Methodology of identification of revisions and inspections of technical equipment for a manufacturing company based on the requirements of ISO 45001
Valenta, Jakub ; Jandová, Kristýna (referee) ; Bača, Petr (advisor)
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. In the introduction, these fields of work safety and fire protection are described, which will be used in later parts of the work. Subsequently, the term „technical equipment“ and subcategories of this issue are defined, with each of the subcategories being specifically approached. As a result, the thesis describes why it is necessary to regularly inspect the technical equipment, while the individual types of inspections are subsequently defined. 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. This model and review of inspections are then considered the output of this bachelor’s thesis.
