As both a father and Master Electrician, I am always amazed at how children are attracted to electrical outlets. Often your child is simply trying to help you by plugging in the vacuum cleaner. Unfortunately their act of kindness could have fatal consequences.
The amount of children hurt by electricity per year is staggering. More than 30,000 non-fatal shock accidents occur each year. Every day, approximately 7 children are treated in hospital emergency rooms for electrical shock or burn injuries caused by tampering with a wall outlet.

Perhaps the biggest move towards protecting children from this threat in the home, came with the implementation of the 2008 National Electrical Code, which required all renovated and new residential building to have “Tamper Resident” outlets installed.
If your home is new or has been renovated since 2008 then, in theory, you should already have this basic protection. An example can be seen below.
If you don’t have this type of receptacle , there are still inexpensive options to protect your children from electric shock. Below are some after market options and one of them doesn’t even require tools!
