R. J. Sexton to S. C. Giambruno Transmitting Industrial Hygiene Survey of Insulation Block Dust (Thermobestos, Kaylo, Carey-Temp) at Construction Insulation Shop, with R. E. Peele Follow-up Memo (1963)

A 23 October 1963 internal memo from the Plant Medical Director transmits Industrial Hygiene Survey Report 63-IH-3-G-1 on dust from band-sawing Thermobestos, Kaylo and Carey-Temp insulation blocks in the Construction Insulation Shop. The report gives dust counts, free silica results and ventilation measurements, and concludes that Thermobestos and Carey-Temp could not be safely fabricated with existing equipment while Kaylo could. A 29 November 1963 memo from the industrial hygienist to Sexton reports a visual-only check of Carey-Temp pipe covering and says no health hazard was expected.
