Silica dust (crystalline silica) is just one of the many air contaminants that poses a health risk to those who are exposed to it without adequate respiratory protection.
Found in stone, rock, sand, gravel and clay, silica is commonly in products such as reconstituted stone, granite and sandstone along with building materials like bricks, mortar, tiles and concrete.
According to the Cancer Council, due to the microscopic size of the silica dust particles, exposure can lead to the development of lung cancer, silicosis (an irreversible scarring and stiffening of the lungs), kidney disease and chronic obstructive pulmonary disease.
