Who May Have Been Exposed to Asbestos at Hercules, Inc. - Aqualon?

Extensive use of asbestos-containing materials for insulation and structural components suggests various tradespeople working at Hercules, Inc. - Aqualon may have been exposed. These include:

Insulators: Members of unions like Heat and Frost Insulators Local 1 (St. Louis, MO) or Local 27 (Kansas City, MO) reportedly handled and installed asbestos-containing insulation. This included Thermobestos, Kaylo, or Aircell on pipes, boilers, tanks, and equipment. Their work often involved cutting, fitting, and removing these materials, which could release substantial amounts of asbestos fibers.
Pipefitters: Members of Plumbers and Pipefitters UA Local 562 (St. Louis, MO) or Local 268 (Kansas City, MO) may have worked closely with asbestos-insulated pipes. They often needed to remove or disturb insulation from Johns-Manville or Owens Corning to access piping for repairs or modifications. Similar activities were common at sites like Granite City Steel in Illinois, Monsanto Chemical in St. Louis, or the Shell Oil / Roxana Refinery in Illinois.
Boilermakers: Members of unions such as Boilermakers Local 27 (St. Louis, MO) were allegedly involved in the construction, maintenance, and repair of boilers. Boilers frequently used asbestos-containing materials such as Superex from Johns-Manville or Unibestos from Combustion Engineering for insulation. This work would have mirrored tasks at power plants like the Rush Island Energy Center in Missouri.
Electricians: May have encountered asbestos in wiring insulation, electrical panels, and conduit systems, especially during renovation or repair work involving older electrical components.
Maintenance Workers: General maintenance staff performing routine upkeep, repairs, or inspections throughout the plant may have disturbed ACMs from manufacturers like Armstrong World Industries (floor tiles/adhesives) or Garlock Sealing Technologies (gaskets) without proper protective measures.
Demolition Workers: Those involved in dismantling structures or equipment containing asbestos, such as Transite panels from Celotex or Georgia-Pacific, would have faced a high risk of exposure.
Construction Workers: Any workers involved in the original construction or later renovations of buildings and systems where ACMs, like asbestos cement products or block insulation, were installed.
Laborers: General laborers assisting various trades, potentially including those working alongside union members from Plumbers and Pipefitters UA Local 562, may have been present in areas where asbestos fibers were released.

Family members of these workers may also be at risk through “take-home” exposure, a known route of exposure for Missouri and Illinois families. Asbestos fibers were unknowingly carried home on clothing, tools, or hair. An asbestos cancer lawyer St. Louis can evaluate your potential exposure and legal options.

Diseases Caused by Asbestos Exposure

Asbestos fiber exposure, even for a short period, can lead to serious and often fatal diseases. These diseases typically have a long latency period, and symptoms may not appear for 10 to 50 years after initial exposure. Primary diseases associated with asbestos exposure include:

Mesothelioma: A rare, aggressive cancer affecting the lining of the lungs (pleural mesothelioma), abdomen (peritoneal mesothelioma), or heart (pericardial mesothelioma). Asbestos exposure almost exclusively causes it.
Asbestosis: A chronic, non-cancerous lung disease featuring scarring of the lung tissue, leading to shortness of breath, coughing, and reduced lung function.
Lung Cancer: Asbestos exposure significantly increases the risk of developing lung cancer, particularly in individuals who also smoke.
Other Cancers: Studies link asbestos exposure to an increased risk of cancers of the larynx, pharynx, stomach, and colorectal region.
Pleural Plaques: Thickening and calcification of the pleura (lining of the lungs), indicating asbestos exposure and potentially leading to impaired lung function.

Litigation Landscape

Workers at industrial manufacturing facilities like Hercules’ Aqualon operation faced exposure to asbestos-containing products used in pumps, gaskets, valve packing, insulation, and equipment seals. Litigation arising from such facilities has historically named manufacturers including Crane Co., Garlock, Eagle-Picher, W.R. Grace, Combustion Engineering, Babcock & Wilcox, and Johns-Manville as defendants in documented asbestos cases.

Many of these manufacturers have since established bankruptcy trust funds, making compensation accessible without trial. Relevant trusts include the Crane Co. Asbestos Settlement Trust, Garlock Sealing Technologies Trust, Eagle-Picher Industries Trust, W.R. Grace Asbestos Compensation Trust, and the Babcock & Wilcox Industries Trust. Workers who developed mesothelioma, lung cancer, or asbestosis following exposure at this facility may be eligible to file claims with one or more of these trusts, depending on which specific asbestos-containing products were present in their work area.

Claims arising from chemical and manufacturing plants of this era have been documented in publicly filed litigation, reflecting the widespread use of asbestos in industrial settings during the 1980s and 1990s. Workers often had direct contact with asbestos fibers during equipment maintenance, repairs, and decontamination procedures—exposures that may not manifest as disease until decades later.
