Introduction: Numerous studies have shown that human error is the main factor in the occurrence of occupational accidents. Diversity of a job’s different aspects, nature of the job and its complexity, can negatively affect a worker’s performance and behavior, thus leading to unsafe acts in a working environment. This also causes workers to intentionally or unintentionally make errors, which itself can be a reason of occupational accidents. Methods: This study is an analytical- descriptive research, where Barrier Analysis (BA) technique has been applied to identify and analyze the nurses’ human errors in the CCU ward of NIOC Tehran hospital. Results: The results of the BA checklists presented 57 barriers classified in 8 groups: administrative barriers (14%), procedural actions (18%), human actins (10%), supervisory and co-working barriers (20%), training (10%), natural barriers (0%), physical barriers (10%) and environmental design (18%). Also, 38 barrier breakers and 32 corrective actions were identified. Conclusion: It can be concluded that BA technique is an appropriate technique to be used in the healthcare and therapy industry as it is helpful in the identification of human error protection layers.
