Despite its frosty appearance, dry ice is dangerously cold to the touch and can lead to serious burns.

Ever been curious about the effects of touching this chilly solid? Here are the frosty details behind a dry ice burn and how it impacts your skin.
What Is Dry Ice?
Dry ice is simply carbon dioxide in its solid state. Unlike the ice cubes that cool your drinks, this special ice has a fascinating property: sublimation. Instead of melting into liquid, it directly transforms into carbon dioxide gas.
Temperature of Dry Ice
As much as we admire dry ice's remarkable qualities, it's important to note that a block of dry ice has an incredibly low surface temperature of -109.3°F (-78.5°C). That's significantly colder than the frozen treats in your freezer.
What Happens During Direct Contact?
Touching dry ice feels much like grabbing a hot pan handle without protection. A quick touch may only leave a slight redness on your skin, but if you hold on for too long, you'll experience the full effect of an ice burn.
These aren't the usual heat-related burns, but injuries caused by intense cold. Dry ice literally freezes your skin cells, leading to damage similar to a heat burn.
The Science Behind Ice Burns
When you come into contact with dry ice, its freezing temperatures cause your blood vessels to constrict, reducing circulation in the affected area. This lack of blood flow can result in severe tissue damage, often resulting in what we recognize as frostbite.
Signs of an ice burn include pale, waxy skin, discomfort, and noticeable changes in skin color.
Safety First: Handling Dry Ice
Always exercise caution when handling dry ice to avoid burns. Wear thick gloves and refrain from direct skin contact.
Remember, it's always wiser to err on the side of caution when interacting with this cold companion!
First Aid for Ice Burns
It's vital to address the burn immediately after it's sustained.
Begin treatment by soaking the affected area in warm water for about 10 minutes. Avoid using hot water, as it can exacerbate the damage to the already injured tissues.
For soothing relief, apply aloe vera and ensure the affected area stays clean to avoid infection. If blisters form or you experience intense pain, it's essential to consult a healthcare professional immediately.
