How can high-pressure cylinders containing aviation oxygen be identified?

High-pressure cylinders containing aviation oxygen are specifically identified by their green color and the labeling that states 'AVIATOR'S BREATHING OXYGEN.' This color and label combination is standardized in the aviation industry to ensure that personnel can quickly and accurately identify oxygen cylinders meant for breathing purposes.

The use of green coloring signifies that the cylinder is filled with aviation oxygen, which is purified and suitable for use in aircraft, distinguishing it from other gas types. The label 'AVIATOR'S BREATHING OXYGEN' provides further clarification of the contents, emphasizing its intended use for pilots and passengers in aviation settings.

This identification system is crucial for safety, ensuring that there is no confusion with other potentially hazardous gases, which might be indicated by different colors and labels. Understanding these specifics is essential for proper handling, storage, and emergency procedures associated with aviation oxygen.
