Who May Have Been Exposed at Southern Illinois University Carbondale Campus Illinois

Insulators (Asbestos Workers)

Insulators—members of Heat and Frost Insulators Local 1 (St. Louis, MO)—carried the highest disease risk of any occupational group at steam-system facilities. Their work required direct, sustained, hands-on contact with asbestos-containing materials.

Insulator exposures at SIUC allegedly included:

• Mixing asbestos-containing insulating cements by hand— Thermobestos and compounds—generating heavy airborne dust without respiratory protection
• Applying pre-formed pipe-covering sections ( calcium silicate pipe insulation, high-temperature pipe insulation, and Superex) to steam distribution piping
• Cutting pipe covering sections with hacksaws and utility knives—operations that released significant fiber concentrations into the breathing zone
• Applying finishing cements and canvas jacketing over installed insulation, disturbing settled fibers
• Removing deteriorated insulation during maintenance—the highest-exposure task; calcium silicate pipe insulation and Thermobestos products became brittle after decades of thermal cycling and shed fibers with every cut

Latency timeline: Mesothelioma typically manifests 20 to 50 years after first exposure. An insulator who worked at SIUC during the 1960s and 1970s expansion era is now squarely within that disease window. If you’re experiencing symptoms—chest pain, shortness of breath, unexplained pleural effusion—call a Illinois mesothelioma attorney before you do anything else.

Pipefitters and Steamfitters

Pipefitters and Steamfitters—members of Plumbers and Pipefitters UA Local 562 (St. Louis, MO)—worked alongside insulators throughout the SIUC steam system and may have been exposed to asbestos from multiple sources.

Bystander exposure: They worked in the same confined spaces—boiler rooms, mechanical rooms, steam tunnels—where Heat and Frost Insulators Local 1 members were actively applying or removing asbestos insulation. They breathed contaminated air throughout those operations, with no meaningful protection.

Gasket and packing work: Pipefitters installed and removed valve packing and flange gaskets directly. High-temperature steam valves used compressed asbestos fiber packing manufactured by gaskets and packing; high-temperature pipe insulation gaskets were standard throughout the system. Removing old gaskets required scraping, grinding, or wire-brushing—operations that directly released asbestos fibers into the air.

Pipe joint compounds: Threaded joints were sealed with asbestos-containing compounds. Removing corroded fittings coated with asbestos-contaminated thread sealant generated additional exposure on every job.

Boilermakers

Boilermakers who built, maintained, and repaired boilers at SIUC’s central heating plant faced particularly intense exposures from multiple product lines.

Asbestos-containing boiler components allegedly included:

• Exterior block insulation on boilers, fireboxes, and ductwork several inches thick— Superex and Cranite board were common specifications
• Rope and blanket gaskets on boiler doors, manholes, and inspection ports requiring regular replacement—gaskets and packing and supplied these components
• Refractory materials in fireboxes, often reinforced with asbestos fiber; refractory products carried substantial asbestos content
• Turbine and pump insulation on associated equipment— calcium silicate pipe insulation and products

Boiler repair required physically demolishing deteriorated and Cranite insulation, welding and cutting on boiler components immediately adjacent to asbestos materials, and reinstalling new insulation—all inside confined, poorly ventilated boiler rooms where fiber concentrations accumulated.

Boiler manufacturers common at SIUC-era university installations:

These boilers shipped with asbestos insulation applied at the factory. Field insulators from Heat and Frost Insulators Local 1 then added additional insulation and gasket materials from gaskets and packing and on-site.

Stationary Engineers and Operating Engineers

Stationary engineers—members of the International Union of Operating Engineers within SIUC Physical Plant—ran day-to-day operations of the central heating plant. Unlike insulators whose exposures were intense but episodic, stationary engineers absorbed daily cumulative doses over entire careers spent in boiler rooms and mechanical spaces where calcium silicate pipe insulation, Thermobestos, and Superex insulation continuously deteriorated around them.

Exposure sources for operating engineers included:

• Breathing air contaminated by deteriorating and insulation throughout boiler rooms and mechanical spaces, shift after shift, year after year
• Maintaining, adjusting, and repairing equipment wrapped in gaskets and packing and asbestos materials
• Sweeping and cleaning boiler rooms where calcium silicate pipe insulation, Thermobestos, and Superex debris had accumulated on every horizontal surface
• Opening insulated equipment for routine maintenance, disturbing settled fibers with every access panel removed

Electricians

Electricians installing electrical systems, lighting, and control systems in SIUC’s boiler plant and mechanical spaces may have been exposed throughout their work, even without handling asbestos-containing products directly.

Electrical work in asbestos environments:

• Running conduit and cable through boiler rooms, mechanical rooms, and steam tunnels where calcium silicate pipe insulation and Superex insulation lined every surface
• Installing electrical panels and controls in areas where Heat and Frost Insulators Local 1 members were actively applying or stripping insulation
• Maintaining electrical systems adjacent to deteriorating insulation—vibration from electrical equipment continuously dislodged fibers from surrounding asbestos materials into the air

Courts have repeatedly recognized that bystander exposure—breathing contaminated air without touching the product—is sufficient to establish causation in asbestos litigation. Electricians at facilities like SIUC have recovered substantial verdicts and settlements on exactly this theory.

Secondary Exposure: Family Members

Family members of trades workers—particularly spouses and children of Heat and Frost Insulators Local 1 and Plumbers and Pipefitters UA Local 562 members—received significant asbestos exposure through contaminated work clothing. These cases are well-established in the case law and have resulted in substantial recoveries.

• Workers who wore the same clothes across multiple workdays accumulated calcium silicate pipe insulation, Thermobestos, and gaskets and packing fibers in the fabric
• Asbestos fibers embedded in clothing, hair, and skin after direct contact with insulation and gasket materials throughout the workday
• Family members who laundered work clothes are alleged to have inhaled fibers released during washing and handling of contaminated garments
• Children who played near workers or handled their clothing absorbed fibers products

If your father or husband worked the SIUC physical plant and you have a mesothelioma diagnosis today, that is not a coincidence—and you have legal rights.
