For Workers, Families, and Former Employees Facing Mesothelioma or Asbestosis

If you worked at Holley Carburetor or Muncie Manufacturing in Delaware County and have been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer, you may have legal rights to compensation. An experienced mesothelioma lawyer in Indiana can help you navigate the filing process before Indiana’s two-year statute of limitations expires.

⚠️ CRITICAL INDIANA FILING DEADLINE: Your Two-Year Window Is Already Running

Indiana law gives mesothelioma and asbestosis victims only TWO YEARS from the date of diagnosis to file a lawsuit — not from the date of exposure. Under Ind. Code § 34-20-3-1, the moment you or a family member receives a diagnosis of mesothelioma, asbestosis, or asbestos-related lung cancer, that clock starts. Missing this deadline permanently bars your right to compensation through the Indiana court system — no exceptions, no extensions.

Do not wait. Building an asbestos case requires months of preparation:

Identifying every facility where you may have been exposed
Locating product records and safety documentation
Obtaining union apprenticeship records and employment verification
Establishing medical causation and documenting your diagnosis timeline
Interviewing coworkers and former supervisors

Every week you delay is a week your legal team cannot recover. An experienced asbestos attorney in Indiana needs adequate time to build these claims properly — time the statute is already consuming.

Asbestos Trust Fund Claims

Asbestos bankruptcy trust fund claims may be available simultaneously with a civil lawsuit. Most trusts do not impose strict filing deadlines, but trust assets are finite and deplete continuously as claims are paid. Workers and families who file sooner receive more. That is not a sales pitch — it is how trust fund administration works.

Call an Indiana mesothelioma attorney today — not next month, not after another medical appointment. Your diagnosis date triggered the two-year countdown under Indiana law.

If You Worked at Muncie Industrial Facilities, Read This

Muncie built careers on auto parts manufacturing. Holley Carburetor and Muncie Manufacturing employed hundreds of Delaware County residents — pipefitters, boilermakers, insulators, millwrights — who fabricated carburetor assemblies, machined drivetrain components, and kept American automakers running.

The pipe insulation lagging steam lines, the block insulation packed around boilers, the gaskets inside casting equipment — these materials may have contained asbestos-containing materials. Workers may have inhaled fibers daily for years without warnings, protective equipment, or medical monitoring. Decades later, former employees and their family members have reportedly been diagnosed with mesothelioma, asbestosis, and lung cancer — diseases that take 20 to 50 years to develop after initial exposure.

If that describes you or someone in your family, you have legal rights under Indiana law — but those rights expire. Indiana’s two-year statute of limitations under Ind. Code § 34-20-3-1 begins the day you receive your diagnosis. Contact an asbestos attorney in Indiana immediately.

Facility History: Holley Carburetor and Muncie Manufacturing in Delaware County

Muncie’s Place in American Manufacturing

Sociologists Robert and Helen Lynd chose Muncie as the subject of their landmark “Middletown” studies in the 1920s and 1930s precisely because the city embodied American industrial life. Its skilled labor force, rail connections, and proximity to Detroit made it a natural home for automotive supply operations.

Muncie’s industrial identity was part of a broader Indiana manufacturing corridor stretching from the Lake County steel mills in Gary and East Chicago — where U.S. Steel Gary Works, Bethlehem Steel Burns Harbor, and Inland Steel East Chicago employed tens of thousands — through Fort Wayne’s electrical manufacturing plants, through the Muncie and Anderson automotive supply belt, and south to Cummins Engine’s Columbus operations.

Workers who moved through this corridor accumulated asbestos exposure at multiple facilities over the course of a career. The asbestos-containing materials present across these plants came from many of the same suppliers and were installed by many of the same union contractors. A worker who began at Holley Carburetor in Muncie and later worked at U.S. Steel Gary Works or Inland Steel East Chicago may have faced cumulative, career-long exposure at each stop.

Muncie Manufacturing produced precision-machined drivetrain and transmission components supplied directly to major American automakers, placing it among Indiana’s core Tier 1 and Tier 2 automotive suppliers from the 1930s through the 1980s.

Holley Carburetor is one of the most recognized names in American automotive history. Holley carburetors were standard equipment on muscle cars, commercial vehicles, and aircraft engines. Producing them at the tolerances automakers demanded meant running die casting machines, plating tanks, machining centers, and industrial boilers in high-temperature, high-volume production environments around the clock.

Both operations reportedly employed hundreds of Muncie-area residents at their peak. Both drew on the same pool of tradespeople — pipefitters, insulators, boilermakers, maintenance mechanics, and electricians — who cycled between the city’s major industrial employers throughout their careers.

The Period of Peak Asbestos Use: 1930s Through the Late 1970s

From roughly the 1930s through the late 1970s, asbestos-containing materials were the accepted industry standard for thermal insulation, fireproofing, and equipment protection in American heavy industry. Facilities like those operated by Holley Carburetor and Muncie Manufacturing reportedly used these materials for the same reasons every comparable Indiana plant did: they were inexpensive, effective at high temperatures, and actively marketed as safe by the manufacturers who produced them.

The science was clear inside these companies decades before any public warnings reached workers. Industry documents obtained through litigation establish that major asbestos manufacturers possessed internal research proving asbestos caused lung cancer and mesothelioma as early as the 1930s and 1940s. Despite that knowledge, these companies continued marketing asbestos-containing products to industrial facilities and suppressed hazard information from workers, employers, and regulators.

