The construction industry presents great contributions to the development of the country, with a view to generating employment, income and indirect relations with other productive sectors. However, it is possible to observe in this scenario a series of factors that limit the breadth of the segment, among them, the lack of investment for the renewal of processes and the lack of adequately trained professionals. Disregard for professional training becomes a strong threat due to social and financial expenditures, resulting from social security pensions, fatalities and production losses, which are associated with ergonomic risks and the occurrence of accidents. Thus, the objective of this work was to analyze the ergonomics of employees in construction sites in the municipality of Pau dos Ferros/RN. For that, questionnaires, on-site visits and photographic records were applied in five works in the city of Pau dos Ferros/RN. The OWAS method is also used to determine the levels of ergonomic risk in the identified activities. It was found that in the city of Pau dos Ferros/RN, this segment is marked by unskilled labor in view of the low level of education and the length of stay of workers. Regarding the ergonomic factors, it is observed that the main activities affected are the application of flooring, excavation and cutting of hardware. The main factor that impacts these activities are the adoption of inappropriate postures, portrayed by the continuous curvature in the back and flexed lower limbs. Another aspect to be pointed out are the physical efforts made. The lack of ergonomics in work environments manifests itself in the form of pains and other discomforts to civil construction workers, with the main inconveniences associated with pain in the spine, lower and upper limbs. The pauses point as a positive factor to the ergonomic analysis, however in one of the works there is only a break in a work shift, according to some collaborators reports. It was also observed the neglect with preventive activities, such as the practice of stretching and physical exercises.
