Facility Overview: Amoco Chemical Company in Joliet, Illinois

A Major Petrochemical Operation in Will County

The Amoco Chemical Company facility in Joliet, Illinois, was a large-scale petrochemical operation in Will County that reportedly processed petroleum derivatives and employed thousands of skilled-trades workers over several decades. As a subsidiary of the Standard Oil Company of Indiana — later Amoco Corporation — the plant ranked among the largest petroleum and petrochemical operations in the Midwest.

The facility reportedly housed the complex process systems inherent to large-scale petrochemical production:

High-temperature steam systems for distillation and reactor heating
High-pressure piping networks carrying superheated fluids and gases
Boilers and furnaces generating steam for process heat and power
Heat exchangers and condensers requiring extensive thermal insulation
Turbines and compressors with demanding sealing requirements
Electrical infrastructure requiring fireproofing in high-heat environments

Peak Asbestos Use: 1940s Through the Early 1980s

American industrial facilities — including plants like the Amoco Joliet operation — reportedly used asbestos-containing materials at peak rates from the 1940s through the early 1980s. Petrochemical plant operators favored asbestos-containing materials because they:

Insulated against temperatures exceeding 1,000 degrees Fahrenheit
Resisted chemical corrosion
Maintained mechanical flexibility under thermal cycling
Cost far less than synthetic alternatives available at the time

Federal regulation began arriving in the 1970s. OSHA issued its first asbestos standard in 1971; the EPA classified asbestos as a hazardous air pollutant under the Clean Air Act. Neither development ended industrial asbestos use overnight:

Enforcement remained inconsistent across industry sectors
Legacy materials stayed in place for years or decades after installation
Workers continued encountering asbestos-containing materials during maintenance and renovation well into the 1980s, 1990s, and beyond

Workers at facilities like the Amoco Chemical Joliet plant who labored there during construction, operation, modernization, and maintenance shutdowns may have been exposed to asbestos-containing materials across all of those decades. The shared Mississippi River industrial corridor connecting Missouri and Illinois underscores how interconnected industrial exposure risks were — and remain — across this region.

Asbestos-Containing Materials Allegedly Present at This Facility

Pipe and Vessel Insulation

Thermal pipe insulation was among the most pervasive asbestos-containing materials at large chemical plants. Pre-formed pipe covering and block insulation containing chrysotile, amosite, or crocidolite fiber types are alleged to have been applied to steam lines, process lines, and vessel surfaces throughout the Joliet plant.

Products from the following manufacturers are alleged to have been present at comparable petrochemical facilities and may have been present at this facility:

Johns-Manville Corporation — Kaylo and Thermobestos pipe coverings
Owens-Corning Fiberglas / Owens-Illinois — asbestos-containing thermal insulation products
Armstrong World Industries — pipe insulation and block materials
Combustion Engineering — specialized boiler and process insulation
Eagle-Picher Industries — asbestos-containing thermal protection products

Similar materials are documented at comparable regional facilities including Granite City Steel (Granite City, IL), Monsanto Chemical (Sauget, IL), and the Portage des Sioux power plant (Portage des Sioux, MO).

Boiler and Turbine Insulation Systems

Boilers operating at extreme temperatures required extensive insulation systems that reportedly included:

Block insulation products from Johns-Manville and Owens-Corning/Owens-Illinois
Cement-based materials allegedly containing asbestos fibers
Blanket insulation and sprayed fireproofing materials
Lagging products from Armstrong World Industries and Combustion Engineering

Workers who cut, fitted, installed, repaired, or removed boiler insulation faced the highest fiber-release risk of any task in the plant. Disturbing friable insulation releases asbestos fibers directly into the breathing zone.

High-Temperature Gaskets and Packing Materials

Flanged pipe connections, valve bonnets, and pump housings throughout the plant required sealing materials rated for high-temperature, high-pressure service. Compressed asbestos sheet gaskets and braided asbestos rope packing are alleged to have been in widespread use throughout the facility.

Workers who performed this work may have been exposed to asbestos-containing materials from:

Garlock Sealing Technologies — compressed asbestos sheet and spiral-wound gasket products
John Crane Inc. — mechanical seal and gasket materials
A.W. Chesterton Company — packing and sealing products
Flexitallic Gasket Company — asbestos-containing spiral-wound gaskets

Routine exposure tasks included cutting gaskets from sheet stock to fit flanges, installing spiral-wound gaskets on high-pressure connections, and pulling and replacing valve packing with picks and scrapers — each of which can release respirable fibers.

