Asbestos Exposure at Township High School District 214 (Arlington Heights, IL): What Workers and Families Need to Know

Urgent Filing Deadline Warning

If you or a family member has been diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer after working at a school building in Missouri or Illinois, act now. Missouri law gives you five years from the date of diagnosis to file a civil claim under Mo. Rev. Stat. § 516.120. The deadline runs from diagnosis — not from the last day you worked around asbestos.

Pending legislation matters here. HB1649 would impose strict trust disclosure requirements on cases filed after August 28, 2026. If you are approaching that date, the procedural landscape changes. Call today to speak with an experienced asbestos attorney and protect what you have earned.

If You Worked at District 214 and Were Just Diagnosed

A diagnosis of mesothelioma, asbestosis, or asbestos-related lung cancer means the clock is already running. If you worked as a boilermaker, pipefitter, insulator, HVAC mechanic, electrician, millwright, or maintenance tradesman at any District 214 facility in Arlington Heights, Illinois, your legal rights may be substantial.

Missouri’s five-year statute of limitations under Mo. Rev. Stat. § 516.120 runs from the date of diagnosis — not from the last day of exposure. That distinction matters enormously to workers receiving diagnoses today for jobs they held in the 1970s, 1980s, or 1990s.

Veterans may pursue VA disability compensation simultaneously with a civil asbestos lawsuit. Both tracks run independently, and pursuing one does not foreclose the other. Waiting costs you evidence, witnesses, and documented exposure history that becomes harder to reconstruct with every passing month.

About District 214 and Its Facilities

The District and Its Campuses

Township High School District 214 serves the northwest Chicago suburbs of Arlington Heights, Buffalo Grove, Mount Prospect, Prospect Heights, Rolling Meadows, and Wheeling. The district operates multiple high school campuses, including:

  • Buffalo Grove High School
  • John Hersey High School
  • Prospect High School
  • Rolling Meadows High School
  • Wheeling High School
  • Forest View High School

When Asbestos Was Specified in These Buildings

These campuses were built primarily during the postwar construction boom of the 1950s and 1960s, with additions and expansions continuing into the early 1980s. Asbestos-containing materials in buildings of this era were not incidental — architects and engineers specified them deliberately as the industry standard.

From roughly 1945 through 1978, asbestos-containing materials (ACM) were the standard specification for:

  • Thermal insulation on steam and hot-water piping
  • Boiler insulation block
  • Pipe covering
  • Floor tile and adhesive
  • Ceiling tile
  • Spray-applied fireproofing on structural steel
  • Duct insulation and flexible connectors

Workers who built these schools, and the tradesmen who maintained and renovated them across the following four decades, were reportedly exposed to asbestos fibers as a foreseeable and routine consequence of their work.

Who Was Exposed and How

Boilermakers

Boilermakers servicing and overhauling the large steam boilers that heated District 214 facilities reportedly disturbed asbestos block insulation and boiler rope gaskets during every maintenance cycle. Annual shutdowns and emergency repairs required direct physical contact with deteriorating, friable insulation. Crane Co. Cranite brand gaskets and valve packing and Combustion Engineering boiler components were standard in institutional systems of this construction era. These disturbance events may have released elevated fiber concentrations into confined mechanical room spaces with limited ventilation.

Pipefitters and Steamfitters

Pipefitters and steamfitters working on steam and hot-water distribution systems at District 214 facilities allegedly encountered deteriorating Johns-Manville Kaylo and Owens-Illinois pipe covering throughout mechanical rooms and ceiling plenums. Cutting, removing, and replacing pipe sections disturbed aged ACM at every repair. Combustion Engineering valve and fitting insulations were also common in systems of this construction period and are alleged to have been disturbed during routine replacement work.

Insulators

Insulators who applied or removed Johns-Manville Thermobestos pipe covering, Pittsburgh Corning Unibestos block insulation, and asbestos-containing duct wrap handled raw asbestos-containing products daily. Industrial hygiene literature documents insulators as experiencing peak fiber exposures among all building trades. Members of Heat and Frost Insulators Local 1 (St. Louis) and Heat and Frost Insulators Local 27 (Kansas City) who performed work at District 214 facilities may face elevated disease risk based on occupational cohort studies.

HVAC Mechanics

HVAC mechanics removing and replacing Owens Corning Aircell air handling unit insulation, asbestos-containing flexible duct connectors, and internal duct lining materials were reportedly exposed during routine service work. Seasonal maintenance involving Thermobestos or similar products often required entry into confined spaces where insulation deterioration was advanced and disturbance unavoidable.

Electricians and Millwrights

Electricians and millwrights drilling through W.R. Grace Monokote fireproofed decking, cutting through insulated pipe chases containing Kaylo or Unibestos, or pulling wire through Celotex asbestos-lined conduit systems may have disturbed ACM without recognizing it. These trades were not trained in asbestos identification and worked in areas where ACM carried no visible labeling.

In-House Maintenance and Plant Operations Staff

District custodial and plant operations staff who patched floors over asbestos-containing adhesive, replaced Celotex or Armstrong ceiling tiles, or worked around deteriorating Johns-Manville pipe insulation on a daily basis were allegedly subjected to chronic low-level exposure that medical literature associates with disease development. These workers typically accumulated the longest tenure at these facilities — and the highest cumulative exposure.

