This research was carried out in four joineries located in the Federal District of Brazil, with the objective to analyze the exposition of the workers of joineries to the ambient factors - thermal comfort and illumination and to supply subsidies for an organization or ergonomic reorganization of the work, aiming the improvement of the health, security, well-being, comfort, satisfaction, quality and productivity of the work. The machines chosen for the analysis had been the buzz saw of stand, tupia, float, horizontal wimble and sander of brace. The data were collected along the working period, through climatic measurements of the illumination and work environment. Analyses of variance of the climatic conditions and illumination were performed in order to verify if there were significant differences between the values collected. The results indicated that the joined average Índice of wet bulb and globe temperature in the companies was 21.4 °C, which allows a continuous work during the 8 h of the day, according to NR 15. Some places of work presented deficiencies with relation to the illumination, according to NBR 5413/92, tupia (467 LUX) and horizontal wimble (390 LUX) in company 2, buzz saw of stand (179 LUX) and sander of brace (172 LUX) in company 3 and tupia (339 LUX) in company 4.
