E钢铁公司棒材厂的加热炉使用煤气为燃料。2012年1月9日8时,棒材厂1号加热炉停产检修,更换煤气阀组后面的补偿器。11时更换完补偿器后,由工长甲负责组织引燃煤气。按照引气操作程序,先用氮气对加热炉进行吹灰置换,经检测合格后才能引燃煤气点火。 工长甲让维修工乙和丙两人去开阀组后面的截止阀,两人合力未能打开。乙取来一个铁质扳手。11时35分,乙在松动截止阀的紧固螺栓时,扳手与螺栓撞击产生了火花,遇到泄漏的煤气着火。工长甲在现场立即拿灭火器灭火,但由于火势太大无法扑灭,现场火势迅速蔓延并发生爆炸,乙当场死亡,丙被烧伤。甲手足无措,带着丙慌忙离开现场并赶赴医院。事故后调查发现,由于阀组前球阀密封不严,煤气从密封处泄漏,扩散到截止阀处。 事故造成的经济损失包括:设备损失500万元,处理事故和现场抢救费用30万元,停产损失300万元,丙住院治疗费用80万元,支付乙家属抚恤金25万元,丙歇工工资3万元,事故罚款15万元,补充新员工培训费1万元。 为了预防事故发生,该企业决定按照《企业安全生产标准化基本规范》(AQ/T9006—2010)建立安全生产标准化,提高企业安全管理水平,最终评定为标准化三级。 根据以上场景。回答下列问题: 为防止此类事故再次发生,E钢铁公司棒材厂应采取哪些安全措施
