In a non-anesthetizing Category 1 space, where should the area alarm pressure/vacuum sensor be positioned?

In a non-anesthetizing Category 1 space, positioning the area alarm pressure/vacuum sensor at the station outlet/inlet is critical for effective monitoring and safety. This location allows for immediate detection of any changes in gas pressure or vacuum at the point where gas is delivered to the user. By having the sensor here, it can effectively alert staff to any potential issues before they reach the patient care area, ensuring that the integrity of the medical gas system is maintained.

The station outlet/inlet serves as the last line of defense to monitor the gas supply before it enters the treatment space. If there is a drop in pressure or a vacuum failure, it indicates a problem that could affect patient care, making this positioning paramount for prompt action.

The other locations, while relevant in their own contexts, do not provide the same level of immediate oversight for the area where gas is actively being used. For instance, placing the sensor at the valve inlet or near gas storage would monitor conditions further upstream from the point of use, which could delay response times in an emergency or operational failure situation. Similarly, positioning it near the suction point would not capture the overall status of the gas delivery system but would only indicate conditions right at the suction device. Thus,
