The most important thing to remember is: keep the refrigerator and freezer doors closed!
- A refrigerator will keep food cold for about 4 hours if the door is kept closed.
- A full freezer will keep temperature for about 48 hours (24 hours if half-full). If your freezer is not full, group packages so they form an “igloo” to protect each other. Place them to one side or on a tray so that if they begin thawing, their juices won’t get on other foods.
- If the power is going to be out for an extended period of time, buy block ice to keep the refrigerator as cold as possible.
