气焊工安全作业技术 | 2011-10-11 9:25:00

1、气焊工在进行焊、割作业时，操作类似电焊工之处，可参照电焊工的安全操作要求。
2、氧气瓶应配齐防震胶圈和瓶嘴帽，搬运时防止撞击和剧烈震动，防止摔破瓶口引起爆炸。
3、氧气瓶口、氧气表严禁沾染油脂。在氧气瓶上装卸氧气表应使用扳手，不准用其它工具敲击。瓶内氧气不宜全部用完，应留有0.3-0.5兆帕压力。
4、氧气瓶、乙炔发生器禁止接触明火，并应加遮护，防止在烈日下曝晒和受高温热源辐射。冬季施工发生冻结应用不含油脂的蒸汽或热水暖化，不准用火烤。
5、氧气瓶与乙炔发生器间距不得小于5米，二者距明火不应小于10。氧气胶管为红色，乙炔胶管为黑色或绿色，不得混用。乙炔胶管内积水，宜用压缩空气或氧气吹除后用乙炔气置换，方可使用。
6、乙炔发生器必须设有防止回火的安全装置。浮桶式乙炔发生器的浮桶应装有厚度为1-1.5毫米、直径占浮桶直径60-70％的橡胶薄膜。浮桶与定桶应用铁链相连。使用中水温不应超过60℃，超过时应停止作业，用冷水喷淋或加冷水降温。使用中不得以在浮桶上压重物的方式来提高压力。
7、乙炔发生器更换电石后，应将刚发生的乙炔气放空，防止乙炔气中混有空气，点火时引起爆炸。
8、点火时，焊炬(割炬)口不准对人。正在燃烧的焊(割)炬不得放在工件或地面上。焊、割嘴堵塞时，不许同时开启氧气及乙炔阀门，防止氧气倒流入乙炔发生器或回火防止器中。
9、乙炔管破裂着火时，应先将焊、割炬火焰熄火，然后停止供气。在氧气胶管着火时，应迅速关闭氧气阀门，停止供气。禁止折弯氧气管来灭火。
10、由于焊、割嘴过热堵塞，而发生回火或多次鸣爆时，必须迅速关闭氧气阀再关乙炔阀，然后将焊、割炬冷却，再排除故障。
11、高空作业时，氧气瓶、乙炔发生器(或乙炔瓶)应放在工作处下方上风头5米以外。禁止将氧气瓶、乙炔发生器放在高压线及主要电力线下面施工。高空切割下的料头应采用可靠方法运回地面，不准随意乱掷。
12、工作完毕应将氧气瓶气阀关好，拧上瓶嘴帽。乙炔浮桶提出时，头部应避开浮桶上升方向，拔出后要卧放，禁止扣放在地上。
