Asbestos Exposure in Chicago’s Historic Firehouses: What Missouri Workers Need to Know

For more than a century, men and women who maintained and worked within Chicago Fire Department (CFD) firehouses may have been exposed to asbestos-containing materials in the buildings where they lived, trained, ate, and slept between calls. Firefighters faced obvious dangers in the field. Inside the firehouse, a separate threat may have been accumulating in the walls, ceilings, floors, and mechanical systems—often without warning, without protective equipment, and without any awareness of the risk.

If you worked at a Chicago Fire Department facility and have since been diagnosed with mesothelioma or another asbestos-related disease, a Missouri asbestos attorney can help you identify responsible manufacturers, navigate the Missouri mesothelioma settlement process, and meet your filing deadlines. This guide is written for:

Current and former CFD maintenance workers
Construction and renovation tradespeople who worked in CFD facilities
Firefighters who may have been exposed to disturbed building materials
Families facing a diagnosis of mesothelioma, asbestosis, lung cancer, or another asbestos-related disease
Missouri residents seeking an asbestos cancer lawyer in St. Louis or elsewhere in the state

Asbestos-Containing Materials in Chicago Fire Department Buildings

How Asbestos Entered Municipal Firehouses

Asbestos is a naturally occurring fibrous silicate mineral valued throughout the twentieth century for its heat resistance, tensile strength, chemical stability, and fire-retardant properties. From approximately 1900 through the late 1970s, manufacturers incorporated asbestos into hundreds of commercial building products across every construction category—insulation, fireproofing, roofing, flooring, acoustical treatments, and mechanical systems.

Public buildings like firehouses faced strict fire-resistance standards. Asbestos-containing materials were not merely common in these structures—architects, engineers, and city building departments specifically required or strongly preferred them. The buildings chosen to house fire protection equipment may have slowly poisoned the workers who built and maintained them.

Why Chicago Firehouses Accumulated Heavy ACM Use

Fire Resistance Requirements: Municipal building codes required fire-resistant construction in public safety facilities. Asbestos-containing fireproofing was the dominant solution for decades.

Steam Heat Systems: Chicago firehouses ran large boilers and extensive steam distribution systems. Boilers, pipes, valves, and fittings were routinely insulated with asbestos-containing materials.

Apparatus Bay Construction: Vehicle bays required durable, fire-resistant flooring and ceiling materials. Asbestos-containing floor tiles and acoustic ceiling materials were commonly installed.

Age of Building Stock: Many Chicago firehouses were constructed during peak asbestos use—1920 through 1980—and reportedly accumulated multiple generations of asbestos-containing materials through successive renovations.

Deferred Maintenance: Aging asbestos-containing materials were reportedly patched and repaired rather than properly abated, creating ongoing exposure risks for maintenance workers every time those materials were disturbed.

Construction Timeline: When Asbestos-Containing Materials Were Installed at Chicago Firehouses

The Growth of Chicago’s Firehouse Network

The Chicago Fire Department traces its formal origins to 1858. Following the Great Chicago Fire of October 1871, city leaders built a modern, professional fire department with permanent firehouse facilities. Between the 1870s and the mid-twentieth century, Chicago constructed dozens of firehouse buildings across its neighborhoods. At its peak, the CFD operated more than 100 firehouses, making it one of the largest municipal fire departments in the United States.

Many firehouses built between approximately 1880 and 1980 remain standing today. Numerous facilities were constructed or substantially renovated during the era when asbestos-containing materials were the industry standard for fire-resistant construction.

Key Construction Eras and ACM Installation

1880–1920: Early Firehouses

Heavy masonry construction. Pipe insulation, boiler insulation, and early fireproofing materials manufactured by Johns-Manville and Owens-Illinois may have contained asbestos at facilities built or renovated during this period.

1920–1945: Network Expansion

Widespread use of asbestos-containing pipe covering, boiler lagging, roofing felts, and floor tiles in public building construction. Products from Johns-Manville, Armstrong World Industries, and W.R. Grace were among those reportedly used in municipal facilities of this era.

1945–1980: Post-War Construction and Renovation

Heavy use of asbestos-containing spray-applied fireproofing—including Monokote products—along with acoustic ceiling tiles, floor tiles, joint compound, insulating cements, and gasket materials. Manufacturers supplying these product categories during this period included Owens Corning, Georgia-Pacific, Armstrong World Industries, and Celotex. Acoustic ceiling materials including Gold Bond and Sheetrock-brand products may have contained asbestos. Insulation products such as Kaylo and Thermobestos pipe insulation were widely installed during post-war construction and renovation projects.

1980–Present: Regulated Era

Federal asbestos regulations drove new construction away from asbestos-containing materials. Abatement projects and disturbance of legacy materials during renovation and repair work reportedly continued to present asbestos exposure risks for maintenance workers well into the 1990s and beyond.

Occupational Groups Most at Risk for Asbestos Exposure at CFD Facilities

Insulators and Insulation Workers

Insulators rank among the occupational groups with the highest rates of asbestos-related disease in the United States. Workers employed by insulation contractors or the City of Chicago’s facility maintenance departments who performed insulation work on boilers, pipes, tanks, and mechanical equipment in CFD firehouses may have been exposed to:

Asbestos-containing pipe covering and Kaylo blanket insulation
Block insulation and Thermobestos products
Aircell and other proprietary insulation materials
Asbestos-containing insulating cements

Members of Heat and Frost Insulators Local 1 and other regional insulation trade unions, as well as direct City of Chicago maintenance personnel, may have performed such work. Cutting, sawing, fitting, and applying pipe insulation that contained asbestos generates respirable fibers. Workers employed by City of Chicago public works departments or private insulation contractors engaged for renovation and capital improvement projects may have performed this work in CFD facilities. If you are a union insulators member or maintenance worker who has been diagnosed with mesothelioma, a Missouri asbestos attorney can evaluate your potential claims today.

