High-energy liquid jet technology — risk assessment in practice

Objectives: The contribution deals with a risk assessment in practical applications of the high-energy liquid jet technology from the point of view of the risk identifi cation, estimation and evaluation. Materials and Methods: Differences between three different types of workplaces are highlighted and analysed - the indoor, the outdoor and the research ones. Theoretical analyses are supported by particular application of the method for the risk assessment in the Laboratory of Liquid Jets at the VŠB - Technical University of Ostrava. This laboratory is primarily oriented to research. Nevertheless, the conclusions can be used also for predominantly commercial workplaces. Results: Some new considerations and evaluations concerning health and safety are presented. Conclusions: Failure Mode and Effect Analysis (FMEA) procedures were applied and their limitations in risk assessment of water jet-based technologies are explained.