Refractory and Fireproofing Materials

High-temperature process equipment and structural steel reportedly required specialized fire and heat protection that may have included:

Refractory insulating cements, castables, and brick in furnaces, fired heaters, and process equipment, reportedly manufactured by Johns-Manville and Combustion Engineering
Sprayed asbestos-containing fireproofing applied to structural steel during plant construction and modernization
Monokote and comparable sprayed fireproofing systems alleged to have contained asbestos fibers

Building Materials: Floor Tiles, Ceiling Systems, and Roofing

The plant reportedly contained asbestos-containing materials throughout its constructed spaces, including:

Vinyl asbestos floor tiles in control rooms, laboratories, and administrative areas
Asbestos-containing ceiling tiles from manufacturers including Armstrong World Industries
Roofing materials allegedly containing asbestos from Georgia-Pacific and Celotex
Transite board — a calcium silicate-asbestos composite — in building structures and equipment enclosures

Similar products are documented at comparable Illinois facilities including Shell Oil/Roxana Refinery (Wood River, IL) and Clark Refinery (Wood River, IL).

Electrical Infrastructure

Electrical systems in older industrial facilities reportedly incorporated asbestos-based materials, including:

Asbestos cloth, rope, and board used as electrical insulation
Arc chutes in switchgear allegedly containing asbestos fibers
Switchgear components from manufacturers including Crane Co. alleged to have contained asbestos-containing materials
Older wiring insulation throughout the facility

Electricians working in these areas may have been exposed during installation, routine repair, and troubleshooting work.

Friction Materials and Miscellaneous Products

Additional asbestos-containing products reportedly present at comparable industrial facilities included:

Brake linings and clutch components on plant vehicles and mobile equipment
Asbestos cloth used in heat-protective applications and thermal barriers
Packing and gasket materials in miscellaneous mechanical systems throughout the plant

Which Trades May Have Been Exposed

Insulators: Highest-Risk Occupational Group

Heat and frost insulators — also called asbestos workers — carry some of the highest documented rates of asbestos-related disease of any skilled trade. Members of Heat and Frost Insulators Local 1 (St. Louis, MO) who worked at the Amoco Joliet facility may have spent careers:

Installing and removing asbestos-containing pipe insulation products from Johns-Manville and Owens-Corning/Owens-Illinois
Replacing block insulation, boiler lagging, and other thermal products allegedly containing asbestos fibers
Cutting and sawing pre-formed insulation to fit irregular surfaces
Mixing and applying asbestos-containing cements and fireproofing compounds
Removing old insulation that had become friable with age and mechanical stress

Each of those tasks can release high concentrations of airborne asbestos fibers directly into the worker’s breathing zone.

Pipefitters and Steamfitters

Pipefitters working through Plumbers and Pipefitters UA Local 562 (St. Louis, MO) may have been exposed to asbestos-containing materials throughout the facility. Their work may have brought them into direct contact with:

Asbestos-containing gaskets from Garlock Sealing Technologies and comparable manufacturers, cut from sheet stock at the job site
Braided asbestos rope packing removed with picks and scrapers during valve and pump maintenance
Asbestos-insulated pipe systems in confined spaces where fiber concentrations could reach dangerous levels
Insulation products from Johns-Manville, Owens-Corning, and Armstrong World Industries encountered during system repair

Pipefitters working during plant maintenance shutdowns — turnarounds — may have faced elevated exposure when multiple trades worked simultaneously in close quarters.

Boilermakers

Boilermakers who built, maintained, and repaired boilers, pressure vessels, heat exchangers, and related equipment may have worked in environments heavily contaminated with asbestos-containing materials from manufacturers including Combustion Engineering and Johns-Manville. That work potentially required:

Removing and replacing refractory and insulating materials allegedly containing asbestos fibers
Working inside boiler fireboxes, furnaces, and vessels lined with asbestos-containing products
Coordinating closely with insulators who applied and removed asbestos-containing lagging on boiler shells and steam drums
Handling friable materials during demolition and equipment renovation

Electricians

Electricians who maintained electrical infrastructure throughout the facility may have encountered:

Asbestos-containing electrical insulation materials from Crane Co. and comparable manufacturers
Asbestos board used as backing material in electrical panels and switchgear enclosures
Asbestos dust released by insulation work performed by Heat and Frost Insulators working in adjacent areas
Older asbestos-containing wire and cable that shed fibers when pulled through conduit

Maintenance Mechanics and Millwrights

These workers repaired rotating machinery, replaced pump and valve components, and performed general plant maintenance. Work with gaskets from Garlock Sealing Technologies and comparable manufacturers, and with insulated equipment across the plant, may have produced substantial asbestos exposure — particularly during:

Disassembly of flanged connections containing compressed asbestos sheet gaskets
Removal of old packing from valves and pumps using hand tools
Equipment repair requiring disturbance of thermal insulation
Routine maintenance shutdowns when work scope was heaviest

Construction Workers, Ironworkers, and Laborers

During original plant construction and subsequent expansions, ironworkers, carpenters, and laborers may have worked in environments where:

Sprayed asbestos-containing fireproofing materials — including Monokote and comparable products — were applied to structural steel overhead
Building and renovation work disturbed asbestos-containing materials already installed in
