I have been looking into MSDS of KOH of 0.1 M, and it says use proper ventilation area while working. But in my lab, we don't have fume hood to work with. And I am not able to find any safety sheet on 0.001 M KOH solution. I would also like to know about any possible health effects of this.
Only concentrated KOH is dangerous (Caustic soda). But solutions of 10 - 15 % (that is around 2 mol/l) are medically used for topical application.
I can find safety data for a KOH solution of 0.1 M at a Sigma-Aldrich site

NO STATEMENT for special ventilation is given for 0.1 M KOH
But for 0.001 M, their could be no harm at all (except do not swallow ..). No need for special ventialtion or fume hood.
Since this is a highly diluted solution you do not need a fume hood. However, you do need proper ventilation for any chemical laboratory. It could be an exhaust fans or open windows.
The question I have is how did you prepare 0.1 M? The stock solution is highly dangerous and corrosive.
Good luck
Udaya Jayasundara I did not prepare 0.1 M KOH solution in my Lab. I prepared it in other lab with facility of fumehood and PPE.
