Silicosis is one of the occupational respiratory diseases most commonly encountered in our setting. It is caused by inhalation of crystalline silica that triggers a fibrotic response in the lung parenchyma. It presents as diffuse interstitial disease and clinical expression ranges from asymptomatic forms to chronic respiratory failure. Diagnosis is based on clinical history and radiological findings. There is no effective treatment, and once diagnosed, the patient must avoid all sources of occupational exposure.

In these guidelines, the clinical, radiological and functional aspects of silicosis are reviewed, and strategies for diagnosis, monitoring and classification of patients are proposed, along with recommendations regarding the occupational implications of this disease.
