Steam Turbines with Asbestos Insulation — General Electric

Product Description

General Electric (GE) was among the most prominent manufacturers of industrial steam turbines in the United States throughout much of the twentieth century. These turbines were large, complex rotating machines designed to convert high-pressure steam energy into mechanical power, which was then used to drive electrical generators, pumps, compressors, and other industrial equipment. GE steam turbines were installed across a broad spectrum of heavy industry, including electric power generation plants, petroleum refineries, chemical processing facilities, paper mills, steel plants, and naval vessels.

Steam turbines operate under conditions of extreme heat and pressure, making thermal insulation an engineering necessity. For decades, asbestos-based insulation materials were the industry standard for managing the intense temperatures generated during turbine operation. Asbestos was valued for its exceptional heat resistance, durability, and relatively low cost, properties that made it a practical choice for insulating turbine casings, steam lines, valve bodies, and associated piping systems. GE turbines were manufactured and installed during an era when asbestos insulation was routinely applied during original fabrication, and also added or replaced during maintenance and repair cycles at industrial sites across the country.

These machines had operational lifespans measured in decades, meaning that turbines manufactured and installed during the mid-twentieth century remained in active service—and continued to require maintenance involving asbestos-containing insulation—well into the 1980s and beyond. The long service life of GE steam turbines extended worker exposure across multiple generations of industrial employees.


Asbestos Content

The asbestos content associated with GE steam turbines was not limited to a single component or material type. Litigation records document that asbestos-containing materials were present in multiple aspects of turbine construction and maintenance. These materials included thermal block insulation applied to turbine casings and housings, asbestos-containing blankets and cloth used to wrap steam lines and valve assemblies, asbestos rope packing used in joints and seals, and asbestos gaskets used at flanges and connection points throughout the steam system.

Plaintiffs alleged that GE specified, supplied, or otherwise incorporated asbestos-containing insulation products into its steam turbine systems as part of standard manufacturing and engineering practice. Litigation records further document that asbestos insulation was regularly disturbed during routine maintenance, repair, and overhaul operations, releasing fibers into the breathing zones of workers performing that work. In many cases, insulation contractors, pipefitters, and general industrial workers applied or removed asbestos materials that were integrated into GE turbine installations as part of standard operating procedure.

The presence of asbestos in these systems was not incidental. Engineering and installation specifications called for thermal insulation capable of withstanding the operating temperatures of industrial steam systems, and asbestos-based products were the predominant materials used to meet those specifications during the decades in question.


How Workers Were Exposed

Industrial workers across a wide range of job classifications encountered asbestos-containing insulation during work involving GE steam turbines. Exposure pathways were varied and often prolonged, reflecting the scale and complexity of industrial turbine installations.

Installation and construction: Workers involved in the initial installation of steam turbines applied asbestos block insulation, wrapped steam lines with asbestos cloth or tape, and fitted asbestos rope packing into valve and joint assemblies. These tasks involved cutting, shaping, and fitting insulation materials, activities that litigation records document as generating substantial airborne asbestos fiber concentrations.

Maintenance and inspection: Steam turbines required ongoing maintenance throughout their operational lives. Routine inspections, seal replacements, and mechanical adjustments often required removing and replacing asbestos insulation to access internal components. Workers who performed or assisted with these tasks were exposed to asbestos fibers released when insulation was disturbed, cut, or broken apart.

Overhaul and repair operations: Major turbine overhauls involved stripping large quantities of existing insulation from casings, steam lines, and valve assemblies before mechanical work could begin. Plaintiffs alleged that this stripping process released heavy concentrations of asbestos dust, and that workers performing or working in proximity to overhaul operations experienced significant cumulative exposure over the course of their careers.

Bystander and ambient exposure: In many industrial environments, steam turbines were not isolated from general work areas. Mechanics, electricians, pipefitters, and other tradespeople working in the vicinity of turbine maintenance operations were potentially exposed to airborne asbestos fibers even when not directly engaged in insulation work. Litigation records document claims from workers who described general ambient contamination in facilities where turbine maintenance was performed without adequate dust control.

The diseases associated with occupational asbestos exposure—including mesothelioma, asbestosis, and lung cancer—typically develop after a latency period of ten to fifty years. This extended latency means that workers exposed to asbestos during turbine work performed in the 1950s, 1960s, and 1970s continued to receive diagnoses into the first decades of the twenty-first century.


GE steam turbines with asbestos insulation have been the subject of substantial civil litigation in courts across the United States. Because GE remains a solvent, operating company and has not established an asbestos bankruptcy trust fund, claims related to GE steam turbines are pursued through direct litigation against the company rather than through an asbestos trust fund process.

Litigation history: Litigation records document that GE has been named as a defendant in a significant volume of asbestos personal injury and wrongful death cases. Plaintiffs alleged that GE knew or should have known of the hazards associated with asbestos insulation used in connection with its turbine products, and that the company failed to provide adequate warnings to workers who would foreseeably encounter asbestos-containing materials during installation, maintenance, and repair operations.

Claims basis: Plaintiffs in GE steam turbine litigation have alleged product liability, negligence, and failure to warn as theories of recovery. Litigation records document claims brought by workers diagnosed with mesothelioma, asbestosis, and asbestos-related lung cancer who alleged occupational exposure to asbestos in connection with GE turbine systems at power plants, industrial facilities, and other worksites.

Additional defendants: Many cases involving GE steam turbines also name insulation manufacturers, contractors, and suppliers whose products were used in conjunction with GE equipment. Some of those entities have since established asbestos bankruptcy trusts, providing additional avenues of recovery for eligible claimants. An experienced asbestos attorney can evaluate all potential defendants and trust fund claims relevant to a specific exposure history.

Seeking legal assistance: Workers and family members seeking to pursue claims related to GE steam turbine asbestos exposure should consult with an attorney experienced in asbestos litigation. Documentation supporting a claim typically includes employment records, facility records, medical records confirming a qualifying diagnosis, and evidence establishing the presence of GE steam turbines at the relevant worksite. Given applicable statutes of limitations, individuals with a recent diagnosis should seek legal consultation promptly.
