Abstract
Introduction: In many workplaces today, the incidence of human error can lead to catastrophic accidents in which human error is the main cause of accidents. Due to the vital role of the control room in guiding and controlling various sites of the pipe industry, especially the outer coating sector, the incidence of any error can lead to human accidents, damage to machinery, and interruption in production. This study aimed to identify and evaluate human error by Human Error Calculator (HEC) method in the epoxy control room of a pipe mill company.
Materials and Methods: In the present descriptive cross-sectional study, the HEC method was used to identify and evaluate human errors. The HEC technique is provided by Risk Map Company, in which the probability of human error is based on five factors affecting the occurrence of human error, including a degree of urgency, complexity, importance, degree of individual skill, and task repetition, using a disk-shaped tool called Risk Disk is determined through direct observation, available instructions and interview with the head of the mentioned unit.
Results: According to the results of this study, out of 11 identified tasks, five job tasks with a risk number of 70% have a high probability of human error, four job tasks with a risk number of 50%, and one job task with a number There is a 40% risk of moderate human error, And a job task with a 20% risk number has an increased chance of human error.
Conclusion: The results of the present study showed that the HEC method is easy to use and is a simple and useful tool for professionals to calculate the probability of human error. In addition, HEC is a practical, effective and beneficial method for managers to reduce human error.

Abstract
Introduction: Work-related musculoskeletal disorders are the most common and costly preventable occupational problem that office workers suffer from the discomfort associated with these disorders. The aims of this study were to a) investigate the prevalence of low back pain (LBP) and b) continuously assess the trunk postures of office workers
.Materials and Methods: Thirty-six office workers of a medical university participated in this cross-sectional study. Thirty-six office workers of a medical university participated in this cross-sectional study. The prevalence of LBP was determined using the Nordic Musculoskeletal Questionnaire. Work trunk postures were measured using an inclinometer.
Results: More than half of the subjects reported LBP. There was a significant relationship between LBP with age, work experience, working hours, and gender (p <0.05). The mean maximum trunk flexion angle was 35.41±13.72, and the mean maximum angle of lateral bend in the frontal plane was 9.86±3.2. The mean trunk angles for all percentiles and plates studied were significantly different between men and women; It was more in women than men (p <0.05).
Conclusion: The results of this study showed that there are awkward and static postures lumbar among office workers that can be considered risk factors for developing LBP. The findings can help to establish guidelines regarding prioritizing ergonomic interventions to reduce the prevalence of LBP among office workers.
