You may be thinking that children of all ages do not need to know about electrical safety, but it is a matter of fact that they do. Children, no matter how young or old they are need to understand the dangers of electricity.
Electricity is one of the most dangerous aspects of our homes, with it simply being able to kill in seconds. So, if you are not giving your children the understanding you are putting them and your home at risk.
So, teach all children from toddlers to teens about electrical safety. Give them the warnings about little fingers in plug sockets. Make teens aware of the dangers of sleeping with their phones under their pillows. Make everyone aware of the dangers of using cheap electrical products.
The damage all of these can cause is not worth the 5 minutes it will take to teach your children about this safety aspect.
