事故回放(一)

事故回放(一)

事故经过

2007510上午1120分左右,石灰车间维修班焊工杜久红在石灰车间5#电除尘西北侧料场用气割炬割垫铁时,氧气用完。换气瓶完毕后点火,氧气管发生爆燃,造成杜久红右大腿后侧烧伤。

事故原因

1、在换气操作中,由于乙炔、氧气调节阀未关严导致乙炔回入氧气管是造成事故的直接原因。

2、杜久红安全意识不强,未按照操作规程操作是造成事故的间接原因。

预防措施

1、工作前要认真检查焊割炬射吸性、气密性,保证焊割工具符合安全要求。

2、加强安全教育、强化安全意识,提高安全操作技术能力。

安全提醒:在实际操作过程中,经常出现只关低压氧气阀,不关乙炔气阀的情况。特别是氧气即将用尽换气,氧气管内压力降低,低压氧气阀关不严时,就会发生乙炔气串入氧气管的现象。当换好氧气后,高压氧气阀打开时间较短,没能吹出混入的乙炔气时,点火就会发生爆炸。所以,在换气操作中,当乙炔阀忘记关闭时,一定要记得先打开高压氧气阀,置换一段时间,并根据经验判断氧气管内全部气体置换完后,再进行点火操作。
