Pawtucket, RI – The day shift was performing mayday and rapid intervention training as fire alarm phones were ringing reporting a dwelling fire at 181 Harrison Street around 1130hrs on June 2, 2009. As companies broke away from the drill numerous calls were tended for this address. Engine 2 arrived to find heavy smoke pushing from all floors on side 4 of this partially occupied 3sty balloon framed dwelling. The driver pulled his rig past the structure to leave room for the truck work and next due units. Heavy fire was venting from side 2 on the first floor as Engine 2 was placed into pump. The fire was starting to melt the vinyl siding of 185 Harrison due to the radiant heat. Ladder 2 set up its stick to the roof on side 4 and began to open the roof. Several lines were stretched to the fire floor and above levels to stop this blaze. Primary searches were aggressively performed due to reports of a trapped occupant on the fire floor. Searches proved negative for this occupant but a canine was removed to safety by the Jakes.All of the cities companies were eventually on scene due to the size of the dwelling and fire conditions on arrival. The first floor of the dwelling was gutted by the rapid fire spread and overhaul. The second and third floors were reported as vacant. The cause of the fire is under investigation by the Fire Prevention Bureau of the Pawtucket Fire Department.
