A number of workplaces where the employees work under noxious environment exist within the thermal power plants. The infliction of the working environment has more or less detrimental effect upon the personnel exposed depending on the existing noxes’ toxicity, the concentration, exposure duration, and constitution of the subjects exposed. At present, a number of specific measures have been taken in the power generation sector in order to limit or eliminate the noxes, with a view to prevent the employees to fall ill, however these measures gave not the expected efficiency. The survey of the workplaces has aimed at transforming the risks into either non-risks or lower risks through the cognition of the noxious factors (and the risks due to them) existing in the zone of the workplaces and through the cognition of the measures specific for the individual and collective protection, and, the last but not the least, the cognition of the measures required to reduce, eliminate and prevent them. Identification of the places with a high noxious level and the preparing of the technical-organisational solutions for the improvement of the physical and chemical noxes exhaustion and elimination, including also the impact of their application financial costs represent all factors of major importance for lining up the occupational noxes levels with the national and European standards. This paper describes the evaluation of a real situation by help of the modern methodologies for the identification and monitoring of the physical and chemical noxes from two Romanian thermal power plants, the analysis of the health condition for the employees exposed to such physical and chemical noxes and it establishes, in the end, the risks of the occupational exposure. Further on, the main technical solutions for the diminishing or elimination of the occupational noxes at the workplaces from the thermal power plants are described. These solutions consist of various types of phono-isolating and phonoabsorbing cabins intended for the reduction of the noise level; ventilation systems of the honeycomb type, modern niches made of corrosion resistant materials for the reduction of the chemical noxes, use of the non-asbestos sealing materials. Through the implementation of the technical solutions for the attenuation of the occupational noxes a major desiderata is provided for lining up with the Regulations of the European Community concerning the increase of the life quality in the workplaces from the energy industry.
