Abstract
An evaluation of control technology for spray painting operations was made by a series of field surveys of finishing operations supplemented by a review of the literature. Spray booths that meet OSHA design requirements were found to be capable of controlling total paint mist and organic solvent vapors to within recommended maximums. They are partially effective in the control of toxic metals and other dangerous materials, insofar as they contain the hazard within the booth. The working environment of the spray finisher can also be improved by the use of paint application methods that minimize the energy expended in the atomization process. Respiratory protection was found to be required in those spray finishing operations that employ significant quantities of highly toxic materials, such as lead, chromium, or reactive compounds (isocyanates and epoxy curing agents). It is also necessary for protection against paint mist and organic solvents in painting enclosed spaces or other areas where ventilation is compromised.
