented fiber concentrations in shipyard spaces that were hundreds of times the modern permissible exposure limit.

Common Asbestos-Containing Products

The following products were commonly used in this occupation and are well-documented in asbestos litigation:

  • Pipe lagging and thermal insulation
  • Boiler and turbine insulation blankets
  • Asbestos cloth, yarn, and rope
  • Gaskets and valve stem packing
  • Deck tiles and flooring materials
  • Engine room bulkhead panels
  • Welding blankets and heat shields
  • Electrical cabinet insulation

Your Legal Rights

Shipyard workers can file claims against the manufacturers of asbestos products used in their work. Because shipyards used products from many different manufacturers, workers frequently qualify for claims against multiple trust funds simultaneously. Civilian shipyard workers may also qualify for Department of Labor occupational disease benefits if they worked on federal contracts. Families of deceased shipyard workers can file wrongful death claims.

Key Facts for Shipyard

  • Shipyard workers have among the highest mesothelioma incidence of any US occupation
  • Major exposure sites: Brooklyn Navy Yard, Philadelphia Naval Shipyard, Puget Sound, Hunter's Point
  • WWII-era workers (exposed in 1940s–1960s) are now in their primary diagnosis window
  • Dozens of shipyard product manufacturers' trust funds remain active for new claims
  • Both civilian and military shipyard workers may access separate compensation streams
