Alarm switches and sensors must be installed to ensure they are what?

Alarm switches and sensors are critical components in medical gas systems, and their installation must ensure they are removable. This is important for several reasons.

In the context of medical gas systems, having removable alarm switches and sensors allows for easy maintenance and replacement when necessary. If a sensor malfunctions or requires calibration, being able to remove it quickly without extensive disassembly of surrounding equipment or systems is vital for maintaining operational efficacy and safety standards in healthcare settings.

Additionally, removable components facilitate upgrades or changes in technology as advancements are made, ensuring the medical gas system remains compliant with current regulations and functional standards. This aspect is especially important given the ever-evolving nature of medical technologies and standards in healthcare facilities.

The other options do not accurately capture the essential characteristics required for effective installation of these components. For example, while rebuilding, reconfiguring, or restarting may be relevant in certain contexts, these actions do not emphasize the critical need for easy removal and replacement associated with maintenance and safety.
