Did you work with Babcock and Wilcox Once-Through Steam Generator (OTSG)? According to publicly filed asbestos litigation records, it allegedly contained asbestos. Here is what it was, who was exposed, and who is responsible. Babcock and Wilcox Once-Through Steam Generator (OTSG), sold from the 1960s until the 1980s. Allegedly asbestos-containing tube-support lagging, manway gaskets, and external insulation on Babcock and Wilcox once-through steam generators, based on publicly filed asbestos litigation records. Allegedly asbestos-fabric tube-support lagging, asbestos-fiber manway gaskets, and asbestos-containing external insulation, per publicly filed asbestos litigation records. Workers allegedly exposed around this product included nuclear plant boilermakers, nuclear plant pipefitters (steamfitters), nuclear plant mechanics, and nuclear plant refueling outage contractors. Asbestos claims are brought against the companies that made the products. If you worked with or around Babcock and Wilcox Once-Through Steam Generator (OTSG) and were later diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, you may have a legal claim against the manufacturer. This is educational information from an independent publisher — not a law firm — and is not legal advice.
Product Description
The Babcock & Wilcox Once-Through Steam Generator (OTSG) transferred heat from the primary coolant to the secondary side, producing superheated steam in B&W PWR designs. According to publicly filed asbestos litigation records, tube-support pads, internal lagging, primary and secondary manway gaskets, and the external insulation jacket allegedly used asbestos-fabric and asbestos-fiber materials rated for high temperature service. During eddy-current inspection outages, tube plugging, and manway openings, workers allegedly cut, ripped, and reinstalled asbestos-containing gaskets and lagging pieces, releasing respirable fibers into the steam generator bay.
Workers Exposed
Nuclear plant boilermakers allegedly performed OTSG manway openings, tube plugging, and lagging repair. Pipefitters/steamfitters allegedly worked on the primary and secondary piping tie-ins. Nuclear plant mechanics and refueling outage contractors allegedly staged the inspection scaffolding and supported disassembly and reassembly.
