Former Workers and Their Families Face Real Health Risks

The Huntsman Chemical Corporation facility in Peru, Illinois may have exposed hundreds of workers to asbestos-containing materials over several decades. If you worked at this plant — or if a family member did — and you have since been diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease, you may have legal claims that can recover compensation, medical coverage, and financial security for your family.

A qualified mesothelioma lawyer Missouri can evaluate your case, identify every responsible defendant, and pursue every available source of recovery. This article covers the Peru facility’s operations, which trades and job roles may have encountered asbestos-containing materials, what diseases result from that exposure, and what legal options are available.

The Huntsman Chemical Peru, Illinois Facility

History and Industrial Operations

The Peru, Illinois facility sits in LaSalle County along the Illinois River corridor — part of a broader industrial base that made the region a major chemical and manufacturing center throughout the twentieth century. The facility has roots in prior chemical manufacturing operations dating back to the early and mid-twentieth century. Huntsman Corporation, a global specialty chemicals manufacturer, subsequently acquired and operated the site as part of its Illinois Valley operations.

Chemical manufacturing plants of this type and era ran:

Extensive piping systems carrying hot process fluids
High-pressure reactors and pressure vessels
Boilers and steam distribution systems
Heat exchangers and distillation columns
Process equipment operating at high temperatures and pressures

Every one of these systems required thermal insulation, gaskets, packing materials, and other products that manufacturers routinely produced with asbestos-containing materials. Those materials remained in place for decades, deteriorated, and were disturbed repeatedly during routine maintenance — creating the conditions for asbestos exposure that has driven litigation across the Illinois and Missouri industrial corridor for forty years.

Why Chemical Manufacturers Used Asbestos-Containing Materials

Asbestos use in chemical manufacturing was deliberate and industry-wide:

Thermal insulation: Asbestos-containing pipe insulation, block insulation, and blanket insulation products covered steam lines, process piping, and reaction vessels operating above several hundred degrees Fahrenheit
Fire and heat resistance: Asbestos-containing fireproofing was sprayed or applied to structural steel and equipment supports throughout these facilities
Gaskets and packing: Asbestos-containing compressed gaskets and valve packing sealed virtually every flanged connection and valve in the plant
Boiler applications: Boiler bodies, steam drums, headers, and associated distribution piping were insulated with asbestos-containing materials
Equipment insulation: Pumps, compressors, turbines, and rotating equipment were insulated and fitted with asbestos-containing components
Electrical insulation: Certain wiring, panels, and electrical equipment contained asbestos-based insulating materials

This pattern held across American chemical manufacturing plants from roughly the 1920s through the 1980s, when regulatory action and growing medical evidence began forcing asbestos out of new construction.

Asbestos-Containing Products Reportedly Present at the Peru Facility

Based on the types of operations conducted at chemical manufacturing facilities of this type and era, workers at the Peru facility may have been exposed to asbestos-containing materials from major producers of that period. Products commonly alleged in litigation involving similar facilities include:

Thermal Insulation Products

Pipe insulation and block insulation reportedly manufactured by Johns-Manville, Owens-Illinois, and Armstrong World Industries — products frequently referenced in NESHAP abatement records and OSHA inspection data from comparable chemical manufacturing facilities
Calcium silicate insulation blocks with asbestos binders, used on high-temperature piping and vessels
Magnesia-based pipe insulation (85% magnesia formulation), widely used on steam lines and high-temperature process equipment through at least the 1970s
Asbestos blankets and wrap materials around expansion joints, flanges, and irregular equipment surfaces, allegedly supplied by Johns-Manville and Owens-Illinois

Gaskets and Packing Materials

Compressed asbestos sheet gaskets allegedly manufactured by Garlock Sealing Technologies, John Crane, and Flexitallic — materials routinely encountered during chemical plant turnarounds
Asbestos rope packing and braided valve packing used to seal pump shafts, valve stems, and rotating equipment
Spiral wound gaskets with asbestos filler in high-pressure flanged connections throughout process systems

Boiler and Refractory Materials

Boiler insulation and lagging materials reportedly containing asbestos-containing insulating cements, applied to boiler surfaces, steam drums, and headers
Refractory cements and mortars with asbestos binders, used in furnaces and high-temperature process equipment
Asbestos-containing insulating cement (finishing cement) allegedly applied over pipe insulation by Heat and Frost Insulators Local 1 and affiliated local unions during maintenance operations

Fireproofing and Building Materials

Sprayed-on asbestos-containing fireproofing applied to structural steel members, standard in industrial construction through the early 1970s
Asbestos-containing floor tiles, ceiling tiles, and wall panels in control rooms, maintenance shops, and administrative areas — products including Gold Bond and Sheetrock brand materials that reportedly contained asbestos-containing materials
Asbestos-containing roofing materials and exterior cladding on industrial buildings, allegedly manufactured by Celotex and Georgia-Pacific

Electrical Materials

Asbestos-containing wire insulation used in certain industrial wiring applications
Arc chutes and electrical panel components with asbestos-based insulating materials in switchgear and motor control centers

Friction Products

Asbestos-containing brake linings on industrial vehicles, forklifts, and overhead cranes used throughout the facility

Who May Have Been Exposed: Trades and Job Classifications at Risk

Asbestos-related disease does not affect only workers who directly handled asbestos-containing materials. Research consistently shows that bystander exposure — inhaling fibers released by nearby workers — can cause mesothelioma and other asbestos-related diseases. At a chemical manufacturing facility like the Peru plant, multiple trades and job classifications may have been exposed.

