🔍 Key Concepts

• Inert gas system purpose on tankers carrying flammable cargoes • Relationship between oxygen concentration and ability of vapors to ignite • How air (with oxygen) enters and leaves cargo tanks during loading/discharge

💭 Think About

• Which choice best relates to fire and explosion prevention in cargo tanks? • What happens to flammable vapors if the oxygen level is kept below a certain percentage? • When cargo is discharged and volume in the tank increases, what must fill that space to keep air (with oxygen) from entering?

✅ Before You Answer

• Identify which options talk about safety against ignition rather than comfort, pressure, or hull design • Recall that inert gas systems are designed to control the oxygen content in the tank atmosphere • Eliminate any option that would allow normal breathable air or focus on structural pollution regulations instead of tank atmosphere control
