Acquisition and Spreadsheet Analysis of Real Time Dust Exposure Data: A Case Study

Abstract Personal sampling with a light-scattering monitor connected to a data logger has been used to evaluate the effectiveness of a high-velocity, low-volume (HVLV) sander hood used in a plant manufacturing reinforced plastics. Exposures to sanding dust were determined for two workers, one using a sander with a hood, the other using a sander with none. Both workers were partners in a two-person team sanding a truck hood and fender assembly. Side-by-side filter sampling was conducted to calibrate the aerosol monitor. Data logger output for each worker was combined into a single spreadsheet program. Simultaneous video recording allowed worker activity variables (sanding, compressed air blowing, and other) to be coded onto the spreadsheet, which permitted calculation of the contribution of each activity to each worker's dose of dust. The computerized data acquisition system permitted identifying activities that change worker exposures through review of the work cycle while tracking worker exposures. Thoug...
