Oxygen is associated with what color and thread direction?

• A. Green with right-hand thread
• B. Green with left-hand thread
• C. Red with right-hand thread
• D. Blue with right-hand thread

Answer: (A)

Oxygen is identified by its green color and uses right-hand threads on the cylinder outlet. The green color helps you quickly recognize the gas, and the right-hand thread means you connect oxygen regulators and hoses by turning clockwise, which is designed to fit only the oxygen system. This pairing also helps prevent cross-connecting with other gases, like acetylene, which uses left-hand threads and is typically red in color. So, green with a right-hand thread is the correct combination for oxygen.
