bead blast sand substitute

As far as personal protection from silicosis, it's kind of like avoiding STDs ... any protection is better than none at all. If all you can afford is a paper filter mask, a pair of cheap sunglasses and your dad's old flannel shirt, that's better than nothing.

Contrarily, bikers say if you have a ten dollar head, then buy a ten dollar helmet.

When I have to suit up to use my "big dog" pot blaster outside (6 cubic feet a minute at 120 psi), I wear my particle filter cartridge mask with built-in goggles, leather gloves and long sleeved shirt, and wrap my hair in a towel. (I don't care about getting dirty -- that's a regular daily part of my job LOL :-D -- but I just hate having Media Hair.)
