The BPA (Bonneville Power Administration) is the regional power authority that operates the hydroelectric dams on the Columbia and other rivers here. The transmission lines they send the power out on carry 250,000 volts.
The Snohomish County Public Utility District (the utility I worked at for 30 years which provides the electric service in Snohomish County) has a transmission system that carries power at 115,000 volts from several BPA substations through a network of their own substations. From the PUD substations the power is sent out through a distribution system (the wires that run along the roadsides) at 12,500 volts.
During the 30 years I worked at the electric utility there were a few of fatalities.
One was a couple of teenagers who ignored the warning signs and climbed the fence into a substation. Their parents sued and were awarded a few million dollars.
A lineman was working in an underground distribution vault, and his legs contacted two of the three 12,500 volt bushings on a transformer. It didn’t kill him outright. He died a few months later.
Another fatal accident wasn’t an electrocution. We were having a wind storm, and a 150 foot tree had fallen against a transmission line but didn’t break the wires. It was dark, windy and raining, around 2 in the morning. One of the tree trimming crews were trying to remove the tree without causing more damage. The power had been shut off the the power lines. One of the arborists put on his climbing gear, and went up an adjacent tree, to cut the leaning tree in sections. He cut his climbing rope and fell nearly 150 feet. He left a wife and two children behind.
There was a substation worker who was cleaning bushings on the top of an electric switchgear building in a substation. He didn’t notice his leg touching one bushing, and when he touched the one of other bushings (phase to phase at 12,500 volts each phase) the arc blew him off the roof of the switchgear. He survived but spent years healing from the burns where the current cooked the path it took inside his body.
A warehouseman died when he failed to follow safety protocols and fell from a mezzanine in the warehouse.
A groundman lost a finger when the leather glove he was wearing got caught in a rope. It pulled the glove off of his hand, taking the wedding ring which skinned the finger.
I knew all of these people except the teenagers.
