Any appliance or tool, especially a powered one, can be dangerous if you do not take the time and effort to understand it, learn how to use it properly. I use a foot switch when I use a drill, an electric saw, etc. I was/am an Eagle Scout, the Safety Merit Badge was one of the required ones, recall learning about carbon monoxide, overloading electrical circuits, etc. Recall learning that when you had a live Christmas tree you had to fill the stand with water regularly. There was a small fire in our apartment complex some years ago, one of those "always on" TVs, they seem to be off the market now.
I remember the Great Northeastern Blackout of 1965-we were just south of it-there was a bad blackout in NYC in the Summer of 1977, when Sandy hit here in October 2012 my town was without power for 5 days, a friend living on the Jersey Shore-9 days. My apartment has an eclectic stove....FAH!!! Get everything on one giant interconnected grid, then something goes wrong, lightning strike, downed wires, overage or defective equipment, human error, poor training and supervision of employees..
