R. J. Sexton to S. C. Giambruno on the Insulation Block Dust Survey of Johns-Manville "Thermobestos" at the Institute Plant (1962)

A cover memo from the Institute Plant medical director forwards industrial hygienist R. E. Peele's 3 December 1962 memo and the enclosed 1962 industrial hygiene survey of dust from sawing Johns-Manville "Thermobestos" and Owens-Corning "Kaylo" insulation blocks. The memo recounts the earlier reports, a Johns-Manville visit and invitation, and pressure on the plant. The survey reports dust counts above the 20 mppcf limit for Thermobestos and recommends against fabricating the blocks with existing equipment.
