"The purpose of this work assignment was to develop and validate predictive models used to determine the inhalation exposure levels of workers involved in the drumming of liquids ad the bagging or drumming of solids. The study consisted of four tasks. An industry survey was conducted to characterize industrial drumming and bagging operations and to select chemicals and facilities for study. An initial laboratory pilot study was performed to test emission models, dispersion theories, sampling strategies, and analytical methods. A plant-scale occupational exposure study was directed to the collection of specific data on worker breathing zone concentrations resulting from actual bag and drum filling operations. Finally, a second laboratory pilot study was performed using a drum filling station to develop a predictive model of inhalation exposure, which was tested against data from the plant-scale occupational exposure study."--Summary.
