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 the oxygen away from a fire?
You can take away oxygen from a fire by covering it with a fire blanket, using a fire extinguisher that works by smothering the flames, or by cutting off the oxygen supply by closing off vents or doors. This reduces the ability of the fire to sustain itself and causes it to die out.
How do you take oxygen away from fire?
you put a cup over it lol
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.
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 part of the triangle does a fire blanket take away when it puts the fire out?
A fire blanket removes the oxygen supply from the fire when it is placed over it, suffocating the flames and extinguishing the fire.
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 is taken away if you smother a fire with a fire blanket?
When you smother a fire with a fire blanket, you remove oxygen, one of the elements needed for fire to burn. By restricting the supply of oxygen, the fire is deprived of the required component to sustain combustion, leading to its suppression.
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.