Insulators (Asbestos Workers)

Insulators employed at this facility, including members of Heat and Frost Insulators Local 1 (St. Louis, MO) and Heat and Frost Insulators Local 27 (Kansas City, MO), are among the trades most historically associated with asbestos exposure in industrial settings. Workers in this classification reportedly performed tasks that may have released substantial asbestos fiber concentrations:

Removing old asbestos-containing pipe insulation during maintenance or turnaround activities
Cutting, shaping, and applying new asbestos-containing insulation materials — including products allegedly manufactured by Johns-Manville and Owens-Illinois — to pipes, vessels, and equipment
Mixing and applying asbestos-containing insulating cements to finished insulation surfaces
Working in enclosed spaces where asbestos dust accumulated
Installing and removing asbestos-containing blankets and wrap materials around flanges and expansion joints

Pipefitters and Steamfitters

Pipefitters, including members of Plumbers and Pipefitters UA Local 562 (St. Louis, MO) and UA Local 268 (Kansas City, MO), are alleged to have had frequent contact with asbestos-containing materials through:

Breaking flanged connections and disturbing existing asbestos-containing gaskets allegedly manufactured by Garlock Sealing Technologies and other gasket producers
Removing and replacing asbestos-containing valve packing during maintenance
Working alongside Heat and Frost Insulators members who were simultaneously removing or applying asbestos-containing pipe insulation
Installing or removing insulated pipe spools and fittings incorporating asbestos-containing materials
Performing hot work on piping systems that required removal of surrounding asbestos-containing insulation

Boilermakers

Boilermakers at the Peru facility may have been exposed through:

Maintenance and repair of boilers reportedly insulated with asbestos-containing magnesia and calcium silicate products
Work inside boiler fireboxes and pressure vessels where asbestos-containing refractory materials were allegedly present
Cutting or grinding through asbestos-containing insulation to reach boiler components
Weld repairs on boiler components surrounded by asbestos-containing lagging

Electricians

Electricians working at the facility may have been exposed through:

Working in electrical rooms, motor control centers, and switchgear areas allegedly containing asbestos-based insulating materials
Running conduit and wiring through walls, floors, and ceilings with asbestos-containing construction materials allegedly manufactured by Owens-Illinois and Georgia-Pacific
Working near other trades performing asbestos-disturbing work during plant turnarounds and maintenance shutdowns
Handling asbestos-containing wire insulation and electrical components

Maintenance Mechanics and Millwrights

General maintenance workers and millwrights reportedly encountered asbestos-containing materials through:

Routine maintenance on pumps and compressors requiring removal of asbestos-containing gaskets and packing materials
Equipment overhauls requiring removal of asbestos-containing insulation — allegedly manufactured by Johns-Manville and Armstrong World Industries — to access underlying machinery
Working in maintenance shops where asbestos-contaminated clothing and equipment were regularly present
Fabricating and installing equipment incorporating asbestos-containing components

Operating Engineers and Process Operators

Process operators and control room personnel may have been exposed through:

Bystander exposure during maintenance operations conducted while the plant ran partially or fully operational
Working in control rooms and equipment buildings with asbestos-containing construction and insulating materials
Routine rounds through process areas where damaged or deteriorating asbestos-containing insulation may have been releasing fibers

Outside Contractors and Construction Workers

Chemical manufacturing facilities of this type regularly hosted major construction and expansion projects, along with periodic turnarounds drawing large numbers of outside contractors. Workers employed by construction contractors, insulation contractors, mechanical contractors, and specialty subcontractors who performed work at the Peru facility may have been exposed to asbestos-containing materials and may have viable legal claims regardless of whether they were directly employed by Huntsman or its predecessors.

Family Members: Secondary (Take-Home) Exposure

Family members of workers employed at the Peru facility represent a frequently overlooked category of potential victims. Medical literature has documented “take-home” or “para-occupational” exposure, where asbestos fibers carried home on a worker’s clothing, hair, skin, and tools are subsequently inhaled by household members — most commonly spouses who laundered contaminated work clothing.

Family members who regularly laundered a worker’s clothing from the Peru facility, or who had regular contact with a worker returning home in contaminated work clothes, may have inhaled asbestos fibers released from insulation products allegedly manufactured by Johns-Manville and Owens-Illinois. Those family members face real risk of asbestos-related disease, including mesothelioma, and may have independent legal claims.

Mesothelioma: The Most Serious Asbestos Cancer

Mesothelioma is a malignant cancer that develops in the mesothelium — the thin membrane lining the lungs (pleura), abdomen (peritoneum), or heart (pericardium). The scientific and medical consensus is unequivocal: asbestos causes mesothelioma. No safe level of asbestos exposure exists.

Key facts about mesothelioma:

Long latency period: Mesothelioma typically does not appear until 20 to 50 years after initial exposure. Workers who may have been exposed to asbestos-containing materials at the Peru facility in the 1960s, 1970s, and 1980s may only now be receiving diagnoses.
Aggressive disease course: Median survival after diagnosis remains poor without aggressive treatment. Early legal action preserves your options and your family’s financial security.
