Product Description

Anchor Packing Company (Garlock affiliate) allegedly supplied compressed asbestos sheet (CAS) gasket stock to U.S. Navy shipyards, Navy tender ships, and shipboard supply chains through the mid-twentieth century. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Anchor Navy-grade compressed asbestos sheet stock was cut, fitted, and installed at shipboard steam-system, feedwater, fuel-oil, and auxiliary-system flanges throughout the fleet.

Bulk compressed asbestos sheet was supplied to Navy stock in standardized thicknesses and grades. Aboard ship and in shipyard gasket shops, workers laid the sheet stock over the flange, traced or die-cut the gasket profile, and dressed the edges. Cutting the compressed sheet with a knife, shears, or hand die released chrysotile fibers from the freshly-exposed edge of the material. During subsequent overhauls, the used gasket vitrified onto the mating flange had to be scraped free — again generating respirable fiber concentrations at the flange face.

Workers Exposed

  • Machinist’s mates (MM) cutting and installing shipboard gaskets on turbines, pumps, valves, and heat exchangers.
  • Boiler tenders (BT) cutting and installing boiler-front, manway, handhole, and steam-drum gaskets.
  • Hull technicians (HT) working on fuel-oil, potable-water, and firemain flange joints.
  • Shipyard machinists running Navy-yard and private-yard gasket shops during availabilities and construction.
  • Pipefitters (UA) making up and breaking down piping joints at every flanged interface aboard ship.

Bystanders in the gasket-cutting shop, boiler room, or engine room breathed the fibers released during cutting and scraping operations.
