Glen W. Sutton (Bureau of Mines) to F. H. Larrison Transmitting the Asbestos Dust Health Survey Report on the Calidria Plant, with Bureau of Mines Report and Larrison Letter to California Division of Industrial Safety (1972)

A January 28, 1972 cover letter from the Bureau of Mines transmits a report on its October 4-6, 1971 asbestos dust health survey of Union Carbide's Calidria plant at King City. The report describes plant conditions, 62 airborne fiber samples counted against a proposed 5 fibers/ml limit, and engineering and respirator recommendations. A final page is an undated letter from the plant manager to a California safety official about respiratory protection for the bagging and palletizing operators.
