What should be located immediately outside each Category 1 space and anesthetizing location for each medical gas system?

The correct answer is that a zone valve should be located immediately outside each Category 1 space and anesthetizing location for each medical gas system. Zone valves are critical components in medical gas systems, serving to control the flow of gases and allow for the isolation of specific areas within a facility. This feature is particularly important in medical settings, as it ensures that specific areas can be shut off in case of an emergency or maintenance without disrupting the supply to the entire facility.

By having a zone valve positioned just outside these critical areas, medical personnel can quickly access it if they need to manage gas flow, such as during a malfunction or leak. This placement aids in maintaining safety and ensures that patient care is not compromised. It is a vital feature in managing gases safely and efficiently.

Other components, such as emergency shut-off switches, pressure gauges, or flow meters, serve different purposes and are not specifically required to be placed immediately outside the Category 1 space. Emergency shut-off switches are typically located in accessible areas but are not necessarily outside of each medical gas system location. Pressure gauges are used for monitoring the pressure within the system rather than controlling gas flow. Flow meters measure gas flow rates but do not provide the necessary isolation function that zone valves do. Thus,
