Around 1840 hours, B platoon members were alerted for a structure fire at 1615 Derry Street in the Allison Hill section. First arriving units had heavy fire to the rear of a vacant, 3 story, frame duplex. High winds helped fanned the blaze to the second floor and roof of the fire building and the occupied exposure. 2nd and 3rd alarms were quickly struck bringing the remaining city units and county mutual aid. All companies were put to work chasing the stubborn fire. The fire was placed under control at 1947 hours. Units on the scene: Squad 8, Wagon 3, 4, Tower 1,2,3 (Harrisburg City), Engine 301 (Penbrook), 37-1 (Rescue), Truck 12 (Lower Allen), 32 (Progress), Rescue 69 (York Co), Air 13 (West Shore Fire). This was the first of two three-alarm fires to stike the city within hours of each other.
