What will happen if I evaporate flouriantimonic acid and then walk trough it, will I melt, burn,...

I’m just curious 

Thank you 

Burn your lungs and eyes at a minimum.

The acid decomposes on heating to hydrogen fluoride gas, which then forms hydrofluoric acid with any moisture on your body it comes into contact with. Injuries will be as for exposure to this acid.

HF acid is particularly nasty, as it  doesn't necessarily give indication that you've been exposed to it.
I've always kept a tube of Calcium Gluconate cream nearby when I've had to work with it.
( along with all other required PPE. )

I don't think it is very volatile.
It decomposes on heating and gives HF which is ... bad for you.
