How to Store Dry Ice

Only purchase dry ice when you are close to needing it. You can slow down the sublimation process but cannot stop it entirely. Therefore, buy dry ice only when you are about to use it. Keep in mind that you will lose approximately 2 - 4.5kg of dry ice per day, even when stored correctly.

Wear insulated gloves and protect your arms. Dry ice can cause skin burns due to its extremely low temperature. Insulated gloves will protect your skin from frostbite when handling dry ice. Always handle dry ice in small amounts. Additionally, wearing long sleeves will help protect your arms when working with dry ice.

Store dry ice in an insulated container. A cooler made of thick foam material is ideal for long-term storage of dry ice. You can use a standard cooler, such as the type used for chilling beverages.

Crumple some paper and add it to the container. Fill the remaining space in the container with crumpled paper. This helps slow down the sublimation process by reducing empty space inside the container.

Limit opening the container lid. The more frequently you open the container, the more warm air enters. Warm air accelerates the sublimation process, causing the dry ice to evaporate faster.

Place the cooler in a cool location. If it's cold outside, you can leave the cooler outdoors. If it's hot, store the cooler in a cool indoor area. In general, keep the external temperature as low as possible to slow down the sublimation of dry ice.

Be cautious of burns. If the skin is mildly burned and turns red, the burn will heal on its own. However, if dry ice causes blistering or peeling, you should seek medical attention.

Store dry ice in a well-ventilated area. The CO2 gas from dry ice can be harmful to humans in enclosed spaces. Therefore, ensure the storage area is properly ventilated. Otherwise, both people and animals may suffocate.

• Note that the interior of a closed car is often poorly ventilated, especially when the air conditioning is off. Thus, avoid placing dry ice in a parked and closed car. While driving, keep windows open or turn on the AC to allow air circulation. Additionally, do not place dry ice near you while driving.

Avoid using airtight containers. Dry ice sublimates instead of melting, releasing CO2 gas. As CO2 turns into gas, it needs space to escape. If you use a sealed container, the gas cannot escape, and in some cases, excessive gas buildup may cause an explosion.

Do not store dry ice in a freezer. Freezers are airtight and can cause dry ice to explode. Moreover, placing dry ice in a freezer or regular refrigerator can damage the system, as temperature sensors are not designed to handle the extreme cold of dry ice.

Wear goggles and a protective mask when cutting dry ice. If you need to cut a block of dry ice, always wear goggles and a protective mask to shield your eyes. Otherwise, small ice fragments could fly into your eyes and cause burns.

Avoid low-lying areas. CO2 gas tends to settle because it is heavier than oxygen. As a result, CO2 accumulates in low areas. Avoid bending down or staying in such zones for extended periods.

Be mindful of the surface where you place dry ice. The extreme cold of dry ice can damage many surfaces. For instance, it can crack tiles or damage countertops if placed directly on them.

Dispose of dry ice properly. The best way to dispose of leftover dry ice is to let it sublimate naturally. Ensure the area is well-ventilated during this process.

• Avoid placing dry ice in sinks, toilets, or trash bins to prevent damage. Similarly, do not leave it in places where others might accidentally pick it up or touch it, as they may not realize it is dry ice and could get burned.
