🔍 Key Concepts

• Fire and explosion risk from gasoline vapors • How gasoline expands when it warms up • Proper ventilation and space in fuel tanks on small boats

💭 Think About

• What happens to gasoline inside a closed tank when the temperature rises during the day? • If a tank is completely full, where can the fuel expand to—and what might that cause around vents and fittings? • If a tank is not full enough, what safety or operational problems might that create on a longer trip?

✅ Before You Answer

• Make sure the choice allows room for thermal expansion of gasoline • Avoid any option that would force fuel out vents or fittings when it expands • Avoid any option that suggests carrying unnecessary fire/explosion risk due to overfilling or excess vapors
