Asbestos in Chicago: 12 Industrial Sites Where Workers Were Exposed for Decades

Chicago's industrial identity was forged in steel, smoke, and fire—and for much of the twentieth century, asbestos was woven into every layer of it.^[4] From the blast furnaces of South Works to the boiler rooms of Commonwealth Edison power plants, at least 12 major industrial sites across the Chicago metropolitan area exposed workers to this toxic mineral on a daily basis for decades.^[6] Illinois now ranks among the top 10 states in the nation for mesothelioma deaths, with 120 to 150 fatalities reported annually, a direct legacy of the city's industrial past.^[8]

What Are the Key Facts About Asbestos Exposure in Chicago?

• Chicago's South Side steel corridor — stretching from US Steel South Works through Republic Steel and into East Chicago's Inland Steel — employed hundreds of thousands of steelworkers who were routinely exposed to asbestos insulation, lagging, and fireproofing materials
• Commonwealth Edison operated the Fisk Generating Station (1903-2012) and Crawford Generating Station (1924-2012) in Chicago, both of which used asbestos extensively in boiler insulation, turbine packing, and pipe covering for decades
• The Chicago & North Western Railroad and other Class I railroads operating out of Chicago used asbestos in locomotive insulation, brake shoes, steam pipe lagging, and railcar construction through the 1970s
• Illinois ranks among the top 10 states for mesothelioma mortality, reporting approximately 120 to 150 deaths per year according to CDC mortality data
• The Illinois statute of limitations for mesothelioma claims is 2 years from date of diagnosis under 735 ILCS 5/13-202, with a discovery rule applied by Illinois case law
• Cook County, Madison County, and St. Clair County are historically favorable asbestos litigation venues in Illinois
• SB 328, signed into law in 2025, expanded toxic tort jurisdiction in Illinois, broadening access to Illinois courts for workers exposed to asbestos in the state
• Oil refineries in Whiting, Indiana, and Lemont, Illinois — both within the Chicago industrial region — used asbestos insulation in catalytic crackers, distillation columns, and piping systems throughout their operations
• The Union Stock Yards, which operated from 1865 to 1971, used asbestos insulation in refrigeration systems, boiler rooms, and processing equipment throughout the meatpacking complex
• Lake Michigan sediment contamination from decades of industrial discharge includes asbestos-containing waste from steel mills and manufacturing operations along the southern lakeshore
• Current asbestos exposure risks persist in Chicago through renovation and demolition of pre-1980 buildings and maintenance of aging CTA infrastructure
• Workers at highest risk include steelworkers, boilermakers, pipefitters, electricians, railroad workers, power plant operators, auto mechanics, and construction tradespeople

Why Did Chicago Become an Asbestos Exposure Epicenter?

Chicago's position at the convergence of Great Lakes shipping, transcontinental rail networks, and the Illinois waterway system made it the industrial engine of the Midwest. By the early twentieth century, the city hosted an unparalleled concentration of steel mills, power plants, oil refineries, railroad operations, and manufacturing facilities — virtually all of which relied on asbestos-containing materials for thermal insulation, fire protection, and equipment durability.

The mineral was not a minor component in these operations. It was structural. Steel mills used insulating blankets around blast furnaces and lined piping throughout sprawling facilities. Power plants packed their boilers and turbines with it. Railroads insulated locomotive boilers and steam lines with products containing the toxic fibers. The scale of industrial activity meant that exposure affected entire communities across the South Side, Southeast Side, and the Calumet industrial corridor.

"Chicago's industrial workers were exposed from every direction—the insulation in the pipes above them, the fireproofing on the walls beside them, the gaskets and packing in the equipment they operated. When a steelworker or power plant operator tells me their story, the toxic material was literally everywhere in their workplace for 20 or 30 years."

According to the Occupational Exposure Index, steel mills, power plants, and railroad facilities rank among the highest-risk work environments for asbestos-related disease — and Chicago had all three in extraordinary concentration.

Which Steel Mills Exposed Chicago Workers to Asbestos?

US Steel South Works

US Steel South Works, at the mouth of the Calumet River on Chicago's South Side, operated from 1882 to 1992 and employed as many as 20,000 workers at its peak. The mineral was used in blast furnace insulation, ladle linings, coke oven door seals, steam pipe insulation, and electrical wiring. Workers in maintenance, bricklaying, pipefitting, and boiler operations faced the most intense daily exposure. The WikiMesothelioma profile on steel mill workers documents the range of asbestos-containing materials standard in integrated steel operations.

