The Carrollton Fire Department rescued a construction worker trapped in a hole at Goode Elementary at 1012 Study Lane.
The 19-year-old man was pulled from the hole just after 4:30 p.m. an awaiting ambulance took him to a CareFlite chopper at a nearby parking lot. He was flown to Parkland Hospital for treatment.
Carrollton Fire and Police dispatchers said the worker fell down the hole at around 3:15 p.m. and hurt his back but was alert and speaking.
The pier hole was 55 feet deep and 33 inches wide according to Gregg Salmi with the Carrollton Fire Department. Fire officials said the man fell all the way to the bottom of the hole and only had use of one arm because of the way he fell.
A large black hose was used to give the man air during the hour and a half rescue.
Carrolton-Farmers Branch Independent School District said the man is employed by Texas Shaft, one of the contractors working to rebuild Goode Elementary.
Occupational Safety and Health Administration will investigate the accident.
