Oxygen is not a fuel for fire; it is the oxidizer. You can substitute a different gas for oxygen such as chlorine, fluorine, or dioxygen difluoride. You can also use solid oxidizers such as potassium nitrate or ammonium perchlorate.
Other gases that can support combustion include hydrogen, methane, and carbon monoxide. These gases can act as oxidizers in the absence of oxygen and can sustain a fire by reacting with the fuel in the combustion process.
Sand is better to put out fire than sugar. Sugar is flammable and can actually fuel a fire, while sand is non-flammable and can help smother the flames by cutting off the fire's oxygen supply.
Burning, or combustion, requires three main elements: fuel, oxygen, and heat. The fuel provides the substance to burn, oxygen acts as the oxidizer, and heat initiates and sustains the chemical reaction between the fuel and oxygen. Without any of these elements, burning cannot occur.
Beacause fire needs oxygen to stay lit, and water has oxygen in it.
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.

Titanium burns in nitrogen as well as oxygen. You might get some argument that combustion mean "in oxygen" but I think it is fair to say that lots of things "burn" in something other than oxygen. They undergo chemical reactions while giving off light and heat.Combustion is a process in which some is oxidized in an exothermic reaction. Things can be oxidized by other chemicals than oxygen, such as Cl2 or F2, and that would be considered combustion.Pyrolysis is a thermochemical reaction in which organic matter undergoes decompostion(or combustion in another sense) in the absense of oxygen.This is a clear example of combustion without oxygen.See the Web Links to the left for more information.
There was as much oxygen as there is outside today which meant the fire could spread much easier than without oxygen

No there is no other relay.

Fire requires three things: heat, fuel, and oxygen. If you take one of them away, then the fire will stop. By wrapping a heavy blanket around a burning object, it blocks oxygen in the air from getting to the fire and the fire goes out.
Yes. Chlorine could sustain such a reaction as well.
You get low in a fire more to avoid breathing in smoke, which is toxic, than to get oxygen.
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.
Fire itself does not have a stimulus in the way living organisms do, as it is a chemical reaction rather than a biological entity. It occurs when a combustible material reacts with oxygen at a sufficient temperature, generating heat and light. The stimulus for fire can be considered the heat source that initiates combustion, such as a spark or flame. Once ignited, fire can sustain itself as long as it has fuel and oxygen.
Fire is not considered matter because it is a form of energy rather than a substance with mass and volume. It is a result of a chemical reaction between a fuel and oxygen, and does not have a fixed shape or size like matter does.
