译文：昆明双龙收费站罐车阀漏甲醛
昨天中午12时05分，一辆载有甲醛的槽罐车在经过东绕城高速双龙收费站时，传动轴化工泵
突然断裂导致车底阀门损坏，甲醛泄漏，双龙收费站被迫紧急封闭。收费站工作人员和赶到的消防官兵疏散了附近经过的车流，交警也及时在进出匝道对交通进行分流疏导，槽罐车堵漏倒灌直至下午5时30分才结束，没有造成人员伤亡。
记者赶到现场时，事发区域双龙收费站已经全部封闭，刺鼻的甲醛味迎面扑来，眼睛被刺得难以睁开。行经离心泵
车辆全部被挡在警戒线以外，封闭道路匝道附近，都有路政、交警在疏散积压车辆。发生泄漏的槽罐车停在收费站最右侧车道里，不断有泄漏的甲醛顺着车流到路边。
槽罐车司机说，罐装车中装有10多吨甲醛，是从宜良拉运到双龙乡，他途经双龙收费站时，在小上坡路段停车后，刚一深井泵
抬离合器，传动轴就发生了断裂，并把车底一个四角阀门螺栓打坏，他试了好几次都无法将螺栓拧紧，甲醛泄漏一直都堵不住，他急忙报警求救。
消防队员身着防化服对泄漏点进行堵漏，但还是有少量泄漏持续从损坏的阀门渗出。为避免泄漏出来的甲醛顺着道路对附近村庄造成污染，路政人员在路边用沙土筑了两道土坎。下午1时45分,倒灌的槽罐车赶到，却又无功而返——原来倒灌的槽罐车阀门故障、罐内还计量泵
存有少量柴油，技术人员担心甲醛与柴油混合后发生意外情况，决定再重新调一辆槽罐车进行倒灌。
直到下午5时30分，倒灌终于完毕，故障槽罐车被挪开后，双龙收费站才逐步解除了封闭。
■ 新闻助读
甲醛俗称福尔马林，是无色、具有强烈气味的刺激性气体。人吸入高浓度甲醛后，会出现呼吸道的严重刺激和水肿、眼刺痛、头痛，也可发生支气管哮喘。皮肤直接接触甲醛，可引起皮炎、色斑、坏死。
危险特性：其蒸气与空气形成爆炸性混合物，遇明火、高热能会引起燃烧爆炸。若遇高热，容器内压增大，有开裂和爆炸的危险。
