Silica is a main part of sand, so glass workers and sandblasters are also exposed to silica. Three types of silicosis occur: Chronic silicosis, which results from longterm exposure (more than 20 years) to low amounts of silica dust. The silica dust causes swelling in the lungs and chest lymph nodes.
