Effects of Train Electrification Reformation on the Labor Sanitation in Working-room for Locomotive Drivers——Evaluation on the Quality of Exiguous Climate and Environmental Air Sanitation in the Working-room for Locomotive Drivers

Objectives To understand the present situation about labor sanitation of working room for locomotive drivers after train speed raising and electrification reformation and to survey the exiguous climate and the quality of environmental air sanitation in the working-room for locomotive drivers.

Methods The survey and evaluation were conducted according to the national standards "Technical Speculation on the Sanitation and Surveillance in Passenger Train"(TB/T 1932-2009), "Measuring Method for the Illumination in Locomotive Driver's Working-room"(TB/T 2011-87) and"General Specifications of electric locomotives"(GB/T 3317-2006).

Results The qualification rate of wind-speed, PM₁₀, CO and luminance reached 100% whenever in summer or winter, and the qualification rate of CO₂ was also higher, but the qualification rate of temperature and relative humidity were unsatisfactory.There was no significant difference (P > 0.05) on the average value of temperature, relative humidity, wind-speed, CO, CO₂, PM₁₀, luminance in driver's working-rooms between electric and diesel locomotives.

Conclusions Better air quality but some unsatisfactory exiguous climate was still an outstanding problem in driver's working-room.The contradiction of comfortable feeling with unqualified temperature was because of different measuring standards.Smoking will affect air quality dramatically. The concentration of CO and CO₂ were higher in the engine-room of diesel locomotive but the influence on the air quality of driver's working-room was limited.Heatstroke, toxication caused by CO₂ and disease caused by airconditioner would be the potential threaten to some drivers.
