Warwick, RI - A passing Warwick, RI police officer is credited with alerting a family of a fire in their dwelling at 175 Bellman Ave on April 30, 2010. The officer spotted the fire while on routine patrol. Engine 4 arrived to find heavy smoke and fire showing from the C-D corner of a large 2.5sty wood frame dwelling. The crew stretched a 1.75" hand line through the side D doorway to start fire attack on the first floor. The OIC requested the next due companies to perform a secondary search on the upper floors on their arrival to the scene. The searches proved negative as the occupants were safely evacuated to a neighbor's house. Interior companies found that the fire had extended to the walls above the fire floor. A second line was stretched in as companies used hooks to open the walls above the fire. The firefighters also reported heavy smoke and heat in the attic. The roof was then opened to release the trapped smoke, heat, and gases to bring relief to the crew as they searched for further extension. A third hand line was stretched into the attic for a precaution. EMS evaluated the occupants for injuries and smoke inhalation on scene. The Warwick Fire Department Fire Marshal was on scene to determine origin and cause.
