A Bulloch County man was rescued Thursday after falling about 20 feet down a vertical grain-elevator shaft, but did not escape serious injury. While helping construct the elevator, on a site just off Nevils Groveland Road in Nevils, a millwright identified by a co-worker as 64-year old Charles Edward Thomas, 64, plunged from a steel I-beam that stretched across the top of the shaft, face-first, to the metal floor. Bulloch County and Statesboro fire crews pulled Thomas from the shaft shortly after 4 p.m. At approximately 6 p.m., a spokesman for Memorial Health University Medical Center in Savannah said the man had been admitted to the emergency room, and was in stable condition “He was standing on steel I-beam over the hole, lost his footing — he wasn’t anchored down to anything — and fell in face-first.
