极端热环境危害户外作业人员的身体健康，对工作场所安全构成潜在威胁。2019年夏季，在中国南方的建筑工地进行了包括热参数测量在内的现场调查。得到了健康风险与热参数之间的关系。分析了不同室外环境条件下工人的热感觉和满意率，并通过热指标对比提出了建议。对热指标的热应力类型进行了研究。结果表明：当空气温度高于34℃时，应减小工况强度；室外温度低于34℃，风速大于1.3 m/s时，工人满意率较高。用于评价户外作业人员舒适度的热指标需要根据当地气候和工作环境进行修改，避免过度暴露在高温工作环境中。
Extreme thermal environment harms the health of outdoor workers and poses a potential threat to workplace safety. A field survey, including thermal parameter measurements, was conducted at construction sites in South China during the summer of 2019. The relationship between health risk and thermal parameters was obtained. The thermal sensation and satisfaction rate of the workers at different outdoor environmental conditions were analyzed, and recommendations were made based on the comparison of thermal indices. The thermal stress categories of the thermal indices were also investigated. The results suggest that the intensity of working conditions should be reduced when the air temperature is higher than 34 °C; the satisfaction rate of workers was found to be relatively high when the outdoor temperature is lower than 34 °C and the wind speed is greater than 1.3 m/s. Thermal indicators used to evaluate the comfort level of outdoor workers need to be modified according to the local climate and working environment to avoid excessive exposure to high-temperature work environments.