Family Members — Secondary Exposure

Family members of these tradesmen face documented risk from secondary asbestos exposure. Fibers carried home on work clothing, in hair, and on skin can contaminate household environments. Secondary exposure has reportedly caused mesothelioma in spouses and children who never set foot on a job site. If a family member developed mesothelioma or asbestosis after a tradesman worked at District 214 facilities, that secondary exposure history should be documented as part of any legal claim.

Asbestos Materials Reportedly Found at District 214 Facilities

District 214’s older buildings were constructed during the peak years of asbestos specification in institutional construction. The following ACM categories were commonly documented at facilities of this construction era and are among the materials at issue in asbestos injury litigation involving comparable school districts.

Pipe Covering and Block Insulation

Johns-Manville Kaylo and Thermobestos were widely specified for steam and hot-water pipe systems. Owens-Illinois and Owens Corning thermal insulation products and W.R. Grace pipe covering were also common in institutional construction of this era. When cut, abraded, or allowed to age into a friable state, these materials are alleged to have released elevated fiber concentrations during maintenance and renovation work.

Floor Tile and Adhesive

Armstrong World Industries floor tile and associated mastic adhesives containing asbestos were standard in school corridors, gymnasiums, and classrooms of this era. Celotex and Georgia-Pacific also manufactured asbestos-containing floor products. Sanding, scraping, or removing these tiles without proper containment may release chrysotile and amosite fibers.

Spray Fireproofing

W.R. Grace Monokote spray-applied fireproofing was commonly used on structural steel in buildings of this construction period. This material is notably friable and is documented in industrial hygiene literature as a high-fiber-release source during renovation and demolition. Eagle-Picher also manufactured spray-applied fireproofing products installed in institutional buildings of this era.

Ceiling Tile

Celotex, Armstrong, and Georgia-Pacific produced asbestos-containing acoustic ceiling tile widely installed in schools through the mid-1970s. Disturbance during maintenance access or renovation reportedly releases fibers. Electricians and maintenance staff who pulled cable or replaced filters through ceiling plenums may have disturbed this material without recognizing it as ACM.

Wallboard and Joint Compound

National Gypsum Gold Bond asbestos-containing joint compound and drywall products were used throughout this construction era. Celotex and other manufacturers also supplied asbestos-containing joint compounds that may have been sanded or disturbed during renovation and repair work.

Pipe Insulation Block

Pittsburgh Corning Unibestos pipe insulation block was commonly documented in institutional mechanical systems of this period. Johns-Manville and Owens-Illinois also manufactured rigid pipe insulation block. These materials are alleged to have been routinely disturbed by boilermakers and maintenance workers during seasonal outages and emergency repairs.

Gaskets and Packing Materials

Crane Co. Cranite brand gaskets and valve packing were standard in steam systems. Combustion Engineering supplied asbestos-containing gaskets and valve components to institutional boiler systems of this era. Garlock Sealing Technologies manufactured asbestos-containing gasket materials widely used in flanged connections throughout steam and hot-water distribution systems. Boilermakers, pipefitters, and maintenance workers reportedly disturbed these materials at every scheduled outage and emergency repair.

Duct Insulation and Flexible Connectors

Johns-Manville, Owens-Illinois, and Owens Corning supplied asbestos-containing duct insulation. W.R. Grace also manufactured duct insulation products used in institutional construction. Flexible duct connectors, ductwork wrap, and internal duct lining containing asbestos were common in air handling systems and are alleged to have been disturbed during HVAC maintenance and replacement work.

When Exposure Was Heaviest

Original Construction (1950s–1970s)

The tradesmen who built these schools — insulators, pipefitters, and boilermakers affiliated with UA Local 562 (St. Louis) and similar locals — worked with raw asbestos-containing products before any meaningful regulatory controls were in place. Fiber concentrations during installation of Kaylo, Thermobestos, Monokote spray fireproofing, and Armstrong floor tile were reportedly among the highest documented in occupational studies of this period. These installation exposures represent the earliest documented source of occupational risk for workers who remained in the trades for subsequent decades.

Maintenance Outages and Boiler Work (Ongoing Through the 1980s)

Annual boiler shutdowns required workers to remove and replace deteriorating insulation and gasket materials, including those manufactured by Combustion Engineering and Crane Co. Each outage allegedly released fibers into confined mechanical room spaces with limited ventilation. Members of Plumbers and Pipefitters UA Local 562 (St. Louis) and Plumbers and Pipefitters UA Local 268 (Kansas City) performing scheduled maintenance at District 214 facilities may face documented chronic exposure histories tied to these recurring events throughout their full tenures.

Renovation Periods (Peak Fiber Release)

Renovation work — drop ceiling removal, boiler replacement, pipe system upgrades, and fireproofing abatement — generated the highest documented fiber concentrations in school environments. Workers who performed renovation work at District 214 facilities before regulatory abatement requirements were in place were reportedly exposed to fiber levels that dwarf routine maintenance exposures. These events are the most legally significant for purposes of product identification and exposure documentation.

Workers diagnosed with mesothelioma, asbestosis, or asbestos-related lung cancer following occupational exposure at District 214 facilities may be eligible to pursue claims through several legal channels simultaneously.

Civil Litigation

Product liability claims against the manufacturers of asbestos-containing materials — including Johns-Manville, Crane Co., Combustion Engineering, W.R. Grace, Armstrong World Industries, Pittsburgh Corning, and Owens-Illinois — remain viable in Missouri civil courts. St. Louis City Circuit Court has historically been a favorable venue for asbestos product liability cases. Madison County, Illinois and St. Clair County, Illinois are additional venues with established asbestos litigation dockets where Missouri plaintiffs have successfully pursued claims.
