SILICA

Engineering Controls for Silica in Construction

jackhammer, cut-off saw, grinder, and tuckpointing workers

Construction workers may be exposed to hazardous dust containing silica during construction tasks, including tuckpointing brick, grinding concrete, breaking concrete pavement with a jackhammer, and cutting block and brick. 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.
