Asbestos Exposure at Hurley Medical Center — Flint, Michigan: A Guide for Workers and Tradesmen

⚠️ CRITICAL FILING DEADLINE WARNING

If you have been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer, Michigan law gives you exactly three years from your diagnosis date to file a civil lawsuit under MCL § 600.5805(2). Not three years from your last day of work. Not three years from when you first noticed symptoms. Three years from the date of your diagnosis — and that deadline will not be extended.

If you miss that window, you permanently lose your right to pursue compensation in Michigan civil court, regardless of how strong your case is.

Asbestos bankruptcy trust fund claims operate under different rules — most trusts do not impose a strict filing deadline — but trust fund assets are being depleted by the thousands of claims filed every year. Workers who delay filing trust claims risk receiving reduced payments as trust funds pay out at declining rates over time.

Michigan law also allows you to pursue asbestos trust fund claims and civil lawsuits simultaneously. You do not have to choose one path over the other. An experienced asbestos attorney can pursue both on your behalf at the same time — maximizing your potential recovery while protecting your right to compensation.

Call today. Every day you wait is a day closer to losing your right to file.

Your Three-Year Window to Act

You kept Hurley Medical Center running. As a boilermaker, pipefitter, insulator, electrician, or maintenance worker, you may have spent years — or decades — inside one of Flint’s largest employers, keeping boilers fired, steam pipes flowing, and mechanical systems operating around the clock. What you likely didn’t know then is that those same systems were lined, wrapped, and insulated with asbestos-containing materials that may have released dangerous fibers into the air you breathed.

If you’ve been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer, a Michigan mesothelioma lawyer can help you understand your rights. Michigan law gives you three years from your diagnosis date to file a claim under MCL § 600.5805(2). That clock started running on the day your doctor delivered that diagnosis — and it has not stopped since. There is no grace period. There is no exception for workers who didn’t know they had been exposed. The three-year deadline is absolute, and when it expires, so does your legal right to seek compensation in Michigan civil court.

Do not assume you have time to decide later. Workers diagnosed months ago may already be well into their filing window without realizing it. The sooner you contact a Michigan asbestos attorney, the more options remain open to you — including the simultaneous pursuit of civil litigation and asbestos trust fund claims, a strategy Michigan law expressly permits and that experienced asbestos attorneys use to maximize their clients’ recoveries.

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.

Asbestos in Hospital Mechanical Systems

Why Michigan Hospitals Were Asbestos Hotspots

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.

Asbestos exposure in Michigan institutional settings followed predictable patterns based on facility design and maintenance operations. 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.

The Central Boiler Plant

The boiler room was the heart of Hurley’s heating system and the site of some of the most significant asbestos exposure risk for tradesmen who worked there. Industrial boilers manufactured by companies including Combustion Engineering, Babcock & Wilcox, and Foster Wheeler 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.

Every time a boiler was rebricked, a gasket replaced, or a section of pipe covering pulled for repair, friable asbestos fibers were allegedly released into the air of an enclosed boiler room with limited ventilation. Occupational health literature documents boiler room insulation and refractory materials as major sources of airborne fiber release, and asbestos litigation in Wayne County has produced extensive testimony from Genesee County boilermakers describing exactly these conditions in institutional settings comparable to Hurley.

Steam Distribution Piping

Insulated pipes running through pipe chases, tunnels, and mechanical rooms throughout Hurley reportedly were covered with products including:

Johns-Manville Thermobestos pipe insulation and block insulation
Owens-Corning Kaylo block and pipe insulation
Armstrong World Industries pipe coverings and cork products

Thermobestos and Kaylo appear repeatedly in occupational health literature and Michigan asbestos litigation — including cases filed in Wayne County Circuit Court and Ingham County Circuit Court — as documented sources of airborne asbestos fiber in hospital and industrial settings across the state. Workers cutting, fitting, or disturbing this pipe covering are alleged to have encountered dangerous concentrations of respirable fibers during routine maintenance, modifications, and emergency repairs.

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 from Johns-Manville and Owens-Corning throughout the postwar decades.

