Woonsocket, RI - Engine 1, 2, 3, Ladder 1, Rescue 1, and Chief 1 responded to the area of Bell St and Park Ave for a reported dwelling fire on July 14, 2009 around 0030hrs. Engine 1 arrived first due and found heavy fire extending from the basement to the third floor on side 3 of this 50x70 2.5sty wood frame vacant dwelling. The rapid deployment of the first attack line knocked the bulk of the heavy fire down in minutes in the rear of the dwelling. The fire did however extend inside to all floors and attic requiring interior companies to open up the walls and ceilings to stop the fire spread. Ladder 1 opened the roof on side 4 releasing heavy smoke and then fire to take the heat off of the inside crews. A moderate to heavy smoke condition vented from the structure for minutes questioning the extension inside the building's voids. The smoke lessened up after a quick bottle change and regroup of the Jakes. A quick attack, aggressive overhaul, and wet down kept the roof on this dwelling. This was a great stop by the brother and sister firefighter of the City of Woonsocket Fire Department.
