When should emergency oxygen systems be checked for pressure levels?

The correct response indicates that emergency oxygen systems should be checked for pressure levels before each use. This practice is essential for ensuring the safety and effectiveness of the oxygen system in emergency situations. By verifying the pressure levels prior to use, operators can confirm that the system is fully charged and operational, thereby preventing potential failures that could occur during an emergency when immediate access to oxygen is critical.

Being diligent about checking the pressure levels each time prior to engaging the system minimizes risks and ensures that the equipment is in proper working condition. Relying on monthly or weekly checks may lead to situations where the oxygen system is not adequately pressurized at the time of need, which could compromise the safety of those relying on it. Assessing the system before use enables prompt identification of any issues that may affect the oxygen supply, allowing for timely corrective actions.
