Rock Crushing Silica Amp Amp Noise
Crusher Plant Dust Suppression: Silica compliance & Safety
Proper Crusher Dust Control: What It Needs. Controlling and minimizing exposure to silica dust requires proper wet dust suppression for rock crushers. Because water has a relatively high surface tension (72 dynes per cm), it alone cannot penetrate crushed material that releases silica dust.

Silica, it's not just dust!
Are you exposed to silica dust? If you crush, cut, grind, saw or drill materials that contain silica, dangerous crystalline silica dust is released into the air. Microscopic particles of this silica can permanently damage your lungs over time, leading to diseases such as silicosis and lung cancer.

Silica
Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases the dust. As workers breathe in the dust the silica settles in their lungs. For information on protecting workers from harmful exposure to silica dust, see the resources section below, which includes a silica control tool.
