The labeling shall be what for all components of the system?

The requirement for labeling all components of the medical gas system to be verified is of utmost importance to ensure safety and compliance with standards. Verification means that the labels on the components have been thoroughly checked to confirm their accuracy and reliability, ensuring that all information presented is correct and corresponds with the specifications of the system.

Proper labeling is critical in medical environments as it aids in the identification and differentiation of various gases, thus playing a vital role in preventing mix-ups that could lead to serious safety hazards. Verification of the labeling involves confirming that the descriptions, colors, and symbols used adhere to established codes and regulations related to medical gas installations.

In contrast, the other options that involve addressing, confirming, or being removable do not convey the same level of diligence and standard adherence as verification does. While those actions may pertain to aspects of installation or maintenance, they do not specifically ensure that the labeling meets the strict guidelines required for medical gas systems. Therefore, having labels that are verified facilitates compliance, safety, and operational efficiency in healthcare settings.
