5 Rules for Using Dry Ice in a Cooler Safely

Never seal the cooler airtight Dry ice sublimates into carbon dioxide gas, which builds pressure. Leave the drain plug open or crack the lid slightly to prevent the lid from popping off or the cooler bursting.

Use gloves or tongs to handle it Dry ice is about -109°F and will cause frostbite-like burns on bare skin. Always wear insulated gloves or use tongs.

Avoid glass or ceramic containers inside The extreme cold can shatter glass or ceramic. Use plastic or metal containers instead.

Keep drinks and soft items separated Dry ice can freeze and burst cans or bottles. Place a layer of cardboard or towel between the dry ice and items you don’t want frozen solid.

Never use it in a small, unventilated space CO₂ displaces oxygen. In a car or small room, the gas buildup can cause dizziness or suffocation. Always ventilate the area.
