Not so - it's the current that causes a fire.
Actually it is the energy current times voltage.

For a given fault twice the voltage equals twice the current!

No again. Faults are not normally ohmic. Higher v creates much higher
i, and of course higher v means lower i breakers... result is a big
difference in fire rates, favouring 240. 240 clears faults much better.
