我分局地处鄂西北,濒临汉水中段。自1970年分局成立以来,职工人数不断增加,人员来自全国各地,其中部分职工曾参加过丰沙、石太、宝略、宝成、成渝、贵昆、川黔、成昆、焦柳等线铁路的隧道施工任务,业已证明矽尘对机体的危害是进行性的。长期接触粉尘作业的工人,虽然脱离了粉尘环境,但是潜在性损害刺激仍然有继续进展到矽肺的可能性。因此,为了加强矽肺病人的诊治管理工作,我们将分散在现场几十个单位的曾接触粉尘而现在已脱离接触多年的100名工人,进行了调查。现将有关情况分析报告如下: 调查对象与方法
My branch is located in northwest Hubei Province, on the verge of the middle of Han River. Since the establishment of Branch Bureau in 1970, the number of workers has been on the increase. The staffs come from all over the country. Some of them have participated in the training courses of Bongsan, Shitai, Baoluo, Baocheng, Chengyu, Guikun, Chuanqian, Chengkun and Jiao Liu etc. Line railway tunnel construction tasks, it has been proved that the hazards of silica dust on the body is progressive. Long-term exposure to dust workers, although out of the dust environment, but the potential damage to stimulate the possibility of continued progress to silicosis. Therefore, in order to strengthen the management of patients with silicosis, we conducted a survey on about 100 workers who had been in contact with dust for dozens of units and were now out of contact with dust for many years. Now the situation analysis report is as follows: Survey object and method
