title: Solvent vapor exposures in booth spray painting and spray glueing, and associated operations.
abstract: Time-weighted average exposures for all solvents present at detectable levels were obtained for eighty-nine solvent-using workers and thirty-six control-group (unexposed) workers in seven plants of three companies applying paints and glues, primarily by spraying. Over twenty solvents were quantified if detected. Concentrations of specific solvents and cumulative fractions of TLVs were measured for various job types. All spray painting and most spray glueing was conducted in operating spray booths. Only low to moderate exposures were observed, with one TWA exceeding the cumulative TLV and three additional TWAs exceeding 50 percent of the cumulative TLV. It may be concluded that solvent TWA exposures in spraying of paints and glues are often well-controlled by common spray booths, and further, that other solvent-use operations including light-duty solvent wiping and manual paint mixing do not frequently produce high exposures (relative to TLV levels) in the presence of ordinary general room ventilation.
