In this paper, the author will point out the determinants of safety and security at work in the context of the requirements of the HSEQ (Health, Safety, Environment and Quality) standard with practical application on the construction site in the context of maintenance of technical systems. The key determinant in the occupational safety approach in the context of general safety and maintenance of technical systems is prevention. Prevention implies planned and undertaken safety measures in every work procedure at the employer, with the aim of preventing or reducing risks at work. When basic organizational safety measures, i.e. basic rules and equipment for work protection, cannot eliminate or sufficiently limit the risks to the safety and health of workers, the employer is obliged as part of specific security to provide additional appropriate protective equipment and additional work protection measures, and ensure the training of workers in order to use it in a prescribed and correct manner. In this paper, the author will give numerous examples of the practical application of specific safety in specific working conditions. In this paper, the author will give examples of the application of prevention and general work safety with risk assessment on the construction site in the specific case of a renowned company with extensive international experience.

In the present paper is proposed a classification of the problems and the mathematical models for choosing optimal structural variant while designing a technical system. Algorithms and software models were developed based on known methods for determining the priority of criteria functions. The algorithms and models are implemented in a dialog system for structural optimization. Results are shown from using the software for solving a particular problem.
