Six workers received serious burns after an electrical explosion at Priest Rapids Dam on October 8th 2015.
All the injured received serious burns. Two of the six workers remain at Seattle's Harborview Medical Center. One remains in serious condition in intensive care but is awake and alert, hospital spokeswoman Susan Gregg said. The condition of the other has improved from critical to serious, she said.
Both of the men are in their 40s and undergoing burn surgeries, she said.
The employees were in the vicinity of the dam's P8 generating unit, when the main breaker that turns the unit on or off failed, causing the arc flash explosion, PUD spokesman Chuck Allen said last week.
An arc flash is a phenomenon where an electric current leaves its intended path and travels through the air from one conductor to another, or to the ground, according to workplace safety bulletin on the Occupational Safety and Health Administration (OSHA) website.
