Acute Silicosis


Silicosis is a lung disease. It is caused by breathing dust that contains crystalline silica. In acute silicosis, the disease occurs after just weeks or months of exposure to very high levels of the silica. This is a serious condition. Contact your doctor immediately if you think you may have it.


Crystalline silica can be found in:
  • Concrete
  • Masonry
  • Sandstone
  • Rock
  • Paint
  • Other abrasives
  • Soil
  • Mortar
  • Plaster
  • Shingles
When these materials are cut, broken, crushed, drilled, ground, or blasted, silica dust may be produced. When silica dust gets into the air you breathe, it may become trapped in your lungs. The dust builds up damages your lungs. More dust will create more damage. This will make it hard for you to breathe.
