The explosion came early Wednesday and blew out windows, damaging the buildings interior. No one was hurt as a result of the explosion, but the building was closed. "We arrived on scene and we found what appeared to be a large propane tank on fire on the outside of the building," said Lt. Mike Budreau. "It had caused some damage to the building. There was some glass breakage and there was some interior damage. But most of the damage appears to be on the exterior, which is good."
