Montello, Inc. Transmittal of Union Carbide Report on Airborne Asbestos Dust in Drilling Fluid Operations Using Wet-Refined Super Visbestos (1973)

Montello, Inc. cover letter and summary sheet attached to a February 22, 1973 Union Carbide Mining & Metals Division report by H. S. Rhodes and E. J. Kleber on airborne asbestos fiber counts measured at four drilling-mud dumping sites using wet-refined asbestos (Arcovis 953 and Super-Visbestos). The report compared fiber counts with OSHA ceiling and time-weighted-average limits and concluded the products were below those limits; the exhibit also includes a Montello form letter to drilling companies and a mailer panel.
