Pittsburgh Asbestos Exposure & Mesothelioma

Pittsburgh was the steel capital of the world for a century. U.S. Steel, Jones & Laughlin, Westinghouse Electric, and Carnegie Steel mills lined the Monongahela, Ohio, and Allegheny rivers — all using asbestos in furnace linings, boiler insulation, and throughout their massive facilities from the late 1800s through the 1980s.

Steel Mill Asbestos Exposure

Pittsburgh steel mills used asbestos throughout their operations — in blast furnace linings, coke oven insulation, ladle linings, boiler insulation, and throughout the electrical systems of rolling mills. Workers in the most hazardous positions were bricklayers and boilermakers who installed and maintained refractory linings containing asbestos, as well as pipe coverers and insulators who handled asbestos products daily.

The decline of Pittsburgh steel in the 1980s shut down most of these facilities, but the mesothelioma latency period of 20–50 years means that former mill workers are still being diagnosed today — decades after their exposure. Pennsylvania’s 2-year discovery rule means the statute of limitations starts at diagnosis, not at the time of exposure.

Can former Pittsburgh steel workers file mesothelioma claims?▼

Yes. Former steelworkers, boilermakers, pipefitters, and maintenance workers at Pittsburgh-area mills can file claims against asbestos product manufacturers (insulation, refractory, and gasket manufacturers) within 2 years of a mesothelioma diagnosis. The Allegheny County Court of Common Pleas handles Pittsburgh-area asbestos cases. Many former steel workers also qualify for multiple asbestos trust fund claims simultaneously — often from manufacturers of the specific insulation or refractory products used at their mill.
