Activities

Background Info

Electrical safety tips around power lines

  • Don't climb on power poles
  • Never fly kites near power lines
  • Stay away from broken or fallen power lines
  • Never touch or climb trees that are near power lines
  • Never touch big, metal transformer boxes with warning signs
  • Obey warning signs
  • Stay away from substations and power lines

Electrical safety, electricity and power lines 

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 kite gets tangled in a power line, the electrical current could travel through the kite 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.  

If there is a power line on the ground, you need to move away from the source (where it touches the ground). However electricity has the ability to move through your body as you step away from the source of electricity. As electrical current flows through the ground the voltage decreases in concentric rings or ripples as you move further from the source. So, if you move away by lifting one foot, the change in voltage between the concentric rings can travel up one leg and down the other. Instead by keeping your legs together and shuffling your feet, the electrical current will stay in the ground. 10 metres is the safe distance calculated based on the voltage in the power lines here in B.C.


Assessments

The activities in this lesson provide an opportunity to assess individual students and groups on their ability to:

  • Identify safe and dangerous situations around power lines
  • Learn Down. Danger. Dial 911 in response to a hazard like a downed power line
  • Learn how to shuffe away from a downed power line to at least 10 metres in distance
  • Estimate a 10 metre distance
