Asbestos-Containing Materials at Ohio Refractory Manufacturing Facilities

Why Asbestos Was Used in Refractory Operations

Refractory manufacturing and minerals processing require materials engineered to withstand extreme heat — often exceeding 1,000°C (1,832°F). Manufacturers incorporated asbestos-containing materials throughout these operations:

Thermal insulation — asbestos-containing insulation products from Johns-Manville and Owens-Illinois allegedly lined kilns, furnaces, pipes, and equipment at Ohio refractory facilities
Refractory product composition — asbestos fibers were allegedly blended into cements, castables, mortars, and plastic refractories manufactured at these Ohio locations and supplied to steel mills and glass manufacturers
Gaskets and sealing materials — asbestos-containing gaskets from Garlock Sealing Technologies and other manufacturers were reportedly used to maintain integrity under heat and pressure
Pipe and boiler insulation — Kaylo pipe insulation (manufactured by Owens-Illinois) and asbestos-containing block insulation products were reportedly standard throughout Ohio industrial facilities
Facility construction — asbestos-containing building materials including Gold Bond and Sheetrock brand products, PABCO roofing shingles, and similar products were allegedly used in floors, ceilings, roof systems, and wall panels
Protective equipment — asbestos-containing gloves, aprons, and welding blankets from Armstrong World Industries were themselves alleged sources of exposure for workers

Specific Asbestos-Containing Products Allegedly Present

Workers at National Refractories & Minerals facilities in Ohio may have been exposed to asbestos-containing materials from:

Johns-Manville — insulation products, refractory materials, and asbestos-cement products

Company History and Ohio Operations

National Refractories & Minerals Corporation

National Refractories & Minerals was a major American producer of refractory products used to line furnaces, kilns, ovens, reactors, and other high-temperature industrial equipment. Ohio was a critical market given the state’s dominant position in steel, rubber, and glass manufacturing through the mid-to-late 20th century. The company reportedly supplied Ohio industries including:

Steel production — Cleveland-Cliffs Steel, Republic Steel Youngstown, U.S. Steel facilities throughout the Mahoning Valley and Lake Erie industrial corridor
Rubber and chemical manufacturing — Goodyear Tire & Rubber Company (Akron) and B.F. Goodrich (Akron)
Automotive assembly — Ford Motor Company’s Lorain Assembly Plant
Glass manufacturing — Ohio’s glass industry concentrated in Toledo and northwest Ohio
Cement production — Ohio cement manufacturers using refractory-lined rotary kilns
Power generation — regional coal-fired and oil-fired power plants

Ohio Facility Locations and Exposure Records

National Refractories & Minerals reportedly maintained operational presence in Ohio through:

Manufacturing and processing facilities where raw refractory materials were processed, mixed, shaped, and fired — operations during which workers may have been exposed to asbestos-containing materials
Supply and distribution operations staging asbestos-containing refractory products for shipment to Ohio industrial customers
On-site installation and maintenance services at customer facilities including steel mills in Youngstown and Cleveland, rubber plants in Akron, and automotive facilities in Lorain — where workers may have been exposed during installation, maintenance, and demolition of refractory linings

Ohio EPA NESHAP (National Emission Standards for Hazardous Air Pollutants) asbestos notification records and demolition/renovation abatement filings associated with operations in Ohio document the alleged presence of asbestos-containing materials at various site locations (per NESHAP abatement records). These records reflect asbestos abatement activities conducted under federal and Ohio state regulations and are maintained by the Ohio EPA Division of Air Pollution Control, accessible through public records requests.

Corporate Timeline: Asbestos Trust Funds and Your Rights

The company operated during periods — particularly the mid-20th century through the 1980s — when asbestos-containing materials were in widespread use and the health risks were known or reasonably knowable to manufacturers and employers
Corporate acquisitions, mergers, divestitures, and bankruptcy proceedings may have established asbestos trust fund Ohio resources that compensate former workers and their families
Successor corporations and insurance carriers may bear legal responsibility for predecessor operations and alleged asbestos exposure
Ohio workers and families may file claims with multiple asbestos bankruptcy trusts simultaneously with civil litigation — Ohio does not prohibit concurrent filings, and experienced attorneys routinely pursue both avenues to maximize recovery

⚠️ ASBESTOS TRUST FUNDS AND OHIO STATUTE OF LIMITATIONS Most asbestos bankruptcy trust funds do not impose strict filing deadlines — but trust assets are finite and depleting. More critically, Ohio’s two-year statute of limitations under Ohio Rev. Code § 2305.10 runs from your diagnosis date. Missing this deadline permanently eliminates your right to file a civil lawsuit in Ohio. Contact an asbestos attorney Ohio today to pursue trust fund claims and civil litigation simultaneously — before either option closes.

