I used to work at a company that used 'real sand' for blasting/finishing cast aluminum parts. Even though we were using a ventilated blasting cabinet the sand dust (free silica) was everywhere, and I mean everywhere. Our insurance agent and an OSHA representative showed up within 2 weeks of each other, both men STRONGLY RECOMMENDED (hint, hint, nudge, nudge) that we switch to a different media before their follow up visit and final reports. They both suggested switching to walnut shells, recycled buttons (plastic), aluminum oxide and several other media. After trying various media samples we settled on, and switched to, aluminum oxide.
Be careful if you're using sand, it, along with the potential for silicosis, is some nasty stuff. I hope you find the above links informative.
