Background: This study aimed to evaluate ergonomic behaviors and to determine the importance of each ergonomic behavior in an Iranian petrochemical company. This study was conducted in Khuzestan petrochemical company, which is located in the south of Iran, in 2010. Methods: The methodology was based on the Ergonomic Behavior Sampling (EBS), and by entropy. After specifying the non-ergonomic behaviors and with reference to the results of a pilot study, a sample of 1755 was determined, with a sampling accuracy of 5% and confidence level of 95%, however, in order to have more confidence, 2631 observations were done. Results: The results indicated that 43.6% of workers' behaviors were unsafe. The most frequent non- ergonomic behaviors were using of legs for load lifting (83%). The highest and lowest weights, which are obtained by entropy, belong to load carrying with correct weight behavior and neck posture behavior with weight of 0.370 and 0.0052, respectively. Conclusion: Taking into account catastrophic consequences of accidents in petrochemical industry, the results show the importance of paying attention to safety principles and to develop a positive attitude among employees toward safety
