Product Description

Worthington Corporation allegedly supplied reciprocating plant-air and process-air compressors — single-stage and multi-stage, single-acting and double-acting — to U.S. power stations, refineries, chemical plants, paper mills, steel mills, food-processing plants, and Navy shore facilities from the 1930s through the 1980s. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Worthington reciprocating air compressors were assembled with compressed asbestos sheet gaskets at every cylinder head, valve-plate seat, intercooler flange, aftercooler flange, and cover bolt, and that double-acting frames used braided asbestos rope packing at each piston-rod stuffing box.

Routine “valve and packing” service on Worthington reciprocating frames allegedly required the mechanic to remove the cylinder head or valve cover, scrape the compressed asbestos gasket off the mating flange with a knife and wire brush, cut a fresh gasket from asbestos sheet stock, and install it. On double-acting units the piston-rod packing was pulled and re-driven with fresh asbestos rope rings. Both operations released dry chrysotile fibers into the compressor room air.

Workers Exposed

  • Industrial mechanics performing scheduled valve-and-packing changes on Worthington reciprocating air compressors.
  • Millwrights rigging cylinders and intercoolers during major Worthington overhauls.
  • Pipefitters (UA) breaking discharge and cooling-water piping into Worthington compressor units.
  • Machinists rebuilding Worthington valves, pistons, and rod-packing cases.
  • Boiler tenders (BT) working the associated plant-air distribution in power houses and boiler rooms.

Bystanders in the compressor room were exposed to airborne fibers released by gasket scraping and packing removal.
