At 2057 hours Box 38-7 sent companies to 762 Sunbeam Drive for a reported structure fire. Additional reports indicated fire on the first floor extending to the second floor. Captain 38 arrived on location reporting a working fire, thru the roof. The fire involved an occupied, one and two-story, ranch-style, dwelling. Engine 38 (Dauphin-Middle Paxton) arrived and crews stretched two attack lines to the interior as box alarm companies began to arrive. Command 38 requested three additional tankers to the scene as lack of hydrants in the area made water supply an issue. The fire was knocked down in about 30 minutes and companies performed extensive overhaul. All occupants were reported out of the structure prior to arrival of FD.
