Why Former Cardinal Workers Are Filing Asbestos Lawsuits Now
Cardinal Power Plant in Brilliant, Ohio, operated as one of the Midwest’s largest coal-fired generating stations for decades. Workers who built, operated, and maintained this facility — insulators from Heat and Frost Insulators Local 1 and Local 27, boilermakers, pipefitters from UA Local 562 and UA Local 268, electricians, millwrights, and maintenance laborers — may have been exposed to asbestos-containing materials throughout the plant’s construction and operational history.
Mesothelioma, asbestosis, and asbestos-related lung cancer typically develop 20 to 50 years after initial exposure. Workers who handled pipe insulation or gaskets at Cardinal in the 1960s and 1970s are receiving diagnoses today — and their families deserve answers.
If you worked at Cardinal Power Plant and have been diagnosed with mesothelioma, asbestosis, or lung cancer, you may hold legal claims against the manufacturers who supplied asbestos-containing materials to the facility. An experienced asbestos cancer lawyer can evaluate your case at no cost.

Cardinal Power Plant: Facility Background
Location and Ownership
Cardinal Power Plant sits along the Ohio River in Brilliant, Ohio, Monroe County — southeastern Ohio’s industrial corridor. American Electric Power (AEP) owns and operates the facility through Ohio Power Company.
Construction Timeline and Scale
Cardinal was built in three phases:
- Unit 1: Commercial operation began 1967
- Unit 2: Commercial operation began 1967–1968
- Unit 3: Commercial operation began 1977
Each unit operates as a pulverized-coal steam turbine generator system. At peak capacity, Cardinal produced approximately 1,880 megawatts. The plant draws cooling water from the Ohio River and has employed hundreds of full-time workers, with additional contract workers during construction and periodic maintenance outages.
Comparable Midwestern facilities built under the same material specifications include Labadie Energy Center (Franklin County, MO), Portage des Sioux Power Plant (St. Charles County, MO), and Rush Island Energy Center (Jefferson County, MO) — all operated by Ameren UE.
Who Worked at Cardinal Power Plant
Direct Employees and Trade Contractors
Cardinal’s workforce has included AEP direct employees and outside contractors across multiple skilled trades. Construction of each unit required:
- Iron workers and structural steel erectors
- Pipefitters and steamfitters (UA Local 562 and UA Local 268)
- Insulators — also called asbestos workers or thermal insulation mechanics — from Heat and Frost Insulators Local 1 and Local 27
- Boilermakers
- Electricians
- Millwrights and machinists
- Laborers and helpers
Maintenance work continued year-round. Annual and biannual outages brought contract workers into the facility to inspect, repair, and replace boilers, turbines, piping systems, heat exchangers, and related equipment. These outage workers may have disturbed previously installed asbestos-containing materials and encountered liberated fibers during that work — often without adequate warning or protection.
Why Asbestos-Containing Materials Were Present at Power Plants Like Cardinal
The Thermal Engineering Problem
Coal-fired power plants manage extreme heat. The process works like this:
- Pulverized coal burns in enormous boilers to generate steam
- Superheated, high-pressure steam travels through miles of piping to turbines
- Turbines spin to generate electricity
- Steam condenses and recirculates
Piping systems, boilers, and turbines operate at 700°F to over 1,000°F. Steam pressures in supercritical units exceed 3,500 pounds per square inch.
Why Manufacturers Chose Asbestos
Asbestos offered properties that cheaper alternatives could not match:
- Does not burn or melt at typical industrial temperatures
- Can be woven into cloth, compressed into boards, or mixed into cement
- Resists steam, condensates, and cleaning chemicals
- Cost less than alternatives and was widely available
- Conforms to irregular surfaces — pipe elbows, valves, and flanges
Before health hazards were acknowledged and regulated, asbestos-containing materials went into virtually every major power plant built in the United States, including those constructed during Cardinal’s three build phases.
When Peak Asbestos Use Occurred
Unit 1 and Unit 2 construction (mid-to-late 1960s): Both units were built at the height of industrial asbestos use. Contractors reportedly specified and installed asbestos-containing insulation, gaskets, packing, and related materials as standard practice.
Unit 3 construction (mid-1970s): OSHA issued asbestos exposure standards beginning in 1972, but asbestos-containing materials remained widely available, specified in contracts, and reportedly installed through this period.
Maintenance and outage work (1960s through 1980s and beyond): Asbestos-containing materials installed during construction remained in place for decades. Workers who disturbed these materials during outages may have been exposed to asbestos fibers long after original construction ended — sometimes without any knowledge that the materials they were cutting, removing, or working adjacent to contained asbestos.
Demolition and abatement work: Workers who later replaced equipment or performed asbestos remediation may also have encountered asbestos-containing materials during these activities.
Where Asbestos-Containing Materials Were Allegedly Present at Cardinal
The locations and products below reflect construction practices, equipment specifications, and materials commonly used at large coal-fired power plants built during the 1960s and 1970s. The same material types have been documented at comparable facilities including the Labadie Energy Center, Portage des Sioux Power Plant, and Rush Island Energy Center. Specific product presence at Cardinal is alleged based on these industry patterns; individual exposure claims require documentation developed through litigation discovery.
