About National Stockyards
Scale and Operations
The National Stockyards in National City, Illinois — directly across the Mississippi River from St. Louis, Missouri — was one of the largest livestock and meatpacking operations in the American Midwest. Established in 1873, the complex processed millions of cattle, hogs, and sheep annually at its peak and employed thousands of workers across a broad range of trades and production roles:
- Animal handling and slaughter
- Rendering and processing
- Refrigeration and cold-storage management
- Steam and hot-water infrastructure
- Electrical systems and maintenance
- Construction and renovation
The complex encompassed dozens of buildings, extensive steam and hot-water piping networks, boiler rooms, refrigeration plants, and electrical systems — all of which reportedly required substantial quantities of thermal insulation and fireproofing materials.
The National Stockyards was not an isolated industrial site. It operated within the same Mississippi River industrial corridor that also included major Missouri facilities across the river — among them the Labadie Energy Center, the Portage des Sioux Power Plant, Granite City Steel, and the Monsanto industrial complex in the greater St. Louis area. Workers, union contractors, and tradespeople moved among these sites throughout their careers. A pipefitter who worked at the Stockyards in the 1960s may also have put in time at Granite City Steel or on Missouri-side industrial plants; the same union halls supplied labor to all of them.
Facility Decline
Operations declined during the latter half of the twentieth century as the meatpacking industry consolidated and shifted geographically. Large-scale livestock trading eventually ceased, and much of the complex was demolished or repurposed. The health consequences for workers who built and maintained that complex, however, did not end with the facility.
General Equipment at National Stockyards
The equipment below represents the systems and infrastructure documented or typically present at this facility during the era when asbestos-containing materials were specified in industrial construction. This is general facility-equipment reference — not a legal attribution of any specific product, manufacturer, or exposure event to this facility. Material-category and manufacturer information is addressed in the AsbestosIndex Product Crosswalk linked under the records table below.
Documented Asbestos Evidence — Illinois
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Illinois Environmental Protection Agency (Illinois EPA) was notified under federal NESHAP rules, the work was logged, and the asbestos-containing material was confirmed and removed under regulated conditions. These are not allegations or estimates — they are paper records tying documented asbestos-containing material to this specific site.
No Illinois EPA NESHAP abatement notifications have been identified for this facility in current public records. Per the framing above, absence of state-agency documentation should not be read as absence of asbestos — only as absence of a formal, regulated abatement event meeting reporting thresholds. Workers who recall encountering pipe insulation, block insulation, gaskets, or other asbestos-era construction materials at this facility may still have viable claims regardless of whether a state record exists.

Who May Have Been Exposed at National Stockyards
Insulators
Heat and Frost Insulators were among the most heavily exposed workers at any industrial facility. In the St. Louis region, insulation contractors were supplied largely through Heat and Frost Insulators Local 1 — one of the oldest and most active insulator locals in the country, with jurisdiction covering both sides of the Mississippi River. Insulators who worked at the National Stockyards under Local 1 may have:
- Applied and removed pipe covering on steam and hot-water distribution systems
- Installed block insulation and insulating cement on boilers and equipment
- Cut, fitted, and sanded insulation materials — work that routinely generated high airborne fiber concentrations
- Conducted maintenance in confined spaces with limited ventilation
- Rotated between the Stockyards and other corridor facilities including Granite City Steel, Labadie, and Portage des Sioux, accumulating exposure at multiple sites
Pipefitters and Steamfitters
Pipefitters on high-pressure steam systems and process piping throughout the complex were represented in the St. Louis area by UA Local 562 — the United Association local covering pipefitters, steamfitters, and plumbers throughout much of Missouri and the greater St. Louis region. Workers dispatched from Local 562 to National City may have:
- Disturbed existing insulation when making connections or repairs
- Installed new pipe sections alongside asbestos-containing insulation
- Worked directly beside insulators, absorbing fiber concentrations from neighboring trades
- Spent extended hours in mechanical rooms where insulation dust settled and was repeatedly disturbed
- Worked across the river on Missouri industrial sites between assignments at the Stockyards
Boilermakers
