About National Refractories & Minerals Various Ohio
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 in Akron and B.F. Goodrich in 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), and power generation (regional coal-fired and oil-fired power plants).
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; and 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.
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, including thermal insulation lining kilns, furnaces, pipes, and equipment at Ohio refractory facilities; asbestos fibers blended into cements, castables, mortars, and plastic refractories manufactured at these Ohio locations and supplied to steel mills and glass manufacturers; asbestos-containing gaskets maintaining integrity under heat and pressure; calcium silicate pipe insulation and asbestos-containing block insulation products used as standard throughout Ohio industrial facilities; asbestos-containing building materials including Gold Bond and other brand products, PABCO roofing shingles, and similar products used in floors, ceilings, roof systems, and wall panels; and asbestos-containing gloves, aprons, and welding blankets serving as sources of exposure for workers.
General Equipment at National Refractories & Minerals Various Ohio
The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.
Documented Asbestos Evidence — Ohio
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Ohio Environmental Protection Agency (Ohio EPA) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.

Who May Have Been Exposed at National Refractories & Minerals Various Ohio
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 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 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; and applied spray-on asbestos-containing fireproofing products to structural elements and equipment.
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; handling asbestos-containing gaskets when breaking and remaking flanges and connections; and repairing and relining boilers and industrial furnaces at Ohio steel, rubber, and glass manufacturing facilities.
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, mixing and casting operations where workers allegedly mixed asbestos-containing refractory compounds and castables, finishing operations involving grinding, cutting, and shaping refractory products that generated dust containing asbestos fibers, and maintenance and repair work removing and replacing asbestos-containing insulation and refractory linings during equipment overhauls. Members of USW Local 1307 (Lorain) and other United Steelworkers locals throughout Ohio may have been exposed to asbestos-containing refractory materials during equipment operation and maintenance as asbestos-containing refractory linings degraded through thermal cycling, furnace rebuild operations removing and installing refractory products, facility-wide maintenance involving asbestos-containing insulation and building materials, and adjacent trades exposure as steelworkers were present while insulators, pipefitters, and refractory specialists worked with asbestos-containing materials.
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 compensation 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.
