Proper storage and handling of recovered refrigerant are critical to prevent contamination, leakage, and environmental harm. Recovered refrigerant should be stored in certified cylinders or tanks, which are designed to prevent leakage and corrosion. The cylinders or tanks should be labeled and dated, and stored in a cool, dry place, away from direct sunlight and heat sources. Technicians should also follow proper safety protocols when handling recovered refrigerant, including wearing personal protective equipment and ensuring good ventilation.
