The state of the technical infrastructure determines the degree to which the quality requirements of products are
met and has a significant impact on occupational safety. The purpose of this study is to build a universal model
for supporting quality management, which allows the effective implementation of a wide-ranging research path
supporting the evaluation of the relationship between the degree of modernity of product processing technology and the quality of the final product and the level of occupational safety. The developed model is verified
by its implementation in one of the turning stations. A practical test of the quality management support model
confirms that the practice of conducting analyzes of the level of modernity of infrastructure with its application
contributed to identifying critical machine components, examining factors affecting the quality of technological operations, reducing uncertainty and the risk of risky events, and conducting activities in line with the
concept of continuous improvement. The course of action detailed in the model makes it possible to determine
the relationships that exist between key categories of factors and critical product defects, and accidents and
near-misses. This allows for the proposal of adequate improvement measures. Further studies concern the implementation of the model at other workstations in the foundry company
