Is oxygen needed for a combustion reaction to take place?

What is The action of removing air or oxygen to put out a fire?
The action of removing air or oxygen to put out a fire is called smothering. By depriving the fire of oxygen, it is unable to continue burning and will eventually extinguish. This can be done using fire extinguishers, blankets, or other methods to block the air supply to the fire.
