It is similar to both silicosis from inhaling silica dust and asbestos dust. Due to silica dust exposure, many workers developed silicosis, a debilitating lung disease. Long-term inhalation of silica dust causes silicosis, a fatal disease of the lungs. Potash miners are liable to develop silicosis. Silica flour has been associated with all types of silicosis, including acute silicosis. Finally, it releases silica particulates during the pour, risking silicosis in foundry workers. Long-term exposure to the dust may cause a more serious respiratory disease similar to silicosis. Enlargement of the hilum is common with chronic and accelerated silicosis. There have been no documented cases of silicosis developed from exposure to volcanic ash. From 1991 to 1995, China reported more than 24,000 deaths due to silicosis each year. This finding is not pathognomonic (diagnostic) of silicosis. After hundreds of deaths from silicosis, the town was nicknamed "The Widowmaker". There are three key elements to the diagnosis of silicosis. Preventing silicosis in may require specific measures. Second, chest imaging (usually chest x-ray) that reveals findings consistent with silicosis.
