Four fire departments joined East Pierce Fire and Rescue Thursday around 11:25 p.m. to fight a two-alarm fire at Bonney Lake High School.

East Pierce firefighters responded to reports of flames and smoke coming from the building that houses the food service.

The probable cause of the fire is electrical, according to East Pierce Fire and Rescue Deputy Fire Marshal Brian VanMeter.

The origin of the fire appears to have been a light and ballast in the overhand above the loading dock in the children’s nutrition and food service area of the Sumner School District’s Maintenance Building located near the high school.

Joining East Pierce were Orting Valley Fire and Rescue, Central Pierce Fire and Rescue, Valley Regional Fire Authority and the Buckley Fire Department.

According to a press release, the fire was contained to the attic space in the building.

There were no injuries.
