CuCl of reasonable strength in a bubble etcher is no problem at all,  
indoors with no additional ventilation.
Neither is FeCl i would presume.

I used to run the bubbler closed loop, but the mist made the valves in the  
air pump stick (maybe it would've worked better had i added mist trap).  
But even with the open loop air there is minimal smell and no irritating  
fumes.
