H. H. Warwick and B. L. Murray, Particulate Matter in Air: Dust Breathed by Employees While Cutting and Installing Kaylo Insulation, Plant 514 (1965)

Industrial hygiene report dated September 21, 1965, requested by the Plant Medical Director, on dust breathed by insulators who cut and install "Kaylo" asbestos insulation. It reports 24 breathing-zone air samples averaging 5.2 million particles per cubic foot, compares them with a suggested threshold limit value of 20 mppcf, and recommends exhaust ventilation, respirators and further research including animal tests. Table I, photo figure captions and two handwritten survey forms follow.
