Which color is used to identify R-22 on labeling?

• A. Light Green
• B. Blue
• C. Red
• D. Yellow

Answer: (A)

Color-coded labeling helps technicians quickly identify which refrigerant is in a cylinder or system, preventing cross-contamination and ensuring the right handling, oils, and recovery procedures are used. For this labeling scheme, R-22 is identified by light green. That visual cue lets you recognize the refrigerant at a glance, which is important because R-22 is an HCFC with specific servicing and disposal requirements. Seeing the light green label should prompt you to follow the correct recovery and disposal steps and avoid mixing it with other refrigerants. Other colors are used for other refrigerants, but the key point is that light green specifically designates R-22 in this color-coding system.
