How to use dry ice during a power outage

Dry ice can be a valuable resource during power outages for various purposes. It is the solid form of carbon dioxide and is extremely cold, making it an effective tool for keeping things cold or frozen without the need for electricity. Here are some common uses of dry ice during power outages:

  1. Preserving perishable food: One of the primary uses of dry ice during power outages is to keep refrigerators and freezers cold when electricity is unavailable. Place blocks or pellets of dry ice in coolers or insulated containers along with your perishable food items. This can help maintain the low temperature and extend the shelf life of your food until the power is restored.

  2. Medical and pharmaceutical storage: If you have medications or vaccines that require refrigeration, dry ice can be used to maintain their temperature during a power outage, preventing spoilage.

  3. Temperature-sensitive equipment: In some cases, dry ice can be used to cool down sensitive electronic or scientific equipment that requires specific temperature ranges to operate correctly.

  4. Comfort cooling: During power outages in hot climates, dry ice can be placed in well-ventilated areas to provide some relief from the heat.

It's important to handle dry ice with caution as it is extremely cold and can cause frostbite if it comes into direct contact with skin. Always wear gloves or use tongs when handling dry ice, and never store it in an airtight container, as it can cause a buildup of pressure.


Be sure to follow proper ventilation guidelines when using dry ice indoors, as carbon dioxide buildup in enclosed spaces can be hazardous. Always consult with a professional or follow safety guidelines provided by the dry ice supplier.
