W. Limbaugh Laboratory Supervisor CEMENT-ASBESTOS PRODUCTS COMPANY Box 119 Ragland, Alabama 35131 Dear Sir: Attached are the results of fiber counts on filters received from you October 23, 1974. All concentrations have been converted to an eight-hour time-weighted average. All samples are below the level of 5 fibers (>5 micro meters) per cubic centimeter of air, which is the permissible exposure to airborne concentrations of asbestos set by OSHA. However, it should be noted that samples 1 and 2 exceed, and C-3 is close to the ceiling concentration of .10 fibers set by OSHA. " ................
