If You Worked at MichCon in Detroit and Have Been Diagnosed with Mesothelioma or Asbestosis

If you spent years maintaining, repairing, or operating the natural gas infrastructure that kept Detroit running, you may have been exposed to asbestos-containing materials. Michigan Consolidated Gas Company — known for generations as “MichCon” — reportedly operated compressor stations, boiler systems, and repair facilities throughout Detroit where asbestos-containing materials were allegedly used extensively during the mid-twentieth century.

For workers in skilled trades — insulation, pipefitting, boilermaking, and electrical work — that exposure may have occurred repeatedly over decades. Asbestos fibers that enter the lungs remain there permanently. If you or a family member has developed mesothelioma, asbestosis, or lung cancer after working at MichCon, there is very likely a legal path to compensation from the manufacturers that sold and profited from these materials.

This page covers what happened at MichCon, which trades faced the greatest exposure risk, and what legal options may be available to you right now.

What Was Michigan Consolidated Gas Company and Where Did Exposure Occur?

Operations and Scale

Michigan Consolidated Gas Company emerged in the early twentieth century as Detroit’s dominant natural gas distribution utility. By mid-century, MichCon operated one of the most complex industrial infrastructure networks in the region:

Distribution and compressor stations throughout the Detroit metropolitan area
High-pressure gas storage and processing facilities
Maintenance and service yards where equipment was serviced and refurbished
Downtown Detroit office and administrative buildings
Extensive pipeline networks throughout the city
Riverfront and subsidiary service centers handling equipment repair and overhaul

These operations required large, skilled workforces — insulators, pipefitters, boilermakers, electricians, and laborers — who built, maintained, and operated this infrastructure continuously from the postwar era through the 1980s and beyond.

Corporate History: From Independent Utility to DTE Energy

MichCon operated as an independent utility through much of the twentieth century. MCN Energy Group acquired it in the 1990s. DTE Energy absorbed the company in 2001. This corporate lineage matters for litigation — successor liability, indemnification agreements, and insurance coverage all affect which entities can be named as defendants or sources of compensation. An experienced mesothelioma attorney will know how to trace that chain.

Why Asbestos-Containing Materials Were Reportedly Used Extensively at MichCon

The Thermal Insulation Imperative in Gas Utility Operations

Natural gas distribution and processing involves extreme temperatures, high-pressure steam systems, and combustion equipment. From the 1930s through the mid-1970s, asbestos-containing materials were the industrial insulation standard because they:

Remained stable at temperatures exceeding 1,000°F
Reduced heat loss from pipes and equipment
Met industrial fire safety requirements of the era
Were cheap and universally available from manufacturers including Johns-Manville, Owens-Illinois, Armstrong World Industries, and others
Withstood the mechanical stresses of industrial environments

At MichCon’s facilities, these properties made asbestos-containing materials reportedly ubiquitous in pipes carrying hot gas or steam, compressor housings, boiler systems, turbines, heat exchangers, and related equipment.

Steam, Heating, and Boiler Systems

MichCon’s Detroit operations reportedly included boilers and steam heating systems — standard components in large industrial facilities of the mid-twentieth century. Workers insulating and maintaining these systems may have been exposed to:

Pipe covering manufactured by Johns-Manville and Owens-Illinois, allegedly containing chrysotile and/or amosite asbestos fibers
Block insulation and magnesia products from major manufacturers allegedly incorporating asbestos-containing materials
Asbestos-containing finishing cement used to seal and coat insulation systems

Gaskets, Packing, and Sealing Materials

Asbestos-containing materials were allegedly standard components throughout MichCon’s pressurized piping systems:

Gaskets manufactured by Garlock Sealing Technologies and other suppliers in flanged pipe connections, valve bonnets, and heat exchanger covers — products that may have contained compressed asbestos fibers
Packing materials in pump stuffing boxes and valve stems, many reportedly manufactured to include asbestos-containing materials
Rope and tape produced by Johns-Manville and other manufacturers, used to seal connections and wrap fittings

These products were present in virtually every facility maintaining pressurized systems during the mid-twentieth century.

Fireproofing and Building Materials

MichCon’s Detroit facilities reportedly included structures built or renovated during decades when asbestos-containing building materials were standard in commercial and industrial construction. Workers in these buildings may have been exposed to asbestos-containing products from Armstrong World Industries, Georgia-Pacific, Celotex, and other manufacturers, including:

Spray-applied fireproofing on structural steel — products manufactured by W.R. Grace and others, many reportedly containing amosite or chrysotile asbestos-containing materials
Joint compounds and finishing materials allegedly containing asbestos
Floor tiles and floor tile adhesive allegedly containing chrysotile asbestos
Ceiling tiles with reported asbestos content from multiple suppliers
Roofing materials including built-up roofing felt and coatings
Transite panels and pipe manufactured by Johns-Manville — cement-asbestos products used in walls, partition systems, and piping applications
Plaster in wall and ceiling systems allegedly incorporating asbestos-containing materials

The Regulatory Timeline: Why Exposure Risk Persisted for Decades

Workers at MichCon may have been exposed to asbestos-containing materials for decades before meaningful protective regulations existed. Major manufacturers including Johns-Manville, Owens-Illinois, Crane Co., and others allegedly knew about the dangers of asbestos exposure long before regulatory action was taken:

