No injuries after a nitrogen leak at Queen City Steel Treating Co. on Spring Grove Avenue. The Cincinnati Fire Department reports a Medic Unit discovered the leak after returning from taking a patient to the hospital. The leak created a vapor cloud that covered Spring Grove Avenue in Camp Washington and nearby residents were evacuated or sheltered on upper floors.
The Cincinnati Police worked with the Fire Department to isolate the area and allow the nitrogen to evaporate. Spring Grove and nearby streets were closed until 6:00 A.M.
The release says It appears that thieves may have broken into a secure area and were attempting to steal copper. The exact cause is still under investigation.
More than 40 firefighters were required to isolate the area.
