Crystalline Silica (SiO2) refers to a group of minerals composed of silica and oxygen. It is often found in asphalt, concrete, and rocks. When these materials are abraded, crushed, milled, mined, or transported many of the particles are small enough to become respirable or inhaled. Breathing dust that contains crystalline silica puts workers at risk for serious health problems.
Why is Silica Dust Dangerous?
Inhalation of Crystalline Silica Dust over time causes many health risks including:
Lung with Silicosis vs. Healthy Lung
Overtime, silica dust inhalation may cause Silicosis. This is an irreversible and often fatal condition. Smoking combined with silica exposure increases risk and severity of Silicosis.
