Station outlets and inlets of manufactured assemblies that employ hose or flexible connections to the piping system that are not fully and immediately accessible shall use what type of connectors?

The selection of D.I.S.S. (Diameter Indexed Safety System) connectors for station outlets and inlets of manufactured assemblies that utilize hose or flexible connections is appropriate because D.I.S.S. connectors are designed to prevent the misuse of medical gas systems by ensuring that only the correct gas can be connected to the intended outlet or inlet.

These connectors feature a unique diameter index system, which means that each type of gas has a specific connector size and shape, preventing cross-connection between different gases. This is crucial in a medical setting where the incorrect gas supply can lead to serious health risks for patients.

Moreover, D.I.S.S. connectors are specifically intended for use in environments where there may be some limitations on accessibility, as they provide a secure and reliable connection while allowing flexibility in the system. Their design helps maintain the integrity of the gas flow and ensures the safety of patients and healthcare providers.

In contrast, the other connector types listed do not necessarily provide the same level of safety and specificity required for medical gases. While some options may have applications in different contexts, they do not adhere to the stringent safety standards and requirements that D.I.S.S. connectors do.
