⚠️ CRITICAL DEADLINE WARNING — READ THIS FIRST
Missouri law gives asbestos victims five years from the date of diagnosis to file a lawsuit — not five years from when you were exposed. Under Missouri § 516.120 RSMo, the clock starts the day a doctor confirms your mesothelioma, asbestosis, lung cancer, or pleural disease diagnosis. If you miss this deadline by even one day, Missouri courts will permanently bar you from recovering any compensation — no exceptions, no extensions, no second chances.
**That five-year window is now under active legislative threat of being cut to three years — and any change could apply to claims currently in progress. No one knows when a Senate vote will occur or how quickly the governor could sign it.
If you or a family member has been diagnosed with mesothelioma or another asbestos disease, do not wait to see what the legislature does. Call a Missouri mesothelioma attorney today.

If you worked at the Labadie Energy Center in Franklin County, Missouri — or if a family member did — and you’ve been diagnosed with mesothelioma, asbestosis, lung cancer, or pleural disease, asbestos exposure at this facility may be a contributing factor in your diagnosis. Public litigation records identify asbestos-containing products from Johns-Manville, Armstrong World Industries, Owens Corning, Owens-Illinois, Garlock Sealing Technologies, Eagle-Picher Industries, Celotex, W.R. Grace, Crane Co., and Combustion Engineering were present at Labadie. A qualified mesothelioma lawyer in Missouri can identify which manufacturers may be liable and pursue compensation before your legal window closes.

Missouri’s current statute of limitations for asbestos personal injury claims is five years from the date of diagnosis under § 516.120 RSMo. That is the law today. **Missouri Whether the legislature acts or not, every day you delay weakens your case: witnesses die, employment records disappear, and manufacturers’ evidence becomes harder to locate. The moment you receive a diagnosis, your legal clock starts running.

What Is the Labadie Energy Center?

The Labadie Energy Center sits along the Missouri River near the town of Labadie in Franklin County, approximately 35 miles west of downtown St. Louis. It is the largest coal-fired power plant in Missouri and sits at the heart of the Mississippi River industrial corridor — a stretch of heavy industry running along both banks of the Mississippi and its tributaries where workers from Missouri and Illinois spent entire careers moving between facilities.

Operator: Union Electric Company (original developer and operator), reorganized into Ameren Corporation in 1997; Ameren Missouri continues to operate the facility today
Construction: Began in the 1960s; first generating unit came online in 1970; additional units commissioned through the mid-1970s
Capacity: 573.7 megawatts across four coal-fired generating units
Service area: St. Louis metropolitan area and surrounding Missouri communities

The Scale of Industrial Operations at Labadie

The plant’s size determined the volume of asbestos installed and the number of workers exposed. The facility contains:

Multiple large coal-fired boilers operating at extreme temperatures and pressures, built with boiler components supplied by Combustion Engineering
Extensive high-pressure steam turbine systems connected to large electrical generators
Miles of high-temperature steam and condensate piping throughout the facility, insulated with Johns-Manville pipe covering and Kaylo block insulation
Feed water heaters, heat exchangers, and pressure vessels sealed with Garlock compressed sheet gaskets and Cranite gasket material
Large-scale cooling systems and associated pumping infrastructure sealed with Garlock valve packing
Electrical switchgear and control systems integrated throughout the plant

Every one of these systems — built and maintained from the late 1960s through the 1990s — relied on asbestos-containing materials: Kaylo pipe insulation, Thermobestos block insulation, Monokote fireproofing, Unibestos pipe covering, and Cranite sheet gaskets.

Why Asbestos Was Used at Power Plants Like Labadie

The Engineering Logic Behind Widespread Asbestos Exposure

Coal-fired power plants heat water to produce high-pressure steam, then route that steam through turbines to generate electricity. Main steam lines at Labadie carry steam exceeding 1,000 degrees Fahrenheit at pressures measured in hundreds of pounds per square inch. Every pipe, valve, flange, and piece of equipment operating at elevated temperature required thermal insulation.

For most of the twentieth century, asbestos dominated high-temperature industrial insulation. It offered properties no other affordable material could match:

Withstood extreme temperatures without burning or degrading
Could be manufactured into pipe covering such as Kaylo and Unibestos, block insulation such as Thermobestos and Aircell, asbestos cement, cloth, and rope
Could be shaped and fitted around virtually any surface
Was inexpensive and available in large quantities
Was distributed through a well-developed network of contractors and manufacturers serving Missouri industrial facilities — including the same insulation contractors who worked Labadie, Portage des Sioux, and the Granite City Steel complex across the river in Madison County, Illinois

A power plant the size of Labadie, built in the late 1960s and early 1970s, contained asbestos in virtually every insulated surface, every high-temperature gasket, every valve packing, and numerous other applications throughout the facility.

Specific Applications Where Asbestos Products Were Installed at Labadie

Boiler insulation and refractory systems

The massive coal-fired boilers — identified in litigation records as products of Combustion Engineering — were insulated with Armstrong World Industries block insulation and W.R. Grace Monokote asbestos cement. During boiler outages, insulation contractors removed and replaced this material in operations that generated enormous quantities of airborne asbestos fiber. Boilermakers represented by Boilermakers Local 27 out of St. Louis performed this work at Labadie and routinely rotated to other Missouri River and Mississippi River corridor facilities, including Portage des Sioux Power Plant in St. Charles County and industrial facilities along the Illinois bank.

