T. Frank Tobin (Stedfast Rubber) to Union Carbide on Respirators for Asbestos Resin, and J. A. Riddle's Reply (1969)

On May 2, 1969, the plant manager of Stedfast Rubber Company wrote to Union Carbide's Chemical Division. He said the company's insurer wanted to know the asbestos content of the asbestos resin it bought and whether protective respirators were required. In a May 9, 1969 reply, J. A. Riddle, Plant Manager, described Calidria Resin-Grade 144 as nearly pure chrysotile, discussed crocidolite and the unsettled chrysotile cancer question, cited Walsh-Healey standards, and described the respirator Union Carbide required.
