Substantial exposure to isocyanates may occur during spray painting in autobody shops, yet information is lacking on the efficacy of the protective clothing used during spray painting. We investigated the personal and workplace factors associated with painters' dermal protection use during a large-scale exposure assessment study. Survey data indicated that 69% of painters always used gloves, with latex gloves (47%) and nitrile gloves (34%) used most frequently. Among latex glove users, 53% used thin latex (0.05-0.13 mm), 6% used medium latex (0.15-0.20 mm), and 12% used thick latex (> 0.20 mm). Among nitrile glove users, 27% used thin nitrile and 45% used medium nitrile. Sixty-three percent of painters always used coveralls, 44% preferring one particular brand. Although overspray presents an opportunity for dermal exposure to the neck and face, only 19% of painters protected these areas with personal protective equipment. Painters who always used coveralls were more likely to use gloves (odds ratio = 7.9, p = 0.061). Painters who reported ever having smoked cigarettes used gloves (p = 0.05) and coveralls (p = 0.04) more frequently. Painters who sprayed more than 34 clear coat jobs per month used coveralls most frequently (p = 0.038). Exact logistic regressions along with random sample calculations indicated that the survey results were independent of the shops. Because of the small sample size in this study, future research is warranted to corroborate these results. Studying the effectiveness of gloves and coveralls against polyurethane paints and understanding the underlying motivators and preferences for painters and business owners is needed for the development of best practices for the selection and use of dermal protection.
在汽车车身修理厂进行喷涂作业时,工人可能会大量接触异氰酸酯,但目前有关喷涂作业时所使用的防护服防护效果的信息还很缺乏。我们在一项大规模暴露评估研究中调查了与喷涂工人皮肤防护使用相关的个人和工作场所因素。调查数据表明,69%的油漆工始终使用手套,其中最常使用的是乳胶手套(47%)和丁腈手套(34%)。在乳胶手套使用者中,53%使用的是薄乳胶手套(0.05-0.13 毫米),6%使用的是中乳胶手套(0.15-0.20 毫米),12%使用的是厚乳胶手套(>0.20 毫米)。在丁腈手套使用者中,27%使用的是薄丁腈手套,45%使用的是中丁腈手套。63%的油漆工始终使用防护服,44%的人更喜欢某一特定品牌。尽管喷涂作业时会有飞溅物,使颈部和面部有机会接触到异氰酸酯,但只有 19%的油漆工使用个人防护设备来保护这些部位。始终使用防护服的油漆工更有可能使用手套(优势比=7.9,p=0.061)。报告曾吸烟的油漆工更频繁地使用手套(p=0.05)和防护服(p=0.04)。每月喷涂超过 34 个清漆作业的油漆工最常使用防护服(p=0.038)。通过精确的逻辑回归和随机样本计算,表明调查结果与车间无关。由于本研究的样本量较小,需要进一步研究以证实这些结果。研究手套和防护服对聚氨酯涂料的有效性,并了解油漆工和企业主的潜在动机和偏好,对于制定选择和使用皮肤防护的最佳实践是必要的。