High-temperature steam pipe covering

All high-pressure steam lines were insulated with preformed asbestos pipe covering — cylinders of asbestos insulation split lengthwise to fit around pipes of various diameters. At Labadie, this included Johns-Manville pipe insulation, Kaylo calcium silicate pipe covering manufactured by Owens-Illinois and later Owens Corning, and Unibestos pipe covering manufactured by Pittsburgh Corning. Cutting, fitting, and removing this covering was a primary source of asbestos exposure for insulators dispatched through Heat and Frost Insulators Local 1 in St. Louis and nearby trades workers.

Turbine insulation

Steam turbines were insulated with removable asbestos blankets and fitted Thermobestos block insulation supplied by Eagle-Picher Industries. Turbine overhauls required removal and replacement of this insulation, exposing boilermakers, turbine mechanics, and insulators to heavy fiber releases. Many of these same crews worked turbine outages at Portage des Sioux and at facilities in Madison County and St. Clair County, Illinois — carrying the same asbestos products across both sides of the Mississippi River industrial corridor.

Gaskets and valve packing

Virtually every flanged connection, valve stem, and pump seal used Garlock compressed sheet gaskets, Cranite gasket material manufactured by Crane Co., or Garlock valve packing during the facility’s peak operating years. When pipefitters represented by Plumbers and Pipefitters UA Local 562 broke flanged connections during maintenance, they scraped compressed Garlock and Cranite gaskets from mating surfaces — a process that released concentrated asbestos fiber directly at the worker’s breathing level. UA Local 562 members worked Labadie, Portage des Sioux, the Monsanto chemical complex along the Mississippi River, and industrial facilities throughout the St. Louis metropolitan area on both sides of the river.

Asbestos cloth and blankets

Flexible asbestos cloth manufactured by Johns-Manville was used throughout the facility as protective covering, heat shields, and insulation wrap in areas where rigid insulation could not be applied. Cutting and handling this cloth released fiber readily.

Electrical insulation and fireproofing

Structural fireproofing installed throughout the facility included W.R. Grace Monokote sprayed fireproofing, which contained asbestos in formulations used prior to 1973. Certain electrical applications also used asbestos-containing materials for their combined electrical and thermal insulating properties.

Missouri Asbestos Filing Deadlines: What Labadie Workers Must Know

Missing the Missouri asbestos filing deadline means losing your right to compensation entirely — regardless of how strong your underlying case may be.

Missouri’s Current Five-Year Statute of Limitations

Under Missouri § 516.120 RSMo, the statute of limitations for asbestos personal injury claims is five years from the date of diagnosis — not five years from your last day of exposure, not five years from when symptoms first appeared, and not five years from when you first suspected asbestos was the cause. The clock starts when a physician formally diagnoses you with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease.

HB 68: The Legislative Threat to Your Filing Window

Missouri HB 1664 (2026) is the most significant threat to Missouri asbestos victims’ rights in a generation.

HB 68 passed the Missouri House on March 12, 2026, and is now before the Missouri Senate. If enacted, HB 68 would:

Cut the filing deadline from five years to three years for all new asbestos personal injury claims
Potentially apply retroactively to claims already in progress — the bill’s retroactivity provisions remain in dispute and would almost certainly be litigated if the bill passes
Eliminate filing options for workers who were exposed decades ago and are only now receiving diagnoses, as mesothelioma typically does not appear until 20 to 50 years after first

Litigation Landscape

Coal-fired power plants like Labadie have generated substantial asbestos litigation because boiler systems, turbine insulation, pipe covering, and block insulation products contained asbestos throughout much of the 20th century. Workers at such facilities faced exposure to products manufactured by Johns-Manville, Garlock, Eagle-Picher, Philip Carey, Thermobestos, and Kaylo, among others. These manufacturers supplied thermal insulation, gaskets, packing materials, and boiler components widely used in power generation.

Publicly filed litigation arising from coal-fired power plant exposure has documented claims against major manufacturers and their successor entities. Many of these companies have entered bankruptcy and established asbestos trust funds to compensate injured workers. Relevant trusts include the Johns-Manville Settlement Trust, Eagle-Picher Industries Trust, Garlock Sealing Technologies Trust, and Philip Carey Products Trust. These funds are designed to provide compensation to workers who can establish occupational exposure to the named manufacturer’s asbestos products and a subsequent diagnosis of mesothelioma, asbestos-related lung cancer, or other asbestos-related diseases.

Power plant workers—including boilermakers, insulators, machinists, pipefitters, and maintenance staff—have pursued claims through both traditional litigation and trust fund claims. The nature of work at large industrial facilities like Labadie, where asbestos products were routinely handled, disturbed, and replaced, creates a clear nexus between occupational exposure and disease.

If you worked at the Labadie Power Plant and have been diagnosed with mesothelioma or an asbestos-related condition, you may have rights to compensation.
