#dryicesafety

Most people treat dry ice like regular ice. It is not.

At −78.5°C, this stuff is three times colder than anything in your freezer. Touch it with bare hands and you will have frostbite before you realise what happened. Seal it in an airtight container and the CO₂ buildup will do the rest.

Four rules that will save you a trip to the hospital:

Wear gloves every single time. No exceptions. Use containers designed for dry ice, not whatever is in the cupboard. Keep it somewhere ventilated. CO₂ displaces oxygen in enclosed spaces. Never, ever seal it airtight.

Dry ice is an incredible material when you respect what it actually is. Used right, it keeps pharmaceuticals stable across long hauls, preserves seafood on the water, and powers industrial cleaning without a drop of moisture left behind.

Handle responsibly. That is not a suggestion.
