Who This Page Is For

For decades, electricians with IBEW Local 494 in Milwaukee built the electrical infrastructure that powered southeastern Wisconsin’s factories, refineries, power plants, and hospitals. Many are now being diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer—diseases that take 20 to 50 years to develop after exposure.

If you or a family member worked as an IBEW Local 494 electrician and received one of these diagnoses, compensation may be available through Wisconsin mesothelioma settlements and asbestos trust funds. This guide explains where exposures reportedly occurred, which products are implicated, and what steps to take now.

Who IBEW Local 494 Represents

IBEW Local 494 is headquartered in Milwaukee and represents inside wiremen, construction electricians, maintenance electricians, and related classification workers across Milwaukee, Waukesha, Washington, Ozaukee, and Racine counties.

Where Local 494 Members Worked

Local 494 members worked across employment settings that historically contained asbestos-containing materials:

Heavy industrial facilities (steel mills, foundries, manufacturing plants)
Electrical power generating stations and substations
Oil refineries and chemical processing facilities
Commercial construction (high-rise office buildings, hospitals, schools, government buildings)
Municipal utility infrastructure
Pulp and paper mills
Automotive and heavy equipment manufacturing plants

Members may have been exposed to asbestos products manufactured by Johns-Manville, Owens Corning, Eagle-Picher, Garlock Sealing Technologies, Armstrong World Industries, W.R. Grace, Georgia-Pacific, Celotex, Crane Co., and Combustion Engineering. Occupational health researchers have documented that electricians in these environments routinely encountered asbestos as bystanders—even without directly handling insulation or lagging—because airborne fibers travel freely in shared workspaces.

How Electricians Were Exposed to Asbestos

Direct Handling of Asbestos-Containing Electrical Products

Electricians through the mid-twentieth century worked directly with electrical components that contained asbestos:

Arc chutes and arc barriers in switchgear, circuit breakers, and motor control centers — asbestos board and asbestos paper manufactured by General Electric and Westinghouse provided heat resistance
Thermal insulation on wiring and cables — asbestos-containing tape and braided asbestos sleeves manufactured by Essex Wire and Thermal Industries were standard on high-temperature industrial wiring
Asbestos-insulated wire (AIW) — widely used in industrial and commercial settings through the 1970s, manufactured by General Electric, Westinghouse, and Essex Wire
Asbestos cloth and tape — applied as wrapping around junction boxes, conduit penetrations through firewalls, and electrical panels to meet fire code requirements, including products manufactured by Johns-Manville
Electrical panels and distribution boards — manufactured with asbestos-cement backboards by Square D and other manufacturers
Gaskets and packing in electrical conduit systems running through boiler rooms and high-temperature areas, manufactured by Garlock Sealing Technologies and Johns-Manville

Bystander Exposure

Even without touching asbestos directly, Local 494 members reportedly worked alongside other tradespeople whose work released asbestos fibers continuously:

Pipefitters and steamfitters cutting and applying asbestos pipe insulation manufactured by Johns-Manville
Insulation workers removing and installing boiler lagging and thermal block insulation products including Kaylo, Thermobestos, Aircell, and Monokote
Boilermakers working on asbestos-covered boiler systems
Sprayed fireproofing applicators applying asbestos-containing materials to structural steel

Occupational health literature documents that bystander exposure from nearby insulation work can be as hazardous as direct handling. Local 494 members reportedly worked alongside these trades in confined spaces with limited ventilation—boiler rooms, turbine halls, cable tunnels, pipe chases, and basement mechanical areas—where fiber concentrations could reach extreme levels.

Renovation and Demolition Work

Electricians rewiring or upgrading older industrial and commercial buildings routinely disturbed existing asbestos-containing materials:

Cutting through asbestos fireproofing on structural steel to run new conduit
Removing asbestos-insulated wiring manufactured by General Electric and Westinghouse
Working around degraded sprayed-on asbestos fireproofing on ceilings, beams, and walls

Occupational health research identifies renovation work as producing some of the highest fiber releases, because degraded asbestos materials become friable and release fibers readily when disturbed.

Specific Facilities Where Local 494 Members May Have Been Exposed

Wisconsin Electric Power Company (We Energies) Generating Stations

Local 494 members reportedly performed construction, maintenance, and upgrade work at multiple We Energies facilities.

Valley Power Plant (Milwaukee)

Located on the Menomonee River, this facility reportedly contained extensive asbestos pipe insulation manufactured by Johns-Manville, boiler lagging products including Kaylo and Thermobestos, turbine insulation, and asbestos-containing gaskets from Garlock Sealing Technologies (per civil litigation documents). Local 494 members may have been exposed through both electrical component work and proximity to insulation and boiler maintenance activity.

Port Washington Power Plant (Ozaukee County)

A major generating station constructed in the 1930s with substantial post-World War II expansion. Local 494 members reportedly performed extensive electrical construction and maintenance involving Westinghouse switchgear with asbestos arc chutes. Occupational health literature documents asbestos insulation on turbines, boilers, piping manufactured by Johns-Manville and Thermal Industries, and heat exchangers throughout this type of facility.

