雪佛龙埃尔塞贡多炼油厂火灾已被控制；调查正在进行中
摘要
雪佛龙埃尔塞贡多炼油厂发生火灾，火势已被控制，无人员受伤；当局正在调查火灾原因。
周四晚，加利福尼亚州雪佛龙埃尔塞贡多炼油厂发生重大火灾，火焰照亮夜空，远处可见。火灾于晚上9:30左右在负责生产航空燃油的Isomax 7装置发生。包括炼油厂自有消防队在内的应急队伍迅速响应，于周五凌晨前控制住火势。无人员受伤，所有员工均已清点完毕。
附近地区居民，如曼哈顿海滩，被建议作为预防措施就地避难，尽管未发布正式疏散命令。空气质量监测在夜间检测到挥发性有机化合物含量升高，官员建议若污染水平增加，居民应留在室内。
埃尔塞贡多炼油厂自1911年投入运营，每日加工原油高达29万桶，供应南加州约40%的航空燃油。火灾导致包括催化重整装置、加氢裂化装置和流化催化裂化装置在内的多个装置停产。虽然此次事件预计将导致燃料供应中断，特别是航空燃油供应受影响，但对汽油价格的整体影响预计较小。
雪佛龙及州和联邦机构正在进行调查，以确定火灾原因。
