The improvement of human performance and safety has been the subject of constant research, considered fundamental in the role of organisations seeking excellence. For those industries involved with high technological risk, such as the oil and gas segment, it is due to the realisation that control measures efforts have been researched without taking into account the different levels of occupational risk, situational aspects of organisational culture, components of safety control measures, among others. Among these findings are that human failure has been pointed out as a significant share of root causes of unwanted events, led in industries by the "human factor". Among the "human factors", risk perception has been incorporated into research as a goal to better understand the interaction of the man-machine-organisational system set, so that this interaction has acquired great value for the inclusion of a safe process, no longer being seen in isolation. The research covers the element of perception as something inherent to the cognitive capacity of the worker and attributes the existing gaps to the set of organisational factors.
