Safety and Handling
DO NOT leave Dry Ice unattended around children.
DRY ICE IN COOLERS
- Protect Your Hands. Oven mitts, leather gloves, or thick hand towels can prevent freezer burn when handling dry ice.
- Ventilation. Sublimating dry ice gives off a fog (carbon dioxide gas) that can be dangerous if in a confined space. Use dry ice outdoors or in ventilated areas.
- Fortifier. Dry ice can be used in combination with cubes or blocks of water ice. Solid CO2 will help keep frozen H2O longer.
- Wrap It. Confine blocks of dry ice in several sheets of newspaper or towels to slow the sublimation process so ice keeps longer.
- Pack on top. Dry ice can be loaded on top or below food in a cooler. YETI notes food is kept cold longer when dry ice is packed closer to the food.
- No dead space. When packing a cooler, minimize air pockets to keep dry ice frozen longer. Water, ice or a towel can be used to fill in open spaces in a cooler.
- Cover the cooler. For maximum chill, store your cooler in shade and cover it with a blanket or sleeping bag.
