An epidemiological study of the risk factors of occupational diseases in coal handling plant of a thermal power station.

ABSTRACT

Anthropometry and morbidity profile of fifty randomly selected workers of coal handling plant at a thermal power station of West Bengal having at least five years experience were studied. The mean value of their age, duration of present job and Body Mass Index (BMI) were 34.8 years, 7.86 years and 19.24 respectively. As they were exposed to coal dust (Av. concentration 300-350 mg/M3 of air), warmth (Ambient temperature 40 +/- 5 degrees C), humidity (Relative humidity 80 +/- 5%) and noise [Av. 80 dB(A)], respiratory system was most commonly (72%) effected followed by greying of hair (5.6%), Cloth dusters used by some could not render any discernable protective effect. Addiction was also prevent (62%). Use of proper protective equipments (PPE) supplemented by adequate preplacement and periodic medical examination followed by successful rehabilitation were suggested.
