Babcock & Wilcox Package Boilers with Asbestos Insulation
Product Description
Babcock & Wilcox (B&W) was one of the most prominent manufacturers of industrial steam-generating equipment in the United States, with a history in boiler manufacturing stretching back to the mid-nineteenth century. Among the company’s extensive product line, package boilers represented a significant category of prefabricated, self-contained steam and hot water generation units designed for industrial, commercial, and utility applications.
Unlike field-erected boilers assembled piece by piece at a job site, package boilers arrived at their installation locations largely pre-assembled at the factory. This configuration made them attractive for facilities that required a compact, ready-to-operate steam source — including manufacturing plants, refineries, chemical processing facilities, hospitals, institutional buildings, and marine vessels. Babcock & Wilcox produced package boilers across a broad range of capacities, from smaller commercial units to large-scale industrial configurations capable of generating substantial steam output for process or power generation needs.
Because high-temperature steam generation requires effective thermal management, insulation was a critical engineering component of these units. Throughout much of the twentieth century, Babcock & Wilcox incorporated asbestos-containing insulation materials into the construction and finishing of its package boilers. Asbestos was the insulation material of choice for decades due to its heat resistance, durability, and relatively low cost — properties that made it standard practice across the boiler and pressure vessel industry well into the 1970s and beyond.
Asbestos Content
Asbestos was integrated into Babcock & Wilcox package boilers in multiple forms and at several locations throughout each unit. The external jacket insulation applied to boiler shells and fireboxes commonly contained asbestos in block, blanket, or cement formulations. Boiler doors, access panels, and inspection ports were frequently gasketed with asbestos-containing materials to maintain seals under high heat and pressure cycling.
Internal refractory and fireside insulation — lining combustion chambers and furnace walls — relied heavily on asbestos-containing refractory cements and castable materials. Pipe connections, steam outlets, and auxiliary fittings attached to the boiler were wrapped or packed with asbestos insulating products to prevent heat loss and protect adjacent equipment. Rope gaskets, block insulation, and finishing cements applied during both factory assembly and field installation frequently carried significant asbestos content.
Asbestos was also present in materials used during maintenance and repair cycles. When insulation degraded or boiler components required service, replacement insulation materials of the same asbestos-containing composition were routinely installed. This pattern of repeated maintenance exposure extended the period during which workers could come into contact with asbestos-containing products associated with Babcock & Wilcox package boilers long after the original installation date.
How Workers Were Exposed
Workers across a range of industrial trades encountered asbestos from Babcock & Wilcox package boilers throughout the boiler’s life cycle — from initial installation through years of operation, maintenance, repair, and eventual demolition or decommissioning.
Installation workers who received, positioned, and connected package boilers at industrial and commercial sites handled pre-insulated equipment and applied additional field insulation. Cutting, fitting, and troweling asbestos insulation materials during these activities generated respirable asbestos dust.
Boilermakers and pipe fitters who connected steam lines, installed gaskets, and completed mechanical tie-ins worked directly with asbestos-containing sealing and insulation products. Tightening flanges and cutting asbestos rope packing to length were routine tasks that could release fiber.
Insulation workers (insulators) applied, repaired, and removed the block insulation and finishing cements that coated boiler exteriors. Removal and replacement of degraded insulation — whether during scheduled maintenance shutdowns or emergency repairs — involved breaking apart and handling friable asbestos-containing materials, producing some of the highest airborne fiber concentrations associated with boiler work.
Maintenance and repair personnel employed at facilities operating Babcock & Wilcox package boilers were exposed during routine service activities: replacing gaskets, repairing refractory linings, inspecting and relining fireside surfaces, and removing lagging to access mechanical components. These workers often performed their tasks in confined mechanical rooms or utility spaces where ventilation was limited, increasing the concentration of airborne fibers.
Industrial workers generally — including operators, supervisors, laborers, and facility maintenance staff who worked in proximity to operating or maintained boilers — could be exposed to asbestos fibers released during maintenance activities even without directly handling insulation materials. Bystander exposure in shared workspaces is well documented in occupational health literature and litigation records involving boiler equipment.
Because package boilers were used across such a wide variety of industries — including petrochemical, manufacturing, food processing, institutional facilities, and others — the population of potentially exposed workers is correspondingly broad.
Documented Trust Fund / Legal Options
Babcock & Wilcox faced extensive asbestos-related personal injury litigation arising from its manufacture and sale of boilers and other asbestos-containing products. As a result of this litigation and the resulting financial pressure, Babcock & Wilcox reorganized under Chapter 11 of the U.S. Bankruptcy Code, and as part of that reorganization, the Babcock & Wilcox Asbestos PI Trust was established to resolve asbestos personal injury claims.
The Babcock & Wilcox Asbestos PI Trust is a Tier 1 trust fund resource, meaning that individuals diagnosed with asbestos-related diseases who can document occupational exposure to Babcock & Wilcox products — including package boilers with asbestos insulation — may be eligible to file a claim directly with the trust without pursuing active litigation.
Eligible diseases typically recognized under asbestos personal injury trust claim procedures include:
- Mesothelioma (malignant, any site)
- Lung cancer (with documented asbestos exposure history)
- Other asbestos-related cancers (laryngeal, esophageal, colorectal, and others per trust criteria)
- Asbestosis and other nonmalignant asbestos-related conditions (including pleural disease, with appropriate medical and exposure documentation)
Claim eligibility generally requires that a claimant demonstrate a qualifying diagnosis, meet applicable exposure criteria showing occupational or other contact with Babcock & Wilcox asbestos-containing products, and satisfy any applicable exposure period requirements established by the trust’s claims resolution procedures.
Documentation that supports a claim may include employment records, union records, Social Security work history, co-worker affidavits, facility records identifying Babcock & Wilcox boilers at job sites, and medical records establishing an asbestos-related diagnosis.
Workers or family members who believe they may have been exposed to asbestos from Babcock & Wilcox package boilers should consult with an attorney experienced in asbestos trust fund claims. Trust claim procedures, payment percentages, and documentation requirements are governed by the trust’s current Trust Distribution Procedures (TDP), and an experienced attorney can assess individual eligibility and assist with the claims process.
Survivors and family members of deceased workers may also have standing to file wrongful death or survival claims through the trust, depending on applicable state law and trust eligibility criteria.
