About small-scale asbestos mining and milling facilities and 33 large - scale asbestos manufacturing plants, 17 asbestos-cement product manufacturing plants and 16 other than asbestos-cement product plants are situated in India. The present study reveals the exposure of commercial asbestos chrysotile in the occupational as well as ambient air environment of the asbestos-cement AC sheets industry using membrane filter method of Bureau of Indian Standards BIS. The fibre concentrations in 15 samples collected in the occupational environment at ingredient feeding site, sheet-producing site, fibre godown were 0. Morphological analysis of samples, further under phase contrast and polarized microscopy indicates the presence of chrysotile asbestos, which acts as carcinogen as well as co-carcinogen. A clinical examination of exposed subjects reveals that there was no case of clubbing, crepitation, ronchi and dyspnea on exertion; however, obstruction and restriction were The study revealed that chrysotile asbestos is emitted in the occupational as well as ambient environment that may cause adverse health impact.

When mixed with cement to produce roof tiles and water pipes, the products are high quality and economical. Dusts or airborne fibres including glass fibre, synthetic fibre, chrysotile fibre, stone dust, gasoline fume, exhaust fume, all are dangerous, if workers inhale and are exposed to them for a long period of time.

However, the processing of chrysotile fibre as a raw material in manufacturing factories is properly controlled and thus, poses no risks to workers. Once the fibres are covered by cementous slurry, they are locked-in permanently and cannot escape. Typical test results of air sampling show that fibre concentration is around 0. This is far below the level of 0. There will be no risk for workmen or carpenters if they follow properly recommended work practices while installing or fixing roofing sheets.

Asbestos is the generic term for a group of naturally occurring fibrous minerals with high tensile strength, flexibility, and resistance to thermal, chemical and electrical conditions. Asbestos fibers are of high-tensile strength, flexible, heat and chemical resistance, and good frictional properties. Cement is the most essential raw material in any kind of construction activity. Ceramics also known as fire clay is an inorganic, non-metallic solid article, which is produced by the art or technique of heat and subsequent cooling. Limestone is a sedimentary rock, mainly composed of calcium carbonate CaCO3. It is the principal source of crushed stone for construction, transportation, agriculture, and industrial uses.
