What is the color code for R-12 disposable refrigerant cylinders?

White
Blue
Red
Green

The correct answer is: White

The color code for R-12 disposable refrigerant cylinders is indeed white. The use of a standardized color-coding system helps to identify different types of refrigerants and enhances safety by reducing the risk of improper handling or mixing of refrigerants. R-12, a chlorofluorocarbon (CFC) once widely used in refrigeration and air conditioning systems, is specifically designated with this white color for its disposable cylinders. This color-coding is important within the HVAC and refrigeration industries as it enables technicians to quickly and easily identify the refrigerant in use, ensuring compliance with environmental regulations regarding the handling of substances that can harm the ozone layer. Knowing the color codes is crucial for anyone involved in the service and maintenance of refrigerant systems, as it ensures that the correct refrigerant type is used and prevents potential environmental damage.
