What is the color code for nitrogen gas?

Nitrogen gas is identified by a black color code in gas cylinder labeling and piping systems. This standardization is essential for ensuring safety and proper handling of medical gases. Each gas has a designated color to facilitate quick recognition, prevent mix-ups, and ensure proper usage among healthcare staff, emergency responders, and maintenance personnel.

In this context, knowing the correct color code for nitrogen helps to avoid potentially hazardous situations. For example, confusing nitrogen with an incorrectly labeled gas could lead to inappropriate use or systems being connected incorrectly. The black marking serves as a critical reference for safely managing the gas in various medical and industrial applications.
