Silica Dust From Limestone Quarry
Health Hazards of Mining and Quarrying - ILO .
Freshly fractured silica dust appears to be more reactive and more hazardous than old or stale dust. This may be a consequence of a relatively higher surface charge on freshly formed particles. The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock.

Dust containing crystalline silica in construction work - .
Dust containing respirable crystalline silica particles is commonly called silica dust. Activities such as cutting, grinding, sanding, drilling, loading or demolishing products that contain silica can generate respirable particles of crystalline silica dust that are small enough to breathe into your lungs.
