Carbon Dioxide CO2 extinguishes fire by diluting the oxygen content of the space to a point where it will not support combustion.

Reducing the oxygen content from the normal 21 per cent in airto 15 per cent will extinguish most fires. For some materials the oxygen content must be reduced below 15 per cent, and in some cases its concentration needs to go down to as low as six percent
of the volume.
