After it s defrosted, clean it thoroughly. While your freezer is not in use, leave the door open slightly to let air circulate in the food compartments. As a safety precaution for young children, be sure the door is fixed so it can t be closed. If there s no space available in another freezer, use dry ice in your freezer to keep your food frozen. To locate a source of dry ice in your community, check the yellow pages under Dry Ice or Carbonic Gas.
Dry ice is very cold.
Handle it quickly and always wear heavy gloves to prevent the ice from burning your hands. When you buy dry ice, have it cut into small enough sizes to use. Don t try to cut or chip it yourself. Ask the dry ice company to wrap each piece in newspaper for you. Put heavy cardboard on top of packages of frozen food in each compartment of your freezer and put the dry ice on top of the cardboard.
