بررسی تأثیر آموزش بر کد ارزیابی ریسک به روش تجزیه و تحلیل ایمنی شغلی کمی شده در یکی از واحدهای شرکت تولید سیمان

Introduction: Technology updates and the arrival of new machines have caused occurrence of many injuries and job deaths in industries. In any job, technical controlling practices accompanied by trainings and executive instructions can be implemented after doing job safety analysis. The aim of this study is the investigating the effect of training on risk assessment code in a load house of cement production plant with a technique of quantified job safety analysis. Methods: The study was a before and after study with an interference by safety training program that has performed on ten jobs in a load house of the cement production plant. In this investigation, after determining jobs and grouping hazards in job safety analysis (JSA) table, rate and probability of risk are extracted from particular tables that are translation of standard MIL-STD-882E tables (5th edition) and the initial risk assessment code (RAC1) was calculated. According to JSA tables, training requirement of jobs was done and training program was determined and it was presented despite of safety job instruction for job owners, and then secondary risk assessment code (RAC2) was determined. Results: Totally, 119 risks were detected in ten investigated jobs. From these, %53.33 in the acceptable risk range, %22.5 in the lowest acceptable risk limit range and %24.17 in unacceptable range were laid. The risk rate (%) was changed to %69 in acceptable risk range and %31 in the lowest acceptable risk limit range after doing interfering. Conclusions: This study showed that decreasing rate of incidents and hazard controlling in workplaces can be achieved by perform training courses and relearning programs.
