🔍 Key Concepts

• ASHRAE refrigerant color-coding standards for cylinders • Common refrigerants used on vessels: CFC-12, CFC-11, HCFC-22, HFC-134a • The specific color associated with light (sky) blue cylinders

💭 Think About

• Which of these refrigerants is most commonly linked to light (sky) blue cylinders under industry standards? • Can you recall which refrigerant is often associated with automotive or small refrigeration systems and its cylinder color? • Eliminate any refrigerants you know are linked to other cylinder colors (e.g., white, orange, green).

✅ Before You Answer

• Match light (sky) blue to the ASHRAE standard color for one of the listed refrigerants • Confirm that the refrigerant you pick is commonly used in marine and HVAC systems in that color cylinder • Be sure you are not confusing light blue with white, cream, or light green commonly used for other refrigerants
