Regular air in the environment is about 21% oxygen. A fire only needs about 16% oxygen to catch and burn. See http://www.bradford-co-fla.org/scvfd/fire_information.html

How does oxygen distribute fire?
Oxygen does not distribute fire. Fire is a chemical reaction between oxygen and some flammable substance. Fire cannot burn without oxygen, and the more oxygen there is, the hotter and faster a fire will burn. More oxygen also makes it easier for materials to ignite.
What happens when fire mixes with hydrogen?
If there is enough oxygen, the hydrogen will ignite and burn rapidly, possible leading to an explosion.
Why does a fire to burn it needs iginted?
Because there are three things a fire needs to ignite- Fuel (wood petrol etc.), Heat (a match or lighter) and oxygen. Thats why fire cannot burn in space.
Can you ignite a fire with carbon and oxygen?
No, three things are needed the ignite a fire, carbon (fuel), oxygen and heat.
Is pure oxygen explosive?
No. Oxygen itself is not flammable, but it is necessary for fire. Fire is a chemical reaction between oxygen and a flammable substance. Fire is possible on Earth because ordinary air is 21% oxygen. Pure oxygen is considered a fire hazard because higher concentrations of oxygen will make it easier for a fire to ignite and will allow it to burn hotter and faster than normal.
Could oxygen start a fire?
Not on its own. To have a fire you need three ingredients: fuel, oxygen, and heat. Fire is a chemical reaction between oxygen and some flammable fuel. The heat is needed to ignite and sustain the reaction. Our atmosphere is 21% oxygen, which makes fire possible here. Oxygen tanks, which contain pure oxygen, are a fire hazard because higher concentrations of oxygen make it easier for flammable materials to ignite and allow a fire to burn hotter and spread faster.
How oxygen effects fire?
Oxygen is one of three things that must be present for a fire to exist. The three things are:an oxidizer (oxygen is the most common one),fuel (something to burn - that is to combine very rapidly in a chemical reaction with oxygen), anda source of ignition (a spark, heat, etc.)Remove any one of the three and there can be no fire. If you provide more oxygen the fire will burn hotter, or will ignite more easily or at a lower temperature. If you provide more fuel, the fire will burn longer.
How many percent of oxygen level to ignite the fire?
16.3%
Why does flame require air to burn?
fire needs oxygen to burn, because fire is a chemical reaction that needs oxygen. the fire triangle is what fire needs to burn and is this- heat, fuel, and oxygen.
True or false fire will not burn without oxygen?
True, fire must have oxygen to burn.
Can oxygen in a tank combust?
No. Oxygen itself is not flammable. Rather, it supports the combustion of flammable materials. Oxygen tanks do, however present a fire hazard. Normal air is 21% oxygen, while oxygen tanks carry 100% oxygen. A higher concentration of oxygen makes it easier to ignite flammable materials and allows a fire to burn hotter.
Can a fire burn in a room with no oxygen?
No it can't. You need oxygen to burn for it to work.
