Company 35 was dispatched for a vehicle fire inside a garage. Chief 35 arrived on scene to find a commercial utility truck fully involved, but outside of the structure. Engine 35, Tanker 3, and Huntingdon Station 3's Tanker assisted with suppression operations. After extinguishment, the adjacent structure was checked for extension (fire spread). There was no extension to the garage, and the box alarm was placed back in service.
