This article is for informational purposes only and does not constitute legal advice. If you or a family member has been diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, consult a qualified asbestos litigation attorney.
Urgent Filing Deadline Warning
If you or a loved one has been diagnosed with an asbestos-related disease, time is critical. Missouri’s statute of limitations for asbestos-related personal injury claims is five years from the date of diagnosis. Miss that deadline, and your right to compensation is gone — permanently. HB1649 proposes strict trust disclosure requirements for cases filed after August 28, 2026, which could further complicate your claim. Call a Missouri asbestos attorney today. Not next month. Today.
Your Health May Be Connected to Your Work at Midway Airport
If you spent your career maintaining, repairing, or building Chicago Midway International Airport — or if a family member did — you may be facing a health crisis tied directly to that work. The same infrastructure that made Midway one of the world’s busiest airports was reportedly built and maintained with asbestos-containing materials that are now causing mesothelioma, asbestosis, and lung cancer in workers who were never warned about the danger.
A Missouri mesothelioma lawyer can help you understand your legal options. This article explains what allegedly happened at Midway, which workers may have been affected, and what remedies are available through asbestos lawsuits, settlements, and asbestos trust fund claims in Missouri.

Facility History: Why Midway Airport Appears in Asbestos Litigation
Construction During the Asbestos Era
Chicago Midway International Airport opened in 1926 as Chicago Municipal Airport, serving as the nation’s primary commercial aviation hub. Major expansion ran through the 1930s, 1940s, and 1950s — the same decades when asbestos-containing materials dominated commercial construction across the United States, including the Missouri-Illinois industrial corridor along the Mississippi River.
Key dates:
- 1926: Airport opens; initial terminal, hangar, and support facility construction begins
- 1940s–1950s: Wartime and post-war expansion coincides with peak asbestos manufacturing and use by companies including Johns-Manville, Owens-Illinois, and Celotex
- 1947: Renamed Chicago Midway Airport following the Battle of Midway
- 1950s: Reaches peak status as the world’s busiest airport; extensive terminal, concourse, and mechanical system expansion allegedly drives intensive asbestos-containing material installation by manufacturers including Armstrong World Industries, Georgia-Pacific, and W.R. Grace
- 1963: O’Hare International Airport opens; Midway’s passenger traffic declines, but maintenance and renovation work intensifies
- 1981: Near-closure and subsequent revival trigger additional renovation and demolition activity
- 2001: $743 million terminal renovation completed, requiring asbestos surveys and abatement under federal NESHAP regulations
Why the Construction Timeline Matters
Federal asbestos regulation essentially did not exist until:
- OSHA established workplace asbestos standards in 1972, with enforcement beginning mid-decade
- EPA issued initial asbestos manufacturing regulations in the late 1970s
- NESHAP regulations for asbestos abatement were finalized in the 1990s
Before those dates, asbestos-containing materials were:
- Considered a fire-resistant, heat-insulating, durable, and inexpensive building standard
- Specified on virtually all commercial construction projects by manufacturers including Johns-Manville, Owens-Illinois, Eagle-Picher, and Garlock Sealing Technologies
- Installed by workers who received no warnings, no protective equipment, and no health information
- Applied in dozens of product forms across every part of the facility
Thousands of construction, trades, and maintenance workers labored at Midway during this unregulated period. Many now carry diagnoses of mesothelioma, asbestosis, and other asbestos-related diseases. A skilled Missouri asbestos attorney can help determine whether your exposure history qualifies for compensation.
Workers affiliated with Heat and Frost Insulators Local 1 and Plumbers and Pipefitters UA Local 562, among other unions active in the Chicago area, may have been among those affected.
