A field study was conducted in the B.F. Goodrich Industrial Plastics Division facility (SIC-3079), Marietta, Ohio to evaluate sources of worker dust exposure at a ventilated booth used for the weigh out and transfer of powdered materials from large drums to small bags. The sources of dust exposure evaluated were: depth of scooping, clothing, worker anthropometry, work practices, biomechanics, and specific items in the job cycle. Dust exposure for workers wearing clean clothing was not significantly different from exposure for workers wearing dirty clothing. Depth of scooping from the drum significantly affected dust exposure. There appeared also to be a relationship between the size of the worker and dust exposure when scooping from the bottom of the drum. Work practices may also play a part. The authors conclude that, while the results showed abnormally high dust levels, all three workers studied wore respirable dust respirators during the experiment to protect them from these high levels. Air flow patterns at the booth suggest that the ventilation provided may even contribute to dust exposure. Changes in this ventilation procedure are suggested along with alterations in methods of scooping to reduce the hazard from dust exposure. Manual lifting of 50 pound bags of material may increase the risk of back injury, and should be controlled by administrative or engineering measures.
