月日晚时许，东木头市一天然气调压箱阀门被垃圾车撞断，造成天然气管道发生 锻钢阀门泄漏，导致周边家餐饮企业，余户居民用气受到影响。昨日零时分，险情排除，中午时，停气的单位及住户用气恢复。
事发地在南大街东木头市滚石新天地ktv南侧，一辆垃圾车倒车时，将街边天然气调压箱上的阀门撞断，顿时断裂处发出嘶嘶的声音，还伴有刺鼻的味道传出。发现附近天然气泄漏后，周围群众立即报警。
民警和消防员闻讯赶到现场，对附近楼内人员进行紧急疏散，消防员拿着高压水枪对着空中猛喷，以稀释空中弥散的天然气。晚上时分，西安秦华天然气公司抢修人员赶到事故现场，关掉了天然气总阀，排查后发现，天然气调压箱上的阀门断裂，导致天然气泄漏，随即抢修人员迅速更换了一个阀门。
经过紧急处置，空气中的天然气气味逐渐变淡，险情于昨日凌晨零时分排除。据悉，空气中的天然气含量达到%～%时，是天然气的燃爆点，一旦遇到明火会瞬间发生爆炸，如遇密闭空间将会发生剧烈爆炸，后果不堪设想。但低于或高出这个范围，则不会有闪爆的危险。
为避免发生更严重的事故，日晚时分起，交警碑林大队派出余警力，将现场用隔离墩封锁后，对南大街由南向北三车道进行了临时交通管制。半小时后，经抢修人员要求，西侧两个闸阀车道也被封闭，直至日凌晨时，南大街交通恢复畅通。
昨日上午时，记者来到事故现场看到，一切都已恢复正常。
西安秦华天然气公司企业传讯部王辉说，事故现场地下埋设的管道属于供应居民用气的中压管道，内部压力不大，因此泄漏事故并未造成大范围影响。
