Risk evaluation of belt conveyor accidents using failure modes and effects analysis and event tree analysis

Abstract

Belt conveyor haulage is an often-preferred haulage method in raw material transport of industrial facilities. Main components of the system often subject to breakdowns are belt, drums, roller systems and belt tension drum systems. Among these components, belt breakdowns are belt ruptures due to corrosion, inability of rotation due to corrosion and dust in cylinders and mechanical failures in drum systems and components. In this study, risk evaluation was carried out on probable risks due to breakdowns and faults in a bad conveyor facility. Realised accidents in industry are considered to specify risks. In the first step of the study, Failure modes and effects analysis was employed. Upon results of FMEA, event tree analysis was carried out for each risk in order to display and decrease severity degrees of risks.