HVAC Systems, Transite Board, and Spray-Applied Fireproofing

Asbestos reportedly ran through Hurley’s mechanical infrastructure well beyond the boiler plant:

HVAC ductwork was commonly lined or insulated with asbestos-containing materials from Georgia-Pacific and Celotex, both of which distributed extensively through Michigan building supply channels
Transite board — an asbestos-cement product manufactured by Crane Co. — was reportedly used on equipment pads, fire barriers, and chase walls throughout the facility
Spray-applied fireproofing, including W.R. Grace Monokote, is alleged to have been applied to structural steel during construction and expansion phases from the 1950s through the 1970s

W.R. Grace Monokote was applied by tradesmen throughout Michigan’s postwar construction boom, including on hospital expansions across Genesee, Ingham, Wayne, and Oakland Counties. These materials shed fibers when disturbed by overhead work, renovation activity, or routine maintenance operations conducted in the spaces below.

Asbestos-Containing Materials Reportedly Present at Hurley Medical Center

Based on construction methods, mechanical specifications, and materials supply patterns common to Michigan hospitals built during Hurley’s era, the following materials may have been present throughout the facility:

Boiler Room and Steam Systems:

Block insulation on boiler shells (Johns-Manville, Owens-Corning)
Pipe and boiler insulation (Thermobestos, Kaylo, Armstrong)
Asbestos rope, cloth, and gasket materials (Eagle-Picher, Garlock Sealing Technologies)
Boiler refractory cement and fire brick

Eagle-Picher and Garlock gasket and packing products were widely distributed to Michigan industrial and institutional accounts throughout the asbestos era. Both manufacturers face extensive legacy litigation in Michigan courts, including claims filed by Genesee County tradesmen.

Building Finishes:

9-inch and 12-inch vinyl asbestos floor tiles in corridors, service areas, and mechanical spaces (Armstrong World Industries, Pabco, Georgia-Pacific)
Mastic and adhesive beneath floor tiles
Acoustical ceiling tiles in corridors, offices, and mechanical spaces (National Gypsum Gold Bond and Sheetrock brands)

Mechanical Systems:

HVAC duct insulation and liners (Owens-Corning, Georgia-Pacific)
Transite board panels and fire barriers in mechanical rooms (Crane Co.)
Spray-applied fireproofing on structural steel (W.R. Grace Monokote)

High-Temperature Applications:

Joint compounds and sealants (Armstrong World Industries, National Gypsum)
Chilled water, hot water, and steam line insulation (Johns-Manville, Owens-Corning)

Workers who may have disturbed any of these materials during renovation, demolition, or maintenance are alleged to have encountered asbestos in friable condition — the form that generates the highest fiber concentrations in breathing zones. Michigan courts have recognized all of these product categories as potential exposure sources in asbestos personal injury litigation.

Which Trades Faced the Heaviest Exposure

Boilermakers

Boilermakers who serviced, rebricked, and repaired Hurley’s central plant are alleged to have worked in direct contact with Johns-Manville and Owens-Corning block insulation, refractory materials, and gasket products from Eagle-Picher and Garlock on a regular basis. Pulling old Thermobestos and Kaylo 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 before a single mesothelioma diagnosis decades later. Michigan mesothelioma settlement patterns reflect this multi-site exposure history, and experienced asbestos attorneys account for it when building a recovery strategy.

If you worked as a boilermaker at Hurley Medical Center and have since been diagnosed with mesothelioma or another asbestos-related disease, the three-year filing deadline under MCL § 600.5805(2) is counting down from the date of that diagnosis. Do not wait to speak with a Michigan asbestos attorney.

Pipefitters and Steamfitters

Pipefitters and steamfitters who installed, modified, and maintained Hurley’s steam distribution network reportedly cut, fitted, and removed Johns-Manville Thermobestos, Owens-Corning Kaylo, 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. Members of Local 636 who worked Hurley’s mechanical plant may have encountered asbestos-containing materials as a routine part of every shift — not as an occasional hazard,
