气焊、气割作业人员安全操作规定及要求

[ 2011-12-16 21:37:00 | By: 杨远锋 ]

(1)施焊场地周围应清除易燃、易爆物品，或进行覆盖、隔离。
        (2)氧气瓶、乙炔瓶所设的位置，距火源的位置不得少于10m。
        (3)乙炔瓶要放在空气流通好的地方，严禁放在高压线下面，要立放固定使用，严禁卧放使用。
        (4)使用乙炔瓶时，必须配备专用的乙炔减压器和回火防止器。
        (5)氧气瓶和乙炔瓶装减压器时，对瓶口污物要清除干净，以免污物进入减压器内。
        (6)瓶阀开启要缓慢平稳，以防气体损坏减压器。
        在点火或工作过程中发生回火时，要立即关闭氧气阀门，随后关闭乙炔阀门。重新点燃前，要用氧气将混合管内的残余气体吹静后进行。氧气瓶应有防尘胶圈、旋紧安全帽，避免碰撞和剧烈振动，并防止暴晒。冻结时应有温水加热，不准用火烤。
        (7)点火时，焊枪口不准对人，正在燃烧的焊枪不得放在工件或地面上。
        (8)严禁在带压的容器或管道上焊割。带电设备应先切断电源。
        (9)不得手持连接胶管的焊枪爬梯、登高。
        (10)防护装置要经常检查和维修，防止漏气。同时要严禁气路沾油，以防止引起火灾危险。
        (11)氧气瓶、乙炔瓶(或乙炔发生器)在寒冷地区工作时，易被冻结。此时只能用温水解冻(水温为40℃)不准用火烤；同时也要注意不得放在日光直射或高温处，温度不要超过35℃。
        (12)点火前，检查加热器是否有抽吸力，其方法是：拔掉乙炔胶管，只留氧气胶管，同时将拧开氧气阀和乙炔阀，这时可用手指检查加热器乙炔管接口处有无抽吸力。有抽吸力时，才能接乙炔管进行点火；如果没有抽吸力，则说明喷嘴处有故障，必须对加热器进行检修，直至有抽吸力时，才能进行点火。
        (13)停止工作时，必须检查加热器的混合管内是否有窝火现象，待没有窝火时，方可收起加热器。
        (14)乙炔气使用压力不得超过0.15MPa，输气流速不超过1.5-2.0m3/h，当需用较大气量时，可将多个乙炔瓶并联起来使用。
