B. L. Ingalls to R. J. Kronkhyte and J. L. Myers on NIOSH Air Monitoring Survey Results at the King City Bagging Rooms (1983)

Internal memo from B. L. Ingalls reporting fiber-count results from Union Carbide's own sampling during a January 1983 NIOSH air monitoring survey of the King City bagging rooms, with ceiling and TWA values for the main circuit and RG-244 bagging operators. It reports that NIOSH's preliminary counts were lower than Union Carbide's, attributes the difference to counting-lab procedure with Coalinga fiber, and recommends evaluating continuous air monitoring equipment. The exhibit attaches data tables, the February 3, 1983 trip report, and sampling data sheets.
