Just don't put any acetone in then there's no danger.

Chances must be pretty low to get something very dangerous, but if you  
keep the acetone out nothing can happen.
It evaporates fast enough so even if you clean the board immediately  
before putting on the resist it is long gone.

I don't think it's just a matter of mixing the stuff together either, but  
the potential danger is you could make something partially effective by  
accident like it happens sometimes with carelessly discarded labware etc...
