  Background and aims

 Today in many jobs like nuclear, military and chemical industries, human errors may result in a disaster. Accident in different places of the world emphasizes this subject and we indicate for example, Chernobyl disaster in (1986), tree Mile accident in (1974) and Flixborough explosion in (1974).So human errors identification especially in important and intricate systems is necessary and unavoidable for predicting control methods.

  Methods

 Recent research is a case study and performed in Zagross Methanol Company in Asalouye (South pars).

  Walking –Talking through method with process expert and control room operators, inspecting technical documents are used for collecting required information and completing Systematic Human Error Reductive and Predictive Approach (SHERPA) worksheets.

  Results

 analyzing SHERPA worksheet indicated that, were accepting capable invertebrate errors % 71.25, % 26.75 undesirable errors, % 2 accepting capable(with change) errors, % 0 accepting capable errors, and after correction action forecast Level risk to this arrangement, accepting capable invertebrate errors % 0, % 4.35 undesirable errors , % 58.55 accepting capable(with change) errors, % 37.1 accepting capable errors .

  Conclusion

Finally this result is comprehension that this method in different industries especially in chemical industries is enforceable and useful for human errors identification that may lead to accident and adventures.
