Abstract
Live working (LW) is a complex and of high organizational requirement process. It requires the interaction of all actors in the process, from the beginning to the end, and therefore there is a great need to determine the security rules that are fundamental to minimize the occurrence of accidents related to electric risks. The main objective of this study was to make a risk assessment and compare the results obtained between the different methods used. In order to accomplish this study, it was necessary to monitor on the spot some works in LW, to be able to carry out a risk assessment as close to reality as possible. This risk assessment was performed based on three different methods: William T. Fine, NTP 330 and the method developed and used by the company, and 119 risks were evaluated. Although different types of risks have been considered, those that pose a greater risk to the health and hygiene of the workers are: “Live Working” and “Work at Height”. In all methods, these tasks represented the highest level of danger and therefore require more attention. Considering the risks that presented a higher level of risk, they should be monitored systematically and require urgent intervention to minimize the consequences.
