It is crucial for sustaining life, as it is used during respiration. However, high concentrations of oxygen create an enriched environment that can accelerate combustion. Materials that may not burn in normal air may burn vigorously in an oxygen-rich environment, with a simple spark being enough to potentially cause fires.
In many industrial processes, oxygen levels can be displaced by other gases, so it’s important to monitor oxygen levels and evacuate if oxygen levels fall below 19.5% by volume.
