Tulsa Fire Fighters worked through the night at Tulsa's Port of Catoosa.
Shortly after 2 a.m. on Saturday, fire alarms started sounding in the Advance Research Chemical facility at the port.
Three employees were inside the building at the time. The Tulsa Fire Department responded and quickly got a handle on the situation. No one was injured.
The roads leading to and from the port were closed overnight as a safety precaution.
