I chauffeured my wife to a walk-in orthopedic clinic today, where I stayed out in the car while she went in. There was no need for me to sit in the waiting room and the temperatures here in central Florida were in the chilly mid-60°s. While she was inside I went on a quick walk-about with my camera and happened to photograph this odd item bolted to the side of the building. What caught my eye was the text on the sign stating “Possible unplanned release of hazardous gas.” Unplanned I might understand, but what kind(s) of hazardous gas would a health facility release in an unplanned manner?
