What color are low pressure oxygen cylinders typically?

Low pressure oxygen cylinders are typically colored yellow to indicate their specific use for breathing oxygen. This color coding helps to easily identify the cylinders and prevents confusion with other types of gas cylinders that may be used in various applications, which often have different colors. Yellow is a widely recognized standard in aviation and medical contexts for low pressure oxygen, ensuring that personnel can quickly and accurately identify the cylinder's function and ensure safe operation during flight.

The other colors mentioned usually denote different gases; for instance, a green color is often used for high-pressure oxygen cylinders, while red is frequently associated with fire or flammable gases. Blue is typically used for other medical gases, so recognizing the yellow color specifically for low pressure oxygen aids in maintaining safety protocols.
