Asbestos Exposure at St. Clare Hospital — Baraboo, Wisconsin: Legal Guide for Workers and Tradesmen

⚠️ URGENT FILING DEADLINE WARNING — Wisconsin Mesothelioma Lawyer Alert

If you have been diagnosed with mesothelioma, asbestosis, lung cancer, or any other asbestos-related disease after working at St. Clare Hospital, you have exactly three years from your diagnosis date to file a civil lawsuit under Wis. Stat. § 893.54. That deadline does not move. Once it expires, your right to sue in Wisconsin court is permanently extinguished — no matter how strong your case is.

The three-year clock starts running the day a physician diagnoses your condition — not the day you were exposed decades ago. But “three years” is not a comfort. It is a countdown. Asbestos-related diseases advance rapidly, evidence becomes harder to gather as time passes, witnesses become unavailable, and manufacturers continue to deplete the asbestos trust funds that may owe you compensation. Every month you wait is a month your legal options narrow.

Wisconsin workers may pursue both civil lawsuits and asbestos trust fund claims simultaneously. Most asbestos bankruptcy trusts have no hard filing deadline — but their assets are finite and depleting. Workers who delay trust fund claims may receive far less than those who file promptly.

Call an experienced Wisconsin asbestos attorney today. Not next month. Today.

If You Worked at St. Clare Hospital: What You Need to Know Now

Tradesmen who worked at St. Clare Hospital in Baraboo between the 1930s and 1980s — boilermakers, pipefitters, insulators, HVAC mechanics, electricians, maintenance workers — may have been exposed to asbestos. You may not know it yet. Asbestos-related diseases take 20 to 50 years to appear. If you have recently received a diagnosis of mesothelioma, asbestosis, or lung cancer, the work you did decades ago at St. Clare may be the reason.

Wisconsin gives you three years from your diagnosis date to file a civil claim under Wis. Stat. § 893.54. That clock starts running the day a physician diagnoses an asbestos-related condition — not the day you were exposed, and not the day your symptoms began. Under Wisconsin’s discovery rule, the limitations period does not begin at the time of exposure. It begins at diagnosis, recognizing that mesothelioma and asbestosis are latent diseases that cannot be detected until they manifest.

Three years sounds like time. It is not.

Gathering medical records, reconstructing decades-old work histories, identifying responsible manufacturers, and preparing a claim takes months. Workers who wait until year two or year three routinely find themselves in a race against time that diminishes the value of their case — or eliminates their right to pursue it altogether.

Do not assume you have time to wait. An experienced Wisconsin asbestos attorney can begin work immediately. Call today.

Why St. Clare Hospital Reportedly Contained Asbestos-Containing Materials

St. Clare Hospital served Sauk County for decades. Like every hospital built or expanded between the 1930s and 1980s, its mechanical infrastructure reportedly relied extensively on asbestos-containing materials. Manufacturers including Johns-Manville, Owens-Corning, Armstrong Cork, W.R. Grace, and Celotex supplied the pipe insulation, boiler block, floor tile, ceiling tile, spray fireproofing, and duct materials that tradesmen installed, repaired, and tore out throughout the building’s mechanical life.

Hospitals were not simple buildings. They ran 24 hours a day, required uninterrupted steam heat, and housed mechanical systems as complex as those found in Wisconsin’s heavy industrial plants — the kind of central utility infrastructure that characterized facilities like Allen-Bradley in Milwaukee, Allis-Chalmers in West Allis, and Falk Corporation in Milwaukee. That complexity meant more pipe, more insulation, more gaskets, more fireproofing — and more asbestos-containing material throughout every mechanical system in the building.

The same insulation contractors and union tradesmen who worked Wisconsin’s industrial plants routinely worked hospital construction and maintenance contracts. Members of Boilermakers Local 107, Pipefitters Local 601, Asbestos Workers Local 19, and IBEW Local 494 are alleged to have performed work at healthcare facilities throughout the Midwest, carrying their trade-specific exposures from one jobsite to the next.

The Mechanical Systems Where Workers May Have Been Exposed

Boiler Room and Central Plant

The boiler room reportedly housed high-pressure steam boilers manufactured by Combustion Engineering, Cleaver-Brooks, and Foster Wheeler. Boiler drums, headers, and firebox surrounds on equipment of this type are documented in occupational health literature and Wisconsin asbestos litigation records as having been insulated with asbestos block and blanket products — including those manufactured by Johns-Manville — along with refractory materials from Owens-Corning and block insulation from Celotex.

Boiler casings, breechings, and valve flanges are alleged to have been wrapped with Johns-Manville Thermobestos, asbestos cement, and asbestos rope gasket materials at handhole covers and flanged connections. Members of Boilermakers Local 107 — whose jurisdiction covered steam-generating equipment throughout Wisconsin — reportedly performed boiler installation, maintenance, and repair work at hospital facilities across the state, including facilities in the Sauk County region.

Steam Distribution Lines

Steam traveled from the boiler plant through basement tunnels, mechanical rooms, and pipe chases to reach every wing of the building. Those distribution lines were reportedly insulated with pre-formed pipe covering products, including:

Johns-Manville Thermobestos
Owens-Corning Kaylo
Carey asbestos pipe insulation
Armstrong World Industries asbestos duct wrap

Thermobestos and Kaylo appear consistently in occupational health literature and in Wisconsin asbestos litigation records as major sources of pipefitter and steamfitter exposure. Both product lines are well-documented in claims filed in Milwaukee County Circuit Court and Dane County Circuit Court, the two primary Wisconsin venues for asbestos personal injury litigation.

