The great Fanta Hege pulling a level lava flood lever?
Wow... just wow...
It's just the room, actually: note the three visible dots at the very top of his vision, indicating there's floor that is not lava. Also, the floor message from the previous screenie doesn't hint at gasoline.
Still, I'm surprised he went for the switch, seeing as how there weren't any blood levers (and that's about the only thing that would handle Lost Souls).
