If you worked at a Milwaukee-area manufacturing facility, power plant, foundry, or heavy equipment plant as a member of United Steelworkers Local 14979—or if you are a family member of someone who did—you may have been exposed to asbestos decades ago without knowing it. Today, you might be experiencing shortness of breath, chest pain, or a persistent cough. Or perhaps you’ve already received a diagnosis of mesothelioma or asbestos-related lung cancer.

This guide explains where that exposure likely occurred, what it means for your legal rights, and what you need to do right now. A qualified mesothelioma lawyer in Wisconsin can help you hold the responsible companies accountable and recover compensation for you and your family.

Urgent Legal Notice: Wisconsin’s statute of limitations for personal injury claims related to asbestos exposure is three years from the date of diagnosis under Wis. Stat. § 893.54. That deadline is not a formality — miss it, and you lose the right to recover anything. If you or a family member has been diagnosed with mesothelioma, asbestos-related lung cancer, or asbestosis, contact a qualified asbestos litigation attorney immediately.

United Steelworkers Local 14979: Milwaukee’s Industrial Union

The Union’s History and Jurisdiction in Milwaukee

The United Steelworkers is the largest industrial union in North America, representing workers across metal production, manufacturing, chemical processing, rubber, paper, and energy industries. Local 14979, based in Milwaukee, has reportedly represented workers employed at manufacturing facilities, metal-working shops, processing plants, and related industrial operations throughout the greater Milwaukee metropolitan area.

Why Milwaukee Workers Faced Persistent Asbestos Exposure

Milwaukee’s industrial base — built on heavy manufacturing, metalworking, foundries, and large-scale production — created conditions for routine asbestos exposure throughout the mid-twentieth century. Asbestos-containing materials insulated equipment, protected structures from fire, and kept high-temperature industrial processes running across the region. USW Local 14979 members worked in environments where asbestos was disturbed, friable, and airborne on a daily basis.

What Work Did These Members Perform?

Members of USW Local 14979 reportedly performed industrial tasks across multiple job classifications, many of which involved direct or incidental contact with asbestos-containing materials.

Production and Line Work

Operating and maintaining blast furnaces, smelting equipment, and rolling mills
Working with molten metals and high-temperature casting processes
Operating presses, stamping machines, and fabrication equipment lined with heat-resistant materials
Monitoring and adjusting furnace operations in areas where insulation materials were present

Quality Control and Supervisory Roles

Supervisors and quality inspectors who regularly walked production floors through areas where asbestos dust was present may have been exposed without directly handling any ACMs
Shift supervisors who conducted rounds through insulation-heavy areas of the plant

Milwaukee County Asbestos Exposure: Where Local 14979 Members Worked

Milwaukee has historically been a major Midwestern industrial hub. USW Local 14979 members allegedly worked at numerous facilities in the Milwaukee area where asbestos-containing materials were reportedly used. The specific product inventories of individual facilities must be established through documentary evidence in litigation.

A.O. Smith Corporation

One of Milwaukee’s largest industrial employers for much of the twentieth century, A.O. Smith operated large manufacturing facilities on the city’s north side. Workers there reportedly maintained boilers, steam lines, and heat-treating equipment that may have been insulated with Johns-Manville pipe covering, Owens-Corning block insulation, and boiler cement and lagging materials allegedly containing asbestos. At its peak, the facility employed tens of thousands of workers — meaning USW-affiliated members may have accumulated multi-decade exposures.

Allis-Chalmers Manufacturing Company

Allis-Chalmers manufactured heavy electrical equipment, turbines, and industrial machinery at major facilities in West Allis, directly adjacent to Milwaukee. Members of the steelworkers’ union who worked at or alongside Allis-Chalmers operations allegedly encountered asbestos-containing insulation on:

Turbines and generators reportedly insulated with Kaylo and Thermobestos products
Switchgear and electrical enclosures containing asbestos arc chutes and insulating boards
Pipe systems throughout the plant reportedly using Johns-Manville and Armstrong thermal insulation
High-temperature equipment with Celotex boiler lagging and block insulation

Allis-Chalmers has been named in substantial asbestos litigation nationally, and records from this facility have reportedly surfaced in discovery proceedings across multiple jurisdictions.

Harnischfeger Industries (P&H Mining Equipment)

Harnischfeger, based in Milwaukee and later West Milwaukee, manufactured cranes, mining equipment, and electric shovels. Workers maintaining and building this heavy equipment reportedly may have been exposed to:

Asbestos-containing gaskets on hydraulic and pneumatic systems, including products from Garlock Sealing Technologies and John Crane
Clutch linings and brake linings allegedly containing asbestos
Insulation materials on electrical and steam components, including Aircell and Monokote spray fireproofing

Milwaukee’s Industrial Corridor — General Foundries and Metal Plants

Milwaukee’s Menomonee Valley and surrounding neighborhoods hosted numerous foundries and metal processing operations. Foundry workers represented by steelworkers unions routinely worked with:

Refractory materials and furnace linings reportedly containing asbestos binders, including Combustion Engineering furnace insulation products
Heat-resistant casting compounds
Insulation materials in foundry ovens and crucibles
Gasket and packing materials from Eagle-Picher and Garlock

(Documented in occupational health surveys of Midwestern foundry operations from the 1960s and 1970s.)

