The Ethyl Corporation Sauget Facility

Sauget, Illinois: An Industrial Zone Built for Heavy Chemistry

Sauget, Illinois — incorporated in 1926 as “Monsanto” before being renamed in 1967 — was created specifically to attract heavy chemical and manufacturing operations. Situated on the east bank of the Mississippi River directly across from St. Louis, Sauget became one of the most concentrated industrial corridors in the central United States.

Major industrial tenants in the Sauget corridor reportedly included:

Monsanto Chemical — petrochemical and chemical production
Cerro Copper — copper refining and fabrication
Chase Brass and Copper Company — specialty brass and copper manufacturing
Shell Oil / Roxana Refinery — corridor-area refining operations
Ethyl Corporation — chemical manufacturing and petroleum additive production

These facilities shared utility infrastructure, contractor workforces, and supply chains. Workers routinely crossed between sites — which means exposure risk at one facility often extended across the entire corridor.

Ethyl Corporation: What They Made and When

Ethyl Corporation was founded in 1923 as a joint venture between General Motors and Standard Oil of New Jersey. The company built significant chemical manufacturing operations in the Sauget corridor as part of its national production network. Primary products included:

Tetraethyl lead (TEL) — a gasoline octane additive
Petroleum additives and specialty chemicals
Aluminum alkyls
Industrial chemical products

The period from approximately the 1940s through the early 1980s represents peak production at Sauget — and the era when asbestos-containing materials were most heavily integrated into American industrial facilities. Workers at the Ethyl Corporation plant during those decades may have been exposed to asbestos-containing materials throughout their working lives.

Why Chemical Plants Were Saturated with Asbestos-Containing Materials

Chemical manufacturing facilities operated systems that demanded asbestos-containing insulation, gaskets, and protective materials at every turn:

High-temperature industrial processes requiring pipe insulation and equipment lagging
Steam generation and distribution systems using boilers, steam lines, and heat exchangers
Reactors and distillation columns requiring thermal insulation
Turbines, pumps, and compressors requiring gaskets, packing, and valve insulation
Piping networks transporting caustic, corrosive, and high-temperature chemical streams

As was standard industrial practice for most of the twentieth century, each of these systems allegedly incorporated asbestos-containing materials from manufacturers including Johns-Manville Corporation, Owens-Illinois, Armstrong World Industries, and Celotex Corporation.

Why Manufacturers Are Liable — Not Just the Facility

The Engineering Logic That Brought Asbestos Into Every Plant

Asbestos is a naturally occurring silicate mineral with properties that made it the default engineering choice for industrial insulation:

Withstands temperatures exceeding 1,000°F without combusting
Stronger per unit diameter than steel wire
Resists acids, alkalis, and solvents
Electrically non-conductive
Inexpensive and abundantly available

For a chemical plant processing volatile compounds at high temperatures, asbestos-containing materials were the accepted engineering standard. The use of asbestos-containing materials is not, by itself, the legal basis for a claim. Liability arises because manufacturers deliberately concealed known health hazards from the workers using their products — for decades.

The Concealment That Creates Legal Liability

Internal documents produced through decades of litigation establish that major asbestos product manufacturers knew their products cause mesothelioma, asbestosis, and lung cancer — and continued marketing them without adequate warnings. Companies documented as possessing this knowledge include:

Johns-Manville Corporation — insulation products, pipe lagging, asbestos cement, refractory materials
Owens-Corning Fiberglas Corporation — fiber-reinforced insulation products
Owens-Illinois — manufacturer of Kaylo calcium silicate insulation containing asbestos
Armstrong World Industries — insulation, flooring, and building materials
Combustion Engineering — boiler systems and components with asbestos-containing insulation and gaskets
Garlock Sealing Technologies — compressed asbestos sheet gaskets and packing
A.W. Chesterton Company — asbestos-containing packing and sealing products
John Crane, Inc. (formerly Crane Packing) — asbestos pump and valve packing

These manufacturers knew their products were killing workers. They chose silence over warning labels. That deliberate concealment — documented in their own internal records — is the legal foundation for asbestos personal injury claims.

Who Was at Risk at Ethyl Corporation and the Sauget Corridor

Workers in the following trades and roles may have experienced elevated asbestos exposure risk at the Ethyl Corporation facility or at adjacent Sauget corridor operations:

Insulators and Heat & Frost Insulators — pipe insulation removal and installation
Pipefitters and Plumbers — gasket and packing replacement, valve maintenance
Boilermakers — steam system maintenance and repair
Electricians — electrical system maintenance and panel work
General maintenance workers and mechanics
Contractors and temporary workers rotating through multiple industrial sites
Facility operators and engineers

The corridor’s shared contractor workforce is significant: a worker who spent only a portion of his career at Ethyl Corporation may also have accumulated exposure at Monsanto Chemical, Cerro Copper, or other Sauget facilities — all potentially actionable.

