Workers at the International Paper facility in St. Louis, Missouri may have been exposed to asbestos-containing materials during the 1960s through 1990s. Mesothelioma, asbestosis, and lung cancer carry latency periods of 20 to 50 years — workers who may have been exposed in the 1970s are receiving diagnoses today.
If you or a family member has been diagnosed after working at this facility or a similar paper mill, compensation may still be available through asbestos trust funds and civil litigation. The window to act is open now — but it will not stay open.
General Equipment at International Paper Co. St. Louis
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
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Missouri Department of Natural Resources (Missouri DNR) 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 Missouri DNR 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 International Paper Co. St. Louis
Exposure at paper mills was not limited to workers who handled insulation directly. Airborne fibers travel. Enclosed mechanical spaces with limited ventilation spread contamination across trades.
Thermal Insulators (Laggers)
Thermal insulators worked directly with pipe covering, block insulation, and insulating cement — mixing, cutting, fitting, and finishing materials that released fiber clouds when disturbed. Members of Heat and Frost Insulators Local 1 — the St. Louis-based local whose jurisdiction covers Missouri and portions of southern Illinois — who worked at paper facilities during peak asbestos decades faced some of the highest documented occupational exposure levels of any trade. Local 1 members routinely contracted out to industrial facilities across the Mississippi River corridor, meaning a single insulator’s career may have spanned International Paper, Labadie, Portage des Sioux, Granite City Steel, and Monsanto over the course of a working lifetime.
Pipefitters and Steamfitters
Members of UA Local 562 — the United Association local representing pipefitters and steamfitters in the St. Louis metropolitan area — worked throughout the steam and condensate systems at paper and industrial facilities across both sides of the river. Their tasks included:
- Cutting into existing insulation to reach valves, flanges, and pipe sections
- Reinsulating systems after repair
- Replacing steam traps and condensate drains
- Maintaining continuous high-pressure steam infrastructure
Steam system maintenance at a paper mill was essentially non-stop. UA Local 562 members who rotated among industrial clients in the St. Louis corridor may have accumulated exposure at multiple sites in addition to International Paper.
Boilermakers
Members of Boilermakers Local 27 — based in St. Louis and representing boilermaker craftworkers across Missouri and the region — who maintained and repaired plant boilers allegedly encountered:
- Asbestos-containing refractory materials inside boiler fireboxes
- Gaskets on access plates and pressure vessels
- Insulating cement applied to external boiler surfaces
Boiler work required disturbing both internal refractory linings and external insulation in confined, poorly ventilated boiler rooms. Local 27 members who worked turnarounds and outages at paper mills, power stations, and steel facilities along the Mississippi River corridor are among those most frequently identified in Missouri mesothelioma litigation.
Millwrights and Maintenance Mechanics
Millwrights moved across the entire facility. Their work involved:
- Repairing paper machines, dryer sections, pumps, and compressors
- Replacing pump and valve packing materials
- Removing and replacing gaskets on flanged equipment
- Working in enclosed spaces alongside insulated machinery
Electricians
Electricians working in panel rooms, control houses, and motor control centers may have encountered asbestos-containing millboard in electrical enclosures, electrical arc barriers with asbestos components, and bystander exposure from insulated pipes and equipment in the same confined spaces.
Carpenters and Construction Trades
During construction, expansion, and renovation projects, carpenters allegedly encountered spray fireproofing on structural steel, asbestos-containing floor tile in production and office areas, and roofing materials historically known to contain asbestos. Renovation of older structures is particularly hazardous — previously stable asbestos-containing materials become friable and release fibers when disturbed by cutting, drilling, or demolition.
Paper Machine Operators and Production Workers
Production workers who spent extended shifts near dryer sections, press sections, and wet-end areas may have experienced bystander exposure. Steam leaks in aging infrastructure disturbed insulation and released fibers into the general work environment — exposure no one asked for and no one logged.
Warehouse and Shipping Personnel
Workers who loaded, unloaded, and moved materials may have encountered asbestos-containing insulation or gasket materials on equipment components or in damaged packaging.
