OBJECTIVES: The study was designed to assess the effect of wood dust on pulmonary system of carpenters. METHODS: The total number of 100 male carpenters age ranging from 18-50 years, more than one year work experience selected randomly from the wood industries in Quetta district, Pakistan. Data was collected by using self-questionnaire based on interview and Spirometric tests were carried out. Forced vital capacity (FVC), Forced expiratory volume over the first second (FVE1) and FEV1/ FCV ratio were observed and analyzed. To find statistically significant dif­ference between the mean of groups by ANOVA test (P < 0.05) was observed on post hoc analysis (Tukey’s multiple comparison analysis) by using SPSS 22. RESULTS:  The total 100 carpenters were selected and divided in to four categories of age groups; out of which age group 18-27 years were 55 (55.0%), followed by age group 28-37 years 19 (19.0%), age group 38-47 years 15 (15%) and age group 48 years > 11 (11.0%). The mean of percentage predicted for (FVC) the group exposed to wood dust for less than 5 years was 57.8, exposure group 5-15 years the value was 63.63 and in exposure group 15 years & > 59.12. The mean of percentage predicted for (FEV1) in less than 5 years exposure group was 58.77, in exposure group 5-15 years was 67.29 and in exposure group 15 years & > was 67.15. The mean of percentage predicted for FEV1/FVC in exposure group < 5 years was 94.04, in exposure group 5-15 years was 94.23 and in the exposure group 15 years & > was 89.74 %. CONCLUSIONS:  The finding of this study determined that the wood dust adversely affect the Pulmonary System and this damage is linked with the duration of exposure to wood dust. The study population related to the wood industries workers affected with the restrictive lung disease.
