What is the PIN index hole position for O2?

The correct answer, indicating the PIN index hole position for oxygen (O2), is 2 and 5.

In medical gas cylinder storage, the PIN (Pin Index Number) system is crucial for ensuring that each type of gas has its own unique connection point. This system prevents the accidental exchange or misuse of different gases, promoting safety in storage and administration.

In the specific case of oxygen, its designated positions on the PIN index are holes 2 and 5. When connecting to the appropriate regulator, these pin positions align correctly, allowing for secure and proper attachment. The arrangement is standardized to facilitate safe handling and reduce the risk of mixing different gases that may pose safety hazards if used inappropriately.

Understanding the PIN index system is essential for anyone handling medical gases, as it signifies the importance of recognizing and adhering to the specific configurations that ensure only compatible equipment is utilized with each type of gas.
