Crystalline silica exposure WorkSafeBC

Silica is used in a wide variety of materials including concrete, cement, asphalt, bricks, and stone (granite) countertops. Workers may be exposed to crystalline silica dust through activities such as sanding, cutting, drilling, grinding, crushing, demolition, and the cleanup of silica-based materials.

Crystalline Silica Dust: The Threat Industrial Vacuum

Industries partaking in crushing, grinding, drilling, sawing, and cutting materials such as sand, stone, concrete, mortar, and more are where these particulates become airborne pathogens. When the mass of the material is broken or cut, crystalline silica dust becomes more lethal, as it can be almost 100 times smaller than ordinary sand.

Tool Box Talk- Crystalline Silica Exposure Prevention

Exposure to crystalline silica often occurs as part of common workplace operations involving cutting, sawing, drilling, grinding/sanding and crushing of natural and engineered stone products such as granite and slate and also in the quarrying of these materials. Over-exposure can lead to serious, sometimes fatal illnesses including silicosis

Guidance for Controlling Silica Dust from Stone Crushing

like scleroderma and rheumatoid arthritis. Freshly fractured crystalline silica particles are considered the most fibrogenic as they are capable of entering the gas-exchange regions of the lungs, thus increasing the importance for the control of respirable silica dust generated from stone crushing units. Figure 1. Stone crushing

Assessment of Occupational Dust and Silica Exposure in

The fact that the HEMM operators worked in enclosed cabins further helped reduce the exposure of the HEMM operators. Helpers in the crusher area were highly exposed to crystalline silica as compared to mining workers. As portrayed in Figure 1 dust generation occurs during various stages at stone crushing units and in the stone
