美国东部俄亥俄州与宾夕法尼亚州交界地带,3日晚间发生化学原料列车出轨的意外,并且引发大火,目前火势虽已获控制,但由于列车所运送的氯乙烯可能致癌,因此有关单位对当地约5000居民发出紧急疏散命令,这起事故的原因则有待调查。
美国有线电视新闻网(CNN)报导,1列长达100节以上的货运列车,3日晚间行经宾州与俄亥俄州交界地带的东巴勒斯坦(East
Palestine)时,载运有毒物质的20节车厢中,有10节发生出轨意外并引发大火,美国国家运输安全委员会(NTSB)证实,在出轨的车厢中有5节装载氯乙烯(vinyl
chloride),并有部分气体已透过列车的减压装置排出车外,但无法确定是否有大量物质外洩的情形,所幸目前尚未传出有人员伤亡的消息。
NTSB委员葛拉罕(Michael
Graham)在记者会中表示,目前火势虽已被控制,但仍无法预估何时可被扑灭,在取得影像与行车资料后,将需要4到6周的时间,才能完成初步的事故报告。
俄亥俄州环保局表示,目前事故发生区域空气中的有害物质并未超标,但强调将持续监控,当地政府则在避免民众生命财产与健康受到威胁的考量下,已开设两处避难中心,并对约5000名居民发出紧急撤离的命令,待威胁结束、安全无虞后才会解除。
