If medical gas systems operate at pressures other than standard gauge pressures, what must be listed on the station outlet identification?
Correct Answer:
Name of the gas and nonstandard operating pressure
Explanation:
When a medical gas outlet is not at the standard pressure, the label must communicate exactly what gas it is and the actual pressure it delivers. This combination prevents dangerous mix-ups and ensures the correct equipment and settings are used. If you only label the gas name, staff won’t know the pressure and could misconfigure regulators or flow devices. If you label only the nonstandard pressure, there’s no indication which gas is involved, leading to potential misdelivery. By listing both the name of the gas and the nonstandard operating pressure, anyone using the outlet has all the essential information to connect safely and deliver the right therapy. The other options don’t provide both pieces of critical information required for safe use.