Republic Steel (Southeast Side)

Republic Steel operated a major facility on Chicago's Southeast Side along the Calumet River, using toxic insulation in furnaces, rolling mills, and piping networks. Workers in the coke plant, blast furnace area, and maintenance departments were exposed during routine operations and overhauls. Those who performed furnace relining faced especially heavy exposure stripping deteriorated insulating materials.

Inland Steel (East Chicago / Indiana Harbor)

Just across the state line in East Chicago, Indiana, Inland Steel's Indiana Harbor Works was functionally part of Chicago's industrial ecosystem. Many workers lived in Chicago and commuted. Inland Steel operated one of the largest basic oxygen furnace shops in the world, with toxic insulation integral to thermal management. Workers employed there between the 1940s and 1970s may have claims in both Illinois and Indiana jurisdictions. For workers who also spent time in steel mill and foundry operations at other facilities, exposure histories are often cumulative.

"The Calumet corridor — from South Works through Republic Steel and across to Inland Steel in East Chicago — was one continuous asbestos exposure zone. Workers moved between mills. They carried fibers home on their clothes. Entire families were affected by what happened inside those plants."

— Yvette Abrego, Senior Client Manager, Danziger & De Llano

How Did Chicago's Power Plants Contribute to Asbestos Exposure?

Coal-fired power generation was the backbone of Chicago's electricity supply for most of the twentieth century, and every major generating station in the city was heavily insulated with hazardous materials. The WikiMesothelioma Power Plant Workers resource documents how boiler insulation, turbine packing, condenser gaskets, and pipe lagging in power plants created some of the highest occupational asbestos exposure levels recorded in any industry.

Fisk Generating Station

Commonwealth Edison's Fisk Generating Station, located on the Chicago Sanitary and Ship Canal in Pilsen, operated from 1903 to 2012. Over its 109-year life, Fisk's boilers, turbines, and steam systems were insulated and re-insulated with hazardous materials. Boiler workers, turbine mechanics, pipefitters, and electricians who worked at Fisk faced daily toxic fiber exposure.

Crawford Generating Station

The Crawford Generating Station in Little Village operated from 1924 to 2012 with a similar toxic exposure profile. Crawford's four generating units were maintained by crews who regularly disturbed hazardous insulation during boiler inspections, tube replacements, and turbine overhauls.

Other Commonwealth Edison Facilities

Commonwealth Edison (now Exelon) operated additional stations across the metro area, including the Waukegan, Joliet, and Will County generating stations. All used the same toxic insulation. Workers who rotated between stations built cumulative exposure histories spanning multiple facilities.

What Role Did Railroads and Other Industries Play in Chicago's Asbestos Legacy?

Chicago & North Western Railroad

Chicago was the railroad capital of America. Railroad workers in locomotive maintenance shops, roundhouses, and railcar repair facilities were exposed to the mineral in boiler insulation, steam pipe lagging, brake shoes, and railcar undercoating. The Chicago & North Western's West Side maintenance facilities employed thousands who handled asbestos daily. Other major railroads — Burlington Northern, Illinois Central, and Chicago, Rock Island & Pacific — had similar exposure profiles.

Oil Refineries: Whiting and Lemont

The BP Whiting Refinery in Whiting, Indiana, and petrochemical operations in Lemont used the toxic material extensively in catalytic crackers, distillation towers, heat exchangers, and miles of high-temperature piping. Refinery workers — especially insulators, boilermakers, and maintenance mechanics — faced chronic exposure during turnaround periods when insulation was stripped and reinstalled. Workers in oil refinery and petrochemical operations throughout the Chicago region share similar exposure histories with their counterparts in Gulf Coast refineries.

Union Stock Yards

The Union Stock Yards operated on Chicago's South Side from 1865 to 1971 as the center of the American meatpacking industry. While meatpacking is not typically associated with asbestos, the Stock Yards' infrastructure—refrigeration plants, boiler houses, rendering facilities, and cold storage buildings—relied on toxic insulation for thermal management. Maintenance workers, boiler operators, and refrigeration mechanics were exposed to hazardous fibers in pipe insulation, boiler lagging, and equipment gaskets.

Auto Manufacturing and Parts Plants

Chicago and its suburbs hosted numerous auto parts manufacturing and assembly operations. The Ford Assembly Plant in Chicago Heights and various brake and clutch manufacturers used asbestos-containing materials. Auto mechanics servicing vehicles with toxic brake pads and clutch facings at shops across Chicago were also exposed during routine work.

