The tendency of small children to stick their fingers in places where they don't belong can sometimes create a problem for mom or dad. But the result can be much more serious in the form of a painful experience, or even a fatality, when children poke around electrical outlets. A Leviton Institute article suggests that you cover exposed electrical outlets with protective devices. There are many types to choose from, including outlet caps that completely close off unused outlets, tamper-resistant outlets, and tamper-resistant wall plates and adaptors. The last one allows you to use an outlet while preventing a child from inserting fingers, pencils or other objects. The article suggests many other ways to protect children from the power of electricity.
