About Greenville Electric Generating Station
Coal-fired and steam-driven electric generating stations were among the heaviest industrial users of asbestos-containing materials in the United States. Manufacturers supplied asbestos-containing products including gaskets and packing, ceiling tile, and pipe insulation across nearly every operating system at facilities throughout the Midwest, including plants along the Ohio River industrial corridor. These facilities did not use asbestos-containing materials in isolated locations. They integrated ACM into critical infrastructure that workers serviced repeatedly, year after year, for entire careers.
High-pressure steam operating at 1,000°F or above required extensive pipe insulation. Asbestos-containing pipe covering — including calcium silicate pipe insulation and Thermobestos product lines — was the accepted industry standard for decades and was reportedly specified at generating stations along the Ohio River corridor.
Generating stations house flammable coal, fuel oil, lubricating oils, and hydraulic fluids. Building codes required fire-resistant insulation board, spray fireproofing, and structural materials. Asbestos-containing products were specified for this purpose throughout the industry, including at Ohio facilities where Heat and Frost Insulators and UA Pipefitters members allegedly performed installation work.
Boiler operations exceeded 1,000°F, with steam systems at hundreds of pounds per square inch. Gaskets, packing materials, rope seals, and refractory cement had to hold under those conditions. Asbestos-containing products were engineered for these demands. Boilermakers members in Ohio may have encountered these products across multiple generating facilities throughout their careers.
Asbestos-containing materials appeared in electrical panels, wire insulation, arc chutes, circuit breakers, and switchgear throughout these facilities. Trade-name products including spray-applied fireproofing, high-temperature pipe insulation, and Cranite were reportedly present in electrical infrastructure from the boiler house to the control room.
Early generating station construction incorporated asbestos-containing materials in boiler insulation, pipe lagging, and structural fireproofing. Post-World War II electrical demand drove rapid expansion. Ohio generating stations reportedly received large quantities of asbestos-containing insulation products during this era, with union members from the Heat and Frost Insulators and Boilermakers allegedly performing installation work involving these materials. This was peak asbestos use in American industry.
Continued expansion and routine maintenance kept demand high for asbestos-containing products from gaskets and packing manufacturers. Repeated maintenance and repair work disturbed existing asbestos-containing insulation — often without any protective measures. Workers at this stage frequently had no knowledge of the hazard.
OSHA issued initial asbestos exposure standards in 1972. EPA strengthened regulations through the 1980s and 1990s. Despite those mandates, asbestos-containing materials reportedly remained in place at generating stations well into the 1980s, with many facilities completing ACM abatement only during decommissioning projects (documented in NESHAP abatement records).

Who May Have Been Exposed at Greenville Electric Generating Station
Workers affiliated with Heat and Frost Insulators locals operating in Ohio may carry the highest direct exposure risk of any trade at power generating stations. Their primary tasks placed them in sustained physical contact with asbestos-containing insulation products throughout entire careers. Insulators reportedly worked across the Ohio River industrial corridor, including at Ohio generating stations. Work at generating stations allegedly included: cutting and fitting pre-formed asbestos-containing pipe covering sections — including calcium silicate pipe insulation and Thermobestos formulations — to pipes of varying diameters; mixing asbestos-containing insulating cement and applying it wet to irregular pipe and equipment surfaces; sawing asbestos-containing insulation board to fit structural configurations; stripping damaged or deteriorated asbestos-containing pipe lagging during maintenance outages; applying boiler block insulation; and installing asbestos-containing blanket insulation around valve bodies and fittings.
Pipefitters and steamfitters installed, maintained, and repaired the high-pressure, high-temperature piping systems that move steam throughout generating facilities. Members of the UA Pipefitters — the United Association serving Ohio and portions of the Ohio River industrial corridor — reportedly worked at generating stations where asbestos-containing products were specified on piping systems, valve assemblies, and equipment connections. Work at generating stations allegedly included: cutting and threading pipe in close proximity to asbestos-containing pipe insulation; installing and removing asbestos-containing gasket materials from equipment flanges; replacing asbestos-containing valve packing and equipment seals from gaskets and packing manufacturers; participating in equipment modifications requiring removal of asbestos-containing materials; and stripping and replacing asbestos-containing insulation during maintenance outages. Pipefitters and steamfitters working alongside insulators may have experienced significant bystander exposure in addition to direct contact with ACM.
Boilermakers fabricated, installed, and maintained boiler systems operating at extreme pressures and temperatures. Boilermakers members in Ohio may have worked extensively with asbestos-containing materials on boilers, high-pressure piping, and associated equipment at generating stations throughout the regional industrial corridor. Work at generating stations allegedly included: installing asbestos-containing refractory cement and lining materials on boiler interiors; fabricating and installing asbestos-containing gaskets and packing for boiler fittings; stripping and replacing deteriorated asbestos-containing boiler insulation; working with asbestos-containing rope seals and expansion joint materials; and maintaining and repairing asbestos-containing boiler brickwork and refractory. Boilermakers historically faced among the highest cumulative asbestos exposures of any trade, with exposures often occurring across multiple facilities and jurisdictions over decades-long careers.
Electricians who serviced electrical panels, switchgear, and arc-chute equipment in close proximity to insulation work may have been exposed to asbestos-containing materials without ever touching a single piece of insulation themselves. Control room operators and instrument technicians who worked in areas where other trades disturbed ACM are in the same position. Bystander exposure claims are legally recognized and have resulted in substantial verdicts and settlements in Ohio courts.
Millwrights, machinists, welders, painters, and general laborers who worked at generating stations during the peak asbestos era may also have encountered asbestos-containing materials. Maintenance outages — when multiple trades worked simultaneously in close quarters — created conditions where asbestos fiber concentrations from disturbed ACM could reach every worker in the area, regardless of their assigned task.
Ohio — Filing Deadline & Next Steps
Ohio law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (ORC § 2305.10). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (ORC § 2125.02). The two deadlines run on separate tracks — preserving one does not extend the other.
The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.
Practical first steps
- Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
- Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
- Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
- Speak with an asbestos attorney with Ohio experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.
Asbestos-Related Diseases — Ohio
Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.
Mesothelioma
A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.
Asbestosis
A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for a claim under most trust schedules and civil claims.
Lung Cancer
Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.
Other Recognized Diseases
Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.
If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
Cross-State & Regional Corridor Workers
Workers affiliated with the Heat and Frost Insulators reportedly worked across the Ohio River industrial corridor, including at Ohio generating stations and at plants on the neighboring-state side of the river. Members of the UA Pipefitters — the United Association serving Ohio and portions of the Ohio River industrial corridor — reportedly worked at generating stations where asbestos-containing products were specified. Boilermakers members may have worked extensively with asbestos-containing materials across multiple generating facilities throughout the regional industrial corridor, in Ohio and in bordering states. Boilermakers historically faced among the highest cumulative asbestos exposures of any trade, with exposures often occurring across multiple facilities and jurisdictions over decades-long careers.Data Sources — Ohio
