bead blast sand substitute

I use the high school science class full nerd science goggles, a bandanna to cover the forehead / head, 3m paper / cloth face mask, form fitting gloves, slim fit long sleeve shirt and I blast outdoors. If indoors I would run a big fan to evacuate suspended dust.

So, is it the consensus that these steps/equipment are good enough safety precautions for outdoor blasting? Silicosis scares the crap outta me.
