Three hundred and forty-two male workers of a thermal power plant were screened by spirometer. The mean FEV1, FVC and PEFR were found to be 2.33L. 2. 74L and 374 lit/min respectively, significantly lower than normal predicted values (p<0.001). The Parameters were found to be much reduced in smokers as compared to non-smokers. FVC and FEV1 were found to be much lower in coal unloading section (2.17L and 2.5IL) as compared to other sections. Spirometry was found to be an effective and simple screening method for detection of ventilatory impairment in exposed workers.
