Abstract
The main objective of this work is to analyze and evaluate the risks in the activities and processes developed in a civil construction work focused on the sanitation area, through the improvement of the Preliminary Risk Analysis (PRA) integrated with the Ishikawa Diagram, seeking to reduce the subjectivity of the PRA technique, in addition to identifying and characterizing the existing risks in the activities performed by workers, the probability of their occurrence, the level and intensity of the risks, and also having the necessary recommendations for each observed risk. Daily monitoring was carried out at all stages of the executive process of the activities explored to identify the risks to be analyzed for the constitution of the PRAi (Ishikawa diagram integrated with the PRA). Based on the PRAi results, the incidence of physical, ergonomic and accident risks was observed. Based on this research, it became clear the importance of identifying the risks existing in the activities observed and the necessary protection measures to mitigate or even eliminate risks in the work environment, improving safety, quality of life, and, consequently, productivity.
