I use a spray booth but the primary reason is to keep overspray out of the house, not health reasons. If my health benefits, fine.
I keep the pointy end of my blades facing away from me.
I don't drink anything liquid on the bench unless it says Sam Adams or Diet Pepsi.
I wear safety glasses when running the dremel.
When I initially sit down, if I drop the first thing I pick up more than twice, I get up and walk away from the bench.
