About Chromalloy Gas Turbine St. Louis Missouri

Chromalloy Gas Turbine Corporation repairs, overhauls, and manufactures gas turbine engine components for the aerospace and power generation industries. Work performed at the St. Louis facility included engines and components for military aircraft (General Electric J79, Pratt & Whitney JT3D and JT4D, Rolls-Royce Spey), commercial aviation (Pratt & Whitney JT8D, General Electric CF6 and CFM56), and industrial power generation turbines supplied to Labadie Energy Center (Franklin County — Ameren UE), Portage des Sioux Power Plant (St. Charles County — Ameren UE), and Rush Island Energy Center (Jefferson County — Ameren UE).

Workers at Chromalloy’s St. Louis location performed disassembly of gas turbine engines and components, cleaning, inspection, and repair using compressed air and abrasive blasting, coating and surface treatment using spray fireproofing thermal barrier coatings, and reassembly using pipe covering and insulation, spiral-wound gaskets, gaskets and packing, Blue-Gard gaskets, and packing materials. Turbine overhaul means stripping engines down to bare metal — pulling thermal insulation and gaskets that were manufactured with asbestos compounds. Military and industrial turbines built before the mid-1980s used calcium silicate insulation, pipe covering, pipe insulation, pipe and block insulation, and block insulation throughout their assemblies. Teardown generates the highest concentrations of airborne asbestos fibers because workers are disturbing aged, friable insulation that has been locked inside operating engines for years.

General Equipment at Chromalloy Gas Turbine St. Louis Missouri

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 Chromalloy Gas Turbine St. Louis Missouri

Asbestos exposure at Chromalloy was not confined to a single trade. Exposure spread across multiple crafts, and many workers who never directly handled asbestos-containing materials inhaled fibers generated by colleagues working nearby — what occupational medicine calls bystander exposure. Missouri courts recognize bystander exposure claims.

Insulators and insulation workers carried the highest documented risk through direct removal and installation of asbestos insulation, including stripping aged calcium silicate insulation, pipe covering, pipe insulation, and pipe and block insulation pipe covering from turbine test cells and support systems; pulling block insulation insulation blankets from turbine casings; cutting and fitting pipe covering and insulation and insulation board and block; mixing and applying asbestos-containing insulating cement; and removing and replacing asbestos thermal insulation on turbine casings and piping systems serving Labadie Energy Center and Rush Island Energy Center turbines. Heat and Frost Insulators Local 1, St. Louis, MO represented these workers. Plumbers and Pipefitters UA Local 562 (St. Louis) members removed gaskets and packing and pipe covering and insulation gaskets without adequate respiratory protection despite documented dangers.

Critical Filing Deadline & Next Steps

Missouri law gives mesothelioma and asbestos-disease claimants 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). 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

  1. 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.
  2. Preserve medical records. Pathology reports, biopsy results, imaging, and pulmonary-function tests are central to both civil claims and trust-fund filings.
  3. 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.
  4. Speak with an asbestos attorney with Missouri 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

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.
