Why Power Plants Are Linked to Mesothelioma

Electric power plants were among the most asbestos-intensive workplaces in American industry. From the 1920s through the late 1970s, virtually every coal-fired, oil-fired, gas-fired, and nuclear generating station in the United States was built with asbestos as a standard material — because the entire purpose of a power plant is to generate, contain, and move high-pressure, high-temperature steam, and asbestos was the era’s insulation of choice for exactly those conditions.

The workers who operated and maintained these plants were exposed to asbestos fiber every time insulation, gaskets, or packing were disturbed — which, in a working power plant, was constant. Decades later, many of these workers are being diagnosed with mesothelioma, asbestos-related lung cancer, and asbestosis, because these diseases typically develop 20 to 50 years after exposure.

Where Asbestos Was in a Power Plant

Boilers. The boiler was the heart of asbestos exposure in a power plant. Boilers were wrapped in asbestos block insulation, lined with asbestos-bearing refractory, and sealed with asbestos gaskets at every manhole, handhole, and access point. Boiler maintenance — retubing, refractory repair, insulation replacement — released heavy concentrations of asbestos fiber.

Steam, feedwater, and condensate piping. Miles of piping ran through every generating station, insulated with asbestos pipe covering (calcium silicate, magnesia, asbestos-cement, and asbestos-cloth wrap). Cutting, removing, and rewrapping this insulation during maintenance was a routine source of exposure.

Turbines and generators. Steam turbines were lagged with asbestos insulation on their casings, and sealed with asbestos gaskets at flanged joints. Turbine overhauls required removing and reinstalling this insulation.

Valves and pumps. Every valve was packed with asbestos valve-stem packing; every pump used asbestos shaft packing and flange gaskets. Repacking valves and pumps was daily maintenance work.

Electrical switchgear. High-voltage switchgear, breakers, and control panels used asbestos board and asbestos-filled phenolic components, disturbed by plant electricians during service.

Power Plant Workers at Risk

  • Stationary engineers and boiler operators — overall plant operation and boiler-area duties
  • Firemen and water-tenders — boiler operation and monitoring
  • Plant maintenance mechanics and millwrights — equipment overhaul and repair
  • Plant pipefitters — steam and feedwater piping work
  • Plant electricians — switchgear and motor maintenance
  • Insulators — pipe and equipment insulation installation and tear-out
  • Boilermakers — boiler construction, retubing, and repair
  • Instrument technicians, ash handlers, and laborers — plant-wide bystander exposure

Even office, security, and support staff working inside a generating station could inhale airborne asbestos fiber circulating through the plant.

Types of Power Plants Where Exposure Occurred

Coal-fired, oil-fired, and gas-fired steam stations shared essentially identical asbestos construction. Nuclear generating stations — despite their modern reputation — also used extensive asbestos insulation on their steam systems, turbines, and piping, exposing the same trades. Utility, industrial, cogeneration, and municipal power plants all followed the same asbestos-era building practices.

The asbestos-containing boilers, turbines, insulation, gaskets, and packing used in power plants were made by manufacturers — including Babcock & Wilcox, Combustion Engineering, Foster Wheeler, General Electric, Westinghouse, Johns-Manville, and Owens-Corning — many of which have established asbestos bankruptcy trust funds. A power plant worker diagnosed with an asbestos-related disease may be able to file claims against multiple manufacturers at once.

If you worked at a coal, oil, gas, or nuclear power plant during the asbestos era and were exposed to asbestos insulation, boiler refractory, gaskets, or packing — and have since been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer — you may have legal rights.
