At 16:15 hrs. ETFC was dispatched (as one of many mutual aid companies) to Aronimink Dr. in Newtown Square for a house fire. NTSFC knocked the main fire down while we and other mutual aid personnel assisted with searching for additional fire. Visible smoke outside indicated the fire was not completely out. After removing a lot of the ceiling to expose the frame work, more fire was spotted and extinguished. After cleanup all mutual aid companies were released by NTSFC.
