The paper describes the organization of the implementation of protection at work in the Zagrebparking branch. I have been working in the branch as a protection expert since 2007, where I started from the very beginning, from the organization of documents to the implementation of safety and protection of the health of workers at work. In this paper, I focused on the safety and health of workers at work, i.e. the responsibility and obligations of the employer through the employer's authorized representatives for protection at work and the commissioner of workers for protection at work. In occupational safety, it is important to prescribe every work procedure, taking into account the opinion of the workers' representative or the worker's commissioner for safety at work. The most important document in occupational safety is the risk assessment, which is also prepared by the commissioners of occupational safety and occupational medicine specialists and other interested participants in occupational safety. The risk assessment defines and describes the work performed by the employer and special attention should be paid to work with special working conditions. Based on the prepared risk assessment, accompanying acts are also prepared, which regulate in more detail safety at work and the work of workers at individual workplaces or workplaces.
