Does gritting with super fine sandpaper like he does can produce toxic dusts (inhalable) when working with electronic parts made of various materials...) ?

  He was wet sanding towards the end which does help reduce dust. A mask would be wise though.

    Wet sanding also prevents the sandpaper from clogging up as quickly, making it last longer.
