What is Dry Ice, and Why Can It Be Dangerous?
Dry ice is the solid form of carbon dioxide (CO₂). Instead of melting into a liquid, it “sublimates”, meaning it turns
directly from a solid into a gas. It is extremely cold, about −78.5°C (−109.3°F).
Key risks include:
- Frostbite-like injuries (dry ice burns) from direct skin contact
- CO₂ buildup in poorly ventilated spaces, which can reduce oxygen and cause breathing issues
- Pressure buildup and possible explosion if stored in sealed containers
- Oral and eye injuries if pieces contact your mouth or eyes
Dry Ice Safety Basics: Do’s and Don’ts
Simple precautions go a long way.
Do:
- Use protective gear: Wear insulated, waterproof gloves or tongs, eye protection, and long sleeves.
- Work in fresh air: Use dry ice in well-ventilated areas; open windows or work outdoors when possible.
- Store in a vented cooler: Choose a cooler or container that is not airtight so CO₂ can safely vent.
- Keep out of reach: Store away from children and pets.
- Use food-grade dry ice for food-related uses.
Don’t:
- Don’t touch with bare skin: Even a brief touch can cause an immediate cold burn.
- Don’t store in airtight containers: Gas can build up and burst the container.
- Don’t use in small, closed rooms or cars without ventilation: CO₂ can accumulate and displace oxygen.
- Don’t put dry ice directly into someone’s mouth or swallow pieces: This can burn the mouth, throat, and stomach.
- Don’t dispose of in sinks, toilets, trash chutes, or closed spaces: Let it evaporate in a safe, ventilated area away from
people and pets.
Dry Ice Burns: What They Are and What to Do?
Direct contact with dry ice can freeze skin and underlying tissues, similar to frostbite. The injury may not feel painful at
first because cold can numb the area quickly.
Signs and Symptoms
Here are some of the signs and symptoms:
- Numbness, tingling, or stinging
- Skin that looks pale, hard, waxy, or white/grayish-yellow
- Increasing pain or swelling as the skin rewarms
- Severe cases may lead to blisters or deep tissue damage
First Aid for Dry Ice Burns (Frostbite-Type Injury)
Here are some of the tips for first aid for dry ice burns:
- Get to a warmer area and remove wet or tight clothing or jewellery near the injured area.
- Rewarm gently: Immerse the area in lukewarm water (not hot) for 15–30 minutes. Do not use direct heat (heating pads,
fireplaces, stoves). - Protect the skin: Loosely cover with a clean, dry cloth. Do not rub, massage, or use snow/ice on the area.
- Avoid refreezing: Once rewarmed, keep the area warm and protected.
- Pain control: Over-the-counter pain relievers may help if appropriate for you. Follow label instructions.
When to Seek Medical Care?
Here are the symptoms that suggest that you should seek medical care:
- Moderate to severe burns, blisters, or persistent numbness
- Burns on the face, eyes, hands, feet, or genitals
- Signs of infection (worsening redness, warmth, pus, fever)
- If you’re unsure how severe the injury is
In case of eye exposure: Rinse with clean, lukewarm water for at least 15 minutes and seek urgent medical care.
Handling Dry Ice: Storage, Transport, and Use
Safe handling dry ice is essential whether you’re moving groceries, creating fog effects, or cooling items during travel.
Storage Tips
Here are some of the storage tips:
- Keep in a sturdy, insulated but non-airtight container. A lid should fit loosely to allow venting.
- Place the container in a cool, ventilated location away from sleeping areas.
- Keep separate from the reach of children and pets.
Transport and Cars
Here are some of the ways to transport dry ice:
- Transport in a well-ventilated vehicle compartment. Avoid tightly sealed interiors.
- Crack windows open, especially during longer trips.
- Do not store dry ice in a car trunk for extended periods without ventilation.
- Move the container carefully using gloves or tongs.
CO₂ Exposure Risks and Ventilation
As dry ice sublimates, it releases carbon dioxide gas. CO₂ is heavier than air and can accumulate in low-lying or poorly
ventilated spaces, pushing out oxygen.
