This research was developed in joineries in the south of the Espírito Santo State (Brazil) and aimed to quantify the vibrations transmitted to workers system hand-arm by the machines in the activities of furniture production. The data were collected by using an accelerometer model NK 20 and a meter of vibration model NK 300. The vibration was measured in agreement with the three orthogonal coordinates defined in ISO 5349-1 and explained by the ME Good Practice Guide HAV, following the orientations of Directive 2002/44/ EC of the European Union. The data were submitted to variance analysis in the entirely casualized experimental design. The averages of the machines were compared by Scott-Knott’s test at 5% probability. The smoother presented the largest vibration index in the orthogonal coordinates (fatigue area) and the sander the smallest vibration indexes (comfort area). The statistical analysis of the averages showed that a good correlation exists between the classification models and the one of analysis of the vibration indexes.
