At 1447 hours, Box 81-1 sent Company 48, Engine 54, and Tankers 2, 54 to 3692 Old Hershey Road for a house fire with possible entrapment. Responding units were advised of multiple calls being received. Engine 48 arrived with heavy fire from the rear of a 2 story dwelling and immediately went in service with lines and a search of the dwelling. Fire also involved a multi-bay, garage and autos attached to the rear. Additional resources were requested to the scene as the area lacked hydrants. All occupants were accounted for. Several lines were stretched and companies were able to keep the fire to the rear portion of the dwelling. Units remained on the scene for an extended period of time performing overhaul and securing a large propane tank.
