Abstract
The weight out operation was examined in a small dye house, Multi Color Industries, Inc. (SIC-2261), located in Brooklyn, New York. During the operation at the dye house, the weight out operator may be exposed to dye dust when scooping, transferring, weighing, or bagging the dye. A semi down draft, recirculating ventilation booth was installed at the site, and weight out operations were conducted. Site logistic problems prevented moving the dye drums into the booth, and most scooping operations were conducted outside the booth. Air samples were taken which showed that dust exposures to the worker were on the order of magnitude of ambient total particulate air pollution. The aerosol monitoring data indicted that the booth controlled dust exposure to the worker when inside the booth. When compared to data taken prior to the installation of the booth, the worker's exposure was reduced five fold. When examining the impact that the height of the drum had on dye dust exposure, an exposure reduction of about a factor of three was found for particles larger than 3 micrometers when using a shorter drum. When working with a more dust generating dye, the shorter drum reduced exposure by a factor of seven for particles larger than 3 micrometers.
