بررسی تأثیر آنالیز ایمنی شغلی بر درک کارگران از ریسکهای شغلی در مشاغل پرمخاطره یک پالایشگاه

Background and aimsRisk perception is a key parameter influencing the behavior of theworkers at workplace. The present work contributes to study the effect of Job Safety Analysis(JSA) on risk perception of the high risk jobs in a refinery complex.MethodsFive high risk jobs were identified using "Drop off" method in a refinery complex.Risk perception was evaluated using a standard questionnaire. The risk perception of the workerswas estimated pro and post application of Job Safety Analysis. The questionnaire includeddifferent groups of questions for clarifying the risk perception of workers from different point ofviews. Same workers were asked to answer these questions before and after applying the jobsafety analyses. The results were evaluated to identify whether the job safety analyses doesinfluence the risk perception of workers or not.ResultsThe analyses of 50 jobs active in production line and technically supporting sectionsshowed that welding, cutting, scaffolding, insulating and piping have the highest risksrespectively. The results showed that, the application of the JSAwill significantly (PValue<0.01)increase the worker's risk perception of hazardous agents in the workplace, the utility accidents,human injuries, injuries at the workplace, production versus safety, accident reasons and personalprotective equipments. This effect was different among different categories of jobs, aging,working experience and literacy rate.ConclusionThe application of the JSA may modify the risk perception while identifying the  risks.
