TULSA, Oklahoma - Tulsa firefighters battled a business fire just after midnight Sunday. The fire took place at Crating Solutions of Tulsa's two-story building at 5199 North Mingo.

Captain Jason Gilkison, Tulsa Fire Department, said the fire started in and was contained to the second-floor break room and office area. Crews extended their fire attack lines deep into the large building to reach the fire.

Gilkison said firefighters also used up a lot of oxygen in fighting the fire. There were flammable solid materials in the warehouse area, but luckily the fire was stopped before reaching them, he said.

The break room and office were a total loss, but the building was left structurally intact.

No employees were in the building when the fire broke out, authorities say. Captain Stan May said the cause of the fire is determined.
