What color is an oxygen hose generally colored?

The color of an oxygen hose is generally colored blue. This color-coding system is widely used in welding and cutting operations to ensure safety and prevent mix-ups between different gases. Blue is specifically designated for oxygen to clearly differentiate it from other gases, such as acetylene, which is typically colored red, and nitrogen, which is often green.

Having a standardized color helps workers quickly identify hoses and regulators, reducing the risk of accidental connections that could lead to dangerous situations. By maintaining this clear visual cue, operators can ensure they are using the correct equipment and gases for specific applications, which is critical in soldering and brazing processes where the precise composition of gases can affect the quality and safety of the work being performed.
