The refrigerant cylinder designed to hold recovered refrigerant is characterized by having a grey body and a yellow top. This color coding is established to help technicians quickly identify the purpose of the cylinder while ensuring compliance with safety and environmental regulations.

In this case, the grey body indicates that the cylinder is specifically for recovered refrigerant, while the yellow top signifies that it is a type of cylinder where refrigerants are stored for reclamation or recycling. Such color conventions are crucial in the HVACR industry for maintaining safety standards and preventing cross-contamination with other refrigerant types.

Other color combinations, such as those with yellow bodies or other hues, are designated for different purposes or types of refrigerants. Thus, the identification of the correct colors for recovered refrigerant cylinders is fundamental for proper handling and disposal according to EPA regulations.
