CONCLUSION
The mean PEFR of study subjects was less than that of the control subjects in each sub group of age, height, weight and BSA and these results were statistically highly significant. The decrease in PEFR in carpenters was probably caused by a continuous occupational exposure to wood dust, which had caused an adverse effect on their respiratory functions. His/her working conditions are important for a person’s respiratory health.
---- Mostly, all the carpenters work in confined spaces without protective devices. In order to prevent the ill effects of wood dust on the respiratory health of carpenters, we suggest a medical observation which includes pre-employment medical check-ups, provision for a good ventilation at work place and encouragement on use of personal protective equipment like masks. Further regular lung monitoring should be done to detect any ill effects on respiratory system at an early age and to prevent spread of the disease.