Oak Creek Power Plant (Milwaukee County)

A large coal-fired power complex built in the 1950s and later expanded. Asbestos litigation filings allege this facility reportedly contained substantial quantities of asbestos insulation and fireproofing products including Aircell, Monokote, and pipe insulation from Johns-Manville. Local 494 electricians reportedly performed original construction and ongoing maintenance work involving General Electric and Westinghouse electrical equipment.

A.O. Smith Corporation Manufacturing Complex

Location: North Milwaukee Operations: Automobile frames, pressure vessels, and water heaters

Local 494 members performing electrical maintenance and construction work at this facility may have been exposed to asbestos from boiler room insulation manufactured by Johns-Manville and Thermal Industries—including lagging products such as Kaylo and Thermobestos—as well as electrical switchgear components with asbestos arc barriers manufactured by General Electric and Westinghouse, and sprayed fireproofing on structural members.

Allis-Chalmers Manufacturing Company (West Allis)

One of the largest heavy industrial complexes in the United States. Allis-Chalmers manufactured turbines, generators, electrical transformers, farm equipment, and industrial machinery. Asbestos use at this facility is well-documented in occupational health literature and asbestos litigation.

Local 494 members may have been exposed to asbestos from turbine insulation manufactured by Johns-Manville and Thermal Industries, transformer components with asbestos-insulated windings, arc chutes in General Electric and Westinghouse switchgear, asbestos pipe insulation from Johns-Manville throughout the facility, and boiler systems with asbestos lagging including Kaylo and Thermobestos.

Harnischfeger Industries / P&H Mining Equipment (West Milwaukee)

Operations: Mining shovels, cranes, and industrial equipment — foundry and fabrication

Local 494 electricians performing construction and maintenance at this facility may have been exposed to asbestos from high-temperature insulation manufactured by Johns-Manville and Thermal Industries, asbestos-containing electrical panel backboards, and high-temperature wiring with asbestos insulation manufactured by General Electric and Westinghouse.

Milwaukee County Medical Complex and Major Hospital Campuses

Hospital campuses built from the 1940s through the 1970s reportedly incorporated asbestos in boiler room pipe insulation manufactured by Johns-Manville and Eagle-Picher, floor tiles manufactured by Armstrong World Industries and Celotex, ceiling tiles manufactured by Johns-Manville and Georgia-Pacific, and mechanical room insulation throughout. Local 494 electricians may have been exposed during original construction and during renovation projects where existing asbestos-containing materials were disturbed.

Milwaukee High-Rise Commercial Construction (1960s–1970s)

Milwaukee saw substantial commercial construction during this period. Sprayed-on asbestos fireproofing—including Monokote and similar products manufactured by Combustion Engineering and others—was the standard material applied to structural steel in multi-story construction during this era. Electricians running conduit and pulling wire while spray fireproofing was being applied, or working in spaces where it had recently been applied, may have been exposed to airborne asbestos fibers. Occupational health research has thoroughly documented this form of construction-site bystander exposure.

Ladish Company (Cudahy, Wisconsin)

Operations: Forged metal components for aerospace and industrial applications

Local 494 electricians who performed work at this facility may have been exposed to asbestos in connection with furnace equipment insulation manufactured by Johns-Manville and Thermal Industries, heat-treating equipment with asbestos-insulated electrical components, and electrical systems supporting industrial furnaces with asbestos-insulated high-temperature wiring.

Milwaukee Road Railroad Maintenance Shops

Operations: Chicago, Milwaukee, St. Paul and Pacific Railroad repair and maintenance

Local 494 members working on electrical systems at these shops may have been exposed to asbestos from boiler room and steam-generating equipment with insulation and lagging products manufactured by Johns-Manville and Thermal Industries, electrical components with asbestos-containing insulation and arc chutes, and asbestos materials in locomotives and railcars undergoing repair.

Your Legal Options: Wisconsin Mesothelioma Settlements and Trust Funds

Workers diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer may be entitled to compensation through multiple avenues.

Personal Injury Claims Under Wisconsin Law

Under Wis. Stat. § 893.54, Wisconsin imposes a three-year statute of limitations for asbestos-related personal injury claims, measured from the date of diagnosis. Missing this deadline eliminates your right to recover. Claims may be brought against current and former employers, manufacturers of asbestos-containing products used in the workplace, and property owners under premises liability theories.

Asbestos Bankruptcy Trust Funds

Dozens of manufacturers who supplied asbestos-containing products to Wisconsin worksites—including Johns-Manville, Eagle-Picher, Owens Corning, W.R. Grace, Combustion Engineering, and Armstrong World Industries—have filed for bankruptcy and established asbestos trust funds to compensate workers. These trusts hold billions of dollars specifically for victims. You can file trust claims simultaneously with litigation, and many Local 494 members qualify to file against multiple trusts based on the range of products they encountered.

Workers’ Compensation

Wisconsin workers’ compensation may provide wage replacement and medical benefits for occupational disease. However, workers’ compensation does not preclude civil claims against product manufacturers — the two routes run in parallel, and pursuing one does not waive the other.