Asbestos-Containing Materials Allegedly Present at the Ethyl Corporation Facility

The product categories and manufacturers described below are consistent with what has been documented at comparable chemical manufacturing facilities of the same era. Workers at the Ethyl Corporation plant may have been exposed to asbestos-containing materials from these and similar sources.

Pipe and Equipment Insulation

High-temperature pipe insulation was among the most common exposure sources in chemical processing facilities. Asbestos-containing pipe insulation products reportedly used at facilities like the Ethyl Corporation plant may have included:

Johns-Manville Corporation — calcium silicate and asbestos block insulation for high-temperature industrial pipe systems
Owens-Illinois Kaylo — calcium silicate pipe insulation sections containing asbestos, widely distributed across Midwest industrial facilities
Armstrong World Industries — asbestos-containing thermal pipe insulation for industrial applications
Fibreboard Corporation — asbestos pipe and block insulation
Celotex Corporation — asbestos-containing insulation for industrial piping
Keene Corporation — asbestos insulation materials

Workers who cut, fit, applied, or removed pipe insulation were reportedly among those at highest risk — these tasks released substantial quantities of airborne asbestos fibers directly into the breathing zone. Insulators and pipefitters from Heat and Frost Insulators Local 1 (St. Louis, MO) and Plumbers and Pipefitters UA Local 562 (St. Louis, MO) may have performed insulation work at the Ethyl Corporation facility or at adjacent Sauget sites.

Boiler Insulation and Refractory Materials

Industrial boilers at the Ethyl Corporation facility generated steam for process heating, distillation, and power generation. These units were reportedly insulated with asbestos-containing materials, potentially including:

Asbestos block insulation applied to boiler exteriors and steam drums, allegedly from Johns-Manville, Armstrong World Industries, or Celotex
Asbestos-containing refractory cement used in boiler fireboxes and flue passages
Asbestos rope and wicking used to seal boiler doors, manholes, and inspection ports
Asbestos cloth and tape used to wrap flanges, valves, and irregular fittings

Boilermakers who worked on these units — particularly during maintenance, repair, and turnaround work — may have been exposed to high concentrations of airborne asbestos fibers. Comparable exposure patterns have been documented at other Sauget corridor operations and at Ameren UE power generation facilities throughout the region.

Gaskets and Packing Materials

Gaskets and valve packing were among the most pervasive asbestos exposure sources in chemical plants. Every flanged pipe joint, pressure vessel hatch, pump seal, and control valve potentially contained asbestos-based sealing materials.

Asbestos-containing gasket and packing products allegedly present at the facility may have included:

Garlock Sealing Technologies — compressed asbestos sheet gaskets and packing
John Crane, Inc. (formerly Crane Packing) — asbestos pump and valve packing, including Superex asbestos packing products
A.W. Chesterton Company — asbestos-containing packing and sealing products for pumps and valves
Flexitallic — spiral-wound gaskets containing asbestos filler
Victaulic Corporation — pipe coupling and connection materials potentially containing asbestos-containing components

Pipefitters and maintenance mechanics — including members of Plumbers and Pipefitters UA Local 562 — who removed and replaced gaskets and packing using wire brushes, scrapers, and grinders to clear old material from flanges may have been exposed to asbestos fibers as a direct result of these routine tasks.

Insulating Cement and Spray-Applied Insulation

Insulating cements applied wet to irregular surfaces typically contained 30–70% asbestos fiber by weight when manufactured before the mid-1970s. Workers applied these products to elbows, fittings, and equipment surfaces where pre-formed insulation sections could not be fitted. Products may have included:

Johns-Manville asbestos insulating cement
Armstrong asbestos-containing joint and mastic cements
Celotex insulating cement products

Spray-applied asbestos-containing insulation was also reportedly used in some industrial settings to fireproof structural steel and insulate equipment at facilities in the Sauget corridor.

Electrical Insulation Materials

Electrical switchgear, panel boards, arc chutes, and wiring systems in industrial facilities of this era frequently incorporated asbestos-containing materials for heat resistance and arc suppression. Electricians who cut or drilled into asbestos-containing electrical panels, or who replaced arc chutes in circuit breakers, may have been exposed to asbestos-containing materials from manufacturers including:

Square D Company — electrical switchgear and distribution equipment with potentially asbestos-containing components

Your Legal Options: Missouri Mesothelioma Claims

If you have been diagnosed with mesothelioma or an asbestos-related disease and worked at the Ethyl Corporation facility or in the broader Sauget industrial corridor, you may be entitled to substantial compensation. Missouri law provides multiple paths to recovery:

State court litigation — Missouri courts, including St. Louis City Circuit Court, have a well-established record of mesothelioma verdicts and settlements. St. Louis has historically been one of the most plaintiff-favorable venues in the country for asbestos cases.

Asbestos bankruptcy trust fund claims — Dozens of major asbestos manufacturers, including Johns-Manville, Owens-Illinois, Armstrong, Celotex, and Fibreboard, have filed for bankruptcy and established compensation trusts. These trusts hold billions of dollars specifically for workers and families harmed by their products. Claims can often be filed simultaneously with active litigation.
