The University of Michigan’s Ann Arbor campus covers over 31 million square feet across hundreds of buildings—research laboratories, hospital complexes, steam tunnels, dormitories, athletic facilities. For the better part of a century, from the 1920s through the 1980s, workers in maintenance, trades, construction, and hospital operations may have been exposed to asbestos-containing materials (ACM) from manufacturers including, /, gaskets and packing, ceiling tile. These materials were allegedly embedded in steam pipes, boilers, fireproofing systems, floor and ceiling tiles, and structural components throughout the campus.
Specific pipe insulation products—including calcium silicate pipe insulation , Thermobestos , and pipe insulation —were reportedly in widespread use across the campus infrastructure.
If you worked at U of M and have since been diagnosed with mesothelioma, asbestosis, lung cancer, or pleural disease, you may have substantial legal rights to compensation. This page explains the scope of alleged asbestos use at this facility and your options for pursuing an asbestos lawsuit in Michigan. Workers and families in Michigan and Illinois should know that plaintiff-friendly venues—including Wayne County Circuit Court, Madison County IL, and St. Clair County IL—may offer significant strategic advantages for your case.
General Equipment at University of Michigan
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
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 University of Michigan
Job Categories at Elevated Risk
Anyone in the following roles who worked at U of M during the relevant era should evaluate their potential exposure history:
- Facilities maintenance and custodial workers performing routine repairs and upkeep
- Union tradespeople—including members of Heat and Frost Insulators Local 1 (St. Louis area), Heat and Frost Insulators Local 27 (Kansas City area), Plumbers and Pipefitters UA Local 562 (St. Louis area), and Plumbers and Pipefitters UA Local 268 (Kansas City area)—working as insulators, pipefitters, boilermakers, electricians, plumbers, carpenters, and laborers on steam systems and building infrastructure
- Construction and demolition contractors on renovation or new-construction projects
- Facilities engineers and mechanical specialists
- University of Michigan Health System employees (now Michigan Medicine): hospital maintenance staff and contractors
- Students and faculty with sustained occupancy in older buildings or research laboratories
- Family members of tradespeople who may have carried asbestos fibers home on clothing, hair, skin, and tools—so-called “take-home” or secondary exposure
Secondary exposure is fully compensable under Michigan law. If your spouse or parent worked at U of M, your diagnosis may be directly traceable to their workplace.
Critical 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
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.
