Product Description

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that The Dow Chemical Company operated brine-electrolysis chlor-alkali facilities at Freeport TX, Midland MI, Plaquemine LA, and Pittsburg CA that used asbestos-fabric cell covers, asbestos diaphragms on foraminous steel cathodes, and asbestos-packed cell-head flange gaskets on the anode assemblies. According to those publicly filed asbestos litigation records, the asbestos-woven fabric cell covers allegedly sat over the cell tops as a seal against chlorine escape and heat, the diaphragms were allegedly vacuum-deposited chrysotile-asbestos slurry on the cathode structure, and the asbestos-packed flange gaskets were allegedly used on the cell-head brine and catholyte piping.

Plaintiffs alleged that Dow Chemical brine-electrolysis cell covers and diaphragms were allegedly removed, patched, or replaced on a rolling schedule, and that the tear-out, handling, and re-deposition released airborne asbestos fiber inside Dow’s cell rooms.
