Which portion of the central supply system is present in the piping system during an inspection?

The operating supply refers to the portion of the central supply system that is actively being used to deliver medical gases to the end points in a healthcare facility, such as patient care areas. During an inspection, it is essential to evaluate the operating supply because it directly affects the functionality and safety of gas delivery to patients. This portion is crucial as it ensures that the necessary medical gases, like oxygen or nitrous oxide, are available and effectively distributed for patient treatment.

Evaluating the operating supply during inspections also helps identify potential issues such as leaks or blockages that could hinder the delivery of gases when they are needed most. In contrast, other portions like reserve supply or primary supply may not be actively in use at that time and hence are not a focus during inspections regarding current operational readiness. Understanding the condition and maintenance of the operating supply helps ensure compliance with safety standards and the efficient functioning of medical gas systems.
