Epoxy resin systems (ERSs) are among the leading causes of occupational allergic contact dermatitis.
To identify riskful exposures and sources of skin exposure, and to quantify skin exposure to diglycidyl ether of bisphenol A (DGEBA) epoxy monomer, in construction coating work.
Skin exposure to epoxy chemicals was studied in 5 coating companies through (a) interviews and visual observation, (b) quantifying DGEBA on 12 workers' skin by tape-stripping, (c) measuring DGEBA on 23 surfaces by wipe-sampling, and (d) quantifying DGEBA in new sewage pipe. Acetone extracts of the tapes, wipes and sawdust from a newly hardened sewage pipe were analysed by gas chromatography/mass spectrometry.
Identified riskful exposures were, for example, mixing ERSs, handling coating pots, and working above shoulder level. Epoxy stains on, for example, tools, equipment and clothing were seen in all workplaces. Protective gloves were of varying quality, and were not always suitable for chemicals. The amount of DGEBA on the workers' skin varied considerably. All screened tool handles were contaminated. Two-day-old epoxy sewage pipe contained 3.2% DGEBA.
Construction coating entails skin contact with ERSs directly and via contaminated surfaces, personal protective equipment, and recently hardened epoxy materials. Observation is a useful method for assessing skin exposure in coating work.
环氧树脂系统（ERSs）是职业性过敏性接触性皮炎的主要原因之一。
确定有风险的暴露和皮肤暴露源，并量化建筑涂料工作中双酚 A 二缩水甘油醚（DGEBA）环氧树脂单体的皮肤暴露。
通过（a）访谈和视觉观察，（b）通过胶带剥离定量 12 名工人皮肤的 DGEBA，（c）通过擦拭采样测量 23 个表面的 DGEBA，以及（d）定量新污水管中的 DGEBA，对 5 家涂料公司的环氧树脂化学物质的皮肤暴露进行了研究。用气相色谱/质谱法分析胶带、擦拭物和新硬化污水管的锯末中的丙酮提取物。
确定的有风险的暴露包括混合 ERSs、处理涂料罐以及在肩部以上水平工作等。在所有工作场所都可以看到例如工具、设备和衣物上的环氧树脂污渍。防护手套的质量参差不齐，并不总是适合化学品。工人皮肤的 DGEBA 含量差异很大。所有筛查过的工具手柄都受到了污染。两天前的环氧树脂污水管含有 3.2%的 DGEBA。
建筑涂料工作会直接通过受污染的表面、个人防护设备以及最近硬化的环氧树脂材料接触到 ERSs，导致皮肤接触。观察是评估涂料工作中皮肤暴露的一种有用方法。
