🔍 Key Concepts

• Fire and explosion risk from gasoline vapors in small craft • Proper ventilation and shut-down procedures during fueling • Need for expansion space in fuel tanks when temperature changes

💭 Think About

• Think about which actions reduce the chance of gasoline vapors igniting during fueling. • Consider what happens to fuel when it warms up after being pumped into a cool tank — how should the tank be filled to allow for that? • Ask yourself which three options clearly improve safety, and which one might actually create a different kind of hazard.

✅ Before You Answer

• Verify which practice is recommended in standard small boat fueling procedures (e.g., USCG safety guidance). • Check which step could lead to fuel spilling or over-pressurizing a tank when the fuel expands. • Confirm that the correct answer is the one unsafe or incorrect practice, not the ones that enhance safety.