Asbestos-Containing Materials at Midway: What Was Used and When
Why Airports Used Asbestos-Containing Materials
Airport construction specified asbestos-containing materials for three primary reasons:
Fire resistance
- Fuel storage, aircraft operations, and public safety codes demanded extensive fireproofing throughout the facility
- Spray-applied asbestos fireproofing products such as Monokote, manufactured by W.R. Grace, were the industry standard method for protecting structural steel
- Asbestos-containing floor finishes and coatings added a secondary fire-resistance layer in high-risk areas
Thermal insulation
- Steam distribution systems, boiler rooms, and mechanical plant rooms required robust insulation
- Asbestos-containing pipe insulation products — including Kaylo and Thermobestos — along with block insulation and blanket insulation from Johns-Manville, Owens-Illinois, and Celotex were industry standards
- High-temperature applications including boilers, turbines, and heat exchangers relied on asbestos-containing materials from Combustion Engineering and similar manufacturers
Acoustic control and durability
- Terminal buildings required noise reduction from jet aircraft; asbestos-containing acoustic tiles and spray-applied materials were the standard solution
- Vinyl asbestos floor tiles in 9"×9" and 12"×12" formats from Armstrong World Industries and Celotex were standard in high-traffic terminal and concourse areas
- Asbestos-containing roofing and exterior materials offered weather and wear resistance across the facility
Reported Asbestos-Containing Material Sources by Construction Period
1930s–1940s: Early Construction
Early terminal and hangar construction allegedly incorporated asbestos-containing materials from manufacturers including:
- Johns-Manville asbestos-containing pipe insulation on steam and hot water systems
- Owens-Illinois boiler insulation in mechanical plant rooms
- Roofing materials reportedly containing asbestos from Georgia-Pacific and Celotex
- W.R. Grace asbestos-containing fireproofing compounds on structural elements
1940s–1950s: Wartime and Post-War Expansion
This intensive construction period allegedly included:
- Asbestos-containing thermal insulation on boiler systems and steam distribution networks from Johns-Manville and Owens-Illinois
- Spray-applied Monokote fireproofing on structural steel throughout the facility
- Kaylo and Thermobestos asbestos-containing pipe insulation in HVAC systems, chilled water lines, and fuel distribution systems
- Asbestos-containing gaskets and packing materials from Garlock Sealing Technologies in valve assemblies and pump systems
- Asbestos-containing roofing materials including Pabco products on terminal and support structures
1950s–1960s: Terminal Expansion
Midway’s peak expansion reportedly involved:
- Vinyl asbestos floor tiles from Armstrong World Industries and Gold Bond throughout terminal areas and concourses
- Asbestos-containing ceiling tiles and acoustic materials from Celotex and Johns-Manville
- Additional asbestos-containing pipe and thermal insulation from Owens-Illinois and Eagle-Picher as mechanical systems expanded
- Asbestos-containing gaskets, packing, and sealants from Garlock Sealing Technologies across the facility
- Asbestos-containing roofing materials from Celotex and Pabco on expanded terminal structures
1960s–1980s: Maintenance, Repair, and Renovation
As Midway shifted from primary to secondary airport status, maintenance and renovation work became constant:
- Boilermakers, pipefitters, and maintenance technicians may have regularly disturbed previously installed asbestos-containing materials from Johns-Manville, Owens-Illinois, and other manufacturers
- Renovation activities allegedly exposed workers to legacy asbestos-containing materials installed decades earlier
- No asbestos abatement or worker protection protocols existed through much of this period
1980s–2000s: Documented Abatement
The 2001 terminal renovation marked the first period at Midway where federal asbestos regulations governed major renovation work:
- Federal NESHAP regulations required asbestos surveys before demolition, potentially documenting the presence of Monokote, Kaylo, vinyl asbestos floor tiles, and other asbestos-containing materials (documented in NESHAP abatement records)
- Abatement records from this period may identify asbestos-containing materials from manufacturers including Johns-Manville, Owens-Illinois, Celotex, Armstrong World Industries, and Crane Co.
- Renovation work through this period may have continued exposing workers to legacy materials
High-Risk Trades and Occupations at Midway Airport
Large commercial airports draw on virtually every construction and maintenance trade. Workers in the following occupations may have faced the highest documented exposure risk based on the nature of their work and their proximity to asbestos-containing materials.
Insulators (Heat and Frost Insulators / Asbestos Workers)
Insulators may have faced the most direct and intensive contact with asbestos-containing materials at Midway.
This trade — historically called “asbestos workers” — installed, maintained, and removed thermal insulation on pipes, boilers, tanks, and mechanical equipment throughout the facility. Members of Heat and Frost Insulators Local 1 may have worked on expansion and maintenance projects at Midway.
Exposure-generating tasks at Midway may have reportedly included:
- Installing asbestos-containing pipe covering — including Kaylo and Thermobestos products — on steam and hot water distribution systems
- Applying asbestos-containing block insulation to boiler systems and heat exchangers in mechanical rooms
- Applying asbestos-containing cement and finishing compounds to pipe fittings, valves, and irregular surfaces from Johns-Manville and Owens-Illinois
- Mixing asbestos-containing insulating cements by hand, generating extremely high airborne fiber concentrations
- Cutting and fitting asbestos-containing insulation sections, releasing significant fiber loads into the breathing zone
- Secondary exposure from the simultaneous work of nearby pipefitters, boilermakers, and other trades
Pipefitters and Plumbers
Pipefitters and plumbers may have encountered asbestos-containing materials through multiple exposure pathways. Members of Plumbers and Pipefitters UA Local 562 and affiliated locals may have worked on Midway projects.
Pipe insulation disturbance
- Removing or disturbing asbestos-containing pipe insulation — including Kaylo and Thermobestos products — to access valves, flanges, and pipe sections for repair
- Routine maintenance and repair of pipes with legacy asbestos-containing insulation from Johns-Manville, Owens-Illinois, and Eagle-Picher
Gaskets and packing materials
- Cutting, fitting, and removing asbestos-containing gaskets from Garlock Sealing Technologies at pipe joints and flanges
