Who This Page Covers

Workers at U.S. specialty-laminate, vulcanized-fibre, asbestos-paper, and transformer-gasket supplier plants serving the U.S. power transformer manufacturing industry during the asbestos era — including raw-material handlers, paper-rolling and impregnation operators, press operators, laminate-cutting and trimming workers, machinists, quality-control workers, and shipping crews.

Documented Component Supplier Defendants

Supplier-Plant Exposure Pathways

  • Raw asbestos fiber and paper handling — receiving, weighing, and dispensing raw chrysotile and amosite fiber, asbestos paper rolls, and asbestos cloth
  • Paper impregnation and resin coating — saturating asbestos paper with phenolic resin in impregnation lines
  • Laminate press operation — heat-and-pressure curing of asbestos-paper / asbestos-cloth phenolic laminate stock
  • Laminate cutting, sawing, drilling, and machining — finishing operations on cured asbestos laminate sheets
  • Vulcanized fibre roll-forming — converting asbestos-paper / phenolic-resin sheets into vulcanized fibre rods, tubes, and structural shapes
  • Machined-part production — converting laminate stock into transformer spacers, washers, barriers, and structural insulators
  • Quality control — handling and testing cured laminate and machined components
  • Maintenance, electricians, and housekeeping — accumulated asbestos dust on equipment, floors, and ductwork
  • Shipping and receiving — moving finished asbestos-bearing components to transformer OEM customers

Recipient Industries

The component-supplier plants listed above allegedly shipped asbestos-bearing transformer components to:

  • Power transformer manufacturers — Westinghouse, GE, Allis-Chalmers, McGraw-Edison/Pennsylvania Transformer Division, Cooper Power Systems, Federal Pacific, Niagara Transformer
  • Motor manufacturers — Wagner Electric, GE motor plants, Reliance Electric, A.O. Smith, Allen-Bradley
  • Switchgear and breaker manufacturers — Square D, Allen-Bradley, Cutler-Hammer/Eaton, ITE
  • Aerospace manufacturers — Boeing, Beech, Cessna
  • U.S. Navy and military procurement — under MIL-M-14 specifications for asbestos-filled phenolic compounds

Workers in this trade category — if diagnosed with mesothelioma, asbestosis, lung cancer, or another asbestos-related disease — may have legal rights. Asbestos-related diseases can develop silently for 20, 30, or even 40 years after initial exposure.
