Worker exposures and chemical releases associated with a plate-and-frame filter press and a stationary tray dryer were studied in a pilot plant. The equipment was representative of those in a chemical manufacturing plant; the filter press was previously used at a chemical plant, and the dryer trays were the same size used by dye manufacturers. A randomized series of eight experiments identified the most influential variables for inhalation exposure during the tray drying unit operation which used approximately 100 kg of CaCO3. The range of conditions studied in the eight experiments provide inhalation exposure data for evaluating the impact of physical properties, the activities performed, and the influence of worker technique.
