If it can form a 'blanket' over the fire then it stops the oxygen getting there. But often it simply cools the burning material down so that it stops burning.

What happens when you remove oxygen from a wood fire?
That is, what they already do. No kind of fire can burn without oxygen!
Why does fire stop under water?
Fire needs oxygen from the air just like we do. When water gets poured on it, it suffocates and goes out.
How can you stop something burning?
extinguisherBy removing the oxygen from the fire by use of fire extinguishers, fire blankets , hose pipe if available even buckets of water DO NOT USE WATER ON FUELS E.G. COOKING OIL, PETROL ETC. Larger fires must be put out by the fire service as fire extinguishers etc are designed for small fires. A very small fire e.g. a bit of paper can even be stamped out if your wearing shoesThrow water on it
Why does hot water puts off the fire faster than cold water?
Triangle of fire is Heat, Fuel and Oxygen. Cold water might put off heat more than hot water but hot water is ready to evaporate to steam and block off oxygen from reaching the fuel. On fire fighting, reason to aim water at the base of fire is to allow steam blanket to form and block off the oxygen and thus put off the fire.
What puts out a fire?
Sand /water <><><> Anything that will cool the fire below kindling point, or exclude oxygen from the fire.
What happens when you remove fuel and oxygen from fire?
If you remove fuel, oxygen, or both from a fire, the fire goes out.
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.

Why does water usually put out fire?
Water stops oxygen from getting to the flame, and oxygen is the fire's food.
Why does fire not burn in water?
Fire feeds on oxygen, and water does not have much of it.
Why does fire stop if water is poured on it?
Fire needs oxygen to continue burning. Water cuts of the supply of oxygen and hence the fire stops.
Why does fire stop under water?

Why does water put out fires?
The fire triangle is fuel (something that will burn), oxygen and heat. If you take away any of the three the fire will go out. Water reduces the temperature and causes the fire to die out. A note here: Water is used on class "A" fires only. A class "A" fire is anything that will leave an ash when burned such as paper, wood or cloth. If you were to try to use water on a class "B" fire (a liquid fuel fire) the water will cause the liquid to spread out rather than cool it and make the fire worse. A class"C" fire is anything electrical and while water may put the fire out you run the risk of electrocution if you use water. There is also a class "D" type of fire that includes metals such as magnesium that will burn. If you put water on burning magnesium such as an airplane wheel the magnesium may explode.
How do firefighters use the fire triangle to stop fires?
The fire triangle consists of three components - Heat, Oxygen and Fuel. All three MUST exist together for a source of ignition to start a fire, which in effect is a chemical reaction. If you remove one of these elements, then the reaction can not occur and hence, no fire.
What is the real fire extinguisher?
lack of oxygen OR of flammable material (fuel), but usually lack of heat. Water is used to remove heat from a fire involving ordinary combustibles.
Why do firemen use water?
Firefighters use water to extinguish fires because water absorbs heat from the fire, cools it down, and eventually puts it out. Water can also help to remove oxygen from the fire, which is essential for combustion. Additionally, water can help to prevent the fire from spreading to other areas.
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.
