🔍 Key Concepts

• Function of a vent line on a pressurized dry bulk (or cargo) tank • Difference between a vent valve you operate manually and a pressure relief valve that opens automatically • Safety procedures for filling, discharging, and entering a tank for inspection or cleaning

💭 Think About

• Look at where line C is located on the tank and think: in which operations do you need a free path for air to escape or enter so the tank is NOT accidentally pressurized? • Which option describes a situation where you would most want to be absolutely sure the tank is at or near atmospheric pressure rather than under pressure? • Which answer choice sounds like an automatic safety device (relief valve) rather than a normal manually opened vent line?

✅ Before You Answer

• Confirm that line C is a vent to the atmosphere, not a discharge or filling line. • Distinguish between a pressure relief valve that opens by itself at a set pressure and a vent valve that you open by hand. • Before choosing, ask: during which listed operation would it be most dangerous if the tank were accidentally still pressurized? That’s when you would definitely open this valve.
