Pruning and removing trees
Falling trees pose serious safety risks
Trees in contact with power lines or wires knocked down by trees can electrocute you and possibly ignite a fire.
If anything makes contact with an energized line, such as a tree, or if a broken power line falls to the ground or lands on a vehicle or fence, electricity will flow to the ground and spread out in irregular concentric circles. This is known as the Ripple Effect.
