Dry ice may be the best way to keep your frozen and refrigerated foods from spoiling in the event of a power outage. At a temperature of -109°F, dry ice can replace the cooling power of your refrigerator or freezer.
During a power outage, place dry ice on the top shelf of the freezer and the bottom shelf of the refrigerator. If you are evacuating an area, dry ice in a cooler will allow you to transport perishable food or medicines while traveling.
Continental Carbonic locations have charts available to help determine how much dry ice is needed.