Wisconsin Electric Power Company / We Energies Facilities

USW-represented workers who performed maintenance or contract work at power generation facilities in the Milwaukee area may have been exposed to asbestos-containing lagging on:

Turbines and rotors reportedly insulated with Johns-Manville products
Boilers and steam drums covered with Armstrong World Industries boiler lagging and cement
Steam pipes and heat exchangers reportedly using Kaylo thermal insulation
Valves and flanges sealed with gasket materials from Garlock Sealing Technologies and Armstrong

(Consistent with OSHA inspection records from similar power generation facilities of the era.)

Briggs & Stratton Corporation

Briggs & Stratton operated manufacturing plants in Milwaukee and surrounding communities. Workers in production, maintenance, and facilities management at these plants allegedly encountered:

Asbestos-containing floor tiles and associated black mastic adhesives
Ceiling materials and acoustic panels reportedly containing asbestos
Pipe insulation and boiler covers from Johns-Manville and Owens-Corning
Gasket materials on machinery from Garlock and Armstrong

Note on Facility-Specific Claims: The presence of specific asbestos-containing products at any individual facility is a factual question that must be established through evidence in legal proceedings. A qualified Wisconsin asbestos attorney can identify the documentary evidence specific to your employer and workplace.

Asbestos Exposure in Wisconsin: Common Products and Materials

Based on occupational health literature, industrial surveys, and the known product inventories of Milwaukee-area industrial operations during the mid-twentieth century, members of USW Local 14979 may have been regularly exposed to the following categories of asbestos-containing products.

Thermal Insulation Products

Pipe Covering and Block Insulation

Products from Johns-Manville, Owens-Corning, Celotex, Armstrong World Industries, Georgia-Pacific, and W.R. Grace were widely used on steam pipes and hot-water lines throughout Milwaukee industrial facilities. Trade names included:

Kaylo pipe covering and block insulation
Thermobestos wrap and board products
Aircell spray-applied insulation
Generic asbestos-fiber pipe insulation and rigid block materials

Cutting, fitting, and removing this insulation released airborne chrysotile and amosite asbestos fibers. Installation and replacement were routine maintenance tasks that generated persistent dust exposure.

Boiler Lagging and Boiler Cement

High-temperature boiler insulation from Johns-Manville, Armstrong World Industries, and other manufacturers reportedly contained between 15% and 85% asbestos by weight. Products included:

Block insulation and wrap materials
Boiler cement and lagging compounds
Spray-applied refractory materials

Maintenance workers applied and removed these materials on a regular basis. Direct contact and inhalation during application, repair, and removal created sustained occupational exposure.

Furnace and Oven Insulation

Refractory insulating cements and block products from Combustion Engineering and other manufacturers were reportedly used in kilns, heat-treating ovens, and industrial furnaces throughout Milwaukee. Handling and replacement during maintenance operations exposed workers to disturbed asbestos fibers.

Gaskets, Packing, and Seals

Sheet Gasket Material

Gasket products from Garlock Sealing Technologies, Armstrong World Industries, and other manufacturers were standard throughout Milwaukee industrial pipe systems. Materials included:

Gasket sheets cut to size at the worksite
Spiral-wound and ring gasket assemblies
Compressed fiber sheet material with asbestos binders

Workers who cut gaskets to size released concentrated bursts of asbestos fiber. Replacement on high-pressure applications was a routine maintenance function.

Rope and Woven Packing

Valve stems and pump shafts throughout Milwaukee industrial plants were sealed with braided asbestos packing from manufacturers including:

Armstrong World Industries
Garlock Sealing Technologies
John Crane Company

Workers handled these materials daily during routine maintenance and repair.

Flange Gaskets

Pre-cut asbestos spiral-wound and ring gaskets from Crane Co., Garlock, and Armstrong were used extensively on high-pressure systems. Removal and installation during equipment repair exposed workers to friable fibers.

Friction Materials

Brake Linings and Clutch Facings

Industrial equipment — including cranes, overhead hoists, large presses, and stamping machines — used asbestos-containing brake and clutch components. Workers who serviced this equipment generated asbestos dust during:

Grinding operations on friction surfaces
Drilling and boring through worn components
Replacement and installation of new brake and clutch assemblies

Building and Construction Materials

Asbestos-Cement Board (Transite)

Transite panels from Celotex, Johns-Manville, and Georgia-Pacific were widely used as fire barriers and structural panels in industrial construction from the 1930s through the 1970s. Cutting, drilling, or breaking transite panels released high concentrations of asbestos fibers. Applications included:

Walls and wall panels
Ceilings and drop-ceiling components
Fire barriers and protective enclosures
Structural applications throughout facilities

Spray-Applied Fireproofing

Steel structural beams in Milwaukee industrial buildings were reportedly coated with spray-applied asbestos fireproofing, including:

Monokote and other amosite-based coatings in common use until banned in the mid-1970s
Aircell spray fireproofing
Generic spray-applied asbestos fireproofing compounds
