Can dry ice fatal?

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.

What happens if you mix dry ice with water?

When dry ice is added to warm water a dense white fog is immediately generated. The white fog is an aerosol of tiny water droplets just like fog created naturally. What's happening is that the very cold dry ice is subliming from solid to the gaseous phase and bubbling through the water.
