Which type of emergency reserve system can be substituted for the EOSC?

The correct answer is that an in-building emergency reserve system can serve as a substitute for the emergency oxygen supply system (EOSC). An in-building system is designed to provide a reliable source of medical gas within a facility during emergencies, ensuring that patient care can continue uninterrupted. This system is particularly important in healthcare settings where the availability of oxygen is critical for patient survival and treatment.

In-building systems typically consist of tanks and distribution systems that are readily accessible and can be used without delay during a medical emergency. They are strategically located within the building to support rapid access in critical situations, making it a vital component in emergency preparedness.

Other types of systems, such as auxiliary, backup, or micro-bulk, may have specific applications but do not fulfill the same immediate and inherent requirements as an in-building emergency reserve system. An auxiliary system generally functions as an additional support mechanism rather than a direct substitute. Backup systems may involve separate supply chains and might not be integrated into the immediate infrastructure of a medical facility. Micro-bulk systems are designed for onsite gas storage but may not be comparable to the rapid response capability of designated emergency reserve systems like the in-building model.
