Eastside Fire & Rescue crews responded Tuesday to a report of a fire in North Bend – and when they arrived on scene they found smoke and flames pouring from one of their own fire stations.

The incident unfolded just before 3 p.m. Tuesday when firefighters responded to a fire alarm at a building at 42804 SE 172nd St. in North Bend. Turns out that’s the address of Eastside Fire’s Station 88 in the Wilderness Rim area – a volunteer station that is not staffed full time.

Smoke was billowing from the building when crews arrived on scene. The flames were extinguished, and firefighters discovered that the flames had erupted from an ambulance parked inside the building’s apparatus bay.

The station’s sprinkler system prevented the blaze from spreading.

Fire officials say no one was in the building when the fire started, and it’s unclear why the ambulance burst into flames.
