A group of students walking to school use the three keys to electrical safety when they come across a downed power line. This interactive activity gives us the information needed to identify potential hazards in our neighbourhood by watching a video that presents electrical safety scenarios and poses questions to discuss as a class.
A downed line may be on the ground or caught in a tree. Wherever it's landed, it can be a danger to yourself and others.
To be safe, shuffle (don't walk or hop) 10 metres away from a downed wire. Keep others in the vicinity at least a bus-length away.
If you see a downed line, call 911 as soon as you can. Why 911? Emergency services can dispatch a team immediately to secure and keep your area safe, and will contact us right away.

Why do you need to shuffle?
When live power lines touch the ground, electricity flows into the ground and spreads in irregular circles (much like ripples in a pond after a stone is cast). As you get further away from the source, the electrical voltage (potential) weakens (10 metres being a safe distance). Electricity always flows from high potential to lower potential (much like a car in neutral gear rolling down a hill) and the reason why we shuffle is to ensure that your body is on the same voltage level. Humans are very good conductors of electricity; but, if we remain on the same voltage, then the electricity has no motivation to travel through your body (much like a car in neutral gear on a flat street). That’s why birds don’t get electrocuted while perched on power lines: their two feet are at the same electrical potential/voltage.
