In the context of safety codes, what does the color black represent in medical gas systems?

In medical gas systems, the color black is designated for nitrogen. This color coding is established to ensure safety and facilitate easy identification of different gases within the healthcare environment. Nitrogen is often used in medical applications for various purposes, such as powering pneumatic devices or for creating an inert environment.

The use of a consistent color code, including the designation of black for nitrogen, is crucial for preventing mistakes during handling or connecting gas lines. Each medical gas is associated with a specific color to ensure that healthcare personnel can quickly and accurately identify the type of gas being used, thereby reducing the risk of accidents or contamination.
