目的了解人员进驻坑道的环境卫生质量及危害因素。方法选择某指挥坑道内人员生活区,现场监测人员进驻前后密闭坑道内微小气候、氧含量、化学因素污染、物理因素污染和细菌总数的变化。结果人员进驻前后,密闭坑道内气压、风速、氧含量、CO、SO_2、H_2S、NO_2、NH_3和细菌总数等指标均符合《二炮阵地人员生存生活条件要求》,人员进驻后坑道内空气中总悬浮颗粒物(TSP)浓度明显升高,最高值为0.35 mg/m~3,平均值为0.26 mg/m~3,噪声最高值为80.6 dB,TSP和噪声均超过标准限值要求。结论人员在坑道内工作和生活时,影响坑道环境卫生质量的主要危害因素是TSP和噪声。
Objective To understand the quality of environmental sanitation and the harmful factors of personnel entering the tunnel. Methods Select the micro-climate, oxygen content, chemical pollution, physical pollution and total bacteria change in the personnel living area of a command tunnel, the micro-climate in the closed tunnel before and after the on-site monitoring personnel stationed. Results The air pressure, wind speed, oxygen content, CO, SO_2, H_2S, NO_2, NH_3 and the total number of bacteria in the confined tunnel were all accordant with the requirements of “living and living conditions of personnel in the Second Artillery Corps” before and after stationed in the tunnel. The highest concentration of suspended particulate matter (TSP) was 0.35 mg / m ~ 3, the average was 0.26 mg / m ~ 3, the maximum noise was 80.6 dB, and the TSP and noise exceeded the standard limits. Conclusion The main hazards that affect the quality of environmental health in tunnels are TSP and noise when working and living in tunnels.
