Work practices for controlling occupational exposure to air contaminants in rubber compounding and mixing areas of tire manufacturing facilities (SIC-3011) are reviewed. The adverse health effects of exposure to dusts containing rubber chemicals, which include an increased incidence of cancer of the stomach and intestines and reduced respiratory capacity, are described. Examples of industrial situations demonstrating the three routes of exposure, inhalation, ingestion, and absorption through the skin, are presented. Several work practices, including prompt clean up of spills by vacuuming or wet cleaning; careful handling of powdered chemicals; working under or close to a ventilation hood; and keeping the access doors on ventilation systems closed, are recommended. Specific work practices for rubber workers involved in handling chemicals in containers or in weighing chemicals are discussed. Additional precautions to be taken when workers handle powdered chemicals at mixers or loading stations are outlined. The authors conclude that adherence to good work practices reduces worker exposure to respirable rubber chemical dust in tire manufacturing facilities.
