Improving Occupational Safety Management with the Use of Human Reliability Analysis Methods

The aim of this work is to review the basic issues and problems related to the analysis of human reliability in terms of the possibility of using the methods functioning in this area to improve occupational safety management. Methods of human reliability analysis (HRA) are related to the prediction and assessment of system failures, which are the result of incorrect actions or omissions by a human, and not the failure of a physical element in the system. The paper presents the significance of the problem of human reliability from the point of view of accidents; describes HRA as a process with three main components; characterizes human errors using various criteria as well as discusses the generations of HR analysis and evaluation methods, including factors influencing the performance. The basic guidelines for the selection of methods for reliability analysis were also presented in terms of their possible use for improving the health and safety management system.