1930s–1940s: Internal industry studies documented lethal effects of asbestos exposure
1964: Dr. Irving Selikoff’s landmark study documented dramatically elevated cancer rates among asbestos insulation workers
1971: OSHA established the first federal asbestos permissible exposure limits
1973: EPA banned spray-applied asbestos fireproofing
1978: OSHA substantially tightened asbestos exposure limits
1986: OSHA issued its Asbestos Standard for General Industry
1989: EPA attempted a comprehensive asbestos ban, later partially overturned by the Fifth Circuit

This timeline is central to liability. Manufacturers sold asbestos-containing products they allegedly knew were dangerous — and because asbestos-containing materials installed decades earlier often remained in place, workers faced continued exposure during maintenance and renovation work well into the 1980s and beyond.

Which Workers Faced the Greatest Asbestos Exposure Risk at MichCon

Exposure at facilities like MichCon was not limited to one trade. Multiple occupations faced direct exposure risk because asbestos-containing materials were built into nearly every system these workers touched.

Insulators: Highest-Risk Trade

Insulators who may have worked at MichCon — including members of Heat and Frost Insulators unions — likely faced the most direct and intense exposures of any trade on site. These workers applied, maintained, and removed thermal insulation from pipes, boilers, turbines, compressors, and related equipment.

Insulation work at MichCon allegedly involved:

Mixing asbestos-containing insulating cements and muds by hand, generating substantial airborne fiber concentrations
Cutting and fitting asbestos-containing pipe covering — products including Kaylo (manufactured by Owens-Illinois and later Owens Corning), Unibestos (manufactured by Johns-Manville), and Armstrong insulation products allegedly containing chrysotile and/or amosite asbestos-containing materials
Applying asbestos-containing block insulation to boiler surfaces and equipment housings
Removing old, deteriorated asbestos-containing insulation — occupational health experts consistently identify this as the most hazardous task, because aged friable insulation releases large quantities of respirable fibers

Former insulators who may have worked at MichCon and also worked at power plants and other industrial sites throughout Michigan, Missouri, and Illinois may have accumulated significant total asbestos fiber burdens over the course of their careers.

Pipefitters and Steamfitters: Substantial Exposure Risk

Pipefitters and steamfitters at MichCon may have been exposed through multiple pathways:

Cutting and fitting asbestos-containing pipe covering during installation or modification of insulated piping systems
Handling and cutting asbestos-containing gaskets from manufacturers including Garlock Sealing Technologies when breaking pipe flanges, valve connections, and heat exchanger covers
Working in proximity to insulators during insulation application or removal — occupational health research documents significant fiber concentrations from this bystander exposure alone
Removing and replacing valve packing allegedly containing asbestos fibers, in products that may have been manufactured by Crane Co. and other valve suppliers
Working in confined spaces where airborne asbestos-containing fiber concentrations accumulate without dissipation

Boilermakers: Direct Contact with Asbestos-Containing Materials

Boilermakers at MichCon’s boiler and steam systems may have been exposed through:

Removing and replacing rope gaskets and refractory materials in boiler doors, inspection ports, and access panels — many allegedly containing asbestos fibers
Working with boiler blankets and furnace insulation products from manufacturers including Thermobestos that may have contained asbestos-containing materials
Disturbing spray-applied fireproofing and block insulation during boiler maintenance and overhaul — products from W.R. Grace and Armstrong World Industries that allegedly contained amosite or chrysotile asbestos-containing materials
Handling boiler refractory cement and castable products that may have incorporated asbestos
Working alongside insulators during boiler outages and maintenance shutdowns when multiple trades operated simultaneously in the same confined space

Electricians: Frequently Overlooked Exposure Pathways

Electricians at MichCon facilities may have encountered asbestos-containing materials through pathways workers rarely recognized at the time:

Electrical arc chutes and panel components in older switchgear reportedly containing asbestos-containing materials
Wire and cable insulation in older electrical systems potentially incorporating asbestos from manufacturers including General Electric and other suppliers
Electrical conduit fittings and junction boxes with asbestos-containing components, particularly in pre-1970s equipment
Drilling and cutting through asbestos-containing floor tile, ceiling tiles, and Transite walls during electrical installation and modification
Bystander exposure during maintenance shutdowns when insulators and other workers disturbed asbestos-containing materials in the immediate work area

Millwrights and Maintenance Workers: Widespread Exposure Potential

General maintenance workers and millwrights at MichCon may have encountered asbestos-containing materials across the facility through:

Compressor maintenance involving asbestos-containing gaskets and seals from Garlock and other manufacturers
General facility maintenance in buildings with asbestos-containing flooring, ceiling tiles, and wall materials
Repair of heating and ventilation systems with asbestos-containing insulation from Johns-Manville, Owens-Illinois, and related manufacturers

The maintenance worker who spent thirty years doing a little of everything at a MichCon facility may have accumulated exposures from a dozen different asbestos-containing product lines — and may have legitimate claims against multiple defendant manufacturers.
