Background: Carpenters are exposed to wood dust and other irritating chemicals during Work which can induce respiratory disorders. In this study pulmonary function tests (PFT) and self-reported respiratory symptoms in carpenters were compared with matched control subjects. Methods: The frequency of respiratory symptoms was retrospectively estimated in a sample of 70 Iranian carpenters using a questionnaire included questions on Work-related respiratory symptoms in the past years, allergy, type of irritant chemicals that induce respiratory symptoms, smoking habits and Working periods as a carpenter and 70 normal people from the general population as control groups. Pulmonary function tests including: FVC, FEV1, MMEF, PEF, MEF75, MEF50, MEF25, were also measured in all participants.Results: The most common syptomes among carpenters was cough during Work (56%) and sputom. The dust of MDF wood was fund as the most irritant factor and all carpenters Working with that showed some degree of allergy to its dust. The FVC was abnormally low (<80%) in 90% of carpenters and its value was significantly less than control group (P<0/001). Conclusion: Carpenter Work was associated with a high frequency of Work related respiratory symptoms particularly after exposure to irritating chemicals. PFT values were also significantly reduced among carpenters.
