Technology used to control worker exposures during spray painting and coating processes is evaluated. Coatings technology, application methods, and finishing practices are reviewed. Potential health hazards, control methods reported in the literature, and procedures to evaluate control methods are summarized. Results of field surveys conducted in the automobile refinishing (SIC-7535), wood and metal furniture finishing (SIC- 3479), appliance finishing (SIC-3479), nonautomotive transportation equipment (SIC-17), and heavy machinery industries (SIC-17) are summarized. The processes selected represent typical spray finishing operations in relation to the number of exposed workers, different control techniques, workpiece physical size, and coating systems used. Each illustrative survey includes a hazard analysis, ventilation measurements, air sampling data, and a discussion of engineering controls, work practices, and personal protective equipment used. The level of control of selected health hazards is discussed, and available control options are evaluated. General conclusions and recommendations based on the surveys are included.
