What is one of the primary requirements for maintaining operational safety in oxygen systems?

One of the primary requirements for maintaining operational safety in oxygen systems is the frequent checks for leaks and blockages. Oxygen systems are critical in ensuring that adequate oxygen supply is available, especially in high-altitude flying or emergency situations. Regular inspections help identify any potential issues that could lead to a failure in oxygen delivery, which might compromise the safety of the aircraft and its occupants.

Detecting leaks ensures that the system is pressurized appropriately and functioning correctly, while checking for blockages guarantees that oxygen can flow unobstructed to where it is needed. This proactive maintenance is vital for the overall reliability and safety of the oxygen system, making it an essential practice in aviation safety protocols.
