  • How to Reduce Silica Exposure 10 Steps (with Pictures

    Sep 06 2019 · Most harmful exposure to inhaled silica comes from chipping grinding cutting cleaning or otherwise disrupting materials like concrete or glass that contain silica. Abrasive blasting ("sandblasting") to remove paint rust etc. is perhaps the most likely source as the blasting material itself is often primarily silica. The silicon carbide abrasive in these wheels is suspended in rubber for a cushioned grind with light material removal. Norton Toolroom Grinding The abrasive grains are blended with rubber which cushions during grinding to produce a smoother surface texture than other bits with similar grits.
