Análise de riscos em parques eólicos: um estudo de caso

Abstract

This study addresses issues related to job security in the wind energy sector. It analyzes the activities associated with the construction of a wind farm and identifies the specific hazards to which the employees are subject since the execution of the accesses until the assembly of the towers. The fact that wind energy is considered "green" and good for the environment does not necessarily mean that it is good for the health and safety of the sector employee. Throughout the different stages of the construction of the wind farm, employees may be exposed to dangers that could cause death, serious injury or health problems. This study aims to analyze the risks in the construction of a wind farm using a Risk Management tool, What If, to construct a wind farm in order to make a survey of the risks that employees are exposed to. In order to achieve this objective, four main activities were chosen in a project in the backlands of Bahia: earthworks, concreting, electromechanical works and assembly of machines. The choice was based on the greater complexity of these activities, which, consequently, become activities with greater potential to generate work accidents. As a result, we obtained a long list of possible risks that employees are exposed and also the causes and consequences related to these risks, for example in the Terraplanagem activity, some of the possible risks are: tipping, trampling and collision of vehicles and the main mitigating measures are: limiting the speed of vehicular traffic, signaling of the work area, training and use of PPE. With this, it is observed the importance of the application of What If, because it was possible to identify the risks and, thus, to prevent and minimize the accidents at work.
