• Description:
  An empirical model for the estimation of worker exposure was based on dimensional analysis and predicted breathing zone concentrations of paint mist during spray painting activities. A laboratory wind tunnel was used with a mannequin, flat plate, and spray nozzle to develop the model. Using the model it was possible to successfully explain the variability in the average breathing zone concentration of the mannequin within measurement uncertainty. A significant effect on breathing zone concentrations was demonstrated by the orientation of the mannequin to the free stream. The concentration of the breathing zone was affected by a dimensionless quantity which consisted of spray nozzle pressure, mannequin height, liquid viscosity, and average free stream velocity. While the authors note that differences between the setup used in the experimental study and the conditions actually found in the workplace may limit the usefulness of their model, they suggest that their findings indicate there is good potential for empirical/conceptual models which are based on dimensional analysis to be able to usefully predict breathing zone concentrations. Such findings could result in more effective control interventions and reduced exposures to the workforce. [Description provided by NIOSH]
