What safety system is designed to prevent accidental interchanging among low-pressure (less than 200 psig) connectors such as those found on flowmeters and ventilators?

Question

Quizplus · Accepted Answer

The DISS (Diameter Index Safety System) is a safety system specifically designed to prevent accidental interchanging among low-pressure connectors such as those found on flowmeters and ventilators. It uses a specific thread design that is incompatible with other connectors to ensure that only connectors with matching thread designs can be connected. The other options, PISS and ASSS, are not actual safety systems, and CGA (Compressed Gas Association) focuses on high-pressure connectors, not low-pressure connectors.
