The aim of the article is to point out the dangers arising from the properties of plastic dust and what influence its properties have on the origin and course of the explosion. The present project analyzed the sample of polyethylene dust,by-product of granulate production and storage. The explosion tests were performed on containers of a similar shape to those found in a plants. By examining the properties of plastic dust and its behavior in the event of an explosion we have observed that the risk of explosion in technological equipment can not be underestimated. Knowledge about explosiveness of dust samples will be used in comprehensive safety solution of a particular technological node.

The article summarizes a short review of the literature focused on safety in the field of alternative energy sources. With an increasing orientation towards sustainable and renewable energy sources, new technologies will come to the fore. These facts must be demonstrated in occupational health and safety. Several studies focused on alternative energy sources are mentioned and show the trends for the future. Especially in the area of hydrogen and battery technologies, systems should pay attention to acquisitions as a normal part of our lives. Safety research is essential for the acceptance of cleaner, efficient, and sustainable future.

During the process of electrostatic powder coating in coating booths, there is a probability of the risk of explosion. Compliance with the normative requirements referred to in the legislation in force minimize the hazards associated with the risk of explosion. This article focuses on the analysis of the current security level of coating booths in terms of the risk of explosion in relation to the lower explosive limit of the selected powder paints.
