Product Description
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Monsanto Chemical Company operated electric-arc phosphate furnaces and phosphorus derivatives plants at Soda Springs ID, Columbia TN, Sauget IL, and other sites that used asbestos-fabric outer lagging on steam-jacketed molten elemental phosphorus (P4) and phosphorus-pentoxide (P2O5) transfer lines, asbestos-block hot-side lagging on phos-furnace hoods and off-gas ducts, asbestos-refractory tap-hole packing and hearth patch material on the phos-furnaces, and asbestos-packed flange gaskets on hot process piping. According to those publicly filed asbestos litigation records, the asbestos-fabric lagging allegedly held skin temperatures down on the transfer piping to keep P4 molten and prevent solidification.
Plaintiffs alleged that Monsanto phosphate furnaces required frequent tap-hole repack and hearth patch on a rolling schedule, and that transfer-hose lagging was allegedly stripped and re-lagged during scheduled turnarounds.
