Electricity always poses a hazard to small children and a range of electrical safety items are available to help reduce this hazard.
Every home with small children should have Outlet Plugs inserted throughout the house into every wall plug that is within reach of young children. They are one of the least expensive of all safety products and can help to prevent a nasty, and potentially life-threatening, shock.
Also make sure that you have an RCD installed in your home and that it is in working order. An RCD is a safety device that switches off electricity automatically if there is a fault of some sort, to reduce the risk of electrocution and even fire. Contact an electrician for advice in this regard.