Pipefitters and Steamfitters

Pipefitters and steamfitters who installed, maintained, and repaired steam heating systems in Chicago firehouses—whether employed by the City of Chicago or working under union agreements—may have been exposed to asbestos-containing materials through several pathways:

Pipe covering and lagging: Asbestos-containing insulation on steam and hot water pipes—including products from Johns-Manville and Owens-Illinois—was routinely disturbed during fitting and valve work.

Gaskets and packing: Pipe joints, valve stems, and pump seals in high-temperature systems were routinely packed and gasketed with asbestos-containing materials reportedly manufactured by Garlock Sealing Technologies and Armstrong World Industries.

Insulating cement: Pipefitters frequently applied or disturbed asbestos-containing insulating cements used to finish pipe covering and repair insulation systems.

Boilermakers

Boilermakers who constructed, repaired, and maintained large steam boilers in older Chicago firehouses may have faced some of the most intensive asbestos exposures in the building trades. Boiler work typically involved:

Removing and replacing asbestos-containing boiler lagging and block insulation reportedly manufactured by Johns-Manville and Crane Co.
Working with asbestos-containing refractory cements and castable refractories used to line fireboxes and combustion chambers
Applying and disturbing rope and sheet gaskets reportedly manufactured by Garlock Sealing Technologies and other suppliers, used to seal boiler doors, manholes, and inspection ports
Working in confined spaces where asbestos fiber concentrations could reach dangerous levels

Electricians

Electricians performing installation, maintenance, and upgrade work in Chicago firehouses may have been exposed to asbestos-containing materials through:

Drilling and cutting through walls and ceilings: Electrical work routinely required penetrating walls, ceilings, and floors that may have contained asbestos-containing materials—including Gold Bond and Sheetrock joint compounds, insulating cements, and fireproofing products such as Monokote.

Electrical insulation: Certain older electrical wiring, panel components, and arc-chute materials in switchgear reportedly contained asbestos-containing materials manufactured by Eagle-Picher and Combustion Engineering.

Bystander exposure: Electricians working in the same areas as insulators, pipefitters, and boilermakers may have been exposed to asbestos fibers released by those workers’ activities.

Carpenters and Drywall Workers

Carpenters, drywall installers, and finishers who performed renovation work in Chicago firehouses may have been exposed to:

Asbestos-containing joint compounds and spackling materials reportedly manufactured by Georgia-Pacific, USG (United States Gypsum), and Armstrong World Industries—products widely sold through the mid-1970s—used to tape, bed, and finish drywall
Asbestos-containing acoustic ceiling tiles including Gold Bond and similar institutional products, routinely cut and fitted during renovation work
Asbestos-containing floor tiles and Pabco brand resilient flooring cut, sanded, or broken during removal or new installation

Plumbers

Plumbers working in CFD facilities may have encountered asbestos-containing materials in:

Pipe insulation systems, including Kaylo products
Gaskets and plumbers’ putty reportedly manufactured by Garlock Sealing Technologies and Armstrong World Industries
Insulated pipe runs disturbed during drain, waste, and vent work
Valve and fitting insulation systems

HVAC Mechanics and Sheet Metal Workers

HVAC mechanics and sheet metal workers who installed, maintained, or modified heating, ventilation, and air conditioning systems in Chicago firehouses may have been exposed to:

Asbestos-containing duct insulation including products reportedly from Johns-Manville and Owens Corning
Asbestos-containing mastic adhesives used to seal ductwork joints
Asbestos-containing gaskets in air handling equipment reportedly manufactured by Crane Co. and other suppliers

Custodians and Maintenance Workers

General maintenance workers and custodians employed at CFD firehouses may have been exposed to asbestos-containing materials through routine cleaning and maintenance activities:

Sweeping, mopping, and buffing damaged or deteriorating asbestos-containing floor tiles—including vinyl asbestos tiles and Pabco brand materials—can release respirable asbestos fibers
Patching or repairing deteriorating insulation without proper respiratory protection
Removing damaged ceiling tiles that may have contained asbestos-containing materials
Applying joint compound reportedly manufactured by Georgia-Pacific and Armstrong World Industries

Firefighters and Station Personnel

Firefighters and other station personnel who spent significant portions of their careers in older Chicago firehouses may also have been exposed to disturbed or deteriorating asbestos-containing materials within those facilities. Exposure risk was reportedly highest during renovation projects undertaken while the firehouse remained in operation and during periods of deferred building maintenance when damaged materials went unaddressed.

Specific Asbestos-Containing Products: What May Have Been Present at CFD Facilities

Based on the types of construction, renovation, and mechanical systems typically found in large municipal public safety facilities of the relevant era, the following categories of asbestos-containing products are among those that may have been present in Chicago Fire Department facilities.

Pipe Insulation and Thermal Systems

Asbestos-containing pipe insulation was the industry standard for steam pipes, hot water pipes, and high-temperature process piping from approximately 1900 through the late 1970s. Products that may have been present in CFD facilities include:

Kaylo (Owens-Illinois, later Owens Corning) — asbestos-containing calcium silicate pipe insulation widely distributed to industrial and municipal customers through the 1970s
Thermobestos (Carey-Canada / Philip Carey) — asbestos-containing pipe covering used extensively in commercial and institutional steam systems
