What is the correct color-coding of refrigerant recovery cylinders regardless of the refrigerant contained within?

🔍 Key Concepts

• Standard safety color codes used for refrigerant recovery cylinders in the U.S. • Difference between recovery cylinders and refrigerant supply cylinders (factory-charged). • Why one universal color scheme is used "regardless of refrigerant".

💭 Think About

• Think about which color (gray or yellow) is more often associated with the main cylinder body on generic/industrial gas cylinders. • Consider which bright color would logically be used on the top/shoulder of a recovery cylinder to make it quickly recognizable as "recovery" and not a virgin refrigerant supply. • Eliminate any option that looks like a specific refrigerant’s color (like R‑22 or R‑134a) instead of a universal recovery color scheme.

✅ Before You Answer

• Confirm which color is used for the body of most recovery cylinders (not the valve cap only). • Confirm which color is used for the top/shoulder to distinguish it from standard refrigerant supply cylinders. • Make sure the scheme you choose is described as universal for recovery cylinders, not just for one particular refrigerant.
