As much as flashback preventers are recommended for oxygen and acetylene tanks, there is no way a flame can burn down a closed line UNLESS there is a combustible mixture in the tank to start with. Backflow of oxygen into the acetylene tank is why you need a flashback preventer.

If you have only acetyelene in the tank, and only oxygen in its tank, if you get a fire in a hose the products of combustion (co2, co h2o) prevent the fire from going far down the line.

A little like dropping matches in a jar to make a lantern when you were a kid.
