⚠️ CRITICAL OHIO FILING DEADLINE WARNING

Ohio law gives mesothelioma and asbestos disease victims only TWO YEARS to file a lawsuit — and that clock starts running from the date of your diagnosis, not the date of your exposure.

Under Ohio Rev. Code § 2305.10, if you or a family member has been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer and miss this two-year window, you may permanently lose your right to compensation — no matter how clear-cut your case is.

Do not wait for symptoms to worsen. Consult a qualified mesothelioma lawyer in Ohio today.

Asbestos bankruptcy trust fund claims can be filed simultaneously with your Ohio civil lawsuit, and trust fund assets are finite — they deplete as claims are paid. Every day you delay is a day closer to losing compensation you may be legally entitled to receive.


If you or a family member worked at Ohio Edison’s Mansfield Generating Station and has since been diagnosed with mesothelioma, asbestosis, or lung cancer, you may have legal rights under Ohio law. For decades, workers at this coal-fired power plant in Mansfield, Ohio may have been exposed to asbestos-containing materials installed and maintained throughout the facility. Manufacturers — including Johns-Manville Corporation, Owens-Illinois, Combustion Engineering, and Garlock Sealing Technologies — and facility operators allegedly knew about the health hazards of asbestos long before workers received adequate warnings.

Ohio Mesothelioma Settlement Options

Ohio imposes a two-year statute of limitations under Ohio Rev. Code § 2305.10, measured from the date of diagnosis or the date the worker reasonably discovered the connection between their illness and occupational asbestos exposure. This deadline is absolute — courts will not grant extensions because you were unaware of it or because your condition is worsening.

Ohio residents may file simultaneously against multiple asbestos bankruptcy trust funds while pursuing a civil lawsuit in state court — a significant financial advantage that a qualified asbestos attorney can help you exercise. An experienced Ohio mesothelioma lawyer understands both the state civil litigation process and the federal trust fund claim procedures, giving you the best opportunity to maximize total recovery. Do not wait another day.


What Was the Mansfield Generating Station?

Facility Overview and History

The Mansfield Generating Station, operated by Ohio Edison Company — a FirstEnergy Corporation subsidiary — served as a major coal-fired steam electric generating facility in Richland County, northern Ohio, for decades. Ohio Edison’s service territory spans much of northeastern and north-central Ohio, overlapping with communities that supplied workers to major industrial employers including Cleveland-Cliffs Steel, Republic Steel in Youngstown, Goodyear and B.F. Goodrich in Akron, and Ford’s Lorain Assembly Plant. Many workers cycled among these industrial sites over careers spanning multiple decades, potentially accumulating asbestos exposures at more than one Ohio facility.

Like virtually all large-scale coal-fired steam electric plants built in the mid-twentieth century, the Mansfield Generating Station was constructed during an era when asbestos-containing materials were the industry standard. From the 1940s through the late 1980s, asbestos-containing materials were reportedly installed throughout the facility in the following applications:

  • Wrapping high-temperature steam lines with asbestos-containing pipe covering
  • Encasing boilers and fireboxes with asbestos-containing refractory materials
  • Insulating turbines and generators with asbestos-containing block insulation
  • Sealing joints and flanges with asbestos-containing gaskets and packing throughout the facility
  • Lining refractory sections of the main steam boiler with asbestos-containing materials

The utility power generation industry was one of the largest consumers of asbestos-containing insulation products in twentieth-century America. Documents produced in Ohio and national asbestos litigation show that manufacturers including Johns-Manville Corporation, Owens-Illinois, and Combustion Engineering allegedly knew about the health hazards of asbestos long before they warned the workers installing and maintaining their products.

Why Asbestos-Containing Materials Were Standard at Coal-Fired Power Plants

Coal-fired steam generating stations operate under extreme heat and pressure. Burning coal heats water, produces steam, drives turbines, and generates electricity. That process requires pipes, boilers, turbines, and auxiliary equipment to be insulated against heat loss and protected against fire.

Asbestos-containing materials were the engineering solution of choice because they:

  • Withstand temperatures far exceeding those of other natural insulating materials
  • Resist fire and chemical degradation
  • Form into pipe covering, block insulation, blankets, rope packing, and gaskets
  • Were inexpensive and widely available during the postwar construction boom

The same fibrous mineral structure that gave asbestos its heat-resistant properties makes it extraordinarily dangerous when inhaled. Asbestos fibers lodged in lung tissue or the mesothelium cannot be expelled by the body and may trigger malignant transformation decades after initial exposure. Workers in Ohio’s industrial corridor — stretching from Cleveland through Akron, Mansfield, and Youngstown — faced some of the heaviest cumulative asbestos exposures in the nation, a direct consequence of the dense concentration of coal-fired power, steel, rubber, and automotive manufacturing across the region.


When Asbestos-Containing Materials Were Present

Original Construction and Installation (1940s–1960s)

Original construction of the Mansfield Generating Station reportedly involved the widespread installation of asbestos-containing materials, including:

  • Asbestos-containing pipe covering and block insulation allegedly manufactured by Johns-Manville Corporation and Owens-Illinois
  • Boiler insulation and refractory materials allegedly supplied by Combustion Engineering
  • Turbine and generator lagging reportedly containing asbestos fibers
  • Gaskets, packing, and sealing materials allegedly manufactured by Garlock Sealing Technologies and Eagle-Picher

Engineers specified these products, and trades workers — particularly members of Asbestos Workers Local 3 (Cleveland) and related Ohio union locals — installed them, often with no knowledge of the health hazards involved. Union contractors that serviced Ohio Edison facilities during this era routinely dispatched members of Boilermakers Local 900 and USW Local 1307 (Lorain) to projects across the northern Ohio region, including Richland County generating stations.

