GE spokesman Sean Gannon says the dead worker is not a GE employee, but works for an unspecified contractor who was performing maintenance at GE Energy's Pittsburgh Servicing Center in West Mifflin, about five miles east of the city.
GE isn't saying how the worker was killed. Emergency dispatchers say the accident was reported about 8:45 a.m. Thursday.
Gannon issued a statement saying GE is still investigating the accident and "working with the appropriate authorities as required to assess the situation."
The statement goes on to say that GE's primary concern is ensuring the safety and security of our employees, as well as others on-site."
The Allegheny County medical examiner didn't immediately release the worker's name.
