WE took a Fire Safety Class several years ago ( free Dinner) and they Highly Recommend unplugging most every thing... especially Coffeemakers, Irons, other Kitchen appliances like Microwaves ( if you are going to be gone for more than 1 day, Hair Dryers and Curling Irons, most everything should be plugged into surge strips, and never leave extension Cords plugged in.. like a previous post- the power is still going through the cords... I unplug the Sewing machine if we are going away too. Be Safe, Better to take a few min. plugging everything back in...
