UPDATE: A workplace accident Tuesday at the Baylor School had first responders swarming to the school located on the banks of the Tennessee River.

Initial reports are that a concrete pump "blew up" in a worker's face near the school's back exit, where the tennis and soccer complexes are located. The fire department is calling it an industrial accident.

"A piece of pumping equipment that was used to pump concrete from a concrete truck into the tennis facility was being used and that piece of equipment that was being used as the pump is what actually malfunctioned and failed," said Captain Chuck Hartung of the Chattanooga Fire Dept.

Work is being done on the indoor tennis courts during the school's Christmas break.

The worker sustained traumatic facial injuries and was transported to a nearby hospital for examination and treatment.

The call came in at 11:11 a.m. and fire crews were on scene by 11:15 a.m. The ambulance had left for Erlanger by 11:30.