Ongoing Maintenance and Repair Cycles (1960s–1970s)

Steam generating stations require continuous maintenance. Insulation on pipes, valves, boilers, and turbines is disturbed, removed, and replaced during planned outages and emergency repairs. Each disturbance of legacy asbestos-containing insulation — including Johns-Manville pipe covering and Combustion Engineering boiler lagging — had the potential to release airborne asbestos fibers into work areas throughout the plant.

Workers in the vicinity, whether or not they were directly handling the material, may have been exposed. This pattern of bystander and ambient asbestos exposure is well-documented in Ohio asbestos litigation, particularly in Cuyahoga County — Ohio’s most active asbestos litigation venue — and in Franklin County Common Pleas Court in Columbus.

Transition and Abatement Period (Late 1970s–1980s)

Following stricter federal regulation under the Clean Air Act and OSHA’s 1972 asbestos standards, power plant operators began transitioning away from asbestos-containing materials and, in some cases, removing or encapsulating legacy installations. Legacy asbestos-containing materials from manufacturers including Johns-Manville, Owens-Illinois, and Combustion Engineering reportedly remained in place at the Mansfield Generating Station well into this period, continuing to pose potential exposure risk during routine maintenance and renovation work. Ohio utility workers who participated in abatement and renovation activities during this era may have faced some of the highest fiber concentrations of their careers — disturbance of aged, friable asbestos-containing insulation generates particularly heavy airborne releases.


Asbestos-Containing Products Allegedly Present at Mansfield

Pipe Covering and Block Insulation

High-temperature steam pipes running through the boiler house, turbine hall, and auxiliary areas were routinely covered with asbestos-containing pipe insulation.

Johns-Manville Corporation — one of the nation’s largest manufacturers of asbestos-containing products — allegedly supplied products used at utility facilities across Ohio, including installations consistent with those at the Mansfield Generating Station:

  • Asbestos-containing pipe covering (85% magnesia or calcium silicate with asbestos fibers)
  • Asbestos-containing block insulation for boilers and large equipment surfaces
  • Asbestos-containing fitting covers and valve insulation
  • Asbestos-containing insulating cement used to seal joints and repair damaged insulation

Johns-Manville’s product lines were reportedly present at Ohio Edison’s generating stations throughout the northern Ohio region, consistent with documented distribution patterns at comparable Ohio facilities including Cleveland-Cliffs Steel operations and Goodyear’s Akron manufacturing complex.

Owens-Illinois (later Owens Corning), an Ohio-based company headquartered in Toledo, manufactured asbestos-containing insulation products — including block insulation and pipe covering — reportedly distributed and installed at Ohio utility plants during this era. Owens-Illinois products are among those most frequently identified in Ohio asbestos litigation involving utility and industrial facilities.

Steam Boilers and Refractory Materials

The main steam boilers at the Mansfield Generating Station were large structures requiring extensive thermal insulation. Combustion Engineering — a major manufacturer and installer of power plant boilers — allegedly supplied boiler equipment and associated asbestos-containing materials to utility plants across the United States, including facilities in Ohio operated by Ohio Edison and comparable employers.

Boiler-related asbestos-containing materials allegedly present at the Mansfield facility included:

  • Asbestos-containing boiler block and lagging
  • Asbestos-containing refractory and castable materials used in fireboxes
  • Asbestos-containing rope and gasket materials used in boiler doors and access hatches
  • Asbestos-containing cloth and blanket materials used for temporary and permanent insulation

Boilermakers dispatched to the Mansfield Generating Station through Boilermakers Local 900 reportedly performed work in close proximity to these materials throughout the facility’s operational history.

Steam Turbines and Generators

Steam turbines operating under high pressure and temperature were insulated with asbestos-containing materials to improve efficiency and protect workers from burn hazards. Turbine insulation, casing lagging, and associated valve and flange insulation were reportedly manufactured using asbestos-containing materials by Johns-Manville, Owens-Illinois, and other suppliers to the utility industry throughout the mid-twentieth century. Workers dispatched by Ohio union locals to turbine overhaul and maintenance work at the Mansfield facility may have encountered these materials during every planned outage.

Feed Water Heaters and Heat Exchangers

Feed water heaters — components that preheat boiler feed water using extracted steam — were a source of asbestos-containing insulation at the Mansfield Generating Station. These vessels and their associated piping were reportedly insulated with:

  • Johns-Manville asbestos-containing block insulation
  • Owens-Illinois asbestos-containing pipe covering
  • Asbestos-containing gasket and packing materials requiring regular maintenance and periodic replacement

Ohio pipefitters and maintenance workers who opened, repaired, and reinsulated feed water heaters and heat exchangers may have encountered these asbestos-containing materials during every scheduled outage cycle.

Gaskets, Packing, and Miscellaneous Products

Asbestos-containing materials were allegedly present at the Mansfield Generating Station in additional forms:

  • Garlock Sealing Technologies asbestos-containing gaskets — sheet and spiral-wound — used throughout steam and water systems
  • Asbestos-containing valve and pump packing made from braided asbestos fibers
  • Eagle-Picher asbestos-containing insulation products used for flanges, valves, and miscellaneous equipment
  • Asbestos-containing floor tile and ceiling materials in ancillary buildings
  • Asbestos-containing fire doors and fire-rated construction materials
  • Asbestos-containing electrical insulation on wiring and panel components

These product types are consistent with asbestos-containing materials identified at comparable Ohio industrial facilities — including Republic Steel in Youngstown and B.F. Goodrich in Akron — in published trial records and asbestos trust fund claim documentation.
