What is the color code for cylinders containing R-22?

• A. Dark green
• B. Light green
• C. Orange
• D. Blue

Answer: (B)

The correct color code for cylinders containing R-22 is light green. This color coding system helps identify refrigerants and their associated safety classifications. For R-22 specifically, the light green color indicates that it is a hydrochlorofluorocarbon (HCFC) and helps distinguish it from other refrigerants, which may have different colors to signal differing properties or chemical compositions. Understanding the significance of these color codes is crucial for HVAC technicians and others working with refrigerants. Using the correct color ensures safety and compliance with regulations regarding refrigerant handling and storage. In addition, recognizing the light green color of R-22 cylinders can help technicians quickly and accurately identify the refrigerant they are working with or need to handle, minimizing the risk of errors in identifying and using the correct material in HVAC systems.
