Abstract: The labour risks evaluation techniques are carried out using several methods, through the application of normative methods applying the execution of the parameters associated with the measurements of the men's health damage thresholds. Basic security principles are nevertheless not taken into account, which enclose the good practices experiences in high-requirement security and availability industries. Objectives: The purpose of this article is to propose a method attending on the defence in depth in order to evaluate the noise labour risks in the Thermal Power Station (TPS) of 100 MW. Material and Methods: In order to explore the elements considered in the evaluation of the noise labours risks, interviews to technicians and specialists in labour security and health were taken. It was carried out the consultation to specialists in order to specify the elements that should be part of the security aspects according to the nominative method. The evaluation of the labours risks for noise together with the proposal were also carried out according to two methodologies prior employed. Results: three methodologies were used. It was determined that the noise generation is not a significant aspect to keep in mind for the methodology 1. For the methodology 2 it was demonstrated a dispersion of the noise level with stable tendency to the maximal values in determining areas according to the Noise Cuban Norm, while for the methodology 3, the security aspects negatively evaluated for each step, are those which require to take corrective measures implemented to modify the negatively-qualified items to positive in order to raise the security level. Conclusions: The evaluation using the depth security levels applied to the labour risks allows to estimate an analysis with the process approach, that allow not only to esteem the relative contribution and its causes but to resolve them in a short-term period.
