If you have riders aboard, you should never fuel your bus...

• A. In a closed building
• B. In an open field
• C. In a parking structure
• D. Near the engine running area

Answer: (A)

When you refuel, gasoline vapors are produced and these vapors are highly flammable. In a closed building, those vapors can collect and stay concentrated because there’s little to no ventilation. A spark from the nozzle, static discharge, or a nearby ignition source could ignite the vapors, causing a fire or explosion. With riders aboard, the risk is even more critical because you need to move people out quickly if something goes wrong, and distractions or delays increase danger. That makes fueling in a closed building strictly off-limits. Fueling in an open field or in a location with better ventilation is safer, and fueling near the engine running area is dangerous due to heat and potential ignition sources, but the enclosed-space hazard is the key reason to avoid fueling with passengers aboard in a closed building.
