What Is Rush Presbyterian St. Luke’s Medical Center and Why Does It Matter for Asbestos Exposure?

A Hospital Built During Peak Asbestos Use

Rush Presbyterian St. Luke’s Medical Center — today known as Rush University Medical Center — is one of Chicago’s largest hospital complexes, located on the Near West Side in the city’s Medical District. The campus employed thousands of workers across multiple trades over more than a century of construction, expansion, and renovation.

The medical center was built and significantly expanded during the decades when asbestos use in American institutional construction was at its height:

Original hospital buildings (early 1900s–1930s)
Major expansion during the 1950s–1970s — the highest-risk period for asbestos-containing material use
Continuous renovation and modernization through the 1990s and 2000s

This timeline placed workers directly in contact with asbestos-containing materials (ACMs) that were standard building products throughout that era.

The History of Rush Presbyterian St. Luke’s: When ACM Use Was Highest

How Two Historic Chicago Hospitals Merged

Rush Medical College was founded in 1837, one of the first medical schools west of the Allegheny Mountains. Presbyterian Hospital (established 1883) and St. Luke’s Hospital (roots dating to the 1860s) both served Chicago’s growing population. These institutions merged across the twentieth century to form the unified Rush Presbyterian St. Luke’s Medical Center at its current West Side campus.

Construction in the 1950s–1970s Brought ACMs Into the Facility

The hospital underwent its most dramatic physical expansion precisely when asbestos-containing material use in commercial and institutional construction peaked. That era reportedly included:

Patient tower additions with sprayed fireproofing systems applied to structural steel
Boiler rooms and central steam plant facilities insulated with asbestos-containing pipe covering and block insulation
HVAC, mechanical, and plumbing systems throughout the complex fitted with asbestos-containing thermal protection products
Ancillary buildings, research facilities, and outpatient centers incorporating asbestos-containing drywall, ceiling tiles, and roofing materials
Renovation of earlier twentieth-century structures involving previously installed ACMs

Workers installing these systems may have been exposed to significant quantities of airborne asbestos fibers. Architects, engineers, and hospital administrators specified these materials as industry-standard products — while manufacturers allegedly knew the health consequences and said nothing.

Renovation Work Continued ACM Disturbance Risk Through the 2000s

Even after new construction with ACMs was phased out, workers performing renovation, repair, and maintenance on systems installed in prior decades continued to encounter previously installed asbestos-containing materials. The hospital’s ongoing modernization — including construction of the Pavilion building in the 1990s and 2000s — involved renovation and demolition that allegedly disturbed ACMs already in place.

Why Asbestos-Containing Materials Were Everywhere in Hospital Construction

Fire Resistance Drove Institutional ACM Use

Hospitals are densely occupied buildings where fire codes are strict. Asbestos was widely regarded as ideal for fireproofing because of its heat resistance and durability. Building codes, fire safety standards, and insurance requirements drove asbestos-containing fireproofing products into the institutional construction industry. Sprayed asbestos fireproofing — manufactured by Johns-Manville, W.R. Grace & Co., and Combustion Engineering — was routinely applied to structural steel beams, columns, and decking in large buildings constructed between 1940 and 1973.

Hospital Mechanical Systems Required Extensive ACM Insulation

Hospitals consume enormous quantities of steam and hot water for sterilization, heating, laundry, and clinical operations. The pipes, boilers, turbines, and mechanical equipment delivering that energy were routinely insulated with asbestos-containing products from manufacturers including:

Johns-Manville (pipe covering and block insulation)
Owens-Illinois (insulation products)
Eagle-Picher (thermal insulation)
Garlock Sealing Technologies (gaskets and packing)
Crane Co. (valve insulation and components)
Armstrong World Industries (mechanical system components)

These products were considered the most cost-effective insulating materials available during the mid-twentieth century. Workers installing or disturbing them may have been exposed to asbestos fibers at concentrations far exceeding what we now know to be safe.

ACMs Were Built Into Every Layer of the Building

Asbestos-containing products were reportedly incorporated throughout hospital construction at every level:

Floor tiles and adhesives (Georgia-Pacific, Celotex, Armstrong World Industries)
Ceiling tiles and spray-applied acoustic coatings (Armstrong World Industries, Celotex)
Drywall joint compound (Gold Bond and Sheetrock products from United States Gypsum Company)
Wallboard and plaster products (various manufacturers)
Roofing materials (Pabco and various regional suppliers)
Gaskets and packing materials (Garlock Sealing Technologies, Crane Co.)
Valve packing and rope (Garlock Sealing Technologies)
Flange insulation and wrapping (Johns-Manville, Owens-Illinois)

The Industry Allegedly Knew the Risks — Workers Did Not

Occupational health risks of asbestos were known to industry insiders for decades before workers received any warning. Internal documents produced in asbestos litigation have shown that manufacturers allegedly suppressed and withheld that information from workers and the public.

