What color code is associated with oxygen regulators?

  1. Yellow

  2. Red

  3. Green

  4. Blue

The correct answer is: Green

Oxygen regulators are designated by the color green. This color coding is a standard practice within various industries involving gas handling to ensure safety and prevent mixing gases, which can lead to dangerous situations. Green is universally recognized for oxygen, making it easier for workers to quickly identify and handle the correct gas equipment. The significance of color coding cannot be understated, as it plays a critical role in operational safety. By using green for oxygen, workers can assist each other in maintaining proper protocols and reducing the risk of accidents related to gas supply. Familiarity with these color codes is essential for anyone involved in the handling, transport, or management of gases in a millwright setting.