Secondary Exposure — Family Members
Workers who allegedly carried asbestos fibers home on clothing, hair, skin, and tools may have exposed family members who never set foot in the plant:
- Spouses who laundered work clothing
- Children with close contact during meals or evening routines
- Other household members who handled contaminated work gear
Secondary exposure is a recognized basis for legal claims in Missouri and nationally. Missouri courts and Illinois venues have litigated paraoccupational mesothelioma cases arising from the Mississippi River industrial corridor. If you developed mesothelioma without ever working in heavy industry, your spouse’s or parent’s employment history matters.
⚠️ Critical Filing Deadline
Missouri law gives mesothelioma and asbestos-disease victims 5 years from the date of medical diagnosis to file a personal injury lawsuit (Mo. Rev. Stat. § 516.120). For wrongful death claims after an asbestos-related death, the filing window is 3 years from the date of death (Mo. Rev. Stat. § 537.100). Miss either deadline by a single day and the right to file is permanently gone. No exceptions, no extensions.
About the two deadlines: Missouri keeps the personal-injury clock (Mo. Rev. Stat. § 516.120) and the wrongful-death clock (Mo. Rev. Stat. § 537.100) on separate tracks. The 5 years personal-injury deadline runs from the date of diagnosis and applies to the diagnosed person's own claim while they are alive. The 3 years wrongful-death deadline runs from the date of death and applies to surviving family members. The two are independent — preserving one does not extend the other, and an asbestos attorney with experience in Missouri can keep both options open as the situation evolves.
The personal-injury clock runs from the date of medical diagnosis — not from the date of asbestos exposure. Mesothelioma can take 20 to 50 years to develop after exposure. Many workers are only now receiving diagnoses from exposures that occurred decades ago.
Treat the 5 years deadline as a hard outer limit, not a planning horizon.
⚠️ Why You Must Act Now
Missouri's filing window may sound like ample time. It is not. Every month that passes after a mesothelioma diagnosis is a month in which your case gets harder to build and your options narrow.
Witnesses Become Harder to Reach
The tradespeople who worked alongside mesothelioma victims at facilities of this era are now in their 70s and 80s. Witnesses from many years ago are harder and harder to contact by the day — coworkers who can testify about which asbestos-containing materials were used, who supplied them, and how the work was done are increasingly difficult to locate. Once first-hand testimony becomes unavailable, that record is gone.
Records Disappear
Employment records, union records, purchasing records, and product invoices that document exactly which asbestos-containing materials were used at this facility are being lost every year. Plants close. Corporate owners change. Storage facilities are cleared. Records that existed five years ago may not exist today.
Mesothelioma Cases Are Complex to Build
Identifying every responsible manufacturer and every jobsite across a tradesperson's career requires intensive investigation by experienced toxic-tort counsel. A case against the manufacturers who supplied asbestos-containing materials to this facility may involve dozens of defendants. That investigation takes time that waiting families do not have.
Asbestos Trust Fund Claims Run on a Separate Track
More than 60 asbestos bankruptcy trusts exist to compensate victims whose exposures came from manufacturers that have since gone bankrupt — including the Manville Personal Injury Settlement Trust, established after the 1982 Johns-Manville bankruptcy. Each trust has its own claim forms, exposure criteria, documentation requirements, and processing timelines. Pursuing trust-fund compensation in parallel with a lawsuit takes months. The trust-fund process should start now, not after you decide whether to file suit.
What To Do Next
If you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease — and you worked at this facility, lived with someone who did, or worked at neighboring industrial sites in the corridor — the practical next steps are:
- Speak with an asbestos attorney with experience in Missouri. The first conversation is free, confidential, and creates no obligation. An experienced attorney will help you understand which trust-fund claims may apply, which civil claims are viable, and what documentation you should start gathering.
- Gather what you can about your work history. Pay stubs, W-2s, union cards, photographs, names of coworkers, and dates of employment all become important evidence. The WorkChain widget on this page can help you organize and email yourself a copy of your facility list.
- Preserve your medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests all become part of the legal record. Ask your treating physicians for full copies of everything in your chart.
- Identify household members who may also have been exposed. Spouses who laundered work clothing and children who hugged a parent returning from the plant are eligible for secondary-exposure claims when they have been diagnosed with an asbestos-related disease.
- Act before the filing deadline runs. Missouri's statute of limitations is a hard outer limit. Even if you are still in the middle of treatment decisions, beginning the legal process early preserves your options.

Asbestos-Related Diseases
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.
