description Background and Objective: Central oxygen is one of the vital parts of hospitals responsible for supplying oxygen. Therefore, any defect in this system can result in human and financial losses. Therefore, effective risk analysis is of utmost importance in the prevention and mitigation of such potential accidents. In the light of aforementioned issues, the current study aimed to analyze the scenarios of accidents in the oxygen central unit of the hospital using Fault Tree Analysis (FTA) and Layer Of Protection Analysis (LOPA) methods. Materials and Methods: In the first step, probable errors in oxygen leakage were identified and then FTA was plotted. Dangerous scenarios in central oxygen were identified and the risks were analyzed using the semi-quantitative LOPA method. Finally, control measures were proposed to reduce oxygen leakage.     and semi-quantitative LOPA method was used for risk analysis. Finally, control measures to reduce oxygen leakage were predicted Results: As evidenced by the obtained results, the most important accident scenarios include oxygen release, explosion, and fire. Independent protection layers are suitable for oxygen storage and production tanks, and the use of Independent Protection Layers (IPL) can significantly reduce the risk. The most important cause of leakage in the patient's room was due to the mask being removed from the respiratory area or the lack of fit with the patient's face. Conclusion: The results of this study showed that the independent protective layers in central oxygen are sufficient to prevent oxygen leakage. It is also necessary to use a sensor to determine the concentration of oxygen in the patient's room and a special alarm to increase the concentration of oxygen in order to reduce the risk of oxygen leakage in the environment. Furthermore, periodic training to all employees and maneuvers should be implemented in the crisis management measures in hospitals.
