What color is the nitrogen gas outlet?

Explanation:
Color coding of medical gas outlets is a safety feature to prevent misconnections. Nitrogen outlets are colored black in many hospital systems, which makes them visually distinct from other gases—oxygen is often green, and nitrous oxide is blue, for example. This quick visual cue helps staff ensure the correct gas is being delivered and reduces the risk of attaching equipment to the wrong outlet. Keep in mind that color schemes can vary by country or facility, so always check the local color code chart or labeling on the gas panel. If anything is unclear or labeling is missing, verify before use.
