a wet SOS pad should be alright in keeping the dust to a minimum right ?
Tuner, I don't know if adding water to the mix will make it safe or not. When I made the mistake, I could see the dust in the rays of sunlight as it came thru the windows...and I immediately took the work outside...but obviously for me...it was too late.
As a note, I was using fine grit Emory cloth and not regular sand paper and I am a low level asthmatic, so my resistance would naturally be low.
