Q

Compared to air, the weight of liquefied petroleum gas vapors are which of the following?

🔍 Key Concepts

• Physical properties of liquefied petroleum gas (LPG) compared to air • How gas density or vapor density affects whether a gas rises or sinks • Behavior of LPG leaks in confined or low-lying spaces (bilges, pits, lower decks)

💭 Think About

• If LPG escapes from a cylinder or line on deck, would you expect the vapors to collect in high places or low places? Why? • Think about safety: when checking for LPG accumulation on a vessel, would you be more concerned about overhead spaces or bilges and drains? • How does the density of a gas compared to air determine where it tends to go in still air conditions?

✅ Before You Answer

• Recall whether LPG vapors tend to settle or rise in an enclosed space on a vessel • Consider standard safety warnings about where LPG can accumulate on small craft and in machinery spaces • Verify how vapor density relative to air (greater than, equal to, or less than 1) affects whether a gas is lighter or heavier than air
