Abstract

BACKGROUND: Construction workers in Hong Kong face high health risks of heat stress, solar ultraviolet radiation, and hazardous substances. A suitable work wear can lower exposure to these hazards, but the actual dressing behavior of construction workers remains unknown. OBJECTIVE: This study examines the current dressing patterns of construction workers and evaluates their limitations. METHODS: The dressing patterns of construction workers were investigated through unconcealed videotaped observation and questionnaire survey to enhance the reliability and validity of this research. RESULTS: Results indicate that construction workers were willing to wear short-sleeved shirts for a cooler feeling, although such dressing patterns may not protect them against solar ultraviolet radiation or hazardous substances. Their preferred darkcolored long pants can decrease the direct exposure to solar ultraviolet radiation and hazardous substances, but they absorb a large amount of radiation heat that increases the hazards of heat stress to the wearers. CONCLUSIONS: Thermal-related attributes were the most significant concerns of construction workers, which serve as key elements for designing appropriate work clothes for construction workers.
湿热天气下建筑工人的着装行为
背景:香港建筑工人在热应激、太阳紫外线辐射和有害物质方面面临着很高的健康风险。合适的工作服可以降低这些危害的暴露,但建筑工人的实际着装行为仍然未知。目的:本研究考察当前建筑工人的着装模式,并评估其局限性。方法:采用公开录像观察和问卷调查的方法,对建筑工人的着装方式进行调查,以提高研究的信度和效度。结果:结果表明,建筑工人愿意穿短袖衬衫以获得凉爽的感觉,尽管这种穿着方式可能无法保护他们免受太阳紫外线辐射或有害物质的伤害。他们喜欢的深色长裤可以减少太阳紫外线辐射和有害物质的直接暴露,但它们吸收了大量的辐射热,增加了穿着者热应激的危险。结论:热属性是建筑工人最关心的问题,是设计适合建筑工人工作服的关键因素。
