About Alcoa Posey County Mt. Vernon Indiana
The Aluminum Company of America (Alcoa) built a major aluminum smelting and reduction facility in Posey County, Indiana, near Mt. Vernon — commonly called Alcoa Warrick Operations or the Alcoa Posey County plant. The facility ranks among Indiana’s largest industrial complexes, positioned along the Ohio River for transportation access, water supply, and the massive power loads that aluminum production demands.
The Alcoa Posey County plant included potrooms (electrolytic reduction cells where molten aluminum was produced), rolling mills and casting operations, boiler houses and steam distribution systems, electrical substations and utility infrastructure, and extensive industrial piping networks for steam, water, and process systems. The facility operated continuously at temperatures exceeding 1,700°F (927°C).
Aluminum smelting via the Hall-Héroult electrolytic reduction process requires sustaining molten aluminum oxide at temperatures exceeding 1,700°F (927°C). Facility engineers in the mid-twentieth century specified asbestos-containing insulation and refractory products because those materials met the thermal demands at a cost no substitute could match. Alternatives simply did not exist at industrial scale until well into the 1970s.
Alcoa’s Warrick facility reportedly began operations in the 1950s and 1960s, when asbestos use in heavy industrial construction was at its peak. During major expansion and peak production in the 1960s–1970s, the use of asbestos-containing materials reportedly remained high. Following the EPA’s initial asbestos regulations in the mid-1970s and OSHA’s successive tightening of asbestos exposure standards beginning in 1971, the Alcoa Posey County facility reportedly began reducing new asbestos-containing material use and implementing abatement programs. Asbestos-containing materials already installed throughout the plant allegedly remained in place well into the 1980s and 1990s.
General Equipment at Alcoa Posey County Mt. Vernon Indiana
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 — Indiana
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Indiana Department of Environmental Management (IDEM) 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.

Who May Have Been Exposed at Alcoa Posey County Mt. Vernon Indiana
Insulators — including members of Heat and Frost Insulators Local 1 who may have worked on contract assignments at this facility — worked at the center of asbestos-containing material use. Their primary function was installing, maintaining, and removing insulation on pipes, boilers, furnaces, and tanks. Workers may have handled asbestos-containing pipe covering, calcium silicate pipe insulation, block insulation, cement, and fitting insulation throughout each shift. Cutting, fitting, and applying these materials — or stripping them during maintenance — reportedly generated substantial concentrations of airborne asbestos fibers.
Pipefitters and steamfitters — including members of Plumbers and Pipefitters UA Local 157 who may have worked on-site — maintained the facility’s steam, water, compressed air, hydraulic, and process piping systems. That work routinely required cutting through or working adjacent to asbestos-containing pipe insulation, handling asbestos-containing gaskets, working with asbestos rope packing, applying asbestos-containing joint compounds and cements, and removing and replacing valve packing, which may have released airborne asbestos fibers.
Boilermakers working on construction, inspection, and overhaul of boilers and pressure vessels may have been exposed to block insulation and castable refractory containing asbestos, asbestos rope gaskets and sheet gaskets sealing boiler doors, asbestos insulating cement, and asbestos boiler blankets and covers. During boiler overhauls — where workers entered the vessel and worked in direct contact with interior refractory and insulation surfaces — exposures to asbestos-containing materials may have reached their highest levels.
Electricians at heavy industrial facilities may have encountered asbestos-containing materials through asbestos-containing electrical panels and switchgear, asbestos-insulated wiring in older electrical systems, and other electrical components.
Indiana — Filing Deadline & Next Steps
Indiana law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (Ind. Code § 34-11-2-4). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (Ind. Code § 34-23-1-1). 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 Indiana 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 — Indiana
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 a claim 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.
Cross-State & Regional Corridor Workers
This facility sits within the same industrial corridor shared by neighboring states along the Ohio River, where comparable operations at comparable regional power stations and comparable regional power stations represent similar occupational asbestos exposure risks.Data Sources — Indiana
