Silicosis is a potentially fatal, irreversible, ubrotic pulmonary disease that may develop subsequent to the inhalation of large amounts of silica dust over time. In most circumstances, silicosis only develops subsequent to substantial occupational exposures. The disease has a long latency period and may clinically present as an acute, accelerated, or chronic disease. Inhalation of quartz-laden respirable dust is known to induce such irreversible lung diseases as silicosis and lung cancer. Patients with silicosis are known to develop not only pulmonary disorders but immunological complications too, such as rheumatic arthritis, systemic sclerosis (SSc), and systemic lupus erythematosus (SLE). Currently, no cure or effective treatment is available for silicosis. The basic goal of any safety program should be to prevent the formation and escape of dust. A variety of federal and state agencies have initiated strict regulations aimed at preventing the development of silicosis in certain workers. These regulations generally emphasize adequate ventilation on job sites and limiting the amount of time workers. Systematic studies undertaken in various countries have established that inhalation of silica-laden dust beyond certain limit, commonly expressed as Maximum exposure Limit (Mel), may cause the disease. Although the MEL is adopted for assessment of heath risk of miners, some studies in recent times tend to indicate that one has to look beyond physical mass of silica in assessment of risk. Such factors as particle size, presence of other minerals, genetic disposition, hereditary linkage and physiological state of miners play a significant role in the development of silicosis. The present papers develop our understanding on silicosis based on the above factors and formulate a scheme to take preventive measures to keep the disease off.
