Abstract 
Introduction: In the modern industrial world, the health of the employees in different Occupations can be influenced by the interaction of various risk factors. So, the purpose of present study was to assess and analyze the relationship between the factors including shift work, job stress, job satisfaction and health in a petrochemical industry.
Materials & Methods: The present study was conducted using analytical and cross-sectional method. The statistical population was all employees of a petrochemical company (4000 people). Using the Cochran formula, a sample of 360 individuals were selected using simple random sampling method. Data was collected using a high reliability integrated questionnaire (Cronbach’s alpha = 0.83). Data was analyzed using SPSS22.0.
Results: The analytical results of relationship between shift work, occupational stress, occupational satisfaction and health showed that all hypotheses in the conceptual model were approved and there was a significant relationship between these factors (P<0.001). Also, the results showed that, in addition to the direct effect of shift work on health, due to the effect on occupational stress and occupational satisfaction, it was indirectly related to health (P <0.001).
Conclusion: The findings indicated that shift work as a direct factor and as a mediator and indirect factor through impact on factors such as occupational satisfaction and stress can affect the health of employees. Therefore, considering this organizational phenomenon and its redesign or its change can play an important role in increasing the level of occupational health and motivation as well as organizational productivity.

Abstract
Background and Aim: Petrochemical industry is one of the most accident-prone industries, and most accidents in this industry are related to human factors. The principles of Lean production are one of the approaches used to improve the production situation. Various studies have shown that implementing Lean production improves the safety and ergonomics. In this study, the principles of Lean production were used to reduce human error and improve response in emergencies.
Methods:  The basic CREAM method was used to evaluate human errors. In order to select Lean production tools appropriate to the emergency response tasks, the opinions of the 20-member panel of specialists and experts, including industry managers, HSE officials, and university professors, were used. For examining the impact of Lean production principles on reducing human error in emergencies, 6 months after the implementation of Lean production interventions, human error was re-examined. Evaluation of human errors after Lean production interventions was also performed by basic CREAM method.
Results: The results of the evaluation of human errors before and after the implementation of Lean production interventions showed that the level of control mode of the three sub-tasks improved from the tactical control mode to the strategic control mode. The most probable human error was in evacuate sub-task.
Conclusion: The results of this study showed that the implementation of those interventions that in addition to improving the level of safety, can improve organizational productivity, is more accepted by industry management.
