Power Plant Workers and Asbestos Exposure Risks
Working at a power plant before the mid-1980s usually meant working around asbestos. Decades later, power plant workers are still receiving diagnoses for mesothelioma, lung cancer and asbestosis. We help workers and their families understand exposure histories and potential compensation options.
How Power Plant Workers Received Asbestos Exposure
Asbestos became the material of choice for power plants because no other material handled extreme heat, steam pressure, electrical insulation demands and fire risk as effectively. From the 1930s through the early 1980s, power plant operators used asbestos to build the core infrastructure of every major plant in the country.
- Coal-fired plants used asbestos most heavily, packing boiler walls, turbine casings and refractory linings with asbestos insulation to manage temperatures that regularly exceeded 1,000 degrees Fahrenheit. Companies also lined ash-handling equipment with asbestos to withstand the abrasive, high-heat conditions of coal combustion.
- Natural gas plants relied on asbestos for turbine lagging and gasket and packing materials throughout their piping systems.
- Nuclear facilities used asbestos to insulate reactor containment structures, steam generator components and valve packing.
- Oil-fired plants depended on asbestos for boiler insulation and pipe lagging throughout the facility.
The most exposure came from hands-on tasks, including cutting insulation blocks, scraping asbestos cement off boilers and turbines, replacing rope packing and gaskets, mixing dry insulating cement, blowing in loose-fill insulation and grinding refractory bricks. This disturbed the material and dispersed fibers into the air.
The setting worsened asbestos exposure conditions. Turbine halls, boiler rooms and reactor buildings were enclosed spaces with limited ventilation. Airborne fibers accumulated in those environments at concentrations well above what workers would have encountered outdoors. A 2010 study published in the Journal of Occupational Medicine and Toxicology found that power generation workers averaged 20 years of cumulative asbestos exposure across their careers.
Asbestos Products in Power Plants
A single large power plant built before 1980 could contain hundreds of tons of asbestos-containing materials. Power plant operators used the material in nearly every system, from the moment fuel combustion began to the point where electricity left the building.
Common Asbestos Products
- Asbestos rope and cloth: Used to seal hot piping connections and as protective coverings where workers handled or worked near heated equipment.
- Boiler insulation: Block, blanket and pipe lagging wrapped boiler walls, steam headers and supply lines. Workers who replaced worn sections disturbed the material directly.
- Electrical insulation: Arc chutes, switchgear panels, transformer components and wire wrap in older systems often relied on asbestos for fire resistance.
- Fireproofing spray: Applied to structural steel, boiler casings and ductwork during construction and renovation.
- Floor and ceiling materials: Control rooms commonly used transite panels, vinyl-asbestos tile and asbestos-containing ceiling tile.
- Gaskets and packing: Manufacturers routinely made valve stem packing, pump seals and manhole covers with asbestos sheet material and braided rope. Changing them out released fibers directly into the worker’s breathing zone.
- Insulating cement and mud: Workers mixed these materials dry from bags and hand-applied them to pipe and equipment surfaces. The mixing step was among the most fiber-intensive tasks in the plant.
- Refractory cement and firebrick: Power plants included combustion chambers lined with asbestos-bearing brick and cement. Grinding or cutting these materials generated heavy dust.
- Turbine insulation: Asbestos lagging covered turbine casings, high-pressure and low-pressure sections and exhaust hoods throughout most of the 20th century.
Asbestos content in these products varied widely by type and manufacturer. Some included it in relatively small concentrations, while others composed materials almost entirely of asbestos.
Equipment and Product Manufacturers
Product manufacturers documented in power plant asbestos cases include General Electric and Westinghouse, which made turbines and generators, along with boiler manufacturers Babcock & Wilcox, Combustion Engineering and Foster Wheeler. Johns Manville, Owens Corning and Owens-Illinois produced asbestos-containing insulation, while Garlock, John Crane and Anchor Packing made gaskets and packing.
Several of these companies faced significant asbestos litigation. Some established compensation trusts, while others remain as solvent defendants today. Our attorneys know the exposure history of each.
