目的了解海防某部各坑道的卫生学状况 ,为制定坑道卫生综合保障措施提供科学依据。方法按照屯兵坑道环境卫生学的要求 ,对海防某部多条沿海坑道未屯兵时坑道内的通风量、温度、湿度、CO2 浓度及空气污染物等各项环境卫生学指标进行了检测和分析。结果在所检测的 3个单位共 18条坑道的环境卫生学指标中 ,大部分坑道的风速均高于标准要求的最高限值 ;A单位坑道内的空气细菌总数平均值超过平时限值 ;B单位各条坑道内相对湿度普遍较大 ,均值超过 90 % ;各坑道内照度均几乎为 0 ,没有达到标准要求 ;其余卫生学指标多在正常范围内。结论部队进驻沿海坑道时应解决坑道内照明问题 ,并注意解决B单位各坑道中的防潮问题。
Objective To understand the hygiene status of each tunnel in Haiphong and provide a scientific basis for formulating the comprehensive safeguard measures for tunnel health. Methods According to the requirements of environmental hygiene of Tuen Mun tunnel, various environmental hygienic indexes such as ventilation, temperature, humidity, CO2 concentration and air pollutants were measured and analyzed in the tunnels when a number of coastal sections were not stationed. Results In the environmental hygiene indicators of 18 tunnels in 3 units tested, the wind speed of most of the tunnels was higher than the maximum required by the standard; the average number of airborne bacteria in tunnel A per unit exceeded the normal time limit; B The relative humidity in each tunnel was generally larger, with an average value exceeding 90%. The illumination in each tunnel was almost zero, which did not meet the standard requirements. The remaining indicators of hygiene were mostly within the normal range. Conclusion When the troops stationed in the coastal tunnels, they should solve the lighting problems in the tunnels and pay attention to solving the moisture-proofing problem in each tunnel of unit B.