Symptoms of Too Much CO₂ (Oxygen Displacement)
Here are some of the symptoms:
- Headache, dizziness, drowsiness
- Rapid breathing or shortness of breath
- Confusion or fainting
- In severe cases, loss of consciousness
Important notes:
- CO₂ is not carbon monoxide (CO). CO₂ does not bind to blood like CO does, but high CO₂ can still be dangerous
because it reduces the amount of oxygen you can breathe. - Workplace guidelines from occupational health agencies set exposure limits for CO₂ to help prevent illness. These limits underscore why ventilation is important when using dry ice.
How to Reduce Risk?
Here are ways to reduce risks:
- Use dry ice outdoors or in rooms with open windows and good airflow.
- Avoid using it in small, enclosed spaces (closets, bathrooms, walk-in coolers) without ventilation.
- Never sleep in a room with dry ice sublimating nearby.
- Consider a CO₂ monitor in work settings or where larger amounts are used.
If someone has trouble breathing, a severe headache, confusion, or faints, move them to fresh air immediately and call
emergency services.
Who Is at Higher Risk?
Here are individuals who are at higher risk:
- Children and pets: More likely to touch or swallow dry ice and are more vulnerable to breathing changes.
- People with lung or heart disease: May be more sensitive to low oxygen environments.
- Pregnant people: Low oxygen environments can be dangerous; take extra care with ventilation.
- Older adults and anyone with limited mobility: May not be able to leave an area quickly if CO2 builds up.
- People working with larger quantities: Caterers, lab workers, or shippers should follow workplace safety protocols.
Practical Checklists You Can Use Today
Here are some of the practical checklists that can be used:
1. Before you start
- Plan for ventilation (open windows/doors or work outdoors).
- Have insulated gloves, tongs, and eye protection ready.
- Choose a non-airtight container.
2. While using dry ice
- Keep handling time brief and use tools to move pieces.
- Supervise children and pets closely; keep a safe distance.
- Watch for early signs of CO₂ buildup: headaches, dizziness, or unusual drowsiness.
3. After you’re done
- Let leftover dry ice evaporate in a safe, ventilated area away from people and animals.
- Do not pour or place dry ice in drains, toilets, or trash compactors.
- Wash hands after removing gloves and clean any surfaces where condensation formed.
4. Safe Disposal
- Leave the remaining dry ice in its container in a well-ventilated area, out of reach of children and pets, until it
completely evaporates. - Keep the container lid ajar to prevent pressure buildup.
Never dispose of dry ice in sinks, toilets, garbage disposals, or sealed trash cans.
When to Call for Help?
Here are some of the signs and symptoms which indicate getting professional help:
- Significant burn, blistering, or any eye injury: Seek medical care promptly.
- Breathing difficulty, fainting, severe headache, or confusion.
- If you’re unsure, get expert guidance immediately.
Conclusion
With the right precautions, ventilation, protective gear, and smart storage, dry ice can be used safely at home and at events. Keep these tips handy, supervise kids and pets, and act quickly if there’s a burn or breathing problem.

Frequently Asked Questions
Q1. Is dry ice toxic?
Dry ice is solid carbon dioxide. It isn’t “toxic” in small amounts, but as it turns to gas, it can reduce oxygen in the air. In poorly ventilated areas, this can be dangerous. Never swallow dry ice.
Q2. Can I put dry ice in drinks?
Do not put dry ice pieces directly into a drink that someone might swallow. Use food-grade dry ice for fog effects near drinks, and ensure all pieces have completely evaporated before anyone sips from a container that held dry ice.
Q3. How long does dry ice last?
It depends on the amount and how well it’s insulated—often from several hours to about a day in a typical cooler. Plan to buy it close to when you need it, and store it in a vented container.
Q4. What should I do if I touch dry ice and get a burn?
Treat it like frostbite. Warm the area gently with lukewarm water (not hot), avoid rubbing, protect the skin with a clean, dry cloth, and seek medical care if there is blistering, severe pain, or numbness.
Q5. How can I use dry ice at home safely?
Follow dry ice safety basics: Wear insulated gloves and eye protection, keep good ventilation, store in a non-airtight cooler, supervise children and pets, and never use it in small enclosed spaces.
