Is Dry Ice Toxic to Humans

It is very dangerous to use dry ice in a walk-in freezer, cooler, closed truck bed, or other small space with poor ventilation. A large amount of dry ice in a walk-in cooler or freezer can produce a great deal of carbon dioxide, which can possibly be fatal to someone entering that space.

Is it safe to be in a room with dry ice?

Dry ice gives off CO2 (carbon dioxide) gas into the air, which can be dangerous within a confined space, such as a car, van, or room. If dry ice has been present in a confined space for more than 10 minutes, open the doors and windows before entering the space.

Can dry ice give you carbon monoxide poisoning?

Cases of poisoning with dry ice occur worldwide, and have been reported in countries such as Germany, Japan, Thailand, Switzerland and the United States.
