Dry ice is a big deal in the shipping world. It's a fascinating substance that emits fog or smoke. It gets its appearance since it's actually the solid form of carbon dioxide.
When you buy dry ice, there are always warning signs advising you to use gloves. That's because it's extremely cold. In fact, it's so cold that it can cause skin blisters and is highly dangerous to handle bare-handed. In this guide, we'll explore just how cold dry ice can get.
How Cold Is Dry Ice?

Dry ice has a surface temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). For comparison, regular ice (frozen water) has a temperature of 0 degrees Celsius (32 degrees Fahrenheit).
How Is Dry Ice Made?
Dry ice is frozen carbon dioxide gas.
The process begins by capturing carbon dioxide gas from industrial sources, such as ammonia, ethanol, and hydrogen plants, where it is a byproduct. The gas is then pressurized and cooled until it liquefies. Once in liquid form, the carbon dioxide is allowed to expand rapidly which causes it to freeze into a solid state. This solid is then collected and compressed into dry ice pellets, blocks, or slices. Throughout this process, the temperature is kept extremely low to maintain its solid state.
Hazards of Handling Dry Ice

- Since dry ice is extremely cold, it can cause severe frostbite or skin burns if touched without thick, insulated gloves.
- As mentioned before, carbon dioxide gas makes dry ice. During the sublimation process where solid dry ice turns into gas, it can cause difficulty in breathing, dizziness, or even unconsciousness, especially in confined spaces with poor ventilation.
- It can also cause explosions. If dry ice is stored in a tightly sealed container, the sublimation process can cause a buildup of pressure. This pressure can eventually cause the container to burst.
- If it's ingested, it can cause severe internal injuries due to its extreme cold and rapid sublimation.
- It can be used to create artificial carbon dioxide snow.
- It can be used for dry ice blast cleaning which is an industrial cleaning method that uses high-speed dry ice blasting machines to remove contaminants from surfaces.
How to Ensure Safety
- Always wear thick, insulated gloves to protect your hands from frostbite and burns.
- Use safety goggles to protect your eyes from any chips or fragments that might break off.
- Always use it in open or well-ventilated spaces to prevent carbon dioxide buildup. Avoid using it in small, enclosed spaces.
- Store dry ice in insulated containers. Do not store it in airtight containers, as the gas buildup can cause the container to burst.
- Never eat or swallow dry ice. Keep it out of reach of children and pets to prevent accidental ingestion.
What Can You Use Dry Ice For?

- You can use it to keep perishable goods, such as food and medical supplies, frozen during shipping or power outages.
- It can be used in theatrical productions, movies, and Halloween decorations due to the fog-like effect.
- It can be used in laboratories for experiments that require low temperatures.
- It can be used to carbonate beverages.
- It can be used in the medical field to preserve biological samples and organs.
What's the Difference Between Liquid Nitrogen and Dry Ice?
Liquid nitrogen is the liquid form of nitrogen. It has a very low temperature of -320.4 degrees Fahrenheit (-196 degrees Celsius). It is a colorless, odorless liquid that boils at room temperature, turning into nitrogen gas.
Dry ice, on the other hand, is the solid form of carbon dioxide and has a temperature of -109.3 degrees Fahrenheit (-78.5 degrees Celsius). Unlike liquid nitrogen, dry ice sublimates directly from a solid to a gas without becoming a liquid.
Summary
Dry ice is an incredibly useful substance due to its extremely low temperature. It is much colder than regular ice and has unique properties that make it valuable in various fields. However, it must be handled with care due to its potential hazards.
