crystalline silica dust. For any kind of dust, there are different particle sizes. When dust is inhaled, its point of deposition within the respiratory system is very much dependent upon the range of particle sizes present in the dust. It is the respirable (smallest particle size) fraction of crystalline silica dust which is of critical concern for its health effects, since these can penetrate
That dust is also hydrophobic, meaning it fails to mix with water. Pair that with the stricter requirements, and even contractors using wet method can struggle to contain silica dust. To combat this, some companies choose to add a silica dust suppressant, such as Chemek’s NeSilex, to the water to break down the barrier between the dust and water.
