how much silica dust causes silicosis

Respirable silica dust long

Silica – breathing crystalline silica dust can cause silicosis a disease that can prove to be fatal in its severe forms Silicosis usually appears after 15-20 years of occupational exposure Symptoms are not always obvious so workers need to undergo a series of tests to determine whether there is lung damage As it progresses the illness can lead to shortness of breath fatigue or
