The 2 fire levers (coupe-feu) are located close to the throttles on the overhead panel. At that rate of spin, nobody could reach the levers. A similar accident happened in 1995 at le Bourget air show. This involved a AS 532 L1. Not for the same reason but with same result. Aircraft destroyed, light injuries.
That's why, if you are unable to close down the throttles you can't either close the fire levers and with the boost pumps still working, you start a fire.
In that matter, it's better on a bell 214ST with the fuel valves on the central panel.
