I was in Bloomington when this story broke.....
In the 60s, Westinghouse built PCB filled oil circuit breakers and transformers for power sub-stations and on the poles at a plant in Bloomington, IN. It was a very long plant and could take quite a bit of time to walk from the back to the front.
A series of production units started failing in the field.
Research of the serial numbers showed that the problem units were produced around the time of the late night break. Further research showed these units were at the back of the plant at that time.
A group of Uker (Card game) players did not want to miss out on their break card game time as the restrooms were in the front of the plant, so they voided their bladders into the open canisters. Over time, the uric acid ate of the insulation on the wires and the transformers would short out.
So that stuff can be corrosive!
