Emergency crews remained Monday morning at an ice plant at Corbin that was heavily damaged by fire.
Corbin Police Maj. Rob Jones said just before 7:30 a.m. that crews were fighting hot spots and that traffic in the area was being disrupted.
The blaze broke out about 1:20 a.m. at the Corbin Ice Co. on Cumberland Falls Highway, Jones said.
He said the blaze caused extensive damage.
"Fortunately, the fire did not get to the anhydrous ammonia," he said. "It it had, we would have much bigger problems."
Anhydrous ammonia, a gas used in commercial ice-making, releases pungent, suffocating fumes.
Jones said a tanker truck was being summoned to remove the material from the fire site.
The cause of the blaze hasn't been determined, Jones said.
