Where should the emergency oxygen supply connection be placed when multiple buildings are served from a single cryogenic liquid oxygen source?

The emergency oxygen supply connection should be placed at each building served by a single cryogenic liquid oxygen source to ensure that all facilities have immediate access to oxygen in the event of an emergency. This placement is crucial because it allows for rapid response in situations where a building may experience an oxygen deficiency, such as a medical emergency or system failure. By having connections at each individual building, the risks associated with delays in accessing oxygen are minimized, ensuring the safety and health of patients and staff across all facilities.

Having connections exclusively in one building or at the nearest or largest building could create significant problems in an emergency scenario, where time is of the essence, and immediate availability of oxygen is critical. Therefore, distributing the connections across all buildings guarantees that all areas are equally prepared and reduces the chances of any building being left without the means to provide necessary oxygen during urgent situations.
