Gas hose color coding helps prevent dangerous mixups by visually identifying what gas is flowing. Oxygen hoses are green, while fuel gas hoses (like acetylene) are red. This distinction matters because oxygen supports combustion and can dramatically increase flame intensity if it’s delivered through the wrong line or into a system not designed for it. Using the green oxygen hose keeps the supply correctly identified and reduces the risk of accidental cross-connection. If you ever see hoses with unexpected colors, stop and verify with labels or the system documentation before proceeding.
