About Asbestos Exposure at Aurora BayCare Medical Center — Green Bay, Wisconsin: What Tradesmen and Construction Workers Need to Know
Aurora BayCare Medical Center in Green Bay, Wisconsin is the kind of large-scale healthcare facility where tradesmen and construction workers faced serious, often unrecognized asbestos exposure for decades. Like many Wisconsin hospitals built or substantially renovated during the peak asbestos era — roughly the 1930s through the early 1980s — facilities of this type reportedly relied heavily on asbestos-containing materials throughout their mechanical infrastructure, building envelope, and interior systems.
Hospitals of Aurora BayCare’s era and scale operated complex central mechanical plants requiring extensive high-temperature insulation throughout every system. The boiler room reportedly housed fire-tube or water-tube boilers, operating at extreme pressures and temperatures. Equipment from these manufacturers was routinely insulated at the factory with asbestos rope gaskets, asbestos block insulation, and asbestos-containing refractory cement that reportedly contained chrysotile or amosite asbestos fibers.
From the boiler plant, steam traveled through high-pressure supply mains running through pipe chases, tunnels, mechanical rooms, and ceiling plenums throughout the building. These steam lines reportedly were heavily insulated — wrapped in Thermobestos block insulation or pipe covering, then finished with an outer canvas jacket. Every valve, flange, elbow, and fitting reportedly received its own hand-molded asbestos-containing fittings cover.
The HVAC systems in hospitals of this type reportedly used duct insulation containing asbestos, along with flexible connector boots between air handlers and ductwork that reportedly incorporated asbestos cloth and asbestos-containing adhesives. Mechanical equipment rooms housing pumps, heat exchangers, and condensate return equipment presented additional exposure opportunities for any tradesman entering those spaces, particularly as surrounding materials deteriorated over decades of operation.
General Equipment at Asbestos Exposure at Aurora BayCare Medical Center — Green Bay, Wisconsin: What Tradesmen and Construction Workers Need to Know
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.

Who May Have Been Exposed at Asbestos Exposure at Aurora BayCare Medical Center — Green Bay, Wisconsin: What Tradesmen and Construction Workers Need to Know
Boilermakers, pipefitters, steamfitters, insulators, HVAC mechanics, electricians, and maintenance workers who kept these hospitals running may have encountered asbestos daily. It was in the pipe lagging they handled, the floor tiles they cut and ground, and the spray-on fireproofing that rained down during overhead work.
Wisconsin boilermakers — many of them members of Boilermakers Local 107, which represented workers throughout the Green Bay region and northeastern Wisconsin — are alleged to have worked directly on this equipment during original installation, routine maintenance outages, and emergency repairs. Pipefitters Local 601, which represented steamfitters and pipefitters working throughout Green Bay and the Fox Valley, sent members to hospital construction and maintenance assignments throughout this era. Disturbing deteriorated Thermobestos pipe covering during routine maintenance allegedly released friable asbestos fibers directly into worker breathing zones — the same exposure mechanism documented in trust fund claims filed by former members of Pipefitters Local 601 who worked at Wisconsin industrial and healthcare facilities. IBEW Local 494 electricians who worked alongside pipefitters and insulators in mechanical spaces are alleged to have faced asbestos exposure from both their own conduit work and the concurrent work of other trades.
Boilermakers are documented to have faced heavy exposures in hospital boiler rooms — working directly on boiler shells, replacing asbestos-containing refractory materials, and performing hot work around deteriorating insulation. These workers reportedly cut, shaped, and applied asbestos-containing materials as a core part of daily work. Boilermakers at facilities like Aurora BayCare Medical Center are alleged to have mixed asbestos cement without respiratory protection and entered boiler breechings where asbestos refractory materials lined interior chambers.
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
- 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 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 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.
