• Designing Dust Hoods for Better Dust Containment 

    This two-hour webinar will review the types of hoods commonly used and the process/dust collection interface issues, particle characteristics, and environmental conditions to address in hood design.  Videos will aid the participant in visualizing how hoods work and some of the more common interferences. 

  • 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.
