Exposure to asbestos (1332214) fibers and free silica (7631869) during the use of baby talcum powders (SIC-2844) was investigated. Bulk and airborne samples of nine commercial powders were examined using standard fiber count methods. Seven powders were fibrous. These were subjected to a simulated exposure test in which a doll was diapered while air was collected 10 inches from its breathing zone and that of the diapering individual. Dusting was continued for 5 or 15 seconds. A 3 minute sampling procedure was used to obtain total time average airborne concentration measurements. Fourteen dusting tests were conducted. Fifteen second dustings resulted in fibrous exposure with all tested powders, while 5 second dustings did not produce fibrous exposure with three powders. Based on an estimated 10 to 15 diaper changes per day, a cumulative exposure of 30 to 45 minutes per day was estimated. Exposure to fibers was greatest during the first 20 seconds of use and diminished rapidly. Fiber concentrations ranged between 0 to 18 fibers greater than 5 microns in length per milliliter during this time. Free silica ranged from 0.05 to 2.03 percent by weight.
