Epoxy pipe relining is a method of repairing old and worn water pipes supplying households. The method, using epoxy resin systems (ERSs), involves creating a new pipe inside an existing pipe. Large amounts of epoxy are normally handled at small, temporary worksites.
To describe working conditions and contact allergies to ERSs in 8 patients with occupational contact dermatitis related to their work in the relining trade.
Eight patients with suspected work-related eczema in the relining trade were referred to our Occupational and Environmental Dermatology outpatient unit. They were examined and patch-tested between August 2010 and May 2011.
Seven patients were patch test-positive to ERSs, and 6 of 8 reacted to the epoxy resin (MW 340) in the baseline series. Five of the patients were patch test-positive to their own work products. Seven of the cases had to leave the relining trade because of skin problems.
Relining is a widely used alternative to replacing old pipes, and entails a risk of massive skin exposure to ERSs and consequently a high risk of developing allergic contact dermatitis. Further mapping of working methods and use of personal protective equipment (PPE) is crucial to reduce hazardous skin exposure.
环氧管衬里是修复为家庭供水的旧的和磨损的水管的一种方法。该方法使用环氧树脂系统 (ERS)，涉及在现有管道内部创建新管道。大量的环氧树脂通常在小型临时工作场所处理。
描述与衬里行业工作相关的 8 例职业性接触性皮炎患者的工作条件和接触过敏反应。
2010 年 8 月至 2011 年 5 月，我们将 8 例疑似与衬里行业工作有关的湿疹患者转诊至我们的职业和环境皮肤科门诊。对他们进行了检查和斑贴试验。
7 例患者对 ERS 呈斑贴试验阳性，8 例中有 6 例对基线系列中的环氧树脂（MW 340）呈阳性反应。5 例患者对自己的工作产品呈斑贴试验阳性。7 例患者因皮肤问题不得不离开衬里行业。
衬里是一种广泛使用的替代更换旧管道的方法，它会使皮肤大量暴露于 ERS，因此患过敏性接触性皮炎的风险很高。进一步绘制工作方法图并使用个人防护设备 (PPE) 对于减少危险的皮肤暴露至关重要。
