手把电焊作业,在整个铁路系统,遍及各个站段现场单位,分局所属以机务段、车辆段工人最多。电弧焊接是借助触点局部产生的6000～10000℃高温熔化金属,使两个部件接合。由于焊条和焊接件在电弧的高温作用下,局部进行着复杂的冶金反应,因而产生的各种有害气体、粉尘、温度和电弧光等多种因素,污染生产环境,共同作用于电焊工的身体,影响电焊工的健康,其中以锰的烟雾危害最大。为贯彻毛主席的“六·二六”指示,贯彻予防为主的方针,积极防治职业危害,我们组织了对遵义机务段电焊间的劳动条件调查,现将调查情况报告如下:
Hand welding operation, throughout the railway system, throughout the station site units, branch offices to the locomotive depot, the most depot workers. Arc welding is the contact with the local generation of 6000 ~ 10000 ℃ high temperature melting metal, the two parts jointed. Due to the complicated local metallurgical reactions caused by the high temperature of the arc, the welding rod and the welding part produce many kinds of harmful gases, dust, temperature and arcing, which pollute the production environment and work together with the body of the welder , Affecting the welder’s health, of which manganese smoke most harmful. In order to implement Chairman Mao’s “June 26” directive, implement the principle of giving priority to prevention and actively prevent occupational hazards, we organized a survey on the working conditions of welding rooms in the Zunyi locomotive depot. The investigation report is as follows:
