Dry ice is easily one of the coolest substances around, but it can also be dangerous. Whether you’re going for a lightweight way to keep food cold on your hike or trying to rig up the perfect smoky cauldron, you should read up on these dry ice safety tips before you use it this fall.
Dry ice is extremely cold, about -109 degrees Fahrenheit. If you’re going to have to touch it, you should always protect your skin. Leather gloves are ideal, but even an oven mitt or a towel will work when handling dry ice. The key is that your skin should not have prolonged contact, since that could result in a severe injury similar to a burn.
Dry ice should be stored in an insulated but not completely airtight container. When dry ice sublimates, it turns into CO2 gas, which could cause an airtight container to expand or possibly even explode. While dry ice is a good way to keep the food in your refrigerator/freezer cold during a power outage, it should not be stored in a working freezer. Dry ice doesn’t melt, so storing it in a freezer will not make it last longer. Instead, the extreme cold will cause your freezer to turn off and the dry ice will be used up more quickly. Finally, don’t leave dry ice sitting out directly on countertops, since the extreme cold could cause them to crack.
Since dry ice sublimates into Carbon Dioxide (CO2) gas rather than melts like regular ice, it is important to keep the area well ventilated. Normal air is only 0.035% C02, 21% Oxygen, and 78% Nitrogen, and situations where the CO2 rises above 0.5% can be dangerous. If you are transporting dry ice in the car, keep the windows down or the air circulating with outside air. If you have to leave the dry ice in a closed vehicle or room for more than 10 minutes, air the vehicle or room out thoroughly before entering.
Dry ice “burns” should be treated like regular heat burns: if the skin blisters or peels, see a doctor, otherwise apply antibiotic ointment and bandage only if needed.
