Fifteen people are unaccounted for following multiple explosions and a fire at a Blue Rhino facility in central Florida, said John Harrell, a spokesman for the Lake County Sheriff's office. Seven people have been transported to regional hospitals, he said. An evacuation area of half a mile has been extended around the plant. There were 53,000, 20-pound cylinders of propane at the facility at the time of the fire, Harrell said. Fire crews could be seen pouring water onto the facility. The cause of the explosions and fire was not immediately known.
