How often should emergency oxygen systems be checked for functionality?

Emergency oxygen systems should be checked for functionality before use to ensure they are operational and ready to assist in case of an emergency. This practice is critical because, in emergency situations, timely access to functional oxygen can be life-saving. Regular checks prior to use guarantee that the equipment is in good condition, properly maintained, and capable of delivering the required oxygen flow when needed.

While it is important for facilities to also conduct regular scheduled checks (like weekly or monthly) to ensure ongoing safety and compliance, these checks alone may not be adequate if the system is not evaluated right before an emergency scenario. Thus, checking functionality just prior to its use is the most immediate and practical approach to ensure readiness and effectiveness in critical situations.
