Occupational Dust Diseases

Who is at risk?

  • Engineered stone workers
  • Stonemasonry (natural stone) and other processing of natural stone
  • Workers in the construction industry (eg. concrete cutting, shotcreting, tunnelling, demolition)
  • Workers in abrasive blasting, fire assay lab (ore sample crushing) and other industries (quarrying, mining)
  • Workers in foundry casting

Medical practitioners are encouraged to adopt a very low threshold for investigating individuals who are at risk and to contact WorkSafe WA for the latest guidelines.

  • Engineered stone workers (category A): 2-yearly chest CT
  • Other industries (category B): 5-yearly chest CT

Not all CT scanners can perform chest CT scans at the WorkSafe WA required dose with adequate image quality.  At Perth Radiological Clinic, silica CT scans are available at the following clinic locations with more coming soon.

The introduction of engineered stone companies into the Australian market since the early 2000s has led to the emergence of an accelerated form of silicosis among young workers.

Engineered stone, also known as artificial or composite stone, is made up of a very high silica content and polymer resin. This new stone product is widely used for kitchen and bathroom benchtops.

Compared to natural granite (25-60% silica content), engineered stone (up to 95% silica content) is cheaper, easier to cut and polish, giving rise to wider exposure for workers.

Respirable crystalline silica (RCS) particles penetrate deep within the lungs. Particles that reach the alveoli are ingested by macrophages resulting in the formation of tiny silicotic nodules. Over time, coalescing nodules can then form larger nodules and fibrotic masses.

Silica is also carried to the lymph nodes in the hilum. Enlargement and calcification of the lymph nodes can develop.

Silicosis is associated with increased risk of chronic bronchitis, tuberculosis, rheumatic disorders, sarcoidosis and lung cancer.
