The article presents the advantages of the fault tree analysis method as a tool to support the process safety management in the enterprise. The article presents features of the fault tree analysis method as a tool for better security management in an enterprise. Cause and effect relationships between events in the fault tree schema on selected examples were examined. Indirect and direct causes of accidents and failures in the enterprise have been identified, including human errors (human factor).
