The control technology for spray painting operations is evaluated. Industrial finishing processes, equipment, and hazards associated with their use are reviewed. The application of basic control principles of substitution, isolation, ventilation, spray booths, and work practices are summarized. The use of airless atomization, heated paint, and electrostatic attraction in place of conventional, compressed air spray equipment to significantly reduce the amount of stray mist or fog is discussed. Respirators and automated paint application are discussed and industrial ventilation requirements for spray booths are described. The use of lead (7439921), chromium (7440473), and other toxic metals in paints are summarized along with the need for respiratory protection. The mean time weighted average concentrations of paint mist in continuous painting operations ranged from 0.1 to 39.2 milligrams per cubic meter (mg/m3) paint mist and the mean concentrations of paint mist in intermittent painting operations ranged from 2.0 to 320.0mg/m3 paint mist. Spray booth capabilities of controlling total paint mist and organic solvent vapors to within recommended maximums are summarized. Other safety recommendations are included.
