What is a consequence of refueling with passengers still in the vehicle?

Increased risk of fire hazards
Faster refueling times
Enhanced supervision of riders
Improved operational readiness

The correct answer is: Increased risk of fire hazards

Refueling a vehicle with passengers still on board presents a significant safety concern, primarily due to the increased risk of fire hazards. When refueling, the fuel can generate vapors that are flammable and can ignite if there is a spark or open flame nearby. Having passengers in the vehicle can complicate evacuation or response in the event of an emergency, making it more challenging to manage a fire or other hazardous situation. When passengers are outside the vehicle during refueling, it minimizes the risk of injury in case of an accident or fire, as they can be quickly evacuated to a safe distance. Additionally, the presence of passengers can distract the operator during the fueling process, further elevating the potential for accidents. Therefore, having passengers in the vehicle during refueling significantly heightens the chance of a dangerous incident.
