What it shows
Xerox used a machine part (No. 57P118) made of Marinite 65. In the May 3 letter, Fenner describes a test in which a technician would "handle the piece, pick it up, put it down, rub his hands over the surface, rub his hands together" while wearing a personal air sampler. He also corrects an earlier statement: "I told you that MARINITE 65 contained 60% chrysotile asbestos. I find actually it has 55% chrysotile asbestos." He says J-M was working on a heat-treated Marinite "in which the asbestos will have been converted to forsterite, rendering the product biologically inert."
The May 29 letter reports three handling tests of 15, 15 and 30 minutes at 1.6, 1.1 and 2.2 fibers/cc, and encloses J-M's "Environmental Facts/Asbestos" booklets. The Ebert sheet lists five tests (0.7 to 1.6 fibers/cc) against a "maximum allowable" of 10 fibers/cc; its figures do not match the letter's.