"People are often surprised when I tell them that meatpacking workers and auto mechanics are among our clients. They think asbestos exposure only happened in shipyards and steel mills. But Chicago's industrial base was so broad that asbestos touched nearly every trade in the city — from the Stock Yards to the railroad shops to the neighborhood brake repair garage."

What Are the Current Asbestos Exposure Risks in Chicago?

While the era of heavy industrial asbestos use has ended, Chicago's built environment still contains enormous quantities of hazardous materials in buildings constructed before 1980. The Illinois EPA regulates abatement and requires notification before renovation or demolition, but improper removal and deterioration of aging materials continue to create exposure risks.

The Chicago Transit Authority's infrastructure—including older rail stations, tunnel systems, and maintenance facilities—contains the mineral in insulation, fireproofing, and floor materials. CTA workers performing maintenance on these older systems face ongoing exposure risk, as do contractors on station rehabilitation projects.

Renovation and demolition of Chicago's aging building stock presents another persistent pathway. Floor tiles, pipe insulation, plaster, and roofing materials in pre-1980 buildings frequently contain the mineral. Workers performing gut renovations or demolition without proper surveys and abatement can release fibers into the air.

Lake Michigan sediment contamination from decades of industrial discharge along the southern lakeshore also represents a legacy concern. Steel mills and manufacturing facilities discharged contaminated waste into the Calumet River system and directly into the lake for decades.

What Legal Options Do Chicago Asbestos Workers Have?

Illinois provides multiple legal pathways for workers diagnosed with mesothelioma or other asbestos-related diseases after exposure at Chicago-area industrial sites.

Illinois Statute of Limitations

Under 735 ILCS 5/13-202, Illinois imposes a 2-year statute of limitations for both personal injury and wrongful death claims. Courts apply a discovery rule: the filing deadline begins when the plaintiff knew or should have known that asbestos caused their injury — not from the date of exposure. For mesothelioma, this typically means 2 years from diagnosis. Acting promptly is critical to preserve all legal options.

Favorable Litigation Venues

Illinois has long been one of the most favorable states for asbestos litigation. Cook County Circuit Court handles a high volume of asbestos cases with efficient procedures. Madison County and St. Clair County in southern Illinois are also well-established venues with experienced judges. The 2025 passage of SB 328 expanded toxic tort jurisdiction, broadening access to Illinois courts for workers exposed to asbestos in the state.

Asbestos Trust Fund Claims

More than $30 billion remains in asbestos bankruptcy trust funds established by companies that supplied products used at Chicago industrial sites. Many workers qualify for claims against multiple trusts — a steelworker at South Works may have been exposed to products from Johns-Manville, Owens Corning, and Pittsburgh Corning, each with a separate trust. An experienced mesothelioma attorney can identify all applicable trusts and coordinate filings to maximize recovery.

"Illinois workers have real advantages when it comes to asbestos litigation. The courts here understand these cases. The discovery rule protects workers who were exposed decades ago. And SB 328 has made it even clearer that Illinois is the right place to bring these claims. But the 2-year deadline is firm — we always tell families to call us as soon as they receive a diagnosis."

Who Should Take Action After Asbestos Exposure in Chicago?

If you worked at any of the following types of facilities in the Chicago metropolitan area, you may have been exposed to asbestos and should monitor your health and consult with a mesothelioma attorney:

• Steel mills: US Steel South Works, Republic Steel, Wisconsin Steel, Acme Steel, or Inland Steel (East Chicago)
• Power plants: Commonwealth Edison facilities including Fisk, Crawford, Waukegan, Joliet, or Will County generating stations
• Railroads: Chicago & North Western, Burlington Northern, Illinois Central, or any railroad maintenance facility in the Chicago area
• Oil refineries: BP Whiting Refinery, Citgo Lemont Refinery, or any petrochemical facility in the Calumet industrial corridor
• Meatpacking: Union Stock Yards or any associated processing, rendering, or cold storage facility
• Auto manufacturing: Ford Chicago Heights, brake and clutch parts manufacturers, or automotive repair shops operating before 1980
• Construction trades: Any insulation, demolition, renovation, or HVAC work in pre-1980 Chicago buildings
• CTA infrastructure: Maintenance, repair, or construction work on CTA rail stations, tunnels, or facilities

Workers exposed at one Chicago site often have histories at multiple facilities, particularly those in construction trades who moved between employers. Workers who also served in the military may have additional exposure from environmental asbestos sources or military installations. Each source strengthens a compensation claim.
