Abstract: Technological and scientific advances have imposed more serious risks on human force, machineries and assets. On the other hand, it is essential to prevent accidents and preserve human and financial capital. Risk assessment is an organized and systematic method to detect and estimate risks. Based on the results, risk assessment can rank the decisions and reduce the risks to an acceptable level. The present study has aimed at detecting, assessing and controlling the risks in a wheat winnowing workshop affiliated to Kermanshah Province floor factories (Iran). The study was carried out through a descriptive cross-sectional study in 2015. Energy trace and barrier analysis methodswere followed. An analytical method was used based on system safety which has been implemented to detect and define the risks that may cause damage and loss to the system. To collect the data, ETBA worksheets were filled through walking-talking method and technical/operational document reviews. Based on the results, modifications of the systems and standards were recommended to minimize the risks. The results revealed 8 energies and 28 risks, out of which six risks were unacceptable, twenty risks were non-preferred and two risks were acceptable, after revision. None of the risks were at acceptable levels without revision. After implementation of adjustments there were zero unacceptable risk three non-preferred risks and six acceptable risks after revision and 19 acceptable risks, without revisions. Taking into account that most of the risks were at high levels, controlling the measures based on experts’ prescriptions in safety areas, pertinent to equipment, training operators and monitoring the measures were recommended.
