How to Buy Dry Ice

Dry ice is just the solid form of carbon dioxide, which is a significant greenhouse gas in our planet’s atmosphere. It can be used to perform various exciting things, such as creating fog effects. It is effortless to buy, but there are some things you need to keep in mind beforehand. These are given below.

Buying and transporting dry ice

1. Purchase it from the store or e-store– You can purchase the dry ice from your local grocery store. Walmart and Safeway are some stores that sell dry ice. It is very cheap.
2. Identity proof is necessary– Try to buy the dry ice very close to the time when you use it because it tends to change its physical form from solid to gas very quickly. This process is called sublimation. It possesses a short shelf life as it takes only 24 hours for 5-10 pounds of dry ice to convert from solid to gas form. While it is easy to buy, some stores will sell you only if you are at least 18 years old.
3. Forms of dry ice– The dry ice comes in two different forms, namely the block and the pellet form. Buy the dry ice in block form if you want to use it in school experiments or creating fog effects. The dry ice in the pellet form is used for medical transportation.

It is usually cheap. However, the price of dry ice may vary based on location and amount. The typical cost of the dry ice ranges anywhere from $1 to $3 per pound.

Storing and handling dry ice

1. Storing dry ice– Always keep the dry ice inside insulated containers like a plastic cooler or an ice chest. The average refrigerator or freezer is not able to maintain the cool of dry ice. To slow down the sublimation process, avoid opening and closing the container often. It is the fact that the dry ice is much colder than any traditional freezing containers. Thus, it would not be kept cool by using your average refrigerator or freezer. You must use a thick insulated ice chest or cooler to slow down the sublimation of dry ice.
2. Wear leather gloves to handle dry ice– Dry ice can be harmful and prolonged contact with skin is enough to freeze the cells and burn you like fire. You have an option to use an oven mitt or towel as well. However, this stuff will not offer the same protection that gloves provide.
3. Curing burns caused by dry ice– You should treat dry ice like how you treat hot frying pan. It means you must keep your skin out of the contact. In addition to this, you should treat the cause of the burn from dry ice like any typical burns. The red skin can be healed in time.

If your skin comes off or blisters, then you must apply antibiotic ointment and wrap a bandage on that area. You must consult a doctor immediately if the burns are extreme.

Things to avoid while using dry ice

1. Precautions to use Dry Ice– Always keep the dry ice in a well-ventilated place. Dry ice is solidified carbon dioxide, which can be harmful to inhale in large quantities. Large amounts of dry ice kept in airtight place can cause an oxygen-deficient atmosphere. Please keep it away from the reach of young children and pets. While transporting it in a car, always rolls down the window to make space well ventilated.
2. Do not leave dry ice unattended– Dry carbon is very reactive. Thus, even when no one is around, the spills and various other accidents can occur if it is not kept under strict supervision. All you must do is never leave dry ice on any solid surface as the extreme cold could crack it.
3. Do not dispose of dry ice in the sink, garbage disposal, sewer, or toilet– It is an honest mistake that you will end up freezing the water in pipes. You should know that the extreme compactness of the pipe will end up drying ice that can cause a massive explosion.
