I am not a chemist nor a fire/explosive expert but as far as I know
kerosene, petrol and diesel are not flammable till is in liquid form. They
need to have a certain amount of air-fuel mixture to be able to lit it up.
BTW not sure if that could happen but if there is any open electrode of both
anode and cathode then it can break down the water to oxygen and hydrogen
gas which is highly flammable if mixed that even the smallest spark can
cause a fire. Not sure if a microelectronic device could do this thing.
