What is a potential consequence of filling refrigerant into the wrong recovery cylinder?

Filling refrigerant into the wrong recovery cylinder can lead to contamination and potential hazards, making this option the most accurate. When different types of refrigerants are mixed in a cylinder, it compromises the purity of the refrigerants within. This can occur because each type of refrigerant has a distinct chemical composition and pressure characteristics. When these substances are mixed, it can result in dangerous reactions, posing risks to both safety and equipment.

Additionally, contamination can lead to inefficiencies in systems that rely on specific refrigerants for optimal performance. If the mixture is used unknowingly in a system, it can cause mechanical failures, release harmful substances, or lead to environmental concerns.

The other options do not accurately capture the serious implications associated with incorrectly filling recovery cylinders. For example, enhanced efficiency during recovery or reduced handling time are misleading, as those cannot occur without risking safety and proper function. Loss of refrigerant could potentially occur, but the more serious and immediate concern is the contamination and associated hazards.
