Weirton Steel employees exposed to asbestos
Steel manufacturing demands continuous extreme heat across every stage of production, from coking and iron making through rolling and finishing. For much of the twentieth century, asbestos was the standard material used to insulate and fireproof the equipment that kept those processes running. Blast furnaces, hot blast stoves, coke ovens, boilers, steam distribution systems, rolling mills, turbines, and electrical switchgear throughout the Weirton facility all relied on asbestos-containing insulation, gaskets, packing materials, and refractory products.
As those materials aged over years of continuous operation, or were disturbed during maintenance and equipment rebuilds, microscopic asbestos fibers were released into the air where workers throughout the facility could inhale them. Industry research confirms that steel mills widely used asbestos insulation on pipes, boilers, furnaces, and processing equipment throughout the 1940s, 1950s, 1960s, and 1970s, and Weirton was among the largest and most active steel operations in the country during that period.
Workers across a broad range of job categories at Weirton Steel may have been exposed to asbestos, including:
- Blast furnace and coke oven workers
- Pipefitters, plumbers, and boilermakers
- Millwrights, electricians, and machinists
- Welders, maintenance mechanics, and insulators
- Crane operators, powerhouse workers, and laborers
- Engineers, supervisors, and office staff who entered production areas
How Weirton Steel workers were exposed
Most workers at Weirton Steel were not handling raw asbestos directly. Exposure occurred through contact with asbestos-containing materials already built into the facility's equipment, insulation systems, and building infrastructure. Maintenance crews, pipefitters, and boiler operators faced the most concentrated exposure because their daily work required them to cut into, remove, replace, or repair insulated components throughout the mill.
Common situations where exposure occurred included removing or replacing pipe insulation, repairing boilers and steam lines, replacing gaskets and valve packing, performing furnace maintenance, cleaning mechanical rooms, and working during mill shutdowns and structural rebuilds. When older sections of the facility were demolished or renovated, asbestos-containing construction materials in walls, ceilings, and floors added another layer of exposure for anyone working nearby. Even workers whose primary duties kept them away from heavy maintenance could accumulate significant exposure simply by spending years in areas where asbestos dust had settled on surfaces and equipment throughout the plant.
