• Engineering Controls for Silica in Construction 

  • 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. This CDC/NIOSH website provides information about controls for jackhammers, cut-off saws, tuckpointing, and concrete grinders, and utilizes video-exposure monitoring clips to demonstrate their effectiveness.
