Millions and millions of people are working daily in an atmosphere filled with respirable dust particles. Crystalline silica is an important dust particle which is generated in many occupations like stone carving, quarrying, sand blasting, shipping, ceramic industry, etc. The workers who are constantly exposed to the silica particle on a regular basis are more likely to develop occupational lung diseases like pneumoconiosis, chronic obstructive pulmonary disease (COPD), bronchitis, etc. These cause a decline in the lung functions. The purpose of this review article is to narrate the effects of occupational exposure of silica on lung functions. The spirometry results revealed a decline in forced expiratory volume 1 second, forced vital capacity, and ratio of forced expiratory volume 1 second to forced vital capacity. This reveals the need for proper education of the employees to take adequate preventive measures during working like wearing protective personal equipment, periodic screening, etc.
