This is a good reminder of the importance of teaching electrical safety to children and adults alike. I am a big fan of GFCIs and fuses to prevent much of the electrical concerns stated in the article. As a Mom of young children, I used to use plastic covers to childproof outlets. GFCIs are nice but it is also important to instruct children on the dangers of AC outlets in general since not all outlets have them and sooner or later kids will encounter outlets that have not been childproofed. Teaching appliance safety is a top priority as well (don't stick any metal objects in the toaster!) Periodic wiring inspections are a good idea but often hard to implement because of location.