Boilermakers maintaining and repairing industrial boilers at the National Stockyards were frequently members of Boilermakers Local 27 based in the St. Louis area. Local 27 supplied labor to industrial facilities throughout Missouri and Illinois, including power plants and heavy industry along the Mississippi River corridor. Boilermakers who may have worked at the Stockyards allegedly encountered:
- Refractory materials and insulating cement in boiler interiors and casings
- Gasket materials and thermal insulation during every repair cycle
- Confined spaces with poor airflow — conditions that concentrate fiber levels sharply
- Work environments similar to those found at Missouri facilities like Labadie and Portage des Sioux, where the same Local 27 members may also have been dispatched
Electricians
Electricians at the National Stockyards may have encountered asbestos-containing materials in:
- High-temperature electrical wire insulation
- Panel board materials and switchgear components
- Spray fireproofing applied to structural steel in mechanical and electrical rooms
- Drilling and cutting through fireproofed structural members
Carpenters and Construction Trades
Workers involved in construction and renovation over the facility’s multi-decade life may have been exposed to asbestos-containing materials including:
- Floor tiles and mastic adhesive
- Acoustic and fire-rated ceiling tiles
- Roofing materials incorporating asbestos-containing felts
- Joint compound and drywall finishing materials
Maintenance Workers and Janitors
Maintenance and janitorial staff are frequently overlooked in asbestos exposure claims — and frequently among the most heavily exposed over their careers. These workers:
- Swept and cleaned mechanical rooms and production areas daily
- Moved through buildings reportedly insulated with asbestos-containing materials throughout their shifts
- Disturbed settled fibers through routine cleaning activity
- Accumulated chronic exposure across years or decades on the job
Production and Non-Trades Workers
Meatpacking and production workers who spent shifts in older buildings heated and insulated with these materials may have been exposed to asbestos-containing materials, particularly when:
- Overhead insulation was deteriorating
- Maintenance activities were being conducted nearby
- Ventilation was poor
Illinois — Filing Deadline & Next Steps
Illinois law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (735 ILCS 5/13-202). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (740 ILCS 180/2). The two deadlines run on separate tracks — preserving one does not extend the other.
The personal-injury clock runs from diagnosis, not from exposure. Mesothelioma latency is typically 20 to 50 years, so workers exposed in the 1950s–1980s are being diagnosed today.
Practical first steps
- Document what you remember. Pay stubs, W-2s, union cards, photographs, coworker names, and dates of employment. The WorkChain widget on this page can save a copy you can email yourself.
- Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
- Identify household members. Spouses who laundered work clothing and children of plant workers are eligible for secondary-exposure claims when diagnosed with an asbestos-related disease.
- Speak with an asbestos attorney with Illinois experience. The first conversation is free and confidential. Asbestos trust-fund claims and civil claims run on different tracks — both can be pursued in parallel.
Asbestos-Related Diseases — Illinois
Asbestos fiber exposure can cause several specific diseases that typically appear decades after the original exposure. The latency period — the gap between exposure and diagnosis — usually runs 20 to 50 years. That's why workers exposed in the 1960s, 1970s, and 1980s are receiving diagnoses today.
Mesothelioma
A rare, aggressive cancer that affects the lining of the lungs (pleural mesothelioma), abdomen (peritoneal), or heart (pericardial). Mesothelioma is almost exclusively caused by asbestos exposure, which is why a mesothelioma diagnosis often points directly to historical workplace exposure. Average latency from first exposure to diagnosis is 30-50 years.
Asbestosis
A chronic, non-cancerous scarring of lung tissue caused by inhaled asbestos fibers. Asbestosis causes progressive shortness of breath, persistent cough, and reduced lung function. It does not improve with treatment, and it is a recognized basis for compensation under most trust schedules and civil claims.
Lung Cancer
Asbestos exposure significantly increases the risk of lung cancer, particularly when combined with a history of smoking. Asbestos-related lung cancer is compensable under the same trust schedules and civil claim avenues as mesothelioma.
Other Recognized Diseases
Pleural plaques, pleural thickening, laryngeal cancer, ovarian cancer, and certain gastrointestinal cancers are also recognized as asbestos-related under various trust schedules and case-law authorities, though eligibility and proof requirements vary by claim type.
If you have any of these diagnoses and you worked at this facility, lived with someone who did, or were exposed in any documented capacity, you may have a claim worth pursuing. Speak with an attorney before assuming you don't qualify.
