What must be done if an oxygen system has been depleted or moisture detected?

If an oxygen system has been depleted or moisture is detected, purging the system with dry nitrogen or dry air and oxygen is essential. This process is critical because moisture in an oxygen system can lead to ice formation, which may block the flow of oxygen, or it can create a favorable environment for corrosion within the system components. Purging with dry gases serves to remove any residual moisture and ensure that the system is safe and functioning properly.

The use of dry nitrogen or dry air helps displace any moisture and impurities that may have been introduced into the system, effectively restoring the system's purity and safety. Once purging is conducted, it is then appropriate to recharge the system with oxygen, ensuring that it meets operational standards. This procedure is vital in maintaining the integrity of the oxygen system and ensuring safety during use.
