Fire needs oxygen (O2), and when you pour CO2 on the flame, it replaces the oxygen, and the combustion in the flame can no longer happen.

Kind of the same principle of why you can't breath underwater. You nor a flame can breath CO2 or water.

It contains no liquid, therefore will not conduct electricity. Using water or foam would conduct electricity with the possibility of death. Any other inert gas would do.

CO2 puts out a fire by Oxygen exclusion. Fire requires oxygen to burn and when CO2 is used to extinguish fire, it displaces the oxygen.
