About Asbestos Exposure at St. Mary Medical Center — Hobart, Indiana
Mid-Century Hospitals Ran on Asbestos
St. Mary Medical Center in Hobart belongs to a category of mid-twentieth century institutions built and expanded precisely when asbestos was considered the standard material for industrial construction. A hospital of that scale required:
- Industrial mechanical systems supporting sterilization, laundry, kitchens, and building-wide climate control
- Steam distribution networks operating at 300°F and above
- Central boiler plants housing multiple large-capacity units
- Complex HVAC systems serving clinical and support areas throughout the facility
- Pipe chases, mechanical rooms, and plenums running vertically and horizontally through every wing
Asbestos insulated, protected, and fireproofed every component of those systems. It was inexpensive, effective, and—until the 1970s—its dangers were either unknown to workers or deliberately concealed by manufacturers.
General Equipment at Asbestos Exposure at St. Mary Medical Center — Hobart, Indiana
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 — Indiana
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Indiana Department of Environmental Management (IDEM) 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 IDEM 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 St. Mary Medical Center — Hobart, Indiana
Boilermakers
Boilermakers who installed, repaired, and rebricked boiler units are alleged to have worked in environments saturated with asbestos dust from insulation removal and replacement. Pulling old Thermobestos** or calcium silicate pipe insulation** block insulation off boiler shells, fitting new asbestos-containing covering, and rebricking boiler walls generated airborne fiber concentrations during every overhaul. Boilermakers working or units may have been exposed to asbestos-contaminated scale and oxidation products during steam-side cleaning operations.
Pipefitters and Steamfitters
Pipefitters and steamfitters who built and maintained the steam distribution system are alleged to have routinely:
- Cut and shaped Thermobestos** and calcium silicate pipe insulation** pipe covering to fit around fittings and elbows
- Fitted pre-formed insulation sections from onto new and existing piping
- Wrapped high-temperature lines with asbestos cloth, generating visible dust clouds in enclosed pipe chases
- Pulled and replaced asbestos gaskets and packing at valve connections supplied by gaskets and packing and
- Mixed and applied asbestos cement and rope wrappings on-site for steam system modifications
Members of Boilermakers Local 374 and other Indiana trade unions performing comparable work on hospital steam systems are alleged to have experienced routine occupational exposure to identical materials over the same period.
Heat and Frost Insulators
Heat and frost insulators worked most directly with the asbestos-containing materials themselves. They:
- Mixed asbestos cement coatings and applied them to boiler exteriors and piping
- Sawed Thermobestos** and calcium silicate pipe insulation** block insulation to fit around fittings, transitions, and irregular surfaces
- Wrapped pipe systems throughout the facility using asbestos-saturated fabrics and pre-formed coverings
- Reportedly applied spray-applied fireproofing** spray fireproofing during construction and renovation, releasing large quantities of airborne fibers in enclosed spaces
Heat and Frost Insulators Local 18 members performing work at comparable Indiana facilities have documented substantial exposure across every major asbestos-containing product category.
HVAC Mechanics
HVAC mechanics who serviced air handling equipment and ductwork may have been exposed when:
- Removing and replacing calcium silicate pipe insulation**-insulated duct covers and equipment blankets
- Accessing internal components of insulated air handlers where settled asbestos dust allegedly accumulated over years of operation
- Pulling out worn or damaged ductwork sections and removing transite barriers
- Disturbing pipe insulation** spray insulation during equipment maintenance and modification work in enclosed mechanical spaces
Electricians
Electricians pulling wire through pipe chases, conduit runs, and cable trays reportedly lined with Thermobestos**, calcium silicate pipe insulation**, and Armstrong Cork-wrapped insulation may have been exposed to asbestos fibers during routine work. Electricians drilling, cutting, and penetrating through structural elements reportedly fireproofed with spray-applied fireproofing** may have been exposed to friable asbestos with each hole they cut into a ceiling or equipment bay.
General Maintenance and Facility Workers
Maintenance workers patching, repairing, and responding to emergencies over decades of daily operation may have been exposed without ever knowing what was in the materials they handled. These workers:
- Cleaned mechanical rooms and boiler areas, stirring settled asbestos dust with each pass
- Performed emergency repairs on damaged insulation without respiratory protection
- Pulled and replaced vinyl asbestos floor tiles in maintenance areas
- Worked around deteriorating spray-applied fireproofing** and other spray-applied fireproofing in structural bays
No routine inspection protocols identified asbestos content in the materials these workers handled. Respiratory protection was not standard practice.
Indiana — Filing Deadline & Next Steps
Indiana law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (Ind. Code § 34-11-2-4). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (Ind. Code § 34-23-1-1). 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 Indiana 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 — Indiana
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.
