About Asbestos Exposure at Crittenton Hospital — Rochester, Michigan: Former Worker Claims
Crittenton Hospital in Rochester, Michigan served Oakland County for decades. Like nearly every major hospital complex built or expanded between 1930 and 1980, its infrastructure was reportedly assembled with asbestos-containing materials running through mechanical systems, structural components, and finishing materials. Boilermakers, pipefitters, insulators, HVAC mechanics, electricians, and general maintenance workers built and maintained this facility. That work may have exposed them to airborne asbestos fibers repeatedly over the course of their careers.
The danger was not in patient corridors. It was in boiler rooms, pipe chases, mechanical spaces, and ceiling plenums — the spaces where tradesmen worked every day. Those workers may have paid for that work with their health.
Large hospital complexes like Crittenton ran central boiler plants generating high-pressure steam for heating, sterilization, and hot water distribution across the entire campus. Boilers manufactured by, and Cleaver-Brooks were routinely packed with thick block and blanket asbestos insulation designed to retain heat and shield workers from thermal burns. The insulation meant to protect workers from burn injuries is alleged to have exposed those same workers to airborne asbestos fibers every time a boiler was repaired, relined, or inspected.
Boilers at facilities of this type are alleged to have relied on Thermobestos block insulation and 85% magnesia asbestos block — materials that required cutting, fitting, and removal during maintenance cycles. Steam lines ran through pipe chases and tunnels connecting the central plant to every wing of the facility. HVAC ductwork and air handling units were reportedly wrapped or lined with asbestos-containing insulation and gasket materials. Structural steel in mechanical rooms was frequently coated with spray-applied fireproofing, a sprayed-on fireproofing compound alleged to have become friable and shed fibers when disturbed or abraded during service work.
General Equipment at Asbestos Exposure at Crittenton Hospital — Rochester, Michigan: Former Worker Claims
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 — Michigan
The records below are verified, state-documented asbestos removals at this facility. Each entry represents a regulated abatement project where the Michigan EGLE (Environment, Great Lakes & Energy) (Michigan EGLE) 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 Michigan EGLE 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 Crittenton Hospital — Rochester, Michigan: Former Worker Claims
Boilermakers — often members of Boilermakers Local 169 — relined, repaired, and inspected boiler fireboxes packed with refractory and Thermobestos insulation. This work is alleged to have involved direct contact with friable products inside confined, poorly ventilated spaces.
Pipefitters and steamfitters — members of Pipefitters Local 636 or Plumbers and Pipefitters UA Local 98 — cut, joined, and removed insulated steam and condensate return lines throughout the facility. Workers are alleged to have used hand tools to cut through calcium silicate pipe insulation, Armstrong Cork, and Thermobestos coverings, generating heavy dust in enclosed spaces.
Heat and frost insulators — members of Asbestos Workers Local 25 — applied, removed, and replaced asbestos pipe covering and block insulation as their primary job function. Co-workers have described these workers as laboring inside visible clouds of asbestos fiber. They are alleged to have carried the highest cumulative exposure levels among hospital trades.
HVAC mechanics serviced air handling units, cut duct insulation, replaced gaskets and packing, and removed or disturbed spray-applied fireproofing during equipment repair.
Electricians worked in mechanical rooms and above suspended ceilings, disturbing spray-applied fireproofing, cutting through transite board, and replacing asbestos-wrapped conduit and equipment insulation.
General maintenance workers and hospital engineers performed daily rounds and work-order repairs throughout areas reportedly containing deteriorating asbestos insulation from Thermobestos, calcium silicate pipe insulation, Armstrong Cork, and other manufacturers.
Bystander exposure was also common. A pipefitter working twenty feet from an insulator stripping pipe covering may have inhaled equivalent fiber concentrations without ever touching the material directly. Multiple trades working simultaneously in confined mechanical spaces are alleged to have created exposures affecting entire crews.
Michigan — Filing Deadline & Next Steps
Michigan law gives mesothelioma and asbestos-disease claimants 3 years from the date of medical diagnosis to file a personal-injury lawsuit (MCL § 600.5805(13)). For wrongful-death claims after an asbestos-related death, the filing window is 3 years from the date of death (MCL § 600.5852). 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 Michigan 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 — Michigan
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.
Cross-State & Regional Corridor Workers
Michigan’s industrial economy made this risk especially acute. Tradesmen in the Detroit metro area and across southeastern Michigan routinely moved between job sites — working at Crittenton Hospital one month, the Ford River Rouge Complex in Dearborn the next, then Chrysler Jefferson Assembly in Detroit, or a GM Hamtramck plant shutdown. Insulators affiliated with Asbestos Workers Local 25, pipefitters from Pipefitters Local 636, and boilermakers from Boilermakers Local 169 built careers rotating among hospitals, auto plants, utilities, and industrial facilities throughout the region. Their cumulative exposure — accumulated across multiple Michigan job sites — is the full picture that asbestos litigation must capture.
Boilermakers who rotated between Crittenton and heavy industrial sites such as Buick City in Flint or Packard Electric in Warren are alleged to have accumulated asbestos exposure across multiple facilities, compounding their overall disease risk.
Local 636 members dispatched from the Detroit area are alleged to have worked at hospitals, auto plants including Ford River Rouge and Chrysler Jefferson Assembly, and utility facilities across southeastern Michigan, carrying cumulative fiber burdens from every site.
Local 25 members working out of the Detroit area are alleged to have rotated through Crittenton Hospital, Packard Electric in Warren, UAW Local 600 facilities in Dearborn, and dozens of other Michigan job sites where the same asbestos insulation products appeared throughout the 1950s, 1960s, and 1970s.
Electricians dispatched to hospital service work through Detroit-area union halls are alleged to have encountered transite board and spray fireproofing at Crittenton and at comparable Michigan facilities throughout their careers.
