通过对冶金、锻造、铸造、陶瓷、纺织、印染、铁路、航运等行业的16个作业环境热环境参数和工人生理反应关系的调查,对现行的高温作业分级标准不足之处提出了一些看法,并认为IS0提出的热环境下机体反应的阈限值对我国亦是适宜的。经统计学分析发现,作业环境的计算温度和工人平均体温之间有明显相关(r=0.86)。不同气温下464名工人的主观感觉调查表明,35℃时100％的工人都有热或很热的感觉。
Through the investigation on the relationship between the thermal environment parameters and the physiological reaction of workers in 16 operating environments in metallurgy, forging, casting, ceramics, textiles, printing and dyeing, railway, shipping and other industries, some opinions on the inadequacies of the current high- It is also considered that the threshold value of the body response under the thermal environment proposed by IS0 is also suitable for our country. The statistical analysis found that there was a significant correlation between the working environment and the average body temperature (r = 0.86). A subjective sensory survey of 464 workers at different temperatures showed that 100% of workers at 35 ° C felt hot or hot.
