Sparky the dog is lost. Can you help find him while remembering to stay safe around electrical hazards?
Sparky the dog is lost, and you can help find him by making safe, power smart choices. Your journey to find Sparky will take you through several real-life scenarios. The decisions you make along the way will help you learn about electrical safety.
Power lines are conductive meaning the electrical current runs through them with the least resistance. However if something makes contact with a live power line like a tree, kite, or ladder, the electrical current may flow to the ground. The place where the current touches the ground is the highest voltage and from that point the electrical current spreads out in irregular concentric circles. The voltage or electrical intensity decreases as it moves further from the source. A safe distance from the source of contact, like a downed power line, is 10 metres or more.
Electricity has the ability to find its way through touch to get to the ground. If a tree branch gets tangled in a power line, the electrical current could travel through the branch and you to reach the ground. Birds do not get zapped when standing on a power line, however they would if they straddled two power lines, or touch their beak to the ground while standing on the power line.
