Prevention and Prognosis


Limiting exposure to harmful dusts is one of the most efficient strategies to prevent silicosis. Air quality and dust concentration in the workplace has to be monitored. Routine chest radiographs and spirometry can be used to monitor workers, and may help to identify early disease. Avoidance of smoking is a must. Efficient smoking cessation efforts should be encouraged.


Patients with simple silicosis may have no symptoms and may remain stable for many years. The prognosis of accelerated silicosis and acute silicosis is poor. Complicated silicosis shows gradual worsening of symptoms; lung function deteriorates and disability increases.

Silico-proteinosis is a fatal pulmonary disorder. The clinical presentation at the time of diagnosis is a predictor of prognosis.

Hi Sincerely seeking some professional advice here. I have been exposed to an incident of inhaling silica dust for some 2 hours at a quartz, granite, marble polishing and grinding foundry [as I was tasked to select marble for our new office renovation]. The dust concentration in the enclosure is strong in my opinion (air is of a dusty white fog with strong smell of the stones). Now I noticed phelgm and mild coughing. Do I need an X-Ray examination for symptoms of silicosis? Also, since silica gets retained would anyone who inhaled silica dust, even if of a one off incident eventually develop symptoms of silicosis? Thank you
