Introduction: Welding is an important component of industry in India. Welding workers are exposed to inhalation of fumes coming out during welding process and this welding fume inhalation has been associated with many respiratory problems.
Aims and Objective: To Measure the pulmonary function parameters such as forced vital capacity (FVC), forced expiratory volume during the first second (FEV1), FEV1/FVC and maximal voluntary ventilation (MVV) in controls and arc welders, depending upon the period of exposure of arc welders to welding fumes by using Spirometry, To compare FVC, FEV1, FEV1/FVC and MVV between controls and arc Welders and to give information to the welders about the side effects of Welding fumes on their health.
Materials and Method: This study was done on the 50 male welding workers with the age of 25-40 years working at local welding shops for 5-7hours/day, working during the last 5 years. FVC, FEV1, FEV1/FVC and MVV were recorded on a whole body Plethysmograph (Elite Dx model, med graphics, USA). The results obtained were compared with that of the controls.
Results: The exposure of welders to the welding fumes causes the significant decrease in lung function parameters like FVC, FEV1, FEV1/FVC%, MVV as compared to control groups.
