What are the common pin positions for oxygen in the PISS?

The correct choice regarding the common pin positions for oxygen in the Pin-Index Safety System (PISS) is indeed based on the unique way that gas cylinders are designed to prevent accidental connections. In the PISS used for medical gases, each type of gas has specific pin positions that match the corresponding outlet on the yoke of the regulator.

For oxygen, the pin positions 2 and 5 are designated specifically to ensure that only the correct gas cylinder can be attached to the regulator and vice versa. This system is part of a broader safety protocol, ensuring that gases are not mixed up, which is crucial in healthcare settings where the precise delivery of gases like oxygen is vital for patient safety.

This unique configuration helps healthcare professionals quickly and easily identify the correct regulator for oxygen tanks, minimizing the risk of misuse or accidental connection to the wrong gas supply. The safety mechanism of the PISS is integral to maintaining a safe environment when managing medical gases. Understanding these pin positions is key in ensuring effective training in medical gas tank safety practices.
