2008年6月6日,8炼油厂油罐区的2号汽油罐发生火灾爆炸事故,造成1人死亡、3人轻伤,直接经济损失420万元。该油罐为拱顶罐,容量200m3。油罐进油管从罐顶接入罐内,但未伸到罐底。罐内原有液位计,因失灵已拆除。2008年5月20日,油罐完成了清罐检修。6月6日8时,开始给油罐输油,汽油从罐顶输油时进油管内流速为2.3~2.5m/s,导致汽油在罐内发生了剧烈喷溅,随即着火爆炸。爆炸把整个罐顶抛离油罐。现场人员灭火时发现泡沫发生器不出泡沫,匆忙中用水枪灭火,导致火势扩大。消防队到达后,用泡沫扑灭了火灾。事故发生后,在事故调查分析时发现,泡沫灭火系统正常,泡沫发生器不出泡沫的原因是现场人员操作不当,开错了阀门。该厂针对此次事故暴露出的问题,加强了员工安全培训,在现场增设了自动监控系统,完善了现场设备、设施的标志和标识,制订了安全生产应急救援预案。预防此类火灾爆炸事故发生的安全技术措施包括()。
