Introduction: reduction of possibility risk in hospitals is an important and vital issue for improving the quality of health care. This research was conducted with the aim of identifying, analyzing and prioritizing risks using the failure mode and effects analysis (FMEA) method, providing solutions for reducing or controlling identified risks and examining the effective basics of risk management. Methods: Hospital risk management team consists of 10 experts, during the one-year time period, the risks in different parts of the hospital's health care through inspection, observation and review of processes, non-conformities and documentation, as well as participation of experienced treatment staff These risks were identified in different classes and finally, the risk priority number (RPN) was calculated using the Excel software and the corresponding formula. Results: Errors in nursing care were identified as the most important nursing work processes in the hospital. Of the number of identified risks, 22 were assigned RPNs above 150 that were in corrective proceedings priority. The highest RPN has been belonged to a failure to implement the blood injection guidelines (448) and then to medicate - missed dose process (336).   Conclusion: Major corrective proceedings include the formulation of educational programs, the adoption of policies and procedures, and the establishment of monitoring and evaluating programs to streamline risk management as well as reduction and control the risks in the hospital is considered as main part of the human resource management (HRM).   Keywords: Risk Management, Human Error, Hospital, FMEA, Human Resource
