Abstract

Objectives: To develop a device to evaluate the permeation resistance of chemical-protective boots continuously in contact with liquid chemicals, and to compare the permeation time of the component material test pieces with the permeation time of the whole boot and thus evaluate its performance.

Methods: The permeation time was calculated for toluene, dichloromethane, and acetone in 4 types of boot, according to Japanese Industrial Standard (JIS) T 8117:2005.

Results: The permeation test for whole boots showed shorter permeation times than those of the component materials, according to JIS T 8117:2005. The permeation time of toluene was more than twice that of boots C and D. The permeation time of dichloromethane was more than twice that of boots A and C and more than 3 times shorter for boot A.

Conclusions: The differences between the whole-boot tests and the material tests were thought to be related to variations in thickness, type of material, difference in adhesion, and penetration from pinwheels. This method enables the determination of the permeation of chemicals and other performance characteristics of the whole boot, which cannot be determined using testing of material specimens alone. By using this device for testing, appropriate boots that are protective against specific chemicals and can prevent chemically induced damage to the feet can be more efficiently selected.

研制了一种全防护靴化学渗透试验装置。

目的：研制了一种连续接触液体化学品的全型化学防护靴的耐渗透性能评价装置，将材料试件的渗透时间与全型化学防护靴的渗透时间进行比较，评价其性能。方法：根据JIS T 8117:2005（日本工业标准），计算四种靴子中甲苯、二氯甲烷和丙酮的渗透时间。结果：根据JIS T 8117:2005，全靴渗透试验结果显示，渗透时间比材料渗透试验短。甲苯的渗透时间是C、d靴的两倍多，二氯甲烷的渗透时间是A、C靴的两倍多，A靴的三倍多。结论：全靴试验与材料试验的差异可能与厚度、材料类型、附着力差异、风车渗透等因素有关。这种方法可以测定整个靴套的透气性和其他性能，而这些是单独使用材料测试无法确定的。通过使用该设备进行测试，可以选择合适的、能够更有效地防止化学物质对脚造成伤害的特定化学防护靴。

期刊介绍： The scope of the journal is broad, covering toxicology, ergonomics, psychosocial factors and other relevant health issues of workers, with special emphasis on the current developments in occupational health. The JOH also accepts various methodologies that are relevant to investigation of occupational health risk factors and exposures, such as large-scale epidemiological studies, human studies employing biological techniques and fundamental experiments on animals, and also welcomes submissions concerning occupational health practices and related issues.
