Liquid gasoline does not readily explode. It must first be vaporized and mixed with sufficient amounts of oxygen.
However it will burn proportional to the amount of oxygen reaching the flame.
Not saying that it is not dangerous... only that danger and caution should be in proper perspective.
You can throw a burning cigarette into a bucket of gasoline and the liquid gasoline will extinguish the burning ash... the same as water would.
Don't suggest you try it... just take my word for it. An open flame however will set the gasoline in the bucket afire.... but it will not explode because oxygen can only reach the limited surface of the liguid.
