This work deals with the issue of inspections and revisions of technical equipment according to safe operation standards on the basis of OSH and FP requirements.

This is accompanied by the distribution of the person’s rights to carry out individual inspections and the distribution of responsibility for the inspections carried out. The acquired knowledge is then used to create a model of the process of regulation of inspections and revisions and to create an overview of periodic inspections and revisions of technical equipment for a manufacturing company.
