动车组运行车内环境卫生综合评价

目的了解我国动车组运行过程中司机室和车厢环境中电磁场强以及空气质量品质状况。方法现场测试高速动车组司机室和车厢环境卫生学状况,并与既有线空调客车进行比较分析。结果高速动车组与既有线动车组司机室和车厢空气内物理与化学卫生学指标符合国家职业卫生标准。结论高速动车组司机室和车厢环境各项理化指标符合国家相关标准要求,与既有旅客空调客车比较,动车组运行时车厢及司机室内环境空气质量品质优于普通旅客列车。

Comprehensive Survey and Evaluation of Environmental Hygiene in the Running EMUs

Objective To explore the electromagnetic fields,and air quality status in driver’s cab and carriage in the runtime of Electric Multiple Units（EMUs）.Method Field test was applied to detect the hygiene condition of the working environment in driver’s cab,carriage and dining car in EMUs,And the test result was comparatively analyzed with the air conditioned trains on the existing railway.Results The physical and chemical hygiene indexes were conformed with the national occupational health standards which were in driver’s cab and carriage of the high speed train and existing motor train unit.Conclusion The physical and chemical hygiene indexes in the driver’s cab and carriage of EMUs were conformed with the national health standards and were better than the air conditioned trains on the existing railway.
