What color are hoses used for oxygen?

Hoses used for oxygen are color-coded green. This standard is widely recognized in various industries, including welding and metalworking. The use of a specific color for oxygen hoses helps to ensure safety by preventing the accidental connection of the wrong gas. In many settings, red is often used for acetylene or fuel gases, while blue is commonly associated with inert gases such as nitrogen. Black hoses can also be used for various types of fuel gases but do not have a specific designation for oxygen. The green color for oxygen hoses is part of an established color-coding system that enhances safety and operational efficiency by making it immediately clear which hoses should be used for which gases.
