Which of the following is essential for proper refrigerant recovery?

Proper refrigerant recovery is critical for environmental safety and compliance with regulations. Using separate designated tanks is essential because it ensures the refrigerants are collected and stored appropriately without contamination or mixing. Each type of refrigerant has specific properties and recovery requirements, and contamination can affect the refrigerant's chemical composition, making it unsuitable for recycling or reuse.

Designated recovery tanks are also designed to handle particular refrigerants safely, preventing them from escaping into the atmosphere, which aligns with regulations aimed at minimizing ozone depletion and global warming potential. Therefore, keeping refrigerants in separate tanks allows for proper processing later, ensuring that the refrigerant can be recycled or disposed of according to regulatory guidelines, thus supporting both safety and environmental responsibility.
