How much do you know about the fire hazard of liquid oxygen?
Dec 18, 2022
Liquid oxygen is nonflammable, but it can strongly support combustion. The fire hazard is Class B. It is usually not spontaneously combustible when in contact with fuel. If the two liquids come into contact with each other, liquid oxygen will cause the liquid fuel to cool and solidify. The liquid oxygen will cause the liquid fuel to cool and solidify. Mixtures of solidified fuel and liquid oxygen are sensitive to impact and often turn explosive under pressurized conditions.
There are two types of combustion reactions.
One is that fuel and liquid oxygen do not ignite when mixed, but this mixture can detonate when ignited or subjected to mechanical impact.
The other kind of liquid oxygen and the fuel have started to burn before or when they come into contact with each other. Fire or combustion is accompanied by repeated explosions. The intensity of the combustion reaction depends on the performance of the fuel.
