Q

What is the maximum volume to which refillable refrigeration cylinders should be filled?

🔍 Key Concepts

• Thermal expansion of liquids in closed containers • Safety margin required in pressure vessels that may be exposed to higher temperatures • Relevant USCG / CFR guidance for refrigerant cylinders on vessels

💭 Think About

• If a liquid in a sealed cylinder warms up, what happens to its volume and pressure? • Why is it unsafe to completely fill a cylinder that may later be exposed to higher ambient temperatures? • Among the choices, which one leaves a reasonable safety space for expansion while still being practically useful?

✅ Before You Answer

• Check which option leaves enough ullage (empty space) for expansion of the refrigerant. • Consider typical fill limits for portable pressure cylinders used with liquids that can expand a lot with temperature. • Verify what standard marine safety references say about maximum safe filling percentage for refillable refrigeration cylinders.
