At 0035hrs (1235 AM) Dorchester Central dispatched units for a "Working Structure Fire". Units arrived on location to find fire through the roof and requested a 2nd alarm assignment (adding additional units/firefighters to the call). The fire was knocked (extinguished) using multiple attack lines (hoses) from the first arriving engine (Engine 1-3) approx. 900' of 5" supply line (hose) and at least 1 attack line (hose) from Rescue Engine 1-1 on side charlie (rear). While no firefighter was transported to the hospital multiple firefighters fell through the floor. DCEMS transported 1 patient (resident) from the scene to the local hospital (DGH). Salvage/overhaul was complete and all units cleared the scene without incident. This fire remains under investigation via the State Fire Marshal's office.
