Occupational health is an area of work in public health that promotes and maintains the highest degree of physical, mental, and social well-being of workers in various occupations. Amongst various factors, a major reason for atmospheric pollution is an increase in the number of vehicles, as there is a rapid trend towards urbanisation. This has resulted in increased consumption of petrol/diesel as well as increase in the number of petrol pumps across the country. Hence, the researcher wanted to evaluate the changes in pulmonary function parameters of petrol filling station employees in the capital city of India using rehabilitative measures to create awareness and overcome the respiratory morbidities. Thus, the present study was undertaken.
