At 14:14 Station 98 was dispatched for wires down at 248 Glenside Ave. C98 arrived and reported a downed tree had pulled the power lines away from the dwelling and were still energized. Upon further investigation smoke began to show from basement windows and the basement doors of the home. Entry was forced and R98 stretched a hand line to the basement. The fire was quickly knocked down and held to only the basement. The fire was caused by a power back feed due to tree bringing down the wires. L30, E30, E312, E32 and SS10 assisted. C98 had Morrisville command and Station 98 was available at 15:50.
