为进一步发挥人防工事在经济建设和战备中的作用,我们对人防地下环境进行了全面的调查和研究,其中包括CO_2浓度平时卫生标准的研究。关于地下工事内CO_2浓度的标准问题,部队在短期内停留的CO_2浓度标准已有详细研究,但对长期居住、劳动的CO_2浓度平时卫生标准,过去没有研究过,对此问题还没有一致的看法:一种认为1‰,另一种认为可以到27‰或3‰。为对人防工事内CO_2浓度平时卫生标准提供客观的数据,进行了本研究。选择青年学生32名参加实验共四天:一天在地面教室中上课、自习、休息共8小时。CO_2平均浓度为0.47‰;另三天在人防工事(地下教室)内上课、自习、休息,每天8小时。三
In order to further exert the role of air defense workers in economic construction and combat readiness, we conducted a comprehensive investigation and study on the civil air defense underground environment, including the research on the usual hygiene standards for CO 2 concentration. Regarding the standard of CO 2 concentration in underground works, the CO 2 concentration standards that troops stay in the near future have been studied in detail. However, the usual hygiene standards for long-term residence and labor CO 2 concentrations have not been studied in the past and there is no consensus on this issue : One that 1 ‰, the other that can be 27 ‰ or 3 ‰. In order to provide objective data on the usual hygiene standards for CO 2 concentration in air defense services, this study was conducted. Choose 32 young students to participate in the experiment a total of four days: one day in the ground classroom classes, self-study, rest a total of eight hours. CO_2 average concentration of 0.47 ‰; the other three days in civil air defense work (underground classrooms) classes, study, rest, 8 hours a day. three
