200×年×月×日,某石化公司净化工段变压吸附岗位,计控处一名仪表工在维修一气动蜗杆式切断球阀时,发生CO中毒,经抢救无效死亡。
200×年×月×日凌晨0时30分左右,公司净化工段变压吸附岗位5A气动蜗杆式切断球阀出现故障,净化工段当班副操作工甲某打开旁路,切断变压吸附系统。班长电话通知计控处值班人员。l时l0分左右,计控处仪表工乙某来变压吸附岗位询问情况后,独自一人到现场去查找故障,甲某在操作室操作开关配合,过了一会,甲某出去听乙某说阀门出现故障,需要维修,甲某便回到了操作室。大约十几分钟后,甲某到外面看,没有看到人,以为仪表工回去了,便没有在意。凌晨5时左右,当班另一名仪表工丁某发现乙某不在,就往净化等部门打电话询问,听说乙某在净化工段干完活早已回去时,丁某立即赶到现场寻找,发现乙某躺在变压吸附平台上,许某赶紧喊人抢救,并立即送往医院,经诊断,确认已死亡。
事故发生后,公司立即成立了事故调查小组及善后小组,调查取证,分析原因。经分析认为事故原因为CO中毒,具体原因如下:
(1)5A气动蜗杆式切断球阀阀杆密封垫片不严,虽然系统已紧急切断,但系统内仍有1.6MPa的压力,造成高浓度的CO泄露,致使正在现场拆卸气源的仪表工乙某中毒;
(2)仪表工乙某安全防范意识较差,按规定进行此类作业现场应有2人以上,乙某却独自1人到有毒有害岗位作业,且没有监护人,没有任何防范措施,属违章作业;计控处安全规定明确要求,“到有毒有害区域进行作业,必须同时有2人以上,或必须有监护人,必须佩戴必要的防护器材,采取一定的安全措施”;
(3)公司当班值班长在得知净化工段出现问题时,没有引起高度重视,未及时到现场进行处理。净化工段班长、变压吸附岗位当班副操作工甲某没有很好地配合仪表工工作,巡回检查不力,也是造成此次事故的一个重要原因。
根据以上内容回答下列问题。
1.对于CO中毒事故如何进行预防
2.这起事故起因物、致害物、伤害方式各是什么f这起事故构成什么性质的事故
3.如何现场抢救CO中毒者
