ABSTRACT This paper presents an environment evaluation into a naval metallurgy workshop, about the heat exposure conditions and the indoor air circulation. This naval metallurgy is localized in a building of a Naval Yard in Rio de Janeiro city. In this paper there are propositions about natural and artificial ventilation systems of the industrial building. The objectives of these suggestions are to make improvements about the workmen thermic stress. These suggestions considers too the air quality conditions, in relation to the workmen health and environment confort. It was essential a participation into the environment metallurgy workshop. The analysis includes too the air temperature and humidity measure. The thermic evaluation attended the Regulation Norms of Safety and Employment Medicine. As well as, the recommendations of ASHRAE - American Society of Heating, Refrigerating and Air-Conditioning Engineers, about natural ventilation systems in metallurgy work were considerable too. PALAVRAS-CHAVE heat, thermic stress, risks control.
