What danger is associated with an oxygen leak?

An oxygen leak poses a significant danger primarily because combustible materials can ignite more rapidly in an oxygen-rich environment. When the concentration of oxygen in the air increases, as it would occur in the event of a leak, the flammability of materials also increases substantially. This means that common materials that would not normally pose a threat in ambient air could catch fire more easily and burn more intensely, leading to a higher risk of fire and explosion in a confined space, such as an aircraft.

Other factors related to aviation safety, such as engine failure, visibility issues, or communication problems, are not directly tied to the hazards posed by an oxygen leak. While these issues are critical in flight operations, they are distinct from the chemical and physical risks associated with increased oxygen levels in the environment. Therefore, recognizing the heightened flammability caused by oxygen saturation is crucial for maintaining safety protocols and responding effectively to any leaks that may occur.
