Human Hazard and Operability Stady in a Oxygen Supply System in Qazvin Bu Ali Hospital in 2022
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 have disastrous results. The purpose of this research is to analyze the risk of the oxygen supply system of one of Qazvin hospitals using the method of studying risk and human performance.
In this research first, 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; then 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. Then, the types of errors and causes were identified and proposed controls were presented to reduce unacceptable risks.
According to the 75 scenarios obtained from the method used, the results indicate that failure to perform job duties with 32.42% as the most important parameter, with the most important 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.
This method can be used to reduce the risk of fire, explosion and reduce the 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
