• Gasoline vapor behavior in an enclosed space • Difference between vapors and liquid fuel • How vapor density affects where fumes accumulate on a boat

💭 Think About

• Think about whether gasoline vapors are heavier or lighter than air, and where they would naturally collect inside a hull. • Consider if electrical sparks, hot surfaces, or static electricity could ignite vapors, or if it really must be an open flame. • Picture where vent outlets should safely discharge vapors in relation to where air is being drawn into the engine.

✅ Before You Answer

• Verify where heavier‑than‑air vapors will settle inside a vessel. • Check if ignition sources are limited to open flame or include other sources like switches and motors. • Confirm the intended purpose of fuel-tank vent outlets and where they should release vapors.
