About Asbestos Exposure at Hurley Medical Center — Flint, Michigan: A Guide for Workers and Tradesmen
Large hospital complexes built or expanded between the 1930s and 1980s ranked among the most asbestos-intensive structures in Michigan’s industrial built environment. Unlike office buildings or schools, hospitals ran continuously — 365 days a year — demanding constant steam heat, reliable hot water, and climate control across sprawling multi-wing facilities. Those systems required vast networks of boilers, insulated pipes, and HVAC ductwork, all routinely packed with asbestos-containing materials sourced from manufacturers who distributed heavily throughout the Great Lakes region.
Michigan’s postwar hospital construction boom coincided precisely with peak asbestos use in the building trades. Facilities that expanded through the 1950s, 1960s, and into the 1970s reportedly incorporated asbestos-containing materials as a matter of standard specification — it was what architects, mechanical engineers, and hospital administrators called for, and it was what Michigan union tradesmen installed. Hurley Medical Center, a large publicly operated facility serving Flint and Genesee County, reportedly relied on exactly these mechanical systems during the decades when asbestos use was at its height.
The boiler room was the heart of Hurley’s heating system. Industrial boilers were routinely insulated with block insulation, pipe covering, and cement products alleged to have contained chrysotile and amosite asbestos. These same boiler manufacturers supplied equipment to Michigan’s auto facilities — Ford River Rouge Complex, Chrysler Jefferson Assembly, and Buick City in Flint — and the insulation products applied to their equipment were drawn from the same regional supply lines that reportedly reached Hurley’s mechanical plant.
Insulated pipes running through pipe chases, tunnels, and mechanical rooms throughout Hurley reportedly were covered with products including Thermobestos pipe insulation and block insulation, calcium silicate pipe insulation block and pipe insulation, and pipe coverings and cork products. Michigan’s steam-heated institutional buildings of this era were particularly asbestos-intensive because of the high operating temperatures involved. Steam distribution systems required thick, multi-layered insulation capable of withstanding sustained heat — conditions that drove the selection of high-asbestos-content products throughout the postwar decades.
General Equipment at Asbestos Exposure at Hurley Medical Center — Flint, Michigan: A Guide for Workers and Tradesmen
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 Hurley Medical Center — Flint, Michigan: A Guide for Workers and Tradesmen
Boilermakers who serviced, rebricked, and repaired Hurley’s central plant are alleged to have worked in direct contact with block insulation, refractory materials, and gasket products on a regular basis. Pulling old Thermobestos and calcium silicate pipe insulation block insulation, handling broken refractory brick, and replacing deteriorating gaskets all allegedly generated heavy asbestos dust in a confined boiler room environment. Many Genesee County boilermakers built careers that moved between Hurley’s mechanical plant, GM Hamtramck, Buick City in Flint, and regional industrial construction projects — accumulating asbestos exposure across multiple sites and employers.
Pipefitters and steamfitters who installed, modified, and maintained Hurley’s steam distribution network reportedly cut, fitted, and removed Thermobestos, calcium silicate pipe insulation, and Armstrong pipe covering throughout their careers at the facility. Heavy dust concentrations allegedly built up in confined pipe chases and mechanical rooms with minimal air movement. Heat-tracing operations, valve replacements, and routine maintenance all involved disturbing pipes that were reportedly covered in asbestos-containing insulation. Pipefitters Local 636, one of Michigan’s major mechanical trade locals, represented members who worked across Flint-area hospital, commercial, and industrial accounts during the peak asbestos era.
The trades who built and maintained Hurley’s systems were organized through Michigan union locals with deep roots in both hospital work and industrial construction — including members of Asbestos Workers Local 25, Pipefitters Local 636, and the broader network of Genesee County building trades locals whose members moved between hospital contracts and the auto industry’s vast mechanical infrastructure.
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
Flint’s industrial heritage — built on auto manufacturing at GM Hamtramck, Buick City, and the surrounding Genesee County supply chain — means the trades who built and maintained Hurley Medical Center often came directly from, or worked alongside, union members from facilities where asbestos use was equally intensive. Many of the same insulators, pipefitters, and boilermakers who worked Hurley’s mechanical plant cycled through GM facilities, Packard Electric in Warren, and regional construction projects across mid-Michigan. Their asbestos exposure did not begin and end at Hurley’s property line — but Hurley’s boiler plant, pipe systems, and mechanical spaces were significant contributors to their cumulative dose.Data Sources — Michigan