Which Ohio Workers and Trades May Have Been Exposed

Asbestos exposure was not limited to a single job classification. Multiple trades may have been exposed through primary work tasks and bystander exposure from adjacent operations. Ohio union members — including those represented by Asbestos Workers Local 3 (Cleveland), Boilermakers Local 900, and USW Local 1307 (Lorain) — may have worked at or alongside these operations. Workers represented by Heat and Frost Insulators locals and Plumbers and Pipefitters UA locals serving Cleveland, Akron, Youngstown, and Columbus may also have encountered asbestos-containing materials at these facilities and at customer sites throughout Ohio.

Insulators (Heat and Frost Insulators)

Insulators faced some of the highest asbestos exposure levels of any trade. At Ohio facilities and customer sites where products were installed, insulators — including members of Asbestos Workers Local 3 (Cleveland) — allegedly:

Mixed and applied asbestos-containing insulating cements by hand in enclosed Ohio industrial facilities
Cut asbestos-containing pipe insulation — including Kaylo brand products from Toledo-based Owens-Illinois — generating heavy concentrations of respirable fiber
Removed old or damaged asbestos-containing insulation during maintenance shutdowns and equipment overhauls at Ohio steel mills and manufacturing plants
Installed asbestos-containing blankets and lagging on high-temperature kilns and furnaces
Applied spray-on asbestos-containing fireproofing products — including Monokote and similar brands — to structural elements and equipment

Pipefitters, Steamfitters, and Boilermakers

Pipefitters, steamfitters, and boilermakers at Ohio refractory facilities worked extensively with process piping, steam systems, and industrial boilers — virtually all historically insulated with asbestos-containing materials. Members of Boilermakers Local 900 and affiliated Plumbers and Pipefitters UA locals serving northeast Ohio may have worked at these facilities or at Ohio industrial customer sites. Their work may have involved:

Installing, removing, and replacing asbestos-containing pipe insulation and fitting covers at Ohio manufacturing facilities
Cutting through asbestos-containing insulation to access pipe flanges and fittings for repair and maintenance
Working in close proximity to insulators applying asbestos-containing products — a well-documented source of bystander exposure at Ohio plant sites
Handling asbestos-containing gaskets from Garlock Sealing Technologies and other manufacturers when breaking and remaking flanges and connections
Repairing and relining boilers and industrial furnaces at Ohio steel, rubber, and glass manufacturing facilities, where equipment allegedly contained asbestos-containing materials

Refractory Manufacturing Production Workers

Production workers directly involved in mixing, forming, and firing refractory products at Ohio facilities may have been exposed to asbestos fibers through:

Kiln and furnace operation — equipment that may have been lined with asbestos-containing materials or insulated with products from Eagle-Picher (Cincinnati), Johns-Manville, and other suppliers
Mixing and casting operations — workers allegedly mixed asbestos-containing refractory compounds and castables in Ohio production areas
Finishing operations — grinding, cutting, and shaping refractory products generated dust that may have contained asbestos fibers in plant environments
Maintenance and repair — workers allegedly removed and replaced asbestos-containing insulation and refractory linings during equipment overhauls

Steelworkers and Industrial Workers at Ohio Customer Sites

Members of USW Local 1307 (Lorain) and other United Steelworkers locals throughout Ohio — including those representing workers at Republic Steel Youngstown, Cleveland-Cliffs Steel, and Ford Lorain Assembly — may have been exposed to asbestos-containing refractory materials during:

Equipment operation and maintenance — asbestos-containing refractory linings in blast furnaces, basic oxygen furnaces, and associated equipment allegedly degraded through thermal cycling and mechanical wear, releasing asbestos fibers into work areas
Furnace rebuild operations — removing old asbestos-containing refractory bricks, castables, and insulation and installing new products from National Refractories & Minerals and competitors
Facility-wide maintenance — asbestos-containing insulation and building materials allegedly present throughout Ohio steel mill, rubber plant, and automotive facility environments exposed workers to respirable fibers
Adjacent trades exposure — steelworkers present while insulators, pipefitters, and refractory specialists worked with asbestos-containing materials at Ohio industrial facilities were at risk of bystander exposure
