The paper presents the analysis of the application of FMEA method of storage system in the area of a metallurgical enterprise performing gray iron castings according to the PN-EN 1561: 2000 and PN-92 / H-83101 standards as well as alloy cast iron. Casting is a technology for making objects by filling molds with liquid metal. Castings are made of cast steel, cast iron, aluminium, magnesium and copper alloys. The casting technology could be used to form objects of very complex shapes with very high accuracy, eg pistons, motors, casings, tools. The aim of the publication is to realize the FMEA method of the warehouse system so as to find the causes of defects, to remove errors and to commit repair tasks, so that the whole planning and storage process takes place in an effective manner, while reducing the criticality priority of defects in all cases. After performing the FMEA analysis all the defects, causes and effects occurring in the process were determined from demand for goods planning up to delivery and quantitative and qualitative control. Ishikawa's cause-effect diagrams were used to detect the exact causes of the most important defects in the process and then corrective actions were recommended. Among the six included actions of the process the two most difficult actions were identified which should be addressed first. An effective solution for these two process activities is the systematic update of the list of preferred suppliers and the employment of an auxiliary employee supervising and approving the procurement plan.Keywords: metal foundry, grey and alloy cast iron, Mode and Effects Analysis, warehouse system, importance of defects, failure
