What color would the cylinder used to store R22 refrigerant have?

The cylinder used to store R22 refrigerant is characterized by a yellow top. This color coding helps in easily identifying the type of refrigerant contained within the cylinder, ensuring safe handling and reducing the risk of mistakes in refrigerant selection.

Refrigerants are classified with different color codes on their cylinders to denote various properties and environmental impacts. R22 is a commonly used refrigerant, particularly in older air conditioning systems, and its designation with a yellow top is established by industry standards.

Understanding these color codes is crucial for HVAC technicians and engineers as it not only aids in quick identification but also enhances workplace safety by ensuring that the correct refrigerant is used for specific systems. The other options represent different refrigerants, thus serving a separate purpose in refrigerant identification protocols.
