Could that really be it? Can dry ice used to keep ice cream from melting be fatal for someone?

What’s the Harm With Dry Ice?

Dry ice is a solid form of carbon dioxide gas, the same gas that we exhale from our bodies when we breathe.


Normal air contains 78% nitrogen, 21% oxygen and only 0.035% carbon dioxide. If the carbon dioxide in the air exceeds 0.5% then it can be dangerous.

In the normal environment, that is in room temperature, dry ice changes directly from the solid state to gas, a process known as sublimation.

So if you have put dry ice in a place where there is no better ventilation, it is possible that the concentration of carbon dioxide will increase so much that it can prove dangerous for you. So issues like rapid breathing, headache, confusion, asphyxia or even death.
