Doesn't make sense?
Drain all of the fuel out of your car petrol tank then drop a match down the filler cap and providing that there is also a bit of oxygen available, you will soon see why it makes sense.
In some cases, a container or casing which has a mixture of oxygen and an inflammable vapour can be more dangerous than a container filled to the brim with an inflammable liquid with no space for air/oxygen.
Do a quick search on Google and you will find plenty of example such as this one:
