Engineering Controls for Silica in Construction
Construction tasks that cut, break, grind, abrade, or drill concrete, mortar, stone, asphalt, and brick have been associated with overexposure to respirable crystalline silica dust. The National Institute for Occupational Safety and Health (NIOSH) found that exposure could be reduced through the use of engineering controls, including the use of local exhaust ventilation to capture dust at its source and the use of water sprays to suppress dust where it is produced. These pages provide information about those controls and utilize video-exposure monitoring clips to demonstrate their effectiveness.
