Which statement is NOT a best practice when handling refrigerant cylinders?

• A. Store upright away from heat
• B. Keep caps on
• C. Store near direct sun
• D. Label and segregate refrigerants

Answer: (C)

Storing refrigerant cylinders safely centers on controlling heat, protecting the valve, and clearly identifying contents.

Keeping cylinders upright and away from heat helps protect the valve and relief devices, and prevents heat from increasing internal pressure that can stress the cylinder or cause leaks. Maintaining the cap on protects the valve from damage and accidental release during handling. Labeling and segregating refrigerants ensures you know exactly what is inside each cylinder, prevents dangerous mixing or incorrect recovery, and keeps track of what material you’re dealing with.

Storing cylinders near direct sun is not a best practice because sunlight and heat raise the cylinder temperature and pressure, increasing the risk of leaks or a dangerous failure.
