• Description:
  Demolition, crushing and chipping work is common in construction and can expose workers to respirable crystalline silica (RCS) dust. This study was conducted to measure exposure to RCS and respirable dust during these tasks and to evaluate the effectiveness of selected dust suppression methods on reducing exposures. Exposure monitoring was conducted of operating engineers at demolition and crushing sites, laborers at demolition sites, crushing machine tenders at crushing sites, and chipping workers at substructure bridge repair sites. A total of 51 personal breathing zone samples and 33 area samples were collected. Exposures with and without dust suppression methods were compared when possible.
