Effective Methods for Long-Term Dry Ice Storage

Dry ice is a solid form of carbon dioxide that is commonly used in transportation and storage of perishable goods. It has a temperature of -109.3°F (-78.5°C) and can be dangerous when not handled properly, as it sublimates (turns into gas) rapidly.

In this blog post, we will be discussing the best practices for storing dry ice long term to ensure safety and quality maintenance.

Storing Dry Ice Long Term: Best Practices

1. Choose appropriate containers

When storing dry ice long term, it’s important to choose the right container. The container should be well-insulated and able to withstand extreme temperatures without breaking or cracking.

It’s recommended that you use an insulated cooler made from materials such as Styrofoam or plastic. These materials provide good insulation properties and help maintain the low temperature inside the container.

Make sure that there are no holes or cracks in the lid or sides of your container, as these could allow warm air to enter which would cause your dry ice to sublimate much faster.

2. Pack effectively

Once you’ve chosen your insulated container, it’s time to pack it properly with your dry ice.

Place a layer of newspaper at the bottom of your cooler before adding any dry ice blocks or pellets on top. This helps protect against potential leaks that may occur during transport.

Next, place another layer of newspaper on top of the first layer followed by more dry ice until full up but leaving some space at least 15% room for expansion when frozen solid so they won’t explode upon freezing due to increased pressure inside containing vessel caused by expansion during freezing process

Finally close tightly sealing off all possible openings like zips/locks/etc using duct tape if required around them too

Ensure there are no air pockets between each layer of dry ice as these can cause the temperature inside your container to fluctuate, which will increase the rate at which your dry ice sublimates.

3. Store in a cool and dry place

Dry ice should always be stored in a cool and dry place, away from any heat sources or direct sunlight. This will help maintain its low temperature and slow down the sublimation process.

If possible, store your insulated cooler in a cold room such as a cellar or basement. If you don’t have access to one of these spaces, consider placing it in an air-conditioned room instead.

Remember that dry ice is extremely cold – if you’re storing it indoors, ensure that there is sufficient ventilation to avoid build-up of carbon dioxide gas which can pose serious health hazards when breathed in by humans

4. Monitor Temperature Regularly

It’s important to monitor the temperature inside your container regularly using an infrared thermometer gun or other appropriate device. This ensures that the correct temperatures are being maintained for optimal storage conditions.

You should check on them once every 24 hours (or more frequently if necessary) to make sure they haven’t warmed up too much since last checked.

To keep things even cooler for longer try doubling qty of Dry Ice blocks/pellets so you get double amount cooling power where needed like camping trips etc


Storing dry ice long term requires proper handling and storage techniques to ensure safety and quality maintenance. Using appropriate containers, packing effectively with newspaper layers between each level helps prevent leaks caused during transport; indoor areas like cellars & basements offers best places while monitoring temps regularly enables optimization regarding ideal storage conditions achieved through maintaining low temp levels throughout period set aside for use without compromising quality standards required overall success.Expectancy is essential given importance involved because improper handling may result accidents causing harm either directly indirectly people around us!
