About Diesel Generators Power Station

Diesel generator power stations use large industrial diesel-powered generators to produce electricity for municipal, commercial, or institutional use. In Madison and Dane County, these facilities served: standby and emergency power for hospitals, government buildings, and university facilities; primary power generation for industrial operations running independently from the main grid; peaking power support during high-demand periods; and military and civil defense standby power during and after World War II.

The asbestos-containing materials allegedly used in these facilities were frequently manufactured by companies headquartered along the Great Lakes industrial corridor — including facilities in Milwaukee, the regional industrial corridor, and the Metro East Illinois region — linking Madison-area workers to the broader Midwestern industrial supply chain that has been at the center of asbestos litigation for decades.

Skilled trades workers maintained these facilities, many under union agreements with: International Brotherhood of Electrical Workers (IBEW); Heat and Frost Insulators Local 1; Plumbers and Pipefitters UA Local 75; and Boilermakers Local 107 and Local 27 (Madison) who worked at diesel generator facilities — including on Wisconsin jobsites covered under Midwest regional agreements — faced the most direct and sustained contact with asbestos-containing materials. Their work routinely involved: applying asbestos-containing pipe covering to steam and hot water lines — products, and ceiling tile that were mixed, cut, and fitted by hand in enclosed generator rooms; removing and replacing deteriorated asbestos-containing insulation during overhaul and repair cycles; fabricating custom asbestos-containing insulation blankets and lagging for irregular equipment configurations; and working in confined spaces with inadequate ventilation while cutting, shaping, and fitting asbestos-containing materials. Insulators who mixed asbestos-containing cements and applied pipe covering by hand were working in conditions that may have generated asbestos fiber concentrations far exceeding any safe exposure threshold.

Installers, maintainers, and repairers at University of Wisconsin–Madison, state government facilities in Wisconsin, hospitals and medical facilities in Dane County, and various industrial operations throughout Madison and the surrounding area may have been exposed to asbestos-containing materials during the course of routine work on diesel backup power systems.

General Equipment at Diesel Generators Power Station

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 — Wisconsin

The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Wisconsin Department of Natural Resources (Wisconsin 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 Wisconsin 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.

Wisconsin — Filing Deadline & Next Steps

Wisconsin law gives mesothelioma and asbestos-disease claimants 3 years from the date of medical diagnosis to file a personal-injury lawsuit (Wis. Stat. § 893.54). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (Wis. Stat. § 893.54). 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 Wisconsin 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 — Wisconsin

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

The asbestos-containing materials allegedly used in these facilities were frequently manufactured by companies headquartered along the Great Lakes industrial corridor — including facilities in Milwaukee, the regional industrial corridor, and the Metro East Illinois region — linking Madison-area workers to the broader Midwestern industrial supply chain that has been at the center of asbestos litigation for decades. Skilled trades workers maintained these facilities under union agreements, with Heat and Frost Insulators Local 1 — whose members worked across the Great Lakes industrial corridor on power generation and industrial maintenance. Many of the contractors and subcontractors on these projects allegedly sourced materials through Milwaukee-area distributors connected to the Great Lakes industrial corridor.
