Unless a doctor knows that you work around silica, the disease can go undiagnosed. Symptoms can come on gradually and resemble other problems, such as smoker's cough or ordinary fatigue. Workers who are exposed to silica dust may want to consult a specialist in this area. Exposed workers should have an x-ray every two or three years and a lung function test once a year. Medical exams are helpful but cannot be relied upon as a primary protective measure.
Preventive measures are essential because the disease is often well advanced before detection.
The key to preventing silicosis is to control the exposure to free silica. Full employee cooperation is a must for effective prevention. Where engineering and administrative controls are not feasible, it may be necessary for a worker to wear a dust make or respirator. If a respirator must be worn, it is essential that the right type be used and that the respirator be fitted correctly. If a respirator program is required, workers should be examined medically to ensure that they would suffer no harmful effects from regular respirator use.
