Under what condition should fueling be avoided while passengers are aboard?

• A. In a closed building
• B. Outdoors with ventilation
• C. In a garage with the hood open
• D. In a service bay

Answer: (A)

Gasoline vapors are dangerous and can ignite if they encounter a spark. In a closed building, there’s little airflow to clear those vapors, so they can accumulate quickly and create a fire or explosion risk around the vehicle and anyone nearby. When passengers are aboard, this exposure is especially risky. Fueling outdoors in a well-ventilated area prevents vapor buildup and reduces the chance of a hazardous situation. Even with a garage or service bay setting, vapors can still accumulate if ventilation isn’t adequate, so the safest practice is to avoid fueling in enclosed spaces.
