About Asbestos Exposure at Aultman Hospital — Canton, Ohio
Central Boiler Plant — Multi-Boiler Systems
The central boiler facility at Aultman reportedly housed multiple high-pressure boiler units from manufacturers including:
- — insulated with proprietary asbestos block systems
- — generating substantial asbestos insulation tonnage per installation
- — coal and fuel-fired units requiring heavy thermal protection
Boiler shells, fireboxes, steam drums, flues, and headers were reportedly insulated with products including:
- boiler block insulation and asbestos brick mortar compounds
- calcium silicate pipe insulation** — rigid calcium silicate sections with asbestos binders
- Sectional asbestos covering and blanket insulation on associated piping
Maintenance and Repair Work in the Boiler Room
Every retubing job, fireside cleaning, inspection, and repair is alleged to have required workers to disturb, remove, or work directly adjacent to asbestos insulation in poorly ventilated boiler rooms.
Cutting through Thermobestos** blocks with a hacksaw or chipping deteriorated insulation before a repair are documented in Ohio litigation as generating dense asbestos dust in confined spaces. Workers are alleged to have performed this work without respiratory protection or dust controls. Regulated abatement protocols did not exist until after the 1970s, and informal asbestos removal without controls reportedly continued in many Ohio hospital facilities into the 1980s.
Products workers may have handled during boiler maintenance:
- boiler block insulation
- calcium silicate pipe insulation block systems
- gaskets and packing materials
The Steam Distribution Network — Insulated Piping Throughout Campus
From the central plant, steam moved through insulated pipe running through underground utility tunnels, multi-story vertical pipe chases, mechanical rooms, and inter-building connectors in crawl spaces.
Pipe Insulation Products
Steam lines throughout the system were reportedly insulated with:
- Thermobestos** — sectional and molded pipe covering on high-temperature lines
- calcium silicate pipe insulation** — rigid calcium silicate sections on 2-inch through 12-inch diameter piping
- — molded sections with asbestos-containing jackets
- pipe insulation systems
- asbestos-containing insulation products
- gaskets and packing and joint compound
Cutting sections of calcium silicate pipe insulation or Thermobestos with a hacksaw in confined pipe chases is alleged to have generated heavy visible dust. Pipefitters are alleged to have performed this work daily without respiratory protection or dust control.
Valve and Fitting Work
Thousands of valve connections and pipe junctions throughout the steam system reportedly contained asbestos rope packing, gasket material, and fitting insulation. Workers performing routine valve maintenance and packing replacement are alleged to have had direct contact with asbestos fiber at each connection point.
Pulling deteriorated packing from a valve stem and pressing in new asbestos rope is alleged to have produced visible dust. Products involved may have included:
- gaskets and packing asbestos valve stem packing
- asbestos gaskets and joint compounds
- valves and valve packing insulation sleeves and covers
Building Materials Beyond the Mechanical Core
Older wings of Aultman reportedly incorporated asbestos-containing materials throughout the structure:
Ceiling and Floor Tile Systems
- Acoustic ceiling tiles from , ceiling tile, and in administrative and utility areas reportedly contained asbestos-containing materials
- Vinyl-asbestos floor tiles — 9-inch and 12-inch tiles in corridors, utility rooms, and mechanical spaces
- Tile mastic adhesives from and other manufacturers
Spray-Applied Fireproofing
- spray-applied fireproofing** — spray-applied fireproofing on structural steel in mechanical spaces and boiler rooms reportedly contained asbestos in formulations manufactured before 1973
- spray fireproofing compounds
- ceiling tile asbestos-containing fireproofing materials
HVAC Duct Insulation
- calcium silicate pipe insulation** duct wrap and pipe insulation** insulation in systems installed before the 1980s reportedly contained asbestos-containing materials
- Asbestos-containing insulation lining on interior ductwork surfaces
Transite (Asbestos-Cement Board) -, ceiling tile, and transite board reportedly used in mechanical rooms, electrical chases, heat shields, electrical box surrounds, and duct encasement
- Transite partition material between mechanical zones
Transite holds together when intact. Drilling, cutting, or demolishing it does not. Electricians and maintenance workers who drilled through transite board for cable runs reportedly raised visible dust clouds without respiratory protection.
General Equipment at Asbestos Exposure at Aultman Hospital — Canton, Ohio
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 — Ohio
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Ohio Environmental Protection Agency (Ohio EPA) 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 Ohio EPA 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.

Ohio — Filing Deadline & Next Steps
Ohio law gives mesothelioma and asbestos-disease claimants 2 years from the date of medical diagnosis to file a personal-injury lawsuit (ORC § 2305.10). For wrongful-death claims after an asbestos-related death, the filing window is 2 years from the date of death (ORC § 2125.02). 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 Ohio 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 — Ohio
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.
