When the power's out, treat your fridge door like it's made of gold – open it only when absolutely necessary.

And stock up on shelf-stable foods to help keep the coolness inside.

Moreover, if you're feeling munchy, grab something off your table and don't open your refrigerator! Remember, a closed fridge can last four hours, protecting your food from the outside air.
