Frequently Asked Questions
What exactly is Dry Ice?
Dry ice is solid carbon dioxide (CO₂). Unlike regular ice, which is made from water, dry ice sublimates directly from a solid to a gas at -78.5 °C (-109.3 °F).
How cold is dry ice?
Dry ice is extremely cold, with a surface temperature of -109.3°F (-78.5°C).
What are some common uses for dry ice?
Common uses for dry ice include shipping frozen food, medical and pharmaceutical transport, camping coolers, special-effects fog for events, industrial dry ice blasting for cleaning, pest control in burrows, and science demonstrations.
What important safety info should I know about dry ice?
- Dry Ice is Extremely Cold: Dry ice is approximately -109.3°F (-78.5°C) and can cause severe frostbite or burns upon contact with skin.
- Always Use Protection: Handle with insulated gloves or appropriate tools. Do not touch dry ice with bare hands.
- Do Not Ingest: Dry ice should never be eaten or placed directly in the mouth.
- Keep Away from Children & Pets: Store securely and supervise at all times.
Do I need special equipment to handle dry ice?
- Gloves: Always wear insulated gloves to prevent frostbite, as dry ice can cause skin burns.
- Eye Protection: Safety goggles are recommended to protect your eyes from splashes or small pieces.
- Ventilation: Use dry ice in well-ventilated areas. It sublimates into carbon dioxide gas, which can displace oxygen in confined spaces.
- Storage: Keep dry ice in a cooler or an insulated container, but never in a sealed container as the pressure can build up and cause it to explode.
- Avoid Direct Contact: Try not to handle dry ice directly; use tongs or other tools if possible.
Following these precautions will help you handle dry ice safely!
Does dry ice leave water when it melts?
No. Dry ice does not melt into liquid. It turns directly into carbon dioxide gas.
How far in advance should I buy dry ice?
Because dry ice evaporates over time, it is best to purchase it close to when you plan to use it.
Do you offer dry ice for shipping frozen food or medical supplies?
Yes, dry ice is commonly used for cold chain shipping to keep products frozen during transport.
How can dry ice be used to fix dents in automobiles?
Dry ice can sometimes be used to help remove small dents from metal panels on a car by rapidly cooling the metal, which causes it to contract. When the metal contracts and then warms back up, the change in temperature can sometimes cause the dent to pop back into its original shape.
How long can I store dry ice?
Dry ice can last for about 24 to 48 hours if stored properly in an insulated container. However, it will sublimate (turn from solid to gas) at a rate of about 5 to 10 pounds every 24 hours, depending on the insulation.
What type of dry ice do I need?
- For dry ice blasting, you typically need dry ice rice 3mm, which is easier to use and provides optimal performance for the blasting process. Ensure it's of good quality to prevent clogs and inefficiencies.
- For refrigeration and freezing you it is most common to use 16mm pellets.
How much dry ice do I need?
You will need 5 to 10 pounds for every 24 hours, depending on the insulation.
How should I store my dry ice?
- Use in Well-Ventilated Areas
Only: As dry ice sublimates, it releases carbon dioxide gas, which can displace oxygen in enclosed spaces. - Do Not Store in Airtight
Containers: Pressure buildup from gas expansion can cause containers to rupture or explode. - Do Not Store in
Refrigerators/Freezers: Standard units are not designed for dry ice and may be damaged or fail.
How should I transport dry ice?
- Transport dry ice in a well-ventilated vehicle
- Do not leave dry ice in a sealed car or confined space for extended periods
- Keep windows slightly open when transporting larger quantities
