A major difficulty in establishing the program of action or devices to prevent the risk of incidents and accidents are the occupational and environmental records of deviations and its research into the causal connection. The proposed work aims to analyze deviations of the operation, process and maintenance of industrial facilities that impact on the environment. These deviations are observed and recorded to investigate the failure mode and recommending ways to mitigate its impact. The steps of this methodology are: (1) registration of deviations from routine (database); (2) the causal analysis and fault tree construction; (3) definition of the logical operator and calculation of probability; and (4) investment analysis to mitigate impacts. This technique was applied in the case of oil spill from machines in a chemical industry and environmental impacts. An understanding about the relation between deviations, causes, and top event allow quantifying the probability, set management actions, and/or designing technical devices economically viable.
