Abstract

Food safety means all the conditions that have to be met and actions that have to be taken at all stages of food production or sales to protect human health and life. Studies have demonstrated that organic food is considered by consumers to be healthier and safer than conventional food produced by means of intensive farming methods. In this context, the interest in organic food among both consumers and distributors is increasing. This means that there are many factors determining organic food production. Among them are those related to competencies that affect product safety, which represents a guarantee that the enterprise will achieve market success and is one of the sources of competitiveness for such enterprises.

Therefore, the aim of the study was to present assessment of soft competencies of laboratory employees by their immediate superiors. The problem was identified more closely as a case study of the corporation that produces organic foods, whereas assessment of competencies was compared to the specific features of the food sector the enterprise operates in, with the examples of the branches located in Poland, the Czech Republic and Romania.

Abstract

The purpose of the publication is to determine the level of consumer awareness regarding the knowledge of quality marks and food safety awareness in the aspect of purchasing decisions. The research covered a group of 51 respondents who were residents of the Silesian Voivodship. On the basis of literature research and analysis in the field of food quality and safety, the following hypothesis was formulated: By using generally known management methods, we can determine the degree of consumer awareness in terms of quality labels and food safety in the aspect of purchasing decisions. The research was conducted on a quarterly basis in 2018 based on a questionnaire (CAWI - Computer Assisted Web Interview). The results of research and their analysis have shown that consumer awareness regarding the awareness of quality marks increases, however, there is still a great need to build consumer awareness regarding the existence of quality marks and information that they provide to the consumer in terms of both quality and food safety. Research has shown that consumers are aware of the quality marks existence, but their knowledge about familiarity is still too small. It was shown that consumers, when making purchasing decisions, pay attention to product quality, price, quality certificate and ecological certificate. The factor that determines the safety of the product according to consumers turns out to be its composition. Consumers showed in research that they will not buy a product that has palm oil, sulfur dioxide, glucose-fructose syrup and aspartame.

Abstract

Occupational health and safety (OHS) management is a cycle of decision-making processes, many of which are in fact multi-criterion processes in nature. Therefore, it is important to look for and develop tools to support decision-makers in their actions aimed at improving work safety levels. The objective of this paper is to propose and verify the fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method applied to compare and assess the ways OHS management systems function in different companies. The fuzzy TOPSIS method has already been used for a number of years in assessments of alternative solutions in many different areas, but the application that uses ordered fuzzy numbers is quite original in nature. It is especially beneficial to use the fuzzy approach in OHS management systems, as it makes it possible for experts to assess different criteria using most frequently used linguistic variables. The adopted approach was verified in the study of OHS management systems in four furniture manufacturing companies. Assessment criteria were requirements of the PN-N 18001: 2004 Standard. Thanks to the ordered fuzzy TOPSIS method, the analysed OHS management systems were streamlined from the point of view of 24 assessment criteria, and the best and the worst functioning system was identified. The approach presented here may constitute a significant tool for improving OHS management systems.

Abstract

Recent years have shown increased interest in the use of glass structures in the construction industry. Investors value qualities such as aesthetics and the good environmental resistance of glass. It has become commonplace to use glass not only to construct façades, but also in horizontal partitions (floors, building coverings ) and in such elements as protective canopies, passageway screens or fire barriers. Such extensive use of this building material has been made possible by the development of technology for manufacturing glass with improved strength properties, in particular, toughened and laminated glass. However, glass has some disadvantages as a building material – first of all, low tensile strength, impact strength and point load compressive strength. The use of glass with improved strength properties minimises these defects to a considerable extent. Nevertheless, it sometimes happens that glass structures crack or lose their aesthetic value. This results from errors made during the design stage as well as during the construction work on the structure. Based on an “in situ” study and the literature on the subject, the article identifies risks associated with the use of glass elements, in addition to analysing their causes and possible effects. Examples of real elements in the course of their use are provided in order to illustrate the factors under analysis. Moreover, the article includes recommendations linked to the safe usage of glass in the structure when discussed against the background of assembly errors.

Abstract

The most typical situation which could be present during hydraulic system operation and maintenance have been analysed and classified to help understand its correlation with safety. Finally each of specified danger situation during system operation and/or maintenance contents rules and warning advice to avoid safety risk.

Abstract

Assurance of the supervised conditions in all processes affects directly both products and users safety and environmental influence. ISO 9001 and ISO 14001 standards in Operation point require from organisations to implement and control the planned processes by establishing processes’ criteria, assuring the supervised conditions and verifying processes’ conformity. Moreover, in Planning section it is required to plan the processes with the consideration of quality and environmental risk. Therefore research on the practical solutions of operational planning and control in the production processes are of the crucial meaning, especially from the perspective of the integrated fulfilment of the requirements. That is why the value of the paper is being constituted by the authorial methodology of identification of the key-operational criteria, including integrated risk assessment, using the computer support and being a starting point for assurance of the supervised conditions in the key-processes of high risk. The worked out methodology has been implemented in the processes of performance and completing the stirrups, which quality is of the huge influence on the work safety of the mine roadway supports in the mine workings. The aim of the analysis was to identify the operational parameters in the stirrups technological process, to estimate their meaning and to point at the key operational criteria from the point of fulfilling the quality and environmental requirements. Practical implication of the proposed methodology can be applied in case of any organisation which wants to improve the realised processes ensuring the computer supported supervised conditions.

The aim of the paper was to analyze gaps in expectations concerning services and the perceived level of meeting these services. The paper has a form of a case study.

Abstract

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.

Abstract

Workers' safety in the workplace depends on the compliance of both employees and the employer with applicable regulations. The EU member states in internal law contain regulations in line with EU directives in this area. The author of this study decided to examine whether compliance by the employer with health and safety provisions is an element motivating employees to take up employment. he law applies to both employees and employers, but their content is not affected by any of the parties to the employment relationship. The purpose of the article was to answer the question whether compliance by the employer with health and safety at work rules is an element that influences the employee when making a decision about taking up employment. The method used was the diagnostic survey method and the survey tool. The research was conducted in 102 facilities-enterprises in the Silesian Voivodeship employing at least 20 employees. The respondents were employees within the meaning of the Labor Code who declared knowledge of basic regulations in the field of occupational health and safety. The unambiguous lack of impact of compliance with the health and safety at work regulations by the employer on the decision on employment was indicated by 29.3% of respondents, while 60.8% of all respondents declared such an impact. Among the surveyed employees there was a group of undecided people,
