Sandblasting operations are a long-recognized hazard. Not only can you get silicosis but sandblasting is an abrasive process and what else besides the sand is hanging around in the air? Tiny bits of the substrate metal? Zinc (galvanizing coating), Cadmium (another plating), Chromate (paint), Lead (paint)? Is a cured cyanoacrylate paint passivated enough that it's safe to breathe its dust? When I was a kid I didn't have anyone to tell me and no reminders to wear a respirator. Edit: after submitting, I realized I've never used "silicon" sand as a blasting abrasive, but only glued to paper or cloth. I typically blast with aluminium oxide, coal slag, or glass beads.
