SERGEANT BLUFF, Iowa (KTIV) – A Sergeant Bluff business was fully engulfed in flames Friday morning.
The fire broke out just before 6:00 a.m. at Flatbed Services, a trucking company, at 2260 Andrews Avenue, south of Sioux Gateway Airport. Fire departments from Sergeant Bluff, Sioux City and the 185th Air Refueling Wing were called to the scene.
During the fire, there were reports of explosions, which were confirmed to KTIV by the Sergeant Bluff Police Department.
Sioux City Fire Marshal Mark Aesoph says there were numerous propane tanks inside which could be the source of those explosions.
Authorities say no one was inside the building at the time of the fire and there were no injuries.
Aesoph added defensive operations were used, so they could fight the fire from the exterior.
“At that point, everyone went into defensive operations, and all fire fighting was done from the exterior,” said Mark Aesoph, Fire Marshal.
Aesoph says the investigation into the cause of the fire is just beginning and may take several
days to complete.
Firefighters from Sioux City and the 185th are on the scene of a fire at a business near the Sioux Gateway Airport.
It was called in around 6 this morning near 225th Street and Andrew Avenue.