The regulatory timeline tells part of the story:

OSHA was not created until 1970
Meaningful asbestos exposure limits were not established until the mid-1970s
Workers at Rush Presbyterian St. Luke’s during the 1950s, 1960s, and early 1970s operated without enforceable exposure limits, respiratory protection requirements, or hazard warnings of any kind

That is not an accident. That is why asbestos litigation exists.

Specific Asbestos-Containing Products Allegedly Present at Rush Presbyterian St. Luke’s

Based on documented construction practices at large institutional facilities in Chicago and the established timeline of ACM use in the United States, the following products were reportedly present at this facility.

Pipe Insulation and Covering Systems

Asbestos-containing products used to insulate steam pipes, hot water pipes, and chilled water pipes throughout the mechanical systems reportedly included:

Pre-formed pipe covering with asbestos fibers in the base material, manufactured by Johns-Manville, Owens-Illinois, and Eagle-Picher

Calcium silicate products used for high-temperature applications
Thermobestos and other proprietary asbestos insulation products
Asbestos rope and cord used as sealing material on pipe joints, manufactured by Garlock Sealing Technologies

Fireproofing and Structural Protection

Sprayed asbestos fireproofing reportedly applied to structural steel, columns, and decking included products from:

Johns-Manville
W.R. Grace & Co. (spray-applied fireproofing products)
Combustion Engineering (proprietary fireproofing systems)
Regional applicators and subcontractors working on Chicago institutional projects during the 1950s–1970s

Boiler Room and Steam Plant Materials

Asbestos-containing refractory materials for boiler lining
Asbestos-containing insulating brick from Johns-Manville and others
Block insulation on boiler exteriors
Pipe insulation throughout the steam distribution system
Asbestos rope gaskets at boiler access points and connections, manufactured by Garlock Sealing Technologies and Crane Co.
Asbestos-containing cement used for boiler sealing and patching

Building Components and Interior Materials

ACMs were allegedly incorporated into general building construction throughout the campus, including:

Floor tiles — 9×9" and 12×12" asbestos-containing vinyl composition tile from Georgia-Pacific and Celotex
Mastics and adhesives used to install floor tiles
Ceiling tiles and spray-applied acoustic coatings from Armstrong World Industries and Celotex
Drywall joint compound containing asbestos fibers in Gold Bond and Sheetrock brand products from United States Gypsum Company
Wallboard and plaster products with asbestos content
Roofing materials including Pabco-brand products

Mechanical Equipment Components

Gaskets, packing materials, and components in mechanical equipment reportedly contained asbestos, including:

Valve packing and rope from Garlock Sealing Technologies and Crane Co.
Flange gaskets with asbestos content
Heat-resistant electrical insulation containing asbestos fibers
Asbestos-containing caulk and sealants used in mechanical assemblies
Pump packing boxes fitted with asbestos rope
Turbine insulation in steam-driven equipment

Who Was Most at Risk? Trades and Occupations with Highest Asbestos Exposure

Workers across many trades may have been exposed to asbestos-containing materials at Rush Presbyterian St. Luke’s Medical Center. The following occupational categories faced the highest documented exposure risk based on the work they performed and the ACMs they allegedly encountered.

Insulators (Heat and Frost Insulators) — Highest Risk

Insulators rank among the most heavily exposed workers in all construction trades. Members of the International Association of Heat and Frost Insulators and Allied Workers (HFIAW) — including Chicago-area locals and those from Missouri such as Heat and Frost Insulators Local 1 — may have been directly responsible for:

Installing asbestos-containing pipe covering on steam pipes, boilers, and chillers
Removing and replacing asbestos-containing block insulation during renovation projects
Wrapping and sealing asbestos-containing insulation on mechanical equipment
Performing insulation work that allegedly generated high concentrations of airborne asbestos fibers during the 1950s–1970s construction and modernization campaigns

Insulators who handled friable asbestos-containing materials without respiratory protection during this period face some of the highest rates of mesothelioma and asbestosis of any occupational group in the country.

Pipefitters and Steamfitters

Pipefitters and steamfitters working in the hospital’s central plant and throughout its mechanical systems may have been exposed to asbestos-containing materials through:

Cutting, threading, and joining pipes covered with asbestos-containing insulation
Removing pipe covering to access joints and valves for repair
Working alongside insulators who were simultaneously generating asbestos fiber clouds
Replacing asbestos-containing gaskets and valve packing in steam system components from Garlock
