• Description:
  Researchers from the Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH) conducted an engineering control evaluation at Cedar Rapids, Iowa Quaker Oats, a producer of cereal and other grain mill products, to: evaluate their manufacturing processes regarding potential exposure to diacetyl and other food related flavorings
  
  document the effectiveness of existing exposure control techniques
  
  and identify areas where engineering controls may need to be developed or improved. A separate NIOSH team of industrial hygienists conducted an exposure assessment at this facility
  
  these results are included in a separate report. Personal sampling (from the exposure assessment study) and a ventilation assessment were conducted to evaluate potential risks during various tasks monitored during the engineering control survey. In general, measured diacetyl concentrations at the Cedar Rapids, Iowa, Quaker Oats facility were below the proposed NIOSH Recommended Exposure Limit (REL), with the exception of the Syrup room on the 5th floor. Samples collected in this room had levels of diacetyl above the proposed NIOSH time weighted average (TWA) of 5 parts per billion (ppb) and Short Term Exposure Limit (STEL) of 25 ppb. This room also had concentrations of 2,3-pentanedione above the proposed NIOSH REL for 2,3-pentanedione of 9.3 ppb. Real-time HazDust IV mean dust concentrations for all the evaluated tasks were below the respirable dust PEL of 5 mg/m3. However, because the HazDust IV is a non-specific instrument calibrated to a reference standard, the reported concentrations are relative, and there is some uncertainty regarding actual dust exposure concentrations. It may respond differently to dusts with optical properties different from Arizona Road Dust. Therefore, general and task-specific recommendations are included to control and reduce both diacetyl and dust exposures.
