• Description:
  Breathing zone samples were analyzed for total dust at Mainstreet Enterprises (SIC-3273, SIC-3241, SIC-8331), Lebanon, Indiana in January to February 1984. The survey was part of a field evaluation of a disposable respirator. Twenty-two pairs of breathing zone samples were obtained. One sample of each pair was collected from inside the respirator and was used to calculate the dust concentration (Ci) inside the respirator. The other sample was collected outside the respirator and the outside dust concentration (Co) was calculated. Workplace protection factors (WPF), and the ratio of Co to Ci were calculated. Area air samples were obtained to determine the particle size distribution. In the breathing zone samples, Co ranged from 2.6 to 101.6 milligrams per cubic meter (mg/m3). Ci ranged from 0.2 to 10.7mg/m3. The OSHA standard for total dust is 15mg/m3. The WPF averaged 17.9. The NIOSH assigned WPF for this type of respirator is 5.0. The aerodynamic mass median particle diameters ranged from 6.0 to 26.2 micrometers. The author concludes that workers at the facility are overexposed to total dust. This disposable respirator is effective in reducing exposure. Recommendations include improving engineering controls (ventilation) and work practices to reduce dust exposures.
