铁路系统接触锰作业主要为电焊工,而电焊工又几乎遍及各厂,其中尤以机务段、车辆段、焊轨厂、工务段较多,焊接种类甚为繁多,焊接内容各不相同,因而积极防治职业性锰中毒,保护电焊工人的身体健康是我们劳动卫生工作者一项重要而迫切的任务,为此我们于一九七三年组织人力对局管内15个接触锰作业单位进行了卫生学调查,对从事电焊接触锰作业工人129例进行了健康状况的检查,现将结果报告如下:
In the rail system, manganese is mainly used as a welder, and welders almost all over the factories. Especially in the locomotive depot, vehicle depot, welding track factory and public works depot, there are many kinds of welding and different welding contents. Therefore, Active prevention and control of occupational manganese poisoning and the protection of the health of the welders are an important and urgent task for our health workers. To this end, we organized 15 manpower contacts in the management of 15 operating manganese units in 1973 for hygiene School survey, engaged in welding contact manganese workers 129 cases of health checks, the results are reported as follows:
