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.
That is, what they already do. No kind of fire can burn without oxygen!
You can remove heat from a fire by cutting off its oxygen supply, using a fire extinguisher, or dousing it with water. Removing the heat source or covering the fire with a non-flammable material can also help extinguish the fire by reducing heat.
Fire stops under water because water deprives the fire of oxygen, which is essential for combustion. Without oxygen, the chemical reaction that sustains the fire cannot continue, causing the flames to be extinguished.
Boiling water will not remove oxygen from boiler water; it will actually deaerate the water, reducing the dissolved oxygen content. Oxygen removal from boiler water typically relies on mechanical deaeration processes or chemical treatments.
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
If you remove fuel, oxygen, or both from a fire, the fire goes out.
No, boiling water does not remove oxygen from the water.
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.

Water stops oxygen from getting to the flame, and oxygen is the fire's food.

Fire feeds on oxygen, and water does not have much of it.
Fire needs oxygen to continue burning. Water cuts of the supply of oxygen and hence the fire stops.
To extinguish an oxidising flame, you should remove the oxygen source by covering the flame with a non-flammable material like a fire blanket or using a fire extinguisher designed for oxidising fires. Never use water on an oxidising fire as it can make it worse.
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.
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.
