Product Description

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Kaiser Aluminum & Chemical Corporation potline equipment — used across Kaiser reduction potrooms — allegedly incorporated asbestos-fabric cladding on the anode/pot hood assemblies that captured HF-rich potline off-gases and asbestos-block insulation packed around the busbar conductor runs feeding each cell.

According to publicly filed asbestos litigation records, the hood cladding allegedly served as high-temperature insulation and gas-sealing material for the hood/skirt interface above each pot, while the busbar block insulation allegedly separated the high-amperage DC conductors from adjacent steel structure. Both materials allegedly abraded, cracked, and released fiber during routine anode-change cycles, hood repair welding, and full pot rebuilds.

Workers Exposed

  • Aluminum smelter potroom operators and potmen removing hoods for anode changes and skimming
  • Potline electricians torquing busbar connections and pulling shorted cells offline
  • Refractory bricklayers and millwrights performing pot relines and hood-frame rebuilds
  • Anode-bake carbon-plant workers handling prebake anode assemblies and stub cleaning
  • Maintenance welders repairing hood skirts and gas-collection ductwork
