Key Findings from Research: Silica Dust Reduction Through Hollow Bit Drill Ventilation

• Description:
  Commercial construction workers frequently drill 1-3 cm diameter holes into concrete for structural upgrades (e.g., dowel and rod drilling) and for inserting anchor bolts for hanging pipes, conduit, or equipment. Industrial construction projects may require drilling thousands of these holes, work that can generate concentrations of respirable silica dust well in excess of the ACGIH Threshold Limit Value (TLV(R)=0.025 mg/m3). This study evaluated a new method of local exhaust ventilation (LEV) -using a drill with a hollow bit connected to a vacuum-and compared it to a standard shroud LEV system and to no local exhaust ventilation.
