Skin may be a significant route of exposure to organic solvents during spray painting, especially as the inhalation exposures become better controlled. The published literature regarding the field efficacy of both gloves and protective clothing is limited. The aim of this study was to qualitatively and quantitatively evaluate the effectiveness of gloves and protective clothing against organic solvents in auto body spray painting. The evaluation involved placing Permea-Tec charcoal pads (Colormetric Laboratories, Inc.) on fingers and the palm under the glove of the painter's dominant hand. Pads were also placed on the painter's right chest under the protective clothing. Sampling periods ranged from three to 37 minutes, depending on the duration of a particular task. After a painting task (priming, clear coating or single stage) was completed, pads were qualitatively inspected for a gray color change on the paper strip indicating a positive sample. The same charcoal pads were analyzed quantitatively for eight solvents (acetone, MEK, MIBK, toluene, butyl acetate, ethyl acetate, m&p-xylene and o-xylene) by gas chromatography. Only two pads of the 200 collected were positive qualitatively. Of the first 24 pads analyzed quantitatively, the type and amount of solvents detected was variable with only toluene detected on all pads. Geometric mean and geometric standard deviation of total solvents on the pads were 244.5 ug (5.4), N=14, for samples taken under the gloves and 720.0 ug (2.3), N=10, for samples taken under the protective clothing. The pads are much less sensitive qualitatively than quantitatively at detecting solvents. Solvents were detectable in all 24 first samples under the gloves and protective clothing even after a few minutes of spray painting. The results will be further discussed after the remaining data are received.
