R. J. Sexton to G. C. Gimbruno on the Johns Manville Thermobestos Insulation Block Dust Survey, with Peele Memo and Reports (1962)

A cover memo from the Institute Plant medical director, with enclosures, about dust produced when Johns Manville "Thermobestos" insulation blocks were cut with band saws in the plant's Construction Insulation Shop. Sexton wrote that he favored continued surveys of new-formula blocks but not accepting Johns Manville's invitation to visit Manville, N.J. The enclosures are a 3 December 1962 memo from industrial hygienist R. E. Peele, a 20 July 1962 cover memo, and Peele's industrial hygiene report 62-IH-2-G-1 with its dust data sheet. The report found dust concentrations above the 20 mppcf limit.
