What color are industrial oxygen hoses usually coded for gas service identification?

Industrial oxygen hoses are typically color-coded green for gas service identification. This color coding is important for safety and consistency in the handling of gases; green specifically indicates oxygen, helping to prevent any confusion with hoses carrying flammable gases or other substances. Proper identification through color coding is crucial in a work environment to ensure safety protocols are followed, reducing the risk of accidents or misuse of equipment. Other colors, like red and blue, have specific associations with different gases, such as acetylene or inert gases, which further emphasizes why green is reserved for oxygen.
