Incidents are considered among the most important issues throughout of world, and in many industrialized countries, incident is the most important cause of death in people aged over 40 years. In this regard, one of the most important missions of professional health is reducing the work-related incidents and diseases. Accordingly, this research evaluates the effect of using warning signs on risk reduction using job safety assessment (JSA) method in one of the automobile cable manufacturing companies. This cross-sectional research was carried out on 9 jobs in one of the cable manufacturing factories. After identifying the considered jobs, the severity, probability and identification of risks of each of the jobs were extracted using the standard MIL-STD-E882 (fifth edition) tables and the assessed code of initial risk was calculated. The analysis was performed using the JSA method. After about one year, re-assessment was performed and the secondary assessment code was extracted and the results were analyzed using paired t-test statistical methods. In total, 9 jobs were selected. Based on the existing risks analysis, 73% of them were placed at the range of moderate risk, 16% of them were placed at the range of significant risk, and 11% of them were placed at the range of tolerable risk. The preparation, installation, and education of warning signs caused that 58% of the risks to be placed at the lower range. It should be noted that regularly holding of educational sessions for workers and supervisors during the year can contribute in stability of this result.
