Around 0620 hours West Shore fire companies were dispatched to 4th Street and Herman Avenue in Lemoyne for a house fire. Multiple calls were being received and PD advise the structure was fully involved. Squad 13 (West Shore Bureau of Fire) went on location with heavy fire on the second floor rear of a 2.5 story, occupied, dwelling. Crews stretched a line up the rear stairs to make a knock on the fire which extended to the attic. Aggressive work resulted in the bulk of the fire being knocked down in 10 minutes with extensive overhaul.