Suppliers of asbestos-containing materials to Midwestern industrial plants — including those in the Muncie area — may have included:

Johns-Manville Corporation — pipe insulation, block insulation, asbestos cement products
Owens-Illinois (Kaylo product line) — preformed pipe and block insulation
Armstrong World Industries — pipe insulation and thermal protection products
Combustion Engineering — boiler insulation and refractory materials
W.R. Grace & Co. — asbestos-containing sealants and insulation products
Garlock Sealing Technologies — gaskets and packing materials with asbestos content
John Crane Co. — mechanical seals and packing materials
General Electric — electrical equipment with asbestos-containing components
Westinghouse Electric — switchgear, arc chutes, and electrical insulation containing asbestos

Indiana industrial distributors and insulation contractors brought these products into Muncie-area plants during original construction and recurring maintenance shutdowns. Workers at these facilities may have been exposed to asbestos-containing materials supplied by these manufacturers throughout that period.

OSHA did not issue meaningful regulations limiting occupational asbestos exposure until the mid-1970s. Large-scale abatement programs did not begin until the 1980s. Workers who spent careers in these facilities before that period may have accumulated substantial cumulative exposures — with no protective equipment, no hazard disclosures, and no medical monitoring.

If you have been diagnosed with mesothelioma or asbestosis and worked at Holley Carburetor, Muncie Manufacturing, or any other Indiana industrial facility during this era, Indiana’s two-year filing deadline under Ind. Code § 34-20-3-1 applies from the date of your diagnosis. Contact an experienced Indiana asbestos attorney immediately.

Where Asbestos-Containing Materials Were Allegedly Present at Muncie Industrial Facilities

Where these materials were located matters enormously to your case. Workers who never directly handled asbestos-containing materials may still have been exposed to fibers released during nearby maintenance, repair, or removal activities — what occupational health researchers call “bystander exposure.” Courts and trust funds recognize bystander exposure as a legally compensable exposure pathway.

Pipe Insulation and Steam System Lagging

Industrial manufacturing facilities of this era required extensive steam distribution systems to power presses, maintain process temperatures, and heat buildings. Pipes carrying steam and hot water are reported to have been insulated with preformed pipe insulation sections manufactured by Johns-Manville, Owens-Illinois (Kaylo), and Armstrong World Industries — products that may have contained chrysotile and amosite asbestos at concentrations ranging from 15% to 85% by weight.

Cutting, fitting, or removing this insulation during maintenance may have released respirable asbestos fibers into surrounding work areas. Workers in adjacent areas — not only the insulators performing the work — may have inhaled those fibers. This bystander exposure pathway is well-documented in the occupational health literature and has been recognized in Indiana asbestos litigation as a significant source of compensable exposure.

The same pipe insulation products allegedly present at Holley Carburetor and Muncie Manufacturing were reportedly present throughout the Indiana steel corridor at U.S. Steel Gary Works and Inland Steel East Chicago, supplied through common Indiana industrial distributors serving the statewide manufacturing base.

Block and Blanket Insulation on Boilers and Furnaces

Industrial boilers and heat-treat furnaces used in casting operations are reported to have been insulated with rigid block insulation shaped to fit curved and flat surfaces. Products supplied by Johns-Manville and W.R. Grace may have been present on boilers, heat exchangers, and furnace walls throughout these facilities.

Routine boiler maintenance reportedly generated asbestos-containing dust during:

Descaling boiler tubes
Replacing refractory materials
Removing deteriorated insulation
Replacing boiler seals and gaskets
Inspecting internal surfaces during scheduled outages

Boilermakers Local 374, which represented workers at Indiana industrial facilities including plants in the Muncie area, reportedly had members who performed this work throughout their careers at multiple facilities across the state.

Gaskets, Packing, and Valve Components

Throughout precision manufacturing environments, gaskets and packing materials are reported to have sealed flanged pipe connections, pump housings, valve bodies, and equipment access panels. Products manufactured by Garlock Sealing Technologies and John Crane Co. may have contained compressed asbestos fiber ranging from 40% to 90% by weight.

Pipefitters and maintenance mechanics who routinely removed old gaskets — often scraping them from metal mating surfaces — may have faced repeated close-proximity exposure during this work. Multiplied over a career spanning decades, that daily removal and replacement activity represents a significant cumulative exposure source that initial exposure assessments frequently overlook. If this describes your work, tell your attorney — it matters.

Casting and Foundry Equipment Insulation

Die casting machines, furnaces, and ancillary equipment are reported to have been lined or insulated with refractory and insulating materials that may have contained asbestos-containing compounds. Workers maintaining this equipment — or working nearby during production — may have been exposed to fibers released during:

Normal production operation as equipment aged and deteriorated
Equipment repair and maintenance shutdowns
Furnace rebricking and refractory replacement
Mold changes and equipment servicing
Heat-treat cycle operations

Plating Tank Insulation and Electrical Equipment

The electroplating operations used in carburetor manufacturing — chrome plating, zinc plating, and related finishing processes — reportedly required temperature-controlled tank environments. Insulating materials used on plating tanks and associated piping may have contained asbestos-containing compounds.

Electrical equipment throughout these facilities is also reported to have contained asbestos-containing components, including:

Switchgear panels and electrical enclosures manufactured by General Electric and Westinghouse Electric
Arc chutes and thermal insulation within electrical panels
Wire and cable insulation in high-temperature service areas
Motor insulation on production equipment

Electricians performing maintenance on this equipment may have
