Assessment of Human Hazard and Performance in the Oxygen Supply System in Bu Ali Hospital in Qazvin in 2022

Background and Objective: Oxygen therapy is one of the integral parts of a hospital, which has been introduced as a therapeutic use of oxygen, and any human error in this field can cause disastrous consequences. The present study aimed to analyze the risk of the oxygen supply system of a hospital in Qazvin using the method of studying risk and human performance. Materials and Methods: In this research, firstly, study team members were selected according to the purpose of the study to benefit from their experiences in discovering the possible situations of human operation risks. According to the field visits, interviews, and existing documents, the duties of people related to the objective were analyzed by the Hierarchical Task Analysis technique. Following that, the types of errors and causes were identified, and proposed controls were presented to reduce unacceptable risks. Results: According to the 75 scenarios obtained from the used method, the results indicate that failure to perform job duties with 32.42% as the most important parameter, with the essential factors of human error, such as memory slip (38%) and heavy workload (31%), plays a role in the three categories of consequences of fire, explosion, and reduction of oxygen sent to the departments. Conclusion: This method can be used to reduce the risk of fire, explosion, and oxygen pressure sent to different units by using the techniques of improving working conditions, changing the way of training, equipping the oxygen concentration detection sensor, and using the liquid oxygen tank.
