Abstract The original proposal stated-'The primary hypothesis is that the lowest exposure results when the worker is to the side of the object being painted, with the spray gun in the downstream hand; rather than standing in front of the workpiece as is typically the case. The following specific aims are proposed: (1) Improve existing numerical algorithms and use commercially available (CFD) packages to generate predictions of breathing zone concentration for specific work practices described in the primary hypothesis above, and incorporating factors listed; (2) Construct a working laboratory model of a spray operation using a moveable mannequin and actual compressed air spray gun; (3) Conduct experiments using this laboratory model to calibrate numerical predictions of exposure and validate the primary hypothesis; (4) Use flow visualization to confirm numerically predicted flow patterns, and to demonstrate the effects of boundary layer separation; (5) Conduct a field validation of the model in actual spray paint booths. Personal samples will be taken to confirm the primary hypothesis, and evaluate the numerical predictions of worker exposure.'
