How to Store Dry Ice: 14 Steps (with Images)

Dry ice is composed of solidified carbon dioxide and is very cold. It has many uses, despite being applied, in most cases, to fresh produce. One advantage of dry ice is that it does not leave any liquid when it dissolves, as it undergoes sublimation, meaning that it becomes a gas when it reaches -78 °C. Dry ice can be very dangerous, as well as potentially causing severe burns and freezing, so knowing how to store and handle it is extremely important.


Method 1 of 2: Storing Dry Ice

Store Dry Ice Step 1

Step 1. Buy dry ice around the time it will be used

Although the sublimation process can be slowed down, there is no way to stop it. Therefore, it is important to purchase it as close as possible to the time it will be used. Per day, from 2.2 kg to 4.5 kg of dry ice will be lost, even if stored well.

Step 2. Put on insulating gloves and protect your arms

Dry ice can burn the skin due to the extremely low temperature, requiring insulating gloves to protect the hands from freezing and burning when handling. Avoid, as far as possible, direct hand contact with dry ice. Furthermore, wearing long sleeves can protect your arms from the effects of the product.

Step 3. Keep the ice dry in a well-insulated container

A thick Styrofoam cooler is a good option for keeping dry ice in solid state for a longer period of time. Regular coolers can also be used, such as those that store cold drinks.

Step 4. Place crumpled paper in the container

Cover it with crumpled paper so that the sublimation process is slowed down (since it reduces the empty space of the container).

Step 5. Keep container closed when possible

The more it is opened, the more hot air will enter, increasing the sublimation process, which means the dry ice will sublimate much faster.

Step 6. Place the cooler in a cool place

If the weather is cold, keep it outdoors; if the weather is hot, leave the container in a cool, indoor location. Basically, the cooler's external temperature should be as low as possible, as it slows down the sublimation of ice.

Step 7. Watch for burns

If you suffer a slight burn that only causes redness, it should heal on its own; however, if blisters are present or the skin is peeling from dry ice, it is necessary to see a doctor.

Method 2 of 2: Avoiding the Hazards

Store Dry Ice Step 8

Step 1. Keep the ice dry in a ventilated place

As this product releases carbon dioxide, it can be harmful to humans indoors. Make sure there is plenty of fresh air entering the room where the dry ice is stored. Otherwise, it can cause suffocation in people and animals.

Keep in mind that a closed car is an area with no ventilation, especially if the air conditioning is turned off. Don't leave dry ice inside a parked car; during transport, open the windows or make sure the air conditioner is turned on so that fresh air enters the vehicle. Also, keep dry ice well away from you while driving

Step 2. Do not use an airtight container

Dry ice sublimes and does not melt, which means it releases carbon dioxide; as soon as it turns into a gas, there must be space for the carbon to come out. In hermetically sealed containers, gas can expand too much, causing an explosion.

Step 3. Do not put it in the freezer

It is hermetically sealed, so there is a danger of dry ice explosion. Also, putting dry ice in a refrigerator can destroy the system, as thermostats cannot withstand such temperatures.

Step 4. Put on glasses and face shield when breaking the ice

If you need to break a block of dry ice, wear glasses to protect your eyes and face, as there is a risk of the ice getting into the person's eyes, causing burns.

Step 5. Don't go near low areas

Carbon dioxide tends to accumulate at the bottom of the container as it is heavier than the air you breathe. Soon, it accumulates in low areas. Do not put your head near such places.

Step 6. Beware of surfaces where ice is placed

It can damage them due to extremely low temperature. The surfaces of certain countertops or tiles may crack when they come in contact with dry ice.

Store Dry Ice Step 14

Step 7. Dispose of dry ice properly

The best way to dispose of unused dry ice is to let it sublime. Make sure the room is well ventilated when transforming dry ice to gas.

Do not put dry ice in a sink or toilet, as they can be destroyed. Also, do not put it in wastebaskets or leave it in places where it might accidentally come into contact with people or someone who is not aware that they are touching dry ice. The risk of severe burns will be very high
