Q

What type of liquid is used in the liquid P/V breaker?

🔍 Key Concepts

• Function of a liquid P/V breaker in a cargo tank venting system • Why the sealing liquid must remain effective in cold weather and not contaminate the cargo • Differences between using water, antifreeze mixtures, and oil in open deck equipment

💭 Think About

• What happens to plain water in the P/V breaker if the ship is trading in very cold climates? • Would you want the liquid in the breaker to be the same as the cargo, or something neutral and easy to handle on deck? Why? • Which option best keeps the seal working while avoiding cargo contamination and mechanical damage?

✅ Before You Answer

• Check which liquids could freeze and block the venting system. • Eliminate any choice that could contaminate the cargo or create an unsafe vapor situation. • Confirm which option is commonly used as a non-reactive sealing liquid in tank vent systems, especially on tankers.
