Not every aircraft has the capability to dump fuel. I think it may only be Boeing aircraft that have that capability. I know on the 747 when fuel is dumped it comes from valves at the ends of the wings, well above and away from the engines. I am sure that with the speed of the aircraft the fuel would dissipate rather quickly with no chance of ignition.
