ETA AND FTA METHODS AS AN TOOL IMPROVING OF SAFETY MENAGMENT SYSTEMS IN THE COMPANY

Abstract

The article analyzes the impact of the selection of the hazard identification method on the accuracy of the occupational risk assessment. This leads to more effective security management in the enterprise. Explained examples of explosive gas explosions and overheating of the machine show the relationship between the identified different types of hazards (causes) leading to adverse events occurring in industrial conditions. This analysis was made using two selected methods: FTA (fault tree analysis) and ETA (event tree analysis). Both the analyzed examples take into account technical hazards and human errors (human factor). The cause-effect relationships of hazards are presented in the form of diagrams in the drawings. In addition, the methods of hazard identification used for the analysis were compared with their scope of use.