Boiler House and Steam Generation Systems
The boiler house is typically the most asbestos-intensive area in a coal-fired power plant. Cardinal’s boilers generated millions of pounds of steam per hour. Workers in this area may have encountered:
Boiler casing and refractory insulation — reportedly containing asbestos-containing materials manufactured by Johns-Manville Corporation, Armstrong World Industries, or W.R. Grace. Workers who installed, repaired, or worked adjacent to boiler casings may have been exposed to asbestos-containing insulating cements and block insulation.
High-temperature pipe insulation — allegedly included asbestos-containing pipe covering manufactured by Johns-Manville, Owens-Illinois, Armstrong World Industries, and Celotex Corporation, along with asbestos-containing calcium silicate insulation and asbestos insulating cement.
Boiler gaskets and door rope seals — reportedly manufactured by Garlock Sealing Technologies and other suppliers using asbestos-containing materials rated for extreme temperatures at boiler access points and expansion joints.
Thermal expansion joints — may have incorporated asbestos-containing flexible fabric sections connecting boiler sections to adjacent structures, allegedly supplied by Johns-Manville or comparable manufacturers.
Turbine and Generator Halls
Workers in the turbine hall may have encountered:
Turbine casing insulation — outer casings were typically insulated with asbestos-containing block insulation and finishing cements during this era. Manufacturers allegedly supplying these materials included Johns-Manville, Armstrong World Industries, and Owens-Illinois.
High-pressure steam piping insulation — piping feeding and exhausting turbines reportedly incorporated multiple layers of asbestos-containing pipe covering applied across miles of pipe. Trade names allegedly present at comparable facilities include Kaylo (Owens-Illinois), Thermobestos, and product lines from Johns-Manville and Armstrong World Industries.
Turbine packing and gaskets — mechanical seals within steam turbines, including valve stem packing and flange gaskets, were frequently manufactured from compressed asbestos fiber sheet or braided asbestos packing by Garlock Sealing Technologies, Crane Co., and other suppliers.
Governor and control valve insulation — these control components were also reportedly insulated with asbestos-containing materials supplied by Johns-Manville and Combustion Engineering.
Piping Systems
A plant the size of Cardinal contains miles of piping carrying steam, feedwater, fuel oil, and other process fluids. Workers throughout these systems may have encountered:
Asbestos pipe covering (also called pipe lagging) — the standard insulation product for high-temperature steam piping throughout this era. Products reportedly used at comparable facilities came from:
- Johns-Manville Corporation (multiple product lines)
- Owens-Illinois (Kaylo brand)
- Armstrong World Industries
- Celotex Corporation
- W.R. Grace (specialty insulation products)
- Georgia-Pacific (building insulation materials)
Asbestos insulating cement — applied over pipe covering at elbows, tees, valves, and flanges. Workers who mixed and applied this cement by hand may have faced higher airborne fiber concentrations than workers in other trades. Products supplied by Johns-Manville, Armstrong World Industries, and W.R. Grace were standard at comparable facilities.
Asbestos-containing block insulation — calcium silicate block with asbestos reinforcement, or solid asbestos block, was allegedly used on larger-diameter pipes, vessels, and ductwork. Manufacturers including Johns-Manville, Armstrong World Industries, and Owens-Illinois supplied these materials under trade names including Kaylo, Thermobestos, and comparable products.
Asbestos rope and tape — used for sealing, wrap applications, and patching of pipe insulation, allegedly supplied by Johns-Manville, Garlock Sealing Technologies, and comparable manufacturers.
Pumps, Valves, and Mechanical Equipment
The facility contains thousands of pumps, valves, and related mechanical components requiring ongoing maintenance. Workers servicing this equipment may have encountered:
Valve packing — braided asbestos fiber packing manufactured by Garlock Sealing Technologies and Crane Co. was standard throughout this era. Valve maintenance workers who pulled and replaced packing materials may have been exposed to asbestos-containing materials during each maintenance cycle.
Pump seals and gaskets — feedwater pumps, condensate pumps, and other process pumps are alleged to have used asbestos-containing shaft seals and flange gaskets throughout this era, supplied by Garlock Sealing Technologies and comparable manufacturers.
Flange gaskets — flanged pipe connections allegedly used compressed asbestos fiber sheet gaskets manufactured by Garlock Sealing Technologies and other suppliers. Pipefitters who cut gaskets to size and installed them may have been exposed during each operation.
Electrical Systems
Electricians at facilities of this type generally had less direct contact with thermal insulation than insulators or pipefitters, but may have encountered:
Electrical panel and switchgear insulation — some panels, bus ducts, and switchgear components manufactured during this era allegedly incorporated asbestos-containing arc-suppression and insulating materials supplied by Armstrong World Industries and comparable manufacturers.
Cable tray and conduit fireproofing — asbestos-containing fireproofing materials were reportedly applied to cable trays, conduits, and structural members at power plants of this era. Products supplied by Johns-Manville and W.R. Grace may have been present at Cardinal.
Asbestos-containing wallboard and ceiling tiles — equipment rooms and control rooms in facilities of this era reportedly used asbestos-containing building materials for fire resistance, supplied by Johns-Manville, Armstrong World Industries, and comparable manufacturers.
