Asbestos Boilers & Refractory: Exposure & Trust Fund Compensation
Industrial and marine boilers were lined with asbestos refractory bricks, surrounded by asbestos pipe insulation, and sealed with asbestos gaskets. Boiler workers — Navy boiler techs, civilian boilermakers, refractory bricklayers — have among the highest mesothelioma rates of any occupation.

What is asbestos boilers & refractory?
Industrial boilers — used for steam generation in power plants, refineries, factories, and aboard Navy ships — required extensive asbestos installations to handle the extreme operating temperatures. The asbestos package included: refractory bricks lining the firebox interior, asbestos pipe insulation surrounding the boiler shell and steam piping, asbestos gaskets and packing sealing every joint, and asbestos cloth/blanket products for high-temperature surfaces.
Major boiler manufacturers — Babcock & Wilcox, Combustion Engineering, Foster Wheeler, Cleaver-Brooks, Riley Stoker — themselves did not always manufacture asbestos products as the boiler structure, but they specified asbestos materials for installation, supplied asbestos-containing components, and oversaw construction crews that installed asbestos extensively. Refractory manufacturers (Harbison-Walker, A.P. Green, Quigley, North American Refractories) supplied the asbestos-containing bricks that lined boiler interiors.
Manufacturers and bankruptcy trusts that cover this product
The following asbestos manufacturers produced boilers & refractory products during the asbestos era and now have bankruptcy trusts that compensate exposed claimants:
Exposure mechanism
Boiler exposure occurred through multiple pathways:
- Refractory installation and replacement — chipping out old refractory bricks generated massive asbestos dust during boiler overhauls; cutting new bricks to fit added more dust
- Boiler tube replacement — removing and reinstalling boiler tubes required removal and replacement of surrounding asbestos insulation
- Pipe insulation work — steam piping connected to boilers required cutting and fitting asbestos insulation
- Gasket and packing replacement — boiler door gaskets, manhole gaskets, and valve packing replaced routinely
- Annual overhauls — boiler shutdowns for major maintenance involved tearing out and replacing large amounts of asbestos installations
Common occupations exposed to boilers & refractory
- Boilermakers (industrial)
- Navy Boiler Technicians (BTs)
- Refractory bricklayers
- Steel mill workers
- Power plant workers
- Refinery workers
Frequently asked questions
I was a Navy Boiler Technician (BT) for 12 years. What trusts apply?
Navy BTs are among the highest-exposure rates in the entire U.S. military. Typical BT trust filing: Babcock & Wilcox + Combustion Engineering (boiler manufacturers), Owens Corning/Fibreboard + Pittsburgh Corning + Eagle-Picher (pipe insulation), Garlock (gaskets), Manville (broad coverage), plus refractory trusts. 12-15 trusts typical for full-career BTs.
Were Babcock & Wilcox boilers themselves asbestos?
The boiler structure (steel pressure vessel) itself was not asbestos. However, B&W specified extensive asbestos installations for boiler operation: refractory bricks for firebox lining, gaskets for door seals, packing for manholes, and insulation for the boiler exterior and connecting steam piping. The B&W Trust covers exposure related to all these specified asbestos installations.
What's the difference between B&W and Combustion Engineering trusts?
Both manufactured industrial and marine boilers using similar designs and similar asbestos installation specifications. B&W boilers dominated some ship classes and power plant generations; CE boilers dominated others. Many facilities had boilers from both manufacturers across different eras. Multi-trust filing across both is standard for boilermakers and boiler-room workers.
I worked at a coal-fired power plant in the 1970s. Does this apply?
Yes — coal-fired power plant workers (operators, mechanics, insulators) typically have strong claim profiles. File with B&W or CE (whichever made your facility's boilers — often both at large utilities), plus refractory trusts, plus pipe insulation manufacturers. Power plant work environments were particularly asbestos-saturated.
What about industrial boiler operators (not boilermakers — just operators)?
Boiler operators (the people running boilers, not building them) had moderate-to-high exposure depending on plant configuration and proximity to boiler maintenance work. Operators present during overhauls and major maintenance had significant exposure. File with the relevant boiler manufacturer trusts plus pipe insulation trusts.
