摘要
极端热环境是某些特殊条件下人所处的恶劣环境,对极端热环境的研究和评价涉及到劳动安全和工作的可靠性。热应力是人体所承受极端热环境的一种程度上的描述。对湿球黑球温度,Sreq指数和ISO9886标准的生理指标等五种极端热环境指标的使用方法和特点进行了分析与评价,对这些指标使用的局限性进行了讨论。认为对极端热环境的研究,应联合使用不同指标后进行综合评价,并重点考虑人体生理反应的变化,使研究工作具有更加普遍的意义和实用性。为此,提出了对极端热环境评价体系研究工作的建议和今后的工作方向。
Extreme heat environment is abominable environment, which is mainly involved with high air temperature and high humidity in some special places where people work. Heat stress is a description of extreme heat environment human body suffers. Research and evaluation to these kinds of extreme heat environments relate to labor safety and working reliability. In this study, the characteristics of Wet - Bulb Globe Temperature, Sreq, the physiologic index in ISO9886 standard and other two evaluation indices were described; the usage technique and the limitation of these indices were also analyzed and discussed. The results show that it is more practicable and important to evaluate the extreme heat environment with an integrated assessment approach considering human bodies＇ physiology response changes.
