电焊尘肺及其预防
 电焊时,焊条芯、焊条外的焊药和被焊接物件在高温下熔化蒸发, 氧化物颗粒飘散出来,这就是电焊烟尘。固然焊条、焊药和焊接材料不同,但主要成份都为氧化铁、氧化锰、氟化物、二氧化硅等。电焊工人长期吸进这种烟尘,患电焊尘肺的机会很高。焊工尘肺是一种混合性尘肺,其发病机会与工种、工龄、作业环境有关系。假如在密闭环境下、空气不流通、作业环境透风条件差、粉尘浓度高,并且多个焊工同时工作,发病时间就较短,发病率较高。焊工发病工龄为10~20年,也有3~5年发病的。

    电焊工防尘

    保持作业环境良好的透风条件,对电焊工最为重要。如透风条件差,应安装排气扇、抽风管等设施,尽量排除烟尘;定点焊接作业点上方、操纵者鼻子以下位置,要安装抽风罩,及时抽走烟尘,以免被操纵职员吸进。假如在容器(如大型管道、 集装箱、油罐等焊件)内焊接,应配备 排风扇、抽风机或吸尘罩 等除尘装置。焊件应干净, 没有灰尘,还要保持作业 环境的地面干净、清洁。

    电焊工人一定要佩戴护目罩与防尘口罩,定期进行健康体检。