Members of Pipefitters Local 601, whose jurisdiction covered steam and process piping throughout south-central Wisconsin, are alleged to have installed and repaired these materials at hospital and institutional facilities throughout the region. Workers who performed maintenance or renovation on these systems may have developed mesothelioma or asbestosis decades after that exposure.

HVAC Systems and Ductwork

Ductwork in facilities of this era was reportedly internally lined with asbestos-containing insulation and sealed at joints with products from Johns-Manville — including asbestos cloth tape and mastic compounds — and W.R. Grace duct sealants and joint compounds.

Air handling units reportedly sat on vibration isolation pads containing compressed asbestos sheet manufactured by Garlock Sealing Technologies or Armstrong World Industries. At every point where steam met air — in heating coils, humidifiers, and unit ventilators — asbestos gaskets and packing materials from Crane Co. and Garlock were reportedly the industry standard.

Electricians working in mechanical spaces alongside HVAC equipment are alleged to include members of IBEW Local 494, which represented electrical workers throughout the Milwaukee area and on regional construction projects. HVAC mechanics and other building trades workers who regularly occupied mechanical spaces may have faced ongoing exposure risk throughout the facility’s operational life.

Pipe Chases and Confined-Space Exposure

Pipe chases running vertically through multi-story hospital buildings concentrated these hazards. Workers entering confined chase spaces to replace valve packing manufactured by Garlock or Crane Co., or to re-insulate sections covered with Johns-Manville Thermobestos or Owens-Corning Kaylo, may have encountered years of accumulated asbestos debris in an enclosed space with no ventilation.

Members of Pipefitters Local 601 and Asbestos Workers Local 19 who performed this type of confined-space work at Wisconsin hospital facilities are alleged to have faced some of the most concentrated fiber exposures documented in occupational health records from this era. Asbestos Workers Local 19 — the Milwaukee-based local of the Heat and Frost Insulators — had jurisdiction over insulation work at institutional and commercial jobsites throughout Wisconsin, and its members reportedly worked alongside pipefitters and boilermakers on hospital mechanical systems across the state.

Asbestos-Containing Materials Reportedly Used at Facilities of This Type

Hospital buildings of St. Clare’s construction period reportedly contained multiple categories of asbestos-containing products:

Thermal pipe insulation on steam and hot water lines: Johns-Manville Thermobestos, Owens-Corning Kaylo, Carey, and Celotex
Boiler block insulation and refractory cement on casings and breechings: Johns-Manville, Owens-Corning, and Celotex asbestos block
Floor tiles and mastic adhesives in service corridors, utility rooms, and maintenance wings: Armstrong Cork and Congoleum tile, with adhesives from W.R. Grace
Ceiling tiles in mechanical spaces and older wings: Armstrong World Industries, Georgia-Pacific, and Johns-Manville
Spray-applied fireproofing on structural steel in mechanical penthouses and boiler rooms: W.R. Grace Monokote and Combustion Engineering Sprayed Fibrous Insulation
Asbestos transite board as fire barriers around boilers, ductwork penetrations, and electrical panels: Johns-Manville and Celotex
Rope gaskets and sheet packing at valve flanges and boiler handhole covers: Crane Co., Garlock Sealing Technologies, and Armstrong Cork
Duct insulation wrap and exterior duct coating: Owens-Corning and Johns-Manville

Why Renovation Work Carried the Highest Risk

Asbestos-containing insulation deteriorates. By the time renovation crews worked in older hospital wings during the 1970s and 1980s, Johns-Manville Thermobestos, Owens-Corning Kaylo, W.R. Grace Monokote, and transite board had reportedly been in place for decades. Friable, crumbling insulation releases airborne fiber at concentrations that may have far exceeded any safe threshold.

Contractors performing tear-out work at St. Clare during this period may have done so without containment or respiratory protection. This pattern is consistent with what Wisconsin asbestos litigation records reflect across the state — tradesmen working in older hospital and institutional buildings during renovation projects routinely disturbed decades-old friable insulation without the benefit of modern abatement protocols, which did not become widely enforced until the mid-1980s.

The Trades at Highest Risk

Boilermakers

Boilermakers reportedly worked directly on boiler casings and fireboxes allegedly insulated with Johns-Manville, Owens-Corning, and Celotex asbestos block and blanket. Removing that insulation during annual outages to access Combustion Engineering or Cleaver-Brooks equipment may have generated concentrated asbestos dust in an enclosed mechanical space. Members of Boilermakers Local 107 who worked hospital and institutional boiler plants across Wisconsin may have faced some of the most direct exposures among Wisconsin tradesmen. Boilermakers are documented in occupational health literature as carrying among the highest rates of mesothelioma of any skilled trade.

If you are a boilermaker — or the family member of a boilermaker — who has been diagnosed with an asbestos-related disease, the three-year deadline under Wis. Stat. § 893.54 is already running. Call an experienced Wisconsin asbestos attorney today.

Pipefitters and Steamfitters

Pipefitters and steamfitters are alleged to have cut, fitted, and installed pre-formed pipe covering from Johns-Manville Thermobestos, Owens-Corning Kaylo, and Carey on steam and condensate return lines throughout the building. Sawing through Thermobestos or Kaylo without respiratory protection — standard practice before the mid-1970s — may have released concentrated asbestos fiber. Members of Pipefitters Local 601 who worked Wisconsin hospital and institutional projects are alleged to have encountered these materials on virtually every job in the region
