It is sometimes possible to tightly close off the fire. For example, if the material in a pan on a stove ignites, the very best response is to slip the lid onto the pan, quickly starving the fire of oxygen. It would not be a good idea to throw anything like liquid into the pan.
You can also remove oxygen from a fire by putting something on the fuel that keeps oxygen away. This is what happens when you use a Halon gas fire extinguishing system. When you put water on a fire, one of the two things water does is to prevent oxygen from getting to the fuel.

Why do fire men use sand to put a fire out?
because it takes away the oxygen which fuels a fire.
Why does a fire go out when you pour cold water on it?
Fire needs Oxygen gas to burn. The water pushes the Oxygen gas away from the fire, preventing it from burning.
How does a blanket help to extinguish a fire?
A fire requires oxygen in order to continue to burn. Placing a blanket over the fire robs it of the necessary oxygen, and thus helps to extinguish the flame.
How do you take oxygen away from fire?
you put a cup over it lol
How does pouring dry sand over the fire blows it?
It takes the oxygen away from the fire, which the fire needs, thus snuffing it out.
What factors affect fire?
The 3 pillars of fire are heat, oxygen and fuel. Taken away one of those and the fire will dies out.
How do you take the oxygen away from a fire?
Flood it with another gas, such as CO2 or nitrogen.
Why does water prevent paper from burning?
Fire needs oxygen to burn. If you take away the oxygen there is nothing feeding the fire so it cannot carry on burning. Water has too little oxygen in it to feed the fire, and so it snuffs the flame, putting it out.
What helps start fire?
It is part of the fire triangle. The three things you need are: Heat, Oxygen and Fuel. if you took away one of theese things then a fire would not create.
Why are carbon dioxide used as extinguisher?
Carbon dioxide is used because it takes away the heat from the fire. Carbon dioxide is very cold and also displaces the oxygen. Heat, oxygen and fuel are part of a "fire triangle" take any of those elements away and the fire will be extinguished.
What do fire extinguishers remove from the fire triangle?
It depends upon what kind of extinguisher it is. Water, for example, removes the heat from a fire by turning into steam and by removing available air/oxygen from the flames. Other extinguishers remove the oxygen from the fire or change the chemical reaction to stop the fire from converting the fuel to a flammable substance with the available heat.
What properties does a slipper have to control fire?
You can normally control a *very small* fire by hitting it with your slipper because it will be starved of oxygen and momentarily cooled. Fire needs 3 things: Fuel, oxygen and heat. By hitting it with your slipper, you will take away some of it's heat, and you will starve it of oxygen.
