• Description:
  A survey was conducted at the DeVilbiss Automotive Refinishing Products (SIC-3563), Maumee, Ohio to document and evaluate effective technologies for the control of hazardous exposure to workers engaged in automobile spray painting. The objectives of this study were to determine whether the use of the High Volume Low Pressure (HVLP) spray painting gun, would significantly affect the concentration of air contaminants in spray painting booths at autobody painting shops. The specific air contaminants being measured included titanium (7440326), refined petroleum solvents, and particulate overspray. The effect of the spray painting gun on film thickness and mass of paint used was also evaluated. Substituting the HVLP gun for the conventional gun resulted in a reduction by a factor of 2 in the particulate overspray concentration and a 30% improvement in transfer efficiency. The authors conclude that minimizing the amount of overspray through gun selection is a useful option in addition to a spray painting booth for controlling worker exposure to overspray. Conventional guns have a transfer efficiency of less than 0.4 while the HVLP spray painting guns showed a transfer efficiency of at least 0.65. The authors conclude that the use of HVLP spray guns should be encouraged.
