Once everyone was out, CFD hazmat crews entered the building and located an active ammonia leak.

“Crews monitored the wind and created a safe zone around the structure, closing off 69 Ave. S.E. in the 2000 block to maintain a safe distance for the public while crews worked to mitigate the hazard,” officials said in a news release.

Hazmat crews then isolated the leak, ventilated the arena and coordinated with contractors to ensure the system was safe for repairs to take place.

No one was injured during the incident and no homes or businesses needed to be evacuated.
