Missouri’s asbestos burden is rooted in the manufacturing, lead smelting, and railroad industries that powered the state’s economy through the 20th century. St. Louis and Kansas City were industrial centers where thousands of workers handled asbestos-containing products in factories, refineries, rail yards, and construction sites.
The state’s 273 documented exposure sites have produced more than 1,000 asbestos-related deaths. For families still receiving diagnoses decades after exposure ended, Missouri’s legal landscape offers one of the longest filing windows in the country and a court system with deep experience handling asbestos cases.

Where Exposure Happened
Missouri’s asbestos exposure traces to three primary industrial sectors that defined the state’s economy for more than a century.
Manufacturing and Lead Smelting
St. Louis was one of the largest manufacturing centers in the Midwest, part of an industrial corridor that extended through Chicago and across the Great Lakes states. The city’s factories produced automobiles, chemicals, electrical equipment, and building materials. Asbestos insulated boilers, pipes, and machinery across these facilities. Workers who installed, maintained, or operated near insulated equipment inhaled fibers throughout their careers.
The St. Louis metropolitan area was also home to lead smelting operations that relied on heat-resistant asbestos materials in furnaces and processing equipment. The Doe Run Company and other smelting facilities in the region used asbestos insulation extensively, exposing smelter workers, maintenance crews, and laborers.
Railroads
Missouri sits at the intersection of major rail corridors, and both St. Louis and Kansas City served as critical railroad hubs. The Burlington Northern Santa Fe Railway, Union Pacific, and Missouri Pacific Railroad operated maintenance yards, locomotive shops, and freight terminals across the state.
Railroad workers handled asbestos in brake linings, gaskets, pipe insulation, and locomotive components. Mechanics, boilermakers, and maintenance workers faced the heaviest exposure, but brakemen and conductors who worked in and around rolling stock were also affected. The Federal Employers Liability Act (FELA) provides a separate legal pathway for railroad workers with asbestos-related disease.
Construction and Power Generation
Missouri’s postwar building boom put thousands of construction workers in contact with asbestos-containing materials. Insulators, pipefitters, electricians, and drywall workers handled asbestos products daily on commercial and residential construction sites throughout St. Louis, Kansas City, and Springfield.
Power plants across the state, including the Labadie Energy Center and the Sioux Energy Center along the Missouri River, used asbestos to insulate boilers, turbines, and steam pipes. Workers who maintained these systems were exposed during routine repairs and overhauls.
Regional Data
| Region | Key Industries | Notable Sites |
|---|---|---|
| St. Louis Metro | Manufacturing, lead smelting, railroads | Anheuser-Busch, Mallinckrodt Chemical, rail yards |
| Kansas City Metro | Railroads, manufacturing, meatpacking | Burlington Northern yards, GM Fairfax plant |
| Springfield | Manufacturing, construction | Industrial facilities, commercial buildings |
| St. Charles County | Manufacturing, power generation | Weldon Spring, industrial corridors |
| Jefferson County | Lead smelting, mining | Doe Run, Herculaneum smelter |
The St. Louis metropolitan area accounts for a disproportionate share of the state’s asbestos cases, reflecting its concentration of heavy industry, manufacturing, and railroad operations. As a border city with Illinois, St. Louis shares an industrial corridor where workers often crossed state lines, complicating exposure histories but expanding legal options. Kansas City contributes a significant share as well, driven by its role as a major rail hub and manufacturing center.
Who Is Most at Risk
The occupations with the highest exposure in Missouri reflect the state’s industrial history. For national data on which trades carry the greatest risk, see the mesothelioma risk by occupation breakdown.
- Manufacturing workers at automotive, chemical, and electrical plants
- Lead smelter workers at Doe Run and other smelting operations
- Railroad workers in maintenance yards and locomotive shops across St. Louis and Kansas City
- Pipefitters and insulators in industrial and commercial construction
- Boilermakers at power plants and industrial facilities
- Construction tradespeople working in pre-1980 buildings
- Auto mechanics who serviced brakes and clutches containing asbestos
Secondary exposure has also affected Missouri families. Workers carried asbestos fibers home on clothing, exposing spouses and children. Take-home exposure has been the basis for several Missouri claims. A 2026 Virginia Supreme Court ruling on employer duty of care for secondary exposure could influence how Missouri courts evaluate these cases going forward.
Missouri has a five-year statute of limitations for personal injury claims, running from the date of diagnosis. Wrongful death claims must be filed within three years of death. These are among the longest filing windows in the country, but families should still consult an attorney early to preserve their options and gather exposure evidence while it remains available.
Legal Landscape
For an overview of all current treatment options, see the 2026 mesothelioma treatment landscape. St. Louis has been one of the most active jurisdictions for asbestos litigation in the country for decades. The city has appeared in the American Tort Reform Association’s Judicial Hellholes report for more than 20 years, a designation that reflects the volume and scale of asbestos cases filed there.
Recent Missouri mesothelioma verdicts include a $20 million award for a mechanic exposed to asbestos brake products, a $6 million mesothelioma verdict against Ford Motor Company, and a $1.3 million lung cancer settlement. St. Louis filings increased 21% in 2023, reflecting continued demand for asbestos case resolution.
Missouri law allows claims against both solvent companies and bankrupt defendants through asbestos trust funds. An experienced mesothelioma attorney can identify all applicable trusts based on a worker’s employment history and the products used at their specific jobsites.
How many people have died from mesothelioma in Missouri?▼
At least 897 people in Missouri have died from mesothelioma. An additional 246 have died from asbestosis, and an estimated 3,588 cases of asbestos-linked lung cancer have been recorded. The total asbestos-related death toll exceeds 1,000.
What is the statute of limitations for mesothelioma in Missouri?▼
Missouri has a five-year statute of limitations for personal injury claims, starting from the date of mesothelioma diagnosis. Wrongful death claims must be filed within three years of the date of death. These are among the longest deadlines in the country.
Which Missouri cities have the most asbestos exposure sites?▼
St. Louis and Kansas City lead the state in documented exposure sites, driven by their concentrations of manufacturing, railroads, and heavy industry. Springfield, St. Charles County, and Jefferson County also have significant exposure histories.
Why is St. Louis a major venue for asbestos lawsuits?▼
St. Louis has decades of experience handling asbestos cases, a large pool of affected workers from the city’s industrial history, and jury pools that understand the human impact of asbestos exposure. The city has appeared in the American Tort Reform Association’s Judicial Hellholes report for more than 20 consecutive years.
Can family members of Missouri workers file claims?▼
Yes. Missouri courts recognize take-home exposure claims, where family members developed mesothelioma from asbestos fibers carried home on workers’ clothing. The state’s five-year statute of limitations gives families additional time to pursue claims.
