Fire crews from Fire District 20 in Skyway and the Boeing Renton plant helped battle a fire at a BPA power station near Ravensdale Monday evening.
An explosion, then smoke and flames were reported at just before 5:15 p.m. at the power station at 30725 S.E. Retreat-Kanasket Road, according to Dave Nelson, a spokesman for Fire District 20.
King County Fire District 47 and Maple Valley Fire units responded. Firefighters were kept at a distance for safety because the power station is a major feeder from the Grand Coulee Dam to local utility companies around Western Washington, according to Nelson
Residents near the power station were advised to stay inside because it wasn't known immediately what was burning and the potential existed for another explosion. That order was lifted at 7:30 p.m., when it was determined that mineral oil was burning and the fire had decreased.
Fire and BPA officials toured the area of the power station before 9 p.m. to get a close view of the fire and damage. At about 11 p.m. the station was taken completely offline and a tanker truck from the Boeing Renton plant got close enough to use fire hoses to put a special foam agent on the fire and to cool the transformer.
The Bonneville Power Administration is handling the investigation into the cause of the explosion. There were no injuries to firefighters or the public.
More than 40 fire personnel responded at the peak of the call, including those from King County Fire District 47 in the Palmer-Selleck, Maple Valley, Kent, Skyway, Boeing (Renton plant), King County Medic One and Zone 3 Rehab.
