Shipyard Exposure Index
Comprehensive database of U.S. naval and commercial shipyards with documented asbestos exposure, workforce statistics, and compensation claim guidance.
American shipyards employed millions of workers during the 20th century, with peak employment during World War II and the Cold War. Asbestos was used extensively in ship construction, repair, and overhaul operations from the 1930s through the 1980s, creating one of the largest occupational exposure cohorts in U.S. history.
Documented shipyard facilities: 25+
Peak combined employment: 1.5+ million workers (WWII)
Primary exposure period: 1940-1980
Asbestos applications per vessel: 300+ distinct uses
How Shipyard Workers Were Exposed
Asbestos was used in virtually every shipboard system:
Insulation — Pipe covering, boiler lagging, turbine wrapping
Fireproofing — Bulkhead panels, deck underlayment, cable coating
Gaskets — Valve packing, flange seals, pump components
Structural — Adhesives, cements, caulking compounds
Workers in all shipyard trades faced exposure, but those in engine rooms, boiler spaces, and insulation work faced the highest concentrations—often exceeding safe limits by 100x or more.
Naval Shipyards
U.S. Navy shipyards conducted construction, repair, and overhaul of naval vessels. These facilities operated under federal authority and maintained detailed employment records now available through FOIA requests.
