Silica ExposureSilica exposure occurs when dust that contains crystalline silica particles is inhaled. It is estimated that approximately 1,200,000 workers are exposed to silica each year. Silica, or silicon dioxide, is a naturally occurring mineral that is composed of one silicon atom and two oxygen atoms. When silica molecules line up and create a repeating pattern they form a crystal (crystalline silica). Different crystal patterns are given different names; the most common is quartz. Silica is a major component of sand and granite. Materials that contain crystalline silica: * Brick For more information about Silica Exposure, please contact us directly. |
