Police are investigating whether representatives of Fortum, which owns the plant where the accident took place, should be held criminally responsible.
The 56-year-old, who is employed by ABB, had gone to the plant with a workmate to perform repairs on a faulty transformer. His colleague left the distribution plant temporarily to make a phone call checking that the transformer’s electricity supply had been switched off.
“Somehow the man came into contact with parts that contained an electrical current. He got the current through his head and back out through one of his hands.
“When his colleague returned, the man was lying on the floor in convulsions. He did however retain consciousness, even when he was taken to hospital in an ambulance,” said police spokesman Bjarne Andersson.
The man suffered some memory loss but escaped with fewer burns than initially expected.
