    The range of tasks in shoe repair is wide and there is little researched or published information on the subject. The purpose of the study is to respond to the lack of teaching and training material for occupational safety by identifying the risks associated with work tasks and phases according to the experience of the shoe repairers. The study also takes into account the machinery and functions related to the machinery used for work tasks and phases. In addition, the aim of the research is to identify the factors present at a shoe repairers’s work from the perspective of the safe execution of the work. Based on the research results, the sections that should be researched and addressed in the implementation of the teaching and training material to be compiled in the future will be identified. The study was conducted as a quantitative questionnaire survey in the spring of 2022. A web-based questionnaire was developed for the study and distributed to shoe repairers with the assistance of collaborators. A total of 47 respondents participated in the survey, most of whom had long work experience in the field. The research results were processed by quantitative methods using statistical analysis methods. The results of the study show that the shoe repairers didn`t experience more than moderate risks associated with work tasks and phases. The research results highlighted the risks of operations related to the machinery and machine-related functions. Based on the results, distinct work phases and machines or machine-related functions required for implementation were identified, which should be taken into account when developing material suitable for training. In addition, teaching and training materials should draw particular attention to the maintenance and operation of working equipment and machinery.

    The aim of this current study is to increase awareness and to provide insight into the human psychological constraints and their contribution on hazardous situations at work as well as to provide new tools for the further development of occupational safety. Interruptions at work are common and may result in hazardous situations. The accident risk caused by interruption is often based on the employee's work experience converted into automatic cognitive processing. We know very little about the impact of interruptions on the automatic processing. In addition to other adverse effects it may cause, interruption may result also in cognitive bias. Interruption may lead to a situation, where we falsely believe that what has been started, has also been done. The case study used data that has been screened in international and national fatality investigation databases. The selected cases were analysed by applying a cognitive analysis of interruption method. From the available literature, research and analysis of the cases, it appears that the automatic cognitive processing is very vulnerable to interruptions. Vulnerability was manifested especially in situations where the attention demanding controlled processing broke off automatic performance. Automatic processing can also lead to situations with significant risk when unexpected change in the environment is occurred or if environmental conditions no longer reflect the current automatic cognitive processing. In automatic work process, which includes subtasks operated always in same specific order, case analysis gives a clue to the emergence of cognitive bias. This is manifested in a situation where already started subtask or part of the started work, which is perceived as a whole, is interrupted. However, more research is needed to determine the exact mechanisms behind this phenomenon. The damage interruptions might cause during an automatic work performance can be reduced by the use of external cognitive tools to increase attention and to ensure situational awareness especially when disengaging and/or resuming the original task and by the development of technical security solutions.
