The need for a regular comprehensive health surveillance on industrial workers.
The movement of people during some of their daily occupations and activities releases an amount of dust into the air. Even dust that has settled on floors and flat surfaces is made airborne by air currents. Of greater concern is the dusty environment caused by the operations within the workplace, such as handling of dusty materials, machining, cutting, drilling, milling, rock blastic and pounding. Fortunately, a lot of the dust is harmless except when present in high concentrations when it can cause some discomfort. At such levels it is termed 'nuisance dust'. However, some form of dusts are distinctly harmful, giving rise to impairment of lung function and pneumoconiosis (dust-induced changes in the lung).
