Caution must be exercised with dry ice! Not only will it instantly freeze human flesh, it is also an oxygen displacing compound when it off gases. The higher the humidity the more it will off gas. Allowing it to off gas in a confined living space (without ventilation), it can lead to asphyxiation. In an RV refrigerator use it only in the freezer otherwise it will freeze everything in the fridge.

Good point. More simply stated, "Dry Ice" is really solid, frozen Carbon Dioxide, CO2. It is heavier than air and will fill a closed trailer from the bottom up as it transitions ("melts") from the solid state directly to the gaseous state. (At normal atmospheric pressure, there is no liquid state.)
Your cat or dog might suffocate on the floor while you are fine at the table. Dangerous for workers in pits, etc.
