Providence, RI - Fire Alarm received calls for a vacant dwelling fire in the area of Kossuth and Hyat Streets in the Manton section of the city around 2100hrs on March 08, 2009. Engine 15 arrived first due finding heavy fire in a vacant 3sty 40x60 wood framed dwelling extending to a similar structure on side 2. Heavy fire was pushing from all floors up to the attic in this balloon frame mansard roofed structure. Engine 15 requested a quick second alarm to be struck due to the overlapping fire. Several "big" lines were stretched to protect the exposures and to start knocking the fire down. Tower Ladders 1 and 2 set up their waterways on Kossuth Street side to blitz the original fire building. The siding on the exposure suffered heavy damage with some minor extension inside the dwelling. Firefighters were allowed to re-enter the dwelling to chase hot spots and open up once the bulk of the fire was knocked down. Three injuries to firefighters were reported and the fire deemed suspicious and is under investigation.
