Question

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

Quizplus · Accepted Answer

DISS (Diameter Index Safety System) is a standardized safety system designed to prevent accidental interchanging among low-pressure connectors, such as those found on flowmeters and ventilators, with a maximum pressure of 200 psig. It uses a unique combination of thread diameter, pitch, and thread form to ensure that connectors with different gases do not fit together. Therefore, it ensures the safety of gas delivery in the healthcare industry. Neither PISS nor ASSS is a recognized safety system, and CGA (Compressed Gas Association) is an organization that sets standards for compressed gases but does not specifically deal with low-pressure connectors.
