Acute Silicosis



Silicosis is a lung disease. It is caused by breathing dust that has crystalline silica in it. In acute silicosis, the disease happens after weeks or months of being around high levels of silica.


Silica dust can come from cutting, drilling, breaking, or grinding soil, sand, granite, or other items. It becomes trapped in the lungs when the dust gets in the air that people breathe.

Risk Factors

The risk is higher in people who spend time around air that has silica dust in it. Jobs that involve these tasks also raise the risk:

  • Sandblasting
  • Construction
  • Wrecking and demolition
  • Abrasive blasting
  • Masonry
  • Concrete finishing
  • Drywall finishing
  • Rock drilling
  • Stone milling or cutting
  • Mining
  • Sand and gravel screening
  • Rock crushing (for road base)
  • Agriculture
  • Ceramics, clay, pottery
  • Glassmaking
  • Vitreous enameling of china plumbing fixtures
  • Making soaps and detergents



Symptoms may appear within a few weeks to five years after exposure.

Problems may be:

  • Trouble breathing
  • Coughing
  • Weakness
  • Fever
  • Weight loss


The doctor will ask about your symptoms and health history. You will also be asked about your work history. A physical exam will be done.

Pictures may be taken to look for signs of damage. This can be done with a chest x-ray.

There is no cure. The goal of treatment is to avoid silica dust. Other options are:

  • Avoiding smoking
  • Medicines to improve air flow, ease cough, or treat infection
  • Oxygen therapy to support breathing
  • Lung rehabilitation
  • A lung transplant


The risk of this problem may be lowered by:

  • Avoiding air that has silica dust in it
  • Wearing a mask or respirator on the job to avoid breathing in air that has silica dust in it
  • Working in well-ventilated areas
