The effectiveness of a high velocity, low volume sander hood used at a facility manufacturing reinforced plastics was evaluated using personal sampling techniques with a light scattering monitor connected to a data logger. Real time instrumentation was used to obtain a time history of exposure during a short, 20 minute, sampling period. Exposure to sanding dust was measured for two workers, one using a sander with a hood, the other using a sander with no hood. Both were working on the sanding of a truck hood and fender assembly. Video recording of the operation was also taken so that worker activity variables could be logged onto the spreadsheet of the sampling results. Activities that changed worker exposures could then be identified by reviewing the exposure levels and the work cycles. While this method was not meant to replace the traditional methods of sampling and data collection, its simultaneous use may provide a good complement to traditional methods. The minimum equipment required would be a real time instrument with an analog output, a video camera and recorder capable of displaying time of day in seconds, a data logger with input adaptable to the instrument output, an IBM compatible computer equipped with two disc drives, and both data logging and spreadsheet software.
