WINSTON-SALEM, N.C. (AP) — Anuncontrolled fire at a fertilizer plant在北卡罗来纳州继续燃烧，周三初，迫使消防员和成千上万的疏散居民留在至少一英里（1.6公里）之外，因为可能有一个大的爆炸。
“The possibility of an explosion has not gone down,” Winston-Salem Fire Division Chief Bobby Wade told reporters at a 4:30 a.m. news conference.
“我们仍然在现场积极燃烧，”韦德说。“过夜的条件没有改善。”
The fire is at the Winston Weaver Company fertilizer plant on the north side of Winston-Salem. The blaze began Monday night, shooting bright orange flames and thick plumes of smoke into the sky.
火灾迅速消耗整个建筑物，它崩溃了。至少90名消防员周一约有90分钟的火灾。但爆炸的风险迫使他们撤退。没有报告伤害。
Since then, drones and a helicopter have monitored the fire from above, and teams of firefighters have been on standby.
北卡罗莱纳Gov. Roy Cooper plans to meet with local leaders in Winston-Salem early Wednesday afternoon and attend a news conference in the city.
It will be a “slow process” before the fire begins to run out of fuel, Wade said. He could not offer a timeline for when people can return to their homes and said fire officials planned to reevaluate the fire Thursday morning as the blaze continues to burn out.
The area that’s been evacuated includes about 6,500 people in 2,500 homes, the Winston-Salem Fire Department said.

Wake Forest University, most of which lies just outside the evacuation zone, canceled classes and urged students in dormitories to stay indoors with windows closed.

当局警告烟雾和差的空气质量约为250,000。Matthew Smith是一个区域国家工作队的危险物质专家，表示，火焰释放的气体更像是可能造成严重伤害的刺激物，禁止肺部状况。
The fire forced the evacuation of the headquarters of The Truth Network, a Christian broadcasting company that owns radio stations in North Carolina, Ohio, Utah and Virginia. It also syndicates radio programs across the U.S.
The network is running prerecorded broadcasts instead of its live programming because radio hosts cannot make it into the studios, according to Truth Network owner Stu Epperson Jr., who lives in Winston-Salem.
But Epperson, 51, stressed that he and his colleagues are far more concerned about the firefighters and people who live nearby. Many listeners are praying for them.
“我们只是真正为上帝的保护而祈祷，无所事事，”Epperson说。“我们的祈祷是向所有邻居和居民以及被流离失所者流离失所的肥料厂的人，特别是我们的第一个受访者和消防员的人。”
