851 Silica Dust Safety in Construction
Skip to main content

Symptoms of Exposure

Chronic silicosis may go undetected for years in the early stages; in fact, a chest X-ray may not reveal an abnormality until after 15 or 20 years of exposure. The body's ability to fight infections may be overwhelmed by silica dust in the lungs, making workers more susceptible to certain illnesses, such as tuberculosis. As silicosis progresses, you may exhibit one or more of the following symptoms:

  • shortness of breath following physical exertion
  • severe cough
  • fatigue
  • loss of appetite
  • chest pains
  • fever

If You Are Exposed

If you believe you are overexposed to silica dust, visit a doctor who knows about lung diseases. A medical examination that includes a complete work history, a chest X-ray, and lung function test is the only sure way to determine if you have silicosis. The National Institute of Occupational Safety and Health (NIOSH) recommends medical examinations occur before job placement or upon entering a trade, and at least every 3 years thereafter.
