ZAP the Electrical Safety Bird says:
Play safely ... away from any powerlines.
If kites, model airplanes or balloons touch or get stuck in overhead wires, even holding the string or control wire can cause serious injury.
Stay away from areas marked Keep Out or Danger.
Climbing hydro poles, towers or fences surrounding electrical equipment or trees near power lines is extremely dangerous. You could be severely hurt or killed from coming in contact with powerlines or falling.
Never to poke or push things into electrical equipment or outlets.
