When should you never fuel your bus if there are riders on board?

Fueling a bus while there are passengers on board is a critical safety concern, and doing so in a closed building significantly heightens the risks associated with the process. A closed building can trap flammable vapors and fumes, increasing the potential for dangerous situations, including fires or explosions. Adequate ventilation is essential when handling fuel, and a closed environment does not provide that.

While fueling near busy intersections could pose safety risks due to traffic, and having windows open could potentially expose riders to fuel vapors, these situations do not present the same level of conversation regarding immediate danger as fueling in a closed space does. Such environments not only increase flammability risks but also can compromise air quality and the health of everyone on board the bus. Therefore, fueling in a closed building is a definitive situation where passengers should never be on board.
