Station outlets over 80 psi must have what type of connection?

The requirement for station outlets over 80 psi to have a DISS (Diameter Index Safety System) connection is grounded in safety and compliance standards for medical gas systems. DISS connections are specifically designed to prevent accidental cross-connections between different types of gases, which is critical in healthcare settings where different gases like oxygen, nitrous oxide, and medical air are used.

DISS connections feature a unique design that matches specific gas types with corresponding outlets, ensuring that only the correct gas can be connected to a device or delivery system. This is particularly important when dealing with higher pressures, such as those exceeding 80 psi, where the risk of incorrect gas delivery can lead to severe consequences for patient safety.

In comparison, while quick connect, screw thread, and flanged connections have their appropriate uses in various applications, they do not offer the same level of safety against misconnection. For instance, screw threads may not provide the necessary gas identification that DISS connections do, and flanged connections are more commonly used in industrial applications rather than in medical gas systems. Therefore, the DISS connection stands out as the most appropriate choice for managing higher pressures in a way that maximizes safety and compliance with medical gas standards.
