Where should the pressure in the main line of each medical gas system, and the operation and condition of the source of supply, be monitored?

The pressure in the main line of each medical gas system, as well as the operation and condition of the source of supply, should be monitored through a master alarm. Master alarms are specifically designed to provide a comprehensive overview of multiple systems and can alert medical staff to any issues within the medical gas supply infrastructure. They typically monitor critical parameters from various points within a facility, including pressure levels and equipment status.

Using a master alarm allows for centralized monitoring, enabling quick responses to potential failures or abnormalities in the gas supply. This is essential in healthcare settings where uninterrupted access to medical gases is crucial for patient care.

In contrast, area alarms and local alarms typically provide information about specific zones or equipment rather than offering a facility-wide overview. Security alarms do not pertain to the technical monitoring of medical gas supply systems and focus instead on the safety of the premises and prevention of unauthorized access. Therefore, the master alarm is the appropriate choice for monitoring the main line pressure and overall system condition in a medical gas setup.
