ارزیابی ایمنی واحد تولید گلوکز به روش ردیابی انرژی و آنالیز حفاظ ها در یک شرکت گلوکزسازی

  Background and aims   Each year many people die from accidents at work. Enormous costs of these accidents have forced specialists looking for ways to prevention of accidents. This study focuses on evaluation the safety of glucose production unit by energy trace and barrier analysis (ETBA) and present approaches to prevention of accidents.   Methods   Steps to perform ETBAmethod was completed in the field study. Data was collected by interview with workers and supervisors, document surveys and direct observations. 41 ETBA worksheets were completed for seven fold parts of production unit. Most unacceptable risks were   found in starch site.   Results   Findings showed that unwanted flow of potential energies create the most unacceptable risks in production unit. We concluded that the human factors would play main roll  in reduction of risks and control hazards. Also, administrative controls are suggested, especially  establishment of repairing and preventive maintenance system, organizing team for investigation  and record keeping of accidents, reporting and scientific analyzing of accidents and incidents  would reduce the total risk of industry.   Conclusion It will be useful to use the techniques that research human role in accidents associated with ETBA method.
