Abstract
Control criteria are devised for oil mists generated by production machine tool operations. Procedures used during four field surveys to identify and characterize mist generating tools and work operations are discussed along with methods to evaluate the need for local exhaust ventilation and the degree of worker exposure. The effectiveness of a local exhaust ventilation system is assessed based on duct flow rate, mist generation rate, stand off distance and azimuth angle. Mist collection efficiencies of the electrostatic precipitator, dry centrifugal, fabric filter, and wet collector are tested. The authors recommend duct transport and capture velocities of 2,200 and 220 feet per minute, respectively, for control of oil mists. These velocities can be achieved using ducts with flow rates of about 425 cubic feet minute and diameters of about 6 inches.