Power Plant Jobs at Highest Risk
Any blue-collar role inside a power plant before the mid-1980s involved asbestos exposure. But the trades that worked hands-on with insulation, equipment and steam systems faced the highest concentrations, often in enclosed spaces with little ventilation.
Highest-Risk Power Plant Jobs
- Boilermakers, boiler operators and boiler tenders: Workers removed and replaced insulation, mixed refractory cement and accessed internal boiler components, putting them in direct, repeated contact with asbestos materials. During annual maintenance shutdowns, this work could go on for days or weeks at a time.
- Construction and demolition workers: These workers were present from original construction through later retrofits and, eventually, decommissioning.
- Electricians: Panel boards, arc chutes, wire wrap and transformer components all provided regular contact with asbestos-containing materials throughout older electrical systems.
- Insulators (laggers): No trade handled more asbestos, more often. Applying and stripping asbestos blocks, blankets and spray insulation was the entire job.
- Maintenance and repair crews: Swapping out gaskets, packing and worn insulation was routine work with a high fiber-release risk every time.
- Millwrights and mechanics: Turbine, pump and generator work meant constant proximity to asbestos-insulated equipment during installation and repair.
- Pipefitters and steamfitters: Miles of steam piping ran through every plant, all of it lagged with asbestos. Fitting, cutting and pulling out old insulation to reach the pipe beneath was a constant part of the job.
- Plant operators and stationary engineers: Daily rounds through turbine halls and boiler rooms meant ongoing exposure, even without touching materials directly.
- Welders: They often worked directly alongside insulators, breathing fibers disturbed by work happening a few feet away.
Supervisors, inspectors and office staff who moved through these areas regularly also received exposure, even without hands-on work. Outside contractors brought in for specific projects, including insulators, scaffolders and abatement crews, worked alongside permanent plant staff and faced the same asbestos risks.

Diseases Linked to Power Plant Asbestos Exposure
When people inhale asbestos fibers, they can embed in the tissue lining the lungs, abdomen or other organs. Over decades, those embedded fibers cause chronic inflammation, scarring and, in many cases, cancer.
Asbestos-Related Diseases
- Asbestosis: A progressive, non-cancerous scarring of lung tissue. It causes shortness of breath, a chronic cough and reduced lung function that does not resolve. There is no cure.
- Lung cancer: Asbestos exposure raises the risk of lung cancer independent of smoking. When combined with a history of smoking, the risk increases substantially. Published research in Occupational Medicine has documented elevated lung cancer rates among industrial workers with significant asbestos histories.
- Peritoneal mesothelioma: Cancer of the abdominal lining. It’s less common than pleural mesothelioma, but still documented in workers who sustained heavy, prolonged asbestos contact throughout their careers.
- Pleural mesothelioma: Cancer of the tissue surrounding the lungs. It’s the most common asbestos-related cancer among power plant workers and typically takes 20 to 50 years to develop after initial exposure.
- Pleural plaques and pleural thickening: These are non-cancerous changes to the lung lining. They’re well-established markers of past asbestos exposure and indicators of elevated risk for more serious disease down the line.
For people facing mesothelioma today, a diagnosis is not given until 30 or 40 years after leaving a power plant. Many receive a diagnoses after not having contact with asbestos for years. Nemeroff Law will pursue claims of asbestos exposure from years ago.
Power Plant Workers and Secondary Asbestos Exposure
When the workday at the power plant ended, the asbestos fibers followed workers home. They clung to uniforms, settled into the fabric of car seats and shook loose when a spouse pulled work clothes from a hamper or a child ran to hug a parent at the door. Nobody in the household knew they were receiving asbestos exposure.
A 1978 study published in The Lancet found that being married to or living with an asbestos-exposed worker was the single greatest non-occupational risk factor for developing mesothelioma. Decades of research since have confirmed that finding. A 2020 Duke University study published in the American Journal of Surgical Pathology reviewed hundreds of female mesothelioma cases and found that a majority received exposure through a household contact rather than any workplace of their own.
