Which gas is typically stored in black-coded medical gas cylinders?

Explanation:
Gas cylinder color coding is a quick way to identify contents and prevent mix-ups. In many hospital color schemes, the black body indicates nitrogen. Nitrogen is an inert, non-reactive gas used as a purge or inerting gas, to blanketing lines, or to provide a non-oxidizing environment in various procedures. It is not intended for patient inhalation, which is why it isn’t used for respiratory needs. Oxygen is typically green, and other gases like helium or air have different color associations. So, a black-coded cylinder is most commonly nitrogen.
