This afternoon Swatara Fire-Rescue and mutual aid were alerted to a house fire in the Chambers Hill section of the township.  Immediately after dispatch units from other departments a large column from miles away.  Engine 91(w/4) responded in less then two minutes and requested the working fire assignment.  Engine 91 arrived and secured its own water and found fire throughout the first floor and basement. A partial collapse to the rear of the house caused crews to switch to a defensive attack.  Crews were out for several hours with extensive overhaul and clean up.
