• Description:
  This report describes the exposures and controls that were evaluated during the interior demolition of a building. The tasks evaluated were the use of a track hoe to pull down plaster ceilings, the use of a skid-steer loader to handle the debris, and the use of garden hoses by laborers to suppress dust during those tasks and at the bottom of a debris dump chute inside the building. The control used during these tasks was the use of water to suppress dust. An evaluation of exposures during these tasks found that on the day sampling was conducted, three of five employees sampled exceeded the OSHA PEL for respirable dust. Two of five exceeded the NIOSH REL for respirable crystalline silica. Eight hour time weighted average exposures to respirable dust ranged from 1.7 to 6.1mg/m3. Eight hour time weighted average exposures to respirable quartz ranged from 0.037mg/m3 (based on two quartz samples between the limit of detection and the limit of quantitation) to 0.087mg/m3. These results probably reflect a reduction in exposure due to the use of water to suppress dust.
