Although liquid oxygen gas is not combustible, but it can give other flammable and explosive gases strongly fueled by combustion, liquid oxygen gas has two types of combustion reactions, which all depend on the mixing ratio of oxygen and fuel and ignition situation.
 
One is the fuel and liquid oxygen in the mix without fire, but this mixture when ignition or mechanical impact can occur when the explosion; the other liquid oxygen and fuel in contact with each other before or when the combustion has begun, fire or combustion and accompanied by repeated explosions.
 
How to properly use and safely store liquid oxygen gas
Liquid oxygen storage tank Liquid oxygen storage tank
Avoid contact with organic and combustible materials. It is recommended to keep the liquid oxygen bottle outside. Smoke and fire are strictly prohibited. Transport must be labeled as "non-flammable, oxidizer", limited transport of compressed oxygen, air and rail transport of liquid oxygen is strictly prohibited.

Keep away from heat and fire sources; avoid direct sunlight. Connected valves, pipes, instruments, etc. are strictly prohibited to grease. Keep the container airtight. Wear protective clothing and gloves when filling liquid oxygen.

Worker protection measures, protective equipment: It is recommended that emergency handlers wear self-contained breathing apparatus and general operating overalls. Avoid contact with combustible or flammable materials. Cut off the source of the leak if possible.