U.S. courts recognize these cases, and Nemeroff Law represents family members in secondary exposure claims. If someone you loved worked at a power plant and you’re now facing a mesothelioma diagnosis, that history matters, and we can help you use it.

Legal Options for Power Plant Workers and Families
A mesothelioma diagnosis opens more than one door to compensation, and many people facing this disease pursue several avenues at the same time. An experienced attorney can identify which options apply to your case and file them in parallel.
Compensation Paths Available
- Asbestos trust fund claims: More than 60 asbestos companies have filed for bankruptcy and established compensation trusts. According to RAND Corporation data, the median scheduled value for a mesothelioma claim is $180,000 per trust, and a single worker with broad exposure history often qualifies to file with multiple trusts at once.
- Personal injury lawsuits: Most asbestos cases target the manufacturers of the insulation, gaskets, turbines and other equipment used at the plant, not the power plant or utility itself. Many of those manufacturers are still operating and financially solvent, meaning an asbestos lawsuit is often the right move rather than a trust fund claim.
- VA benefits: Power plant workers who also served in the military, particularly in the Navy, may qualify for VA disability compensation and health care through the veterans’ program.
- Workers’ compensation: Workers’ comp is a limited option in most mesothelioma cases because of the long gap between exposure and diagnosis. Attorneys sometimes pursue it alongside a lawsuit, not instead of one.
- Wrongful death claims: When a power plant worker has already passed away from an asbestos-related disease, surviving family members can pursue compensation on their behalf through a wrongful death claim.
When mesothelioma cases go to trial, the 2024 Mealey’s Litigation Report puts the average verdict at $20.7 million. Nationally, settlements tend to range between $1 million and $1.4 million. Those are national averages, not guarantees, and every case is different. Statutes of limitations vary by state, but the clock typically starts on the date of diagnosis, not when the exposure originally happened. Waiting is rarely to anyone’s advantage. The sooner you speak with a mesothelioma attorney, the more options remain available to you.

Frequently Asked Questions
Yes. Power plants used asbestos heavily from the 1930s through the early 1980s on boilers, turbines, pipes, gaskets and electrical components. Workers in hands-on trades (i.e., boilermakers, pipefitters, insulators, electricians, mechanics) had some of the highest occupational asbestos exposures in American industry. Published research finds that industrial workers are about four times more likely to develop pleural mesothelioma than the general population.
Boilermakers, pipefitters, insulators, electricians, welders, millwrights, plant operators and maintenance workers all faced heavy exposure. Anyone who cut, scraped, mixed or removed insulation, gaskets, refractory cement or pipe lagging worked directly with friable asbestos. Even office staff, supervisors and inspectors who passed through boiler rooms and turbine halls inhaled airborne fibers. Contractors who came in for specific projects (i.e., insulators, scaffolders, abatement crews) also received exposure.
Mesothelioma typically appears 20 to 60 years after the asbestos exposure that caused it. That long latency is why power plant workers who retired in the 1990s, or even earlier, are still receiving diagnoses today. If you worked at a power plant in the 1960s, 1970s, or 1980s, you’re still within the at-risk window.
Yes. Asbestos fibers traveled home in workers’ vehicles and on their clothing, hair and skin. Spouses who laundered work clothes and children who hugged a parent at the door received exposure to those fibers. Researchers documented this risk as early as 1978. Family members who later developed mesothelioma have legal claims, and Nemeroff Law represents secondary-exposure cases regularly.
Yes, in most cases. Most asbestos lawsuits target the manufacturers of the insulation, gaskets, turbines and other equipment used in the plant, not the plant or utility itself. Many of those manufacturers are still in business, and dozens of others have set up asbestos trust funds that continue paying claims. Our investigators can reconstruct your exposure history even when the original plant is no longer operational.
Statutes of limitations vary by state, but the clock typically starts at the date of diagnosis, not the date of exposure. Most states allow one to three years to file, and wrongful-death claims have separate deadlines. Because the timeline is tight, people facing mesothelioma should consult an attorney as soon after diagnosis as possible. Nemeroff Law offers free, no-obligation case reviews and works on contingency.
