This work is a intend to evaluate quantitatively the airbornes produced by activities at civil construction on which the construction sites workers are exposed. It identify the necessity of implementing programs to reduce negative impacts in the worker' s health. It also intend to classify and identify some of the principal situations and activities of civil construction wherein actually there is most presence of the silica in dust. The study was conducted in several construction sites in Rio de Janeiro. In the field research was determined the respirable dust concentration with dust gravimetric bomb, filtering system (filtres, filtre-holders and holders) and from size particle system (ciclone). The samples analysis was performed in laboratory to determine the quartz by Fourier transformed infrared spectrophotometry (FTIR). This work demonstrates that the development of Environrnental Hazard Prevention Program is part of the most health prevention field and workers integrity, and must being articulated with the Medical ControI Program of Occupacional Health.
