Resuspension of dust from work clothing as a source of inhalation exposure.
Am Ind Hyg Assoc J 1986 May; 47(5):255-258
The effect of wear on the amount of beryllium (7440417) resuspended from work shirts worn by employees at a beryllium refinery was assessed. The concentration of beryllium in the fabric of three relatively new shirts and three old worn shirts were determined after the shirts had been worn one full workshift by employees at a beryllium plant. One of the new shirts and one of the old shirts were laundered, the others were tested unwashed. Swatches taken from the shirts were agitated to resuspend beryllium particles inside a closed steel glove box, and air samples were collected with filter cassette monitors. Very high concentrations of beryllium were found in the work shirt fabric; excluding the washed new shirt, beryllium concentrations from the fabric ranged from 12 to 37mg/m3. Significantly more beryllium was resuspended from the old shirts than the new shirts. The fabric from the new washed shirt contained significantly less beryllium than all other shirts. The concentration of beryllium in the old washed shirt was significantly greater than the concentration in the new washed shirt and was not significantly different from the concentration in the unwashed old shirts. The authors conclude that this pilot study provides evidence that wear significantly affects the amount of beryllium containing dust resuspended from work shirts.
