Nitrogen, Helium, and Argon Gas Cylinders - Industrial & Lab Gases #116390 (License: Personal Use)

This illustration shows three compressed gas cylinders, each color-coded and labeled with its chemical symbol: gray for nitrogen (N₂), brown for helium (He), and green for argon (Ar). These standardized colors help ensure safe handling and identification in laboratories, medical facilities, and industrial settings. The valves and cylinder shapes reflect typical high-pressure storage designs used for inert and non-toxic gases.

Used on educational, safety, or industrial supply web pages to illustrate gas identification standards; matches user intent for learning about gas cylinder color codes or sourcing specialty gases.
