Abstract
In glass and ceramic industries, mineral silicates are widely used. During transportation, crushing, grinding, classifying, screening and mixing operations, a lot of fine dust is released in the atmosphere in absence of suitable control. Some manufacturing operations such as crushing and grinding make intolerable noise. During firing, baking or fusion of materials in kilns or smelting furnaces at temperature averaging 1000° to 1700°C, excessive heat is generated at the working place. Due to inhalation of a significant amount of fine dust, and constant exposition to intense sound and thermal stresses over a long period, several problems of health hazard arise. For identifying these problems and taking preventive and control measures against dust, noise and heat stresses, the working environment must be evaluated. The present article enumerates the sources of pollution, nature of pollutants, their effects, as well as standards for permissible limits of pollutants in the occupational environment, and suggests some preventive measures.
