A laundry room fire Sunday afternoon at Pilot Butte Rehabilitation in northeast Bend was stopped by the facility’s fire sprinkler system, an official said.

A fire alarm report was received by Bend Fire & Rescue just after 3:30 p.m. It soon was upgraded to a structure fire response after staff found smoking coming from the laundry room of the facility, in the 1800 block of Northeast Highway 20, Deputy Fire Marshal Jeff Bond said.

Crews arrived to find that the sprinkler system had activated and completed putting it out, Bond said. There were no injuries and minimal heat and water damage. No smoke entered the patient area of the building, the official added.

The exact cause of the fire was under investigation, Bond said. The fire sprinkler and alarm systems were back in operation in about two hours.
