Any substance that burns in air is likely to burn faster in pure oxygen, if all other conditions are equal.
Technically, no, but there still is a fire hazard. Oxygen itself is not flammable. It does, however support the burning of flammable substances; this is how fires burn normally. Oxygen tanks provide pure oxygen (nearly 5 times the natural concentration), which means that any flammable substances in contact with it will be more easily ignited and will burn hotter and faster if a fire starts.
Oxygen is used up.
Oxygen.
Oxygen is the gas that is used up when substances burn. The reaction between the substance and oxygen produces heat and light energy.
Yes, oxygen itself does not burn but it feeds the combustion of other materials, like paper, making fires burn more intensely. Oxygen speeds up the chemical reactions involved in fire, causing materials such as paper to burn faster in its presence.
When they burn through oxygen faster than their cells can get it, ie sprinting
more space for air (oxygen)
No, oxygen itself is not flammable. However, it supports combustion, which means it helps other substances burn. Oxygen-rich environments can make fires burn hotter and more rapidly.
Hydrogen is a colorless gas that burns with oxygen. If substances will burn in air, those same substance will burn better in oxygen.

Steel wool burns faster in pure oxygen compared to air. This is because pure oxygen provides a more efficient environment for combustion, allowing the steel wool to ignite and burn more rapidly. In air, the presence of other gases dilutes the oxygen, slowing down the burning process.
In general, no, it accelerates / increases fires. If the fire is based on methane, say, and the oxygen displaces all the methane, then the fire will go out. If the oxygen is passed through / across the fire at something approaching supersonic speed, if the fire doesn't go out, it *will* go somewhere else.
