General Equipment at Western Union
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 — Missouri
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 Western Union
Several crafts may have been exposed to asbestos-containing materials at the Western Union facility, often without protective equipment or warning. The trades below have historically carried the highest documented rates of asbestos-related disease in Missouri power-generation settings.
Heat and Frost Insulators (Heat and Frost Insulators Local 1)
Thermal insulation work placed insulators in direct daily contact with pipe covering, block insulation, and insulating cement. Cutting, fitting, and removing these materials allegedly generated significant airborne asbestos dust. Insulators regularly worked in confined spaces — boiler rooms, turbine halls, subterranean pipe tunnels — where dust concentrations stayed elevated for hours after insulation work ended.
Heat and Frost Insulators Local 1, headquartered in St. Louis and representing insulators across the Missouri side of the Mississippi River industrial corridor, dispatched members to regional power plants, chemical facilities, and industrial complexes throughout this period. Members of Local 1 who rotated between the Western Union facility and comparable sites such as Labadie, Portage des Sioux, and industrial operations along the river may have accumulated exposures across multiple jobsites over the course of a single career.
If you were a member of Local 1 and have received an asbestos-related diagnosis, contact a Missouri asbestos attorney immediately. The 5-year personal injury clock under § 516.120 began running on your diagnosis date — not on the date of your last shift. Every month you wait is a month you will not recover.
Pipefitters and Steamfitters (UA Local 562)
Steam and condensate systems require constant maintenance: replacing gaskets, repacking valves, repairing insulated lines, replacing failed pipe covering sections. Pipefitters allegedly disturbed intact insulation repeatedly throughout their careers, releasing fibers with each work cycle. Emergency repairs and seasonal overhauls were performed under time pressure, routinely without respiratory protection.
UA Local 562 — the United Association local representing plumbers and pipefitters in the St. Louis metropolitan area — dispatched members to power plants, refineries, and industrial facilities throughout Missouri’s river corridor during the peak asbestos-use decades. Members dispatched to the Western Union facility may have previously worked at Labadie, Portage des Sioux, or the heavy industrial sites around Granite City, Illinois.
Boilermakers (Boilermakers Local 27)
Boilermakers who worked on furnaces, pressure vessels, steam drums, and refractory systems may have been exposed to refractory materials and insulating cements during both installation and teardown. Removal of deteriorated refractory linings from boiler interiors — in confined, poorly ventilated spaces — allegedly released high concentrations of dust.
Boilermakers Local 27, the St. Louis-based local representing boilermakers across Missouri and portions of southern Illinois, dispatched members to power generation and industrial facilities throughout this region. Local 27 members who worked construction and maintenance outages at Western Union and then rotated to Labadie, Portage des Sioux, or steel-producing facilities in the Granite City corridor may carry exposure histories spanning multiple decades and multiple facilities.
Electricians (IBEW and Related Locals)
Electrical tradespeople who worked on switchgear, motor controls, turbine generators, and associated wiring may have been exposed to asbestos-containing electrical insulation components. Electricians also worked alongside insulators and pipefitters, and secondary exposure from dust generated by neighboring trades is well-documented in the medical and legal literature.
Maintenance Mechanics and Millwrights
Maintenance personnel and millwrights who serviced pumps, compressors, turbine bearings, and auxiliary equipment may have disturbed gaskets, packing, and insulation during routine repairs — often across decades-long careers at the same facility.
Laborers and Helpers
Laborers who swept, cleaned, hauled materials, or worked near insulation and refractory operations may have been exposed to settled asbestos dust without directly handling the materials themselves. Many worked without respiratory protection or any hazard training whatsoever.
Missouri — 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
- 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 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 — Missouri
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.
