Facility Background: North Star Steel / North Star BlueScope Steel Delta, Ohio

Location, Operational History, and Timeline

The steel manufacturing facility in Delta, Ohio (Fulton County, northwestern Ohio) operated under multiple corporate identities:

1969–1970s: Established as an electric arc furnace (EAF) mini-mill by North Star Steel Company
1980s–1990s: Acquired by Cargill, Inc., which held North Star Steel as a subsidiary
1996–2004: Joint venture between North Star Steel and BlueScope Steel (Australian flat-rolled steel producer), creating North Star BlueScope Steel Ltd.
1990s–Present: Continued flat-rolled steel production for automotive, construction, and industrial markets

Plant Operations and Asbestos-Intensive Equipment

The Delta facility operated as an electric arc furnace mini-mill encompassing multiple departments and equipment systems:

Electric arc furnace operations reaching temperatures exceeding 2,900°F
Ladle metallurgy stations
Continuous casting equipment
Hot rolling mills
Heat-treatment and finishing processes
Large-scale boiler and steam systems
Extensive piping, insulation, and mechanical infrastructure
Electrical systems and high-voltage equipment
Structural steel throughout plant buildings

All of these operational areas reportedly involved asbestos-containing materials during much of the facility’s operational history, creating persistent exposure hazards across multiple trades.

Why Steel Plants Were Asbestos-Intensive Industrial Facilities

The Role of Asbestos Products in Steel Manufacturing

Steel production is one of America’s most heat-intensive industrial processes. Electric arc furnaces routinely operate at temperatures exceeding 2,900°F (1,593°C). From the 1930s through the late 1980s — and in some cases beyond, as legacy materials persisted in place — asbestos-containing materials were the industry standard. Major manufacturers marketed asbestos as essential for managing extreme heat because of its thermal resistance, fire resistance, and insulating properties.

Asbestos-containing products reportedly used extensively in steel plant environments included:

Thermal insulation on pipes, boilers, tanks, and vessels (Kaylo, Thermobestos, Aircell brands)
Refractory lining materials in furnaces, ladles, and high-temperature vessels
Gaskets and packing materials sealing flanges, valves, and pumps
Electrical insulation in switchgear, panels, and wiring
Floor tiles, ceiling tiles, and building insulation (Gold Bond, Sheetrock brands)
Protective clothing and welding blankets used near heat sources
Spray-applied fireproofing on structural steel (Monokote products)
Brake linings and friction materials in cranes and hoists
Roofing and siding materials on plant structures (Pabco brands)

Major Asbestos Manufacturers Supplying the Steel Industry

The steel industry was among the largest purchasers of asbestos-containing products in the United States. Manufacturers that allegedly marketed these products to steel plants and industrial facilities included:

Johns-Manville — supplied pipe insulation, block insulation, gaskets, and refractory materials
Owens-Illinois — manufactured asbestos-containing pipe insulation and thermal products
Owens Corning — produced asbestos-containing high-temperature insulation products
W.R. Grace — supplied asbestos-containing refractory materials and industrial insulation
Armstrong World Industries — marketed asbestos-containing floor tiles, ceiling materials, and insulation
Combustion Engineering — provided asbestos-containing boiler components and refractory materials
Garlock Sealing Technologies — manufactured asbestos-containing gaskets and packing materials
Georgia-Pacific — produced asbestos-containing building materials and insulation
Crane Co. — supplied asbestos-containing valves, fittings, and industrial components

These companies knew — or had reason to know — that their products released respirable asbestos fibers during routine installation, maintenance, and removal. Internal documents produced in litigation have demonstrated that knowledge for decades.

Asbestos Exposure in Steel Plant Occupations: High-Risk Trades

Workers in specific trades at facilities like North Star BlueScope Delta faced documented high risks of asbestos-containing material exposure. If you held one of these jobs — even for a single project or turnaround — speak with an attorney before concluding you have no claim.

Insulators (Heat and Frost Insulators Local 1)

Insulators rank among the occupations with the highest rates of asbestos-related disease in published epidemiological literature. Members of Heat and Frost Insulators Local 1 performing work at steel facilities may have been exposed to asbestos-containing materials on a daily basis.

Insulators may have been exposed while:

Installing and removing pipe insulation — including Kaylo and Thermobestos products — on steam lines, hot process lines, and cooling water systems
Wrapping and lagging boilers, tanks, and vessels with asbestos-containing insulation
Applying asbestos-containing cement and mastic products around pipe fittings and flanges
Removing deteriorated insulation during maintenance and replacement operations

Cutting, fitting, and applying this insulation generated heavy concentrations of airborne asbestos dust. For insulators who worked without respirators — which was standard practice before the 1970s — cumulative fiber doses could be substantial.

