What color identifies low pressure oxygen systems?

Low-pressure oxygen systems are identified by the color yellow. This color coding is important in aerospace physiology and engineering because it provides a quick and efficient way to recognize the type of oxygen system in use, ensuring proper handling and safety protocols.

In aviation, color coding is standardized for various systems, and yellow typically indicates low-pressure systems which operate at pressures below 100 psi. This allows personnel to easily distinguish these systems from high-pressure ones (often marked in colors like blue or red) that operate at higher pressure levels and may pose different risks or require different handling procedures. Understanding these color codes is crucial for the safety of flight operations, maintenance personnel, and the overall integrity of the aircraft's oxygen supply systems.
