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。