Pipefitters and Steamfitters (Plumbers and Pipefitters UA Local 562)

Pipefitters and steamfitters may have been exposed during:

Cutting into asbestos-insulated pipes during maintenance and repair
Replacing asbestos-containing gaskets and packing in valves, flanges, and pumps
Working alongside insulators simultaneously removing or applying asbestos-containing insulation
Handling asbestos-containing valve packing and rope products used to seal high-temperature connections

Gasket and packing replacement was not extraordinary work — it was routine. Each removal operation released respirable asbestos fibers into the breathing zone of whoever held the wrench.

Boilermakers

Boilermakers may have been exposed during:

Maintenance and repair of boilers and pressure vessels throughout the facility
Removal and replacement of asbestos-containing boiler insulation — including block insulation, blankets, and lagging
Work inside boilers and vessels during periodic inspections and turnarounds, where disturbed insulation had nowhere to dissipate
Installation and maintenance of boiler components surrounded by asbestos-containing insulation
Replacement of asbestos-containing boiler fittings and components allegedly supplied by Crane Co.

Refractory Workers and Furnace Specialists

Refractory workers may have been exposed through:

Handling asbestos-containing refractory materials and castable refractories allegedly supplied by Combustion Engineering and W.R. Grace
Removing and replacing deteriorated refractory materials during furnace rebuilds
Patching and maintaining furnace linings with asbestos-containing refractory cements
Dust generated during furnace rebuilding operations — work that frequently occurred in enclosed, poorly ventilated spaces

Ironworkers and Structural Steel Workers

Ironworkers may have been exposed during:

Installation and maintenance of spray-applied fireproofing reportedly containing asbestos fibers (Monokote products)
Working in areas where fireproofing was being applied or disturbed
Proximity to asbestos-containing thermal protection materials on structural members

Millwrights and Maintenance Mechanics

Millwrights and maintenance workers may have been exposed while:

Performing general mechanical maintenance requiring work with or around asbestos-containing insulation, including Kaylo and Thermobestos products
Replacing asbestos-containing gaskets and packing on mechanical equipment
Working on machinery containing asbestos-containing components in confined maintenance spaces

Asbestos-Containing Materials at North Star Steel Delta: Construction Through Operations

Initial Construction and Commissioning (Late 1960s–1970s)

When the Delta facility was constructed and commissioned, asbestos-containing materials were the industry standard for thermal insulation, fireproofing, and high-temperature applications. Construction workers — including ironworkers, insulators, pipefitters, boilermakers, electricians, and carpenters — may have been exposed to asbestos-containing materials during this phase.

Asbestos-containing materials reportedly installed during construction included:

Pipe insulation containing chrysotile and/or amosite asbestos (Kaylo and Thermobestos brands, allegedly manufactured by Johns-Manville and Owens-Illinois)
Boiler block insulation and lagging
Refractory cements and castable refractories for furnace linings (allegedly supplied by Combustion Engineering and W.R. Grace)
Spray-applied fireproofing on structural steel (Monokote products)
Floor tiles and adhesives reportedly containing asbestos (Gold Bond brand, Armstrong World Industries)
Electrical insulation containing asbestos
Gaskets and valve packing materials (allegedly supplied by Garlock Sealing Technologies)

Ongoing Operations and Maintenance (1970s–1990s)

As EPA and OSHA regulations began restricting new asbestos use in the 1970s, previously installed asbestos-containing materials reportedly remained in place throughout the facility. Those legacy materials continued to pose exposure risks during:

Deterioration and friability: Asbestos-containing insulation becomes increasingly friable with age — crumbling and releasing airborne fibers without any disturbance at all
Maintenance shutdowns and turnarounds: Periodic shutdowns required workers to handle deteriorated asbestos-containing insulation, often in confined spaces with inadequate respiratory protection
Furnace rebuilds and refractory work: Periodic relining of furnaces, ladles, and vessels required removing and replacing refractory materials that may have contained asbestos
Continued product use: Some asbestos-containing products — including gaskets allegedly manufactured by Garlock Sealing Technologies and certain refractory materials allegedly supplied by Combustion Engineering and W.R. Grace — were reportedly still supplied to industrial facilities into the 1980s during a gradual phase-out

Asbestos Abatement and Later Operations (1990s–Present)

As regulations tightened, the Delta facility faced requirements to identify, manage, and abate asbestos-containing materials. Workers involved in abatement operations — and contractors hired for removal work — may have been exposed to asbestos-containing materials during removal activities if proper containment and respiratory protection protocols were not consistently followed. Abatement work, done improperly, can generate fiber concentrations that rival original installation.

Mesothelioma

Mesothelioma is a rare, aggressive cancer of the thin membrane surrounding the lungs (pleural mesothelioma) or abdominal organs (peritoneal mesothelioma). It develops following inhalation or ingestion of asbestos fibers, which lodge in tissue and trigger chronic inflammation and malignant transformation over decades.

Key facts about mesothelioma:

Latency period: 20–50+ years from initial exposure to diagnosis
Prognosis: Historically poor, with median survival of 12–21 months following diagnosis, though newer multimodal treatments are extending outcomes for some patients
