This paper presents the results of research on the effect of hydrated calcium sulfate (phosphogypsum) on the mechanical properties of composite based on aluminum powder. The phosphogypsum used is a by-product obtained in the phosphate fertilizers industry, e.g., at the Gdańskie Zakłady Fosforowe "Fosfory. " The amount of phosphogypsum produced in Poland must be reduced due to the high costs of its storage and environmental protection. One of the ways to dispose of it is to use it as a filler in composite rods based on aluminum powder. The amount of phosphogypsum added was 2% and 5% by weight in relation to the aluminum powder's weight. The filled composite was subjected to strength tests to show whether phosphogypsum improves the mechanical properties of aluminum rods. Based on the results obtained, it was revealed that phosphogypsum used as a filler causes similar changes in the mechanical properties as mineral fillers described in the literature. Based on analyses of market potential, it can be easily assumed that there is a significant demand for the results of research on the use of phosphogypsum. The end of the article summarizes the discussed issue, emphasizing that solutions are sought for the use of phosphogypsum.

Abstract. The article presents a developed Analytic Platform -Direct Safety, which can be helpful, especially for small enterprises, in determining own policy in the field of occupational safety. Small companies need indicators, on the basis of which they could anticipate and undertake actions aimed at weak sides of the occupational safety. The developed application provides means for analysing a series of aspects, variants and compilations between particular data. One can conduct an analysis anytime, arbitrarily changing selected criteria. The developed tool allows a complex analysis of collected data, considering all values obtained during the analysis of the company's occupational safety state. The article describes the possibilities of the developed Analytic Platform -Direct Safety, on the basis of an analysis of results of the research in the field of measuring the level of the occupational safety culture conducted at a small manufacturing company

The following paper presents an IT tool for aiding assessment of a safety culture level in an organization in a form of an application, providing fast and easy way to analyze data obtained from questionnaires. Traditional data analysis often turns out to be time-consuming and labor-intensive. To make the process faster, more detailed and to find all the possible links among all the available data there is a need for an IT tool. The presented application has been developed with publicly available and completely free tools and technologies. It is a complete piece of software, fully flexible which can be modified or equipped with new functions (modules). The presented solution eliminates the time consuming process of “copying” data from paper questionnaires, and allows to get information about the safety culture level right after adding a questionnaire to a questionnaire database. The presented tool can function as a mobile questionnaire which can be used in any place with Internet access and to fill it in only a browser is required.
