Hot liquid hazards existing in work environments are shown to be a considerable risk for industrial workers. In this study, the predicted protection from fabric was assessed by a modified hot liquid splash tester. In these tests, conditions with and without an air spacer were applied. The protective performance of a garment exposed to hot water spray was investigated by a spray manikin evaluation system. Three-dimensional body scanning technique was used to characterize the air gap size between the protective clothing and the manikin skin. The relationship between bench scale test and manikin test was discussed and the regression model was established to predict the overall percentage of skin burn while wearing protective clothing. The results demonstrated strong correlations between bench scale test and manikin test. Based on these studies, the overall performance of protective clothing against hot water spray can be estimated on the basis of the results of the bench scale hot water splashes test and the information of air gap size entrapped in clothing. The findings provide effective guides for the design and material selection while developing high performance protective clothing.
工作环境中存在的热液体危害对产业工人来说是相当大的风险。在本研究中，通过改进的热液体飞溅测试仪评估了织物的预测防护性能。在这些测试中，采用了有和没有空气间隔层的条件。通过喷雾人体模型评估系统研究了暴露于热水喷雾下服装的防护性能。利用三维人体扫描技术来表征防护服与人体模型皮肤之间的气隙尺寸。讨论了台架试验与人体模型试验之间的关系，并建立了回归模型来预测穿着防护服时皮肤烧伤的总体百分比。结果表明台架试验与人体模型试验之间存在很强的相关性。基于这些研究，可以根据台架热水飞溅试验的结果以及服装中截留的气隙尺寸信息来估计防护服对热水喷雾的整体性能。这些发现为开发高性能防护服时的设计和材料选择提供了有效的指导。
