How can the contact of oxygen with a person whose clothes catch fire be prevented by pressing him against a wall or the ground?

Oxygen is essential for combustion. And when we cover a person with a blanket, or push him against a wall of ground (the side of the person pressed against the wall will not get oxygen), we are essentially breaking contact between the burning part and air. This will cut of the oxygen supply and stop the object from burning.  

Hope this information will clear your doubts about the topic.
