• Description:
  An empirical-conceptual modeling approach was developed by Carlton for estimating worker exposure to air contaminants during high pressure conventional air atomization spray painting. McKernan and Gatano sought to extend this model to the case of high volume, low pressure (HVLP) spray application technology. Significant differences between the Carlton and Gatano/McKernan model were established. This research used a similar experimental methodology as Carlton and Gatano/McKernan to investigate the nature of these differences and to evaluate the sensitivity of the HVLP model to variations in test setup and sampling methodologies. A series of experiments using a mannequin, flat plate, and an HVLP spray application system were performed in a 25 ft^2 simulated cross draft spray booth. Spray gun hand orientation and lapel sampling location resulted in significant differences in measured breathing zone concentrations at similar test conditions. Minimal effects however were attributed to excessive wind tunnel blockage. [Description provided by NIOSH]
