Foster Wheeler Process Heaters: Asbestos Exposure in Refineries and Chemical Plants

Product Description

Foster Wheeler Corporation was one of the most prominent engineering and manufacturing firms in twentieth-century American industry. The company designed, fabricated, and installed large-scale thermal processing equipment—most notably process heaters—used extensively in petroleum refineries, chemical processing plants, and petrochemical facilities throughout the United States and internationally. These units, also called fired heaters or furnaces, were central to industrial operations such as crude oil distillation, catalytic cracking, hydrocracking, and chemical synthesis. Foster Wheeler’s process heaters were considered industry-standard equipment for decades, appearing in facilities operated by major oil companies and chemical manufacturers from roughly the mid-twentieth century through the late 1980s.

Beyond the refinery and chemical plant sectors, Foster Wheeler also operated in marine and boiler markets, manufacturing steam-generating systems for naval and commercial vessels as well as utility and industrial boilers. The breadth of the company’s manufacturing portfolio meant that its equipment—and the hazardous materials incorporated into that equipment—reached workers across multiple industries and trades. Process heaters, in particular, were among Foster Wheeler’s signature products, and they were built and maintained during an era when asbestos was routinely specified as a thermal insulation material in high-temperature industrial systems.

Asbestos Content

Process heaters operate at extreme temperatures, with radiant sections and convection coils routinely subjected to temperatures exceeding 1,000 degrees Fahrenheit. To manage those temperatures, control heat loss, and protect structural components, manufacturers of this era incorporated asbestos-containing materials throughout heater construction. Litigation records document that Foster Wheeler process heaters were manufactured with asbestos insulation applied to heater walls, firebox linings, refractory panels, pipe and tubing insulation, and associated flanges and fittings.

Asbestos-containing materials used in and around process heaters typically included:

  • Refractory and block insulation applied to firebox interiors and outer casing walls
  • Asbestos rope and gaskets used at access doors, burner ports, and expansion joints
  • Pipe covering and block insulation on process tubes, inlet and outlet headers, and interconnecting piping
  • Asbestos cloth and blankets used during construction, maintenance, and repair operations
  • Finishing cements and mastics applied over block insulation on piping and structural surfaces

Plaintiffs alleged that asbestos was specified in original equipment designs and that Foster Wheeler either incorporated these materials directly during fabrication or provided engineering specifications that required asbestos-containing products to be installed by contractors and workers at job sites. Litigation records document that this content was present in equipment supplied across multiple decades of production.

How Workers Were Exposed

Industrial workers in refineries and chemical plants faced asbestos exposure through multiple pathways over the operational life of Foster Wheeler process heaters. Exposure occurred during initial construction and commissioning of facilities, during routine maintenance and turnaround operations, and during major repairs or decommissioning activities.

Construction and installation workers were among those at risk during the fabrication and erection of new heater units. Insulators, pipefitters, millwrights, and boilermakers worked in proximity to large quantities of asbestos insulation materials as heaters were assembled, lined, and brought into service. Cutting, fitting, and applying block insulation and refractory materials to heater fireboxes and process tube bundles generated substantial airborne fiber concentrations in enclosed or poorly ventilated work areas.

Maintenance and turnaround workers faced repeated and often intensive exposures throughout the service life of process heaters. Petroleum refineries and chemical plants typically scheduled periodic shutdowns—known as turnarounds—during which equipment including process heaters was inspected, repaired, and relined. Workers who removed deteriorated refractory linings, stripped old pipe insulation, replaced gaskets, or worked near others performing these tasks were exposed to asbestos fibers released from degraded materials. Litigation records document that turnaround work was among the highest-exposure activities in refinery environments.

Boilermakers and pipefitters who regularly serviced burner assemblies, expansion joints, and high-temperature piping connections on process heaters were exposed each time access panels were opened and disturbed insulation released fibers. Plaintiffs alleged that fiber release during routine maintenance was foreseeable and that adequate warnings were not provided to workers or their employers.

Marine workers were similarly affected through Foster Wheeler’s boiler and marine product lines. Shipyard workers, Navy personnel, and merchant mariners who worked aboard vessels equipped with Foster Wheeler boilers faced exposure conditions comparable to those documented in land-based refinery settings.

In all these environments, asbestos exposure was often bystander exposure—workers who were not directly handling insulation materials could still inhale fibers released by nearby trades. Industrial workers generally, including operators, supervisors, and laborers who were present during maintenance activities, have been identified in litigation as having been exposed through proximity to disturbed asbestos-containing components of process heater systems.

Foster Wheeler’s asbestos liability has been the subject of extensive civil litigation. Plaintiffs in these cases have included refinery workers, chemical plant employees, boilermakers, pipefitters, insulators, and other industrial tradespeople who alleged occupational asbestos exposure from Foster Wheeler equipment. Litigation records document claims involving mesothelioma, lung cancer, asbestosis, and other asbestos-related diseases.

Current litigation status: Foster Wheeler LLC and its corporate successors continue to be named as defendants in asbestos personal injury lawsuits filed in state and federal courts. Plaintiffs alleged that Foster Wheeler knew or should have known of the hazards of asbestos in its products and failed to provide adequate warnings to downstream workers and users. Claims have been filed in jurisdictions with active asbestos dockets, including courts in Texas, Louisiana, California, New Jersey, and Delaware, among others.

No dedicated trust fund: As of available records, Foster Wheeler has not established a dedicated asbestos bankruptcy trust under Section 524(g) of the U.S. Bankruptcy Code in the manner of some other former asbestos product manufacturers. This means that claims against Foster Wheeler entities are typically pursued through direct civil litigation rather than through a structured trust claims process.

What affected workers should do: Individuals who worked in refineries, chemical plants, or shipyards and were exposed to Foster Wheeler process heaters or boilers—or who were employed in proximity to maintenance, installation, or repair of this equipment—may have legal claims if they have received a diagnosis of mesothelioma, lung cancer, asbestosis, or a related disease. Workers should document their employment history, job sites, and any known contact with Foster Wheeler equipment. Consultation with an attorney experienced in asbestos litigation is advisable to evaluate available legal options, applicable statutes of limitations, and the viability of claims against Foster Wheeler and any additional responsible parties, including insulation manufacturers and contractors who may have supplied or applied asbestos-containing materials at the same work sites.
