5 Things to Know Before Putting Dry Ice in a Cooler

Most coolers can crack from the cold Dry ice is -109°F, and regular plastic coolers become brittle in extreme cold. Cheap coolers are especially prone to cracking or warping from the temperature shock.

Ventilation is non-negotiable Dry ice sublimates into carbon dioxide gas, which builds pressure in a sealed cooler. Leave the drain plug open or crack the lid slightly to prevent bulging or a CO2 explosion.

Never put dry ice directly against cooler walls or food Wrap dry ice in newspaper or a towel, and keep food in separate containers. Direct contact can damage the cooler and freeze food unevenly.

Rotomolded coolers handle the cold better Yeti and RTIC-style coolers are more durable against extreme temperatures, but they still need a gas escape route. Never lock the lid.

Never touch dry ice with bare skin Always use gloves or tongs. Dry ice causes severe frostbite on contact.
