Which of the following is included in the components needed for oxygen service?

In the context of components needed for oxygen service, the inclusion of sealed and labeled components is critical for ensuring safety and compliance with standards in medical gas systems. Oxygen, as a highly reactive gas, poses significant risks if not handled correctly. Sealed components prevent contamination and reduce the risk of accidental leaks, which can lead to dangerous situations. Labeling is equally important as it provides essential information about the contents, allows for proper identification of components, and ensures that they are used correctly in accordance with industry regulations.

Sealed and labeled components also reflect adherence to specific guidelines established by organizations such as the National Fire Protection Association (NFPA) and the Compressed Gas Association (CGA). Proper labeling helps staff quickly recognize which components are safe for use with oxygen, contributing to overall operational safety and efficiency.

While elements like plastic fittings, low-pressure valves, and open containers may have their uses in various applications, they do not align with the stringent requirements for components intended specifically for oxygen service. Such materials may be unsuitable due to their potential for igniting or failing under the specific conditions associated with oxygen-rich environments.
