Opis:
The paper deals with the issue of occupational health and safety in a metalworking manufacturing organization. Hazard and threat have been defined when cutting metal materials with a band saw. We assessed the risk by an extended point method, where we determined the risk rate values. In most cases of sawmill work, we found a “moderate” or “negligible” risk. The highest, ‘serious’ risk we found in a possible electric shock. In this case, we have also taken the necessary actions. As a precaution, we have also proposed safety measures for other threats.

Opis:
The quality of refractory materials plays an important role especially in high temperature processes. In case of violation of qualitative properties of refractory materials, the safety of the use of the technological equipment in which these materials are used is compromised. The requirements on the quality of refractories and their properties are now high, as their operating life should be as long as possible. The aim of the article is to point out the quality of refractory material in contact with corrosive media, to analyze the technological factors that affect the quality and safety of technological equipment. An analysis of the refractory material, as well as the analysis of the melt was performed. Subsequently, an experiment was realized, which was evaluated by macroscopic analysis and chemical analysis. After the experiments, we found that the melt had penetrated the masonry and consequently created corrosion layers in the masonry. These layers have affected the life of the material and reduced the safety of the technological equipment in which they were used.

Opis:
When using various types of services, the customer may experience positive or negative situations, incidents. These incidents may affect the customer's satisfaction or dissatisfaction. Therefore, these incidents can be a source of very valuable information for the enterprise about the quality of the services it offers. The problem, however, is their analysis, because such incidents can affect different aspects of the service, but also, as mentioned earlier, can have a positive or negative impact on customer satisfaction. The Critical Incident Technique (CIT), often mentioned in the literature, can be used for such an analysis. With this method, it is possible to isolate situations that are typical of the negative and positive feelings of the customers, as well as to determine the frequency of their occurrence. The purpose of the papers was to analyze the quality of services offered by the chosen catering enterprise with use of CIT. The research took form of a direct interview with customers after delivery of the chosen service. Data obtained on this basis was analyzed: all incidents were first divided into groups and categories as well as positive and negative incidents, and then statistics for individual categories were presented. This research allowed to indicate the strengths and weaknesses of the research service, but at the same time to indicate the areas of potential improvement.

Opis:
Technological progress has brought a large amount of complex machinery into the work processes, which represents a potential source of serious injuries, accidents, or breakdowns. The aim of this paper is to follow new trends in the FMEA and their use in our study. We have chosen the Turning Machine Doosan V-Puma Doosan PUMA V550R Machining Centre with manufacturing diameters and mechanical machining operations. We have created the FMEA team, which participated in the entire evaluation and analysis. We identified possible failures and causes of failures in the given operations. We applied the conventional PFMEA and identified the RPN risk number. We also used DEMATEL model. Using DEMATEL matrices, we identified a binding between the individual failures and the causes of the failures. Some failures will become the main cause of other failures and the causes of the failures; some arise as a result of other failures or causes of failures. Finally, we evaluated the applicability of individual methods and models. By the DEMATEL model we clarified the significance and bindings between individual failures.
