• Description:
  A study was made to document and evaluate effective techniques for the control of potential health hazards at General Castings, Powers Street Facility (SIC-3321), Cincinnati, Ohio. The facility was a gray and ductile iron foundry with 32 employees. Following the installation of a ventilated workstation, a statistically significant decrease was noted in the dust exposure to the operator in this foundry. Significant reductions were noted for exposure due to the use of the cup grinder, the cone grinder and the cut off wheel. The percentage of dust reduction per tool ranged from 60% to 90%. The time weighted average exposures for these workers would be expected to decrease as the use of the tools is the primary source of silica (14808607) exposure. There was no significant change while using the pneumatic chisel, as these exposures were among the lowest reported even before the system was installed. The author concludes that the effectiveness of the ventilated workstation underscores how local exhaust ventilation can effectively control worker exposures if applied properly. Installation of the system significantly reduced the operator's exposure without increasing the amount of air exhausted by the ventilation system. The author suggests that similar workstations be installed in an effort to reduce other exposures.
