A wooden splint which is only glowing in the 21% Oxygen atmosphere will burst into flame when placed in pure Oxygen gas.
The Apollo I cabin fire was possible because of the 100% Oxygen atmosphere used.
Liquid Oxygen (LOX) must be kept at very low temperatures to remain a liquid. Any pressure build-up do to heat will cause the container to vent pure Oxygen gas.

To test for O2 gas we use a glowing splint. O2 gas will cause the glowing splint to burst into flame. A fire requires a fuel and oxygen, so liquid oxygen would be very dangerous around any spark.

1 gallon of LOX (liquid oxygen) will expand into 673 cubic feet of pure oxygen gas. LOX must be kept at a very low temp to avoid it turning into a gas. It boils at -297 degrees F.
