• Description:
  Worker exposure to respirable crystalline silica was monitored during a wet abrasive blasting on the exterior walls of a parking garage. The abrasive blasting was done to remove 1/8 to 1/4 inch of concrete in order to exposure the underlying aggregate. The abrasive was wet sand that contained 80 percent dry sand and 20 percent water. The geometric mean respirable quartz concentration was 0.2 mg/m3 for workers conducting abrasive blasting and 0.06 mg/m3 for helpers. When the workers were performing abrasive blasting in areas which apparently had reduced natural ventilation, dust exposures appeared to increase.
