What is the effect of venting aircraft oxygen during a fire?

Explanation:
Oxygen is the main reactant in combustion, so increasing its concentration around a fire directly speeds up how fast the fire grows. Venting aircraft oxygen into a fire adds more oxidizer to the environment, feeding the flames, raising the heat release, and promoting quicker flame spread. The oxygen-rich plume can mix with nearby fuels—like plastics, upholstery, and other cabin or structural materials—making ignition easier and flames more intense. This is not a cooling or suppressive action; it worsens the situation by strengthening the fire. So venting oxygen during a fire accelerates fire growth.
