The paper deals with the topic of hazards and safety at work. The first part of the paper describes the cement production process. The great advancement of technology in the construction industry results in an increase in the production of construction materials, but at the same time brings an increased risk of adverse events. Accordingly, the development of new technologies and production processes requires constant education of workers who perform various procedures in the production of construction materials. The focus of work is on dangers, harms and efforts at work, and special attention is given in the chapter that emphasizes the obligation of the employer to conduct education on safety at work. Safety when using personal protective equipment and protective clothing is also shown. In addition to conducting the training itself, it is necessary to encourage workers' awareness of risks and the importance of responsible behavior in order to minimize these risks. The paper presents the implementation of occupational safety and fire protection in the factory, on a selected example of Nexe company.
