Product Description

Chemetron Corporation (Chicago, IL; historically parent of Selas Corporation and holder of industrial-furnace product lines including heat-treat and annealing furnaces) allegedly manufactured and marketed industrial furnaces to steel finishers, forge shops, and heat-treat job shops across the U.S. from the 1950s through the early 1980s. Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Chemetron industrial furnaces used chrysotile-fiber woven “tadpole” tape and asbestos rope door-frame seals around access doors, quench-tank hoods, and hearth-plate joints, and that compressed asbestos fiber (CAF) sheet gaskets were installed under burner-mount flanges on the furnace shell.

Plaintiffs further alleged that Chemetron-supplied replacement seal kits — furnished as maintenance items during quarterly preventive maintenance and full furnace re-line — continued to specify asbestos-fabric seal stock into the early 1980s.

Workers Exposed

Plaintiffs allegedly identified the following trades as exposed during Chemetron industrial-furnace service:

  • Heat-treat operators loading and unloading through door frames and re-seating asbestos rope seals as they burned down.
  • Industrial millwrights replacing door-frame tadpole tape and cutting fresh sections from spooled asbestos-cloth stock during quarterly PM.
  • Refractory bricklayers stripping asbestos-rope hearth joints during full furnace re-line.
  • Industrial insulators stripping and re-installing asbestos-fabric burner-flange gaskets during burner rebuilds.

Alleged exposure mechanisms included prying dry, brittle burned-down asbestos rope from door frames with a scraper, cutting fresh tape from bulk spools, and dumping spent seal debris into open scrap barrels.
