What is the potential consequence of failing to maintain cleanliness around oxygen systems?

The potential consequence of failing to maintain cleanliness around oxygen systems is a significant risk of fire or explosion. Oxygen is a highly reactive element, and its presence can dramatically increase the flammability of materials that may not normally burn in air. Any contaminants, such as oils, greases, or other flammable substances, can ignite more easily in the presence of pure oxygen, leading to hazardous situations.

Proper cleanliness prevents the accumulation of these contaminants and ensures safe operation of the oxygen system. By adhering to stringent cleanliness protocols, the risk of accidental ignition and subsequent fire or explosion can be substantially minimized, ultimately ensuring the safety of both the aircraft and its occupants.

The other options suggest outcomes that do not align with the realities of oxygen systems. Improved system efficiency or increased oxygen supply might seem beneficial, but they are irrelevant if safety is compromised. Similarly, the idea that there would be no impact on performance is misleading, as the cleanliness of oxygen systems is crucial for preventing dangerous incidents.
