Abstract The objective of this study was to investigate the relationship between the use of masks, respiratory symptoms and lung function among coal miners. Subjects consisted of 395 miners aged between 28 and 42, exposed for more than five years to coal dust and whose pulmonary radiograph was classified 0/0 according to the 1980 ILO international classification of pneumoconiosis. Methods included administering the European Coal and Steel Community (ECSC) questionnaire, evaluating cumulated dust exposure and conducting lung function tests. Four groups were determined according to their degree of mask use. It was found that the prevalence of respiratory symptoms was not significantly linked with the degree of mask use. However, the proportion of miners with chronic bronchitis was lower among miners who had a high degree of mask usage.
