Background and aims
Risk perception is a key parameter influencing the behavior of the
workers 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.
Methods
Five 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 workers
was estimated pro and post application of Job Safety Analysis. The questionnaire included
different groups of questions for clarifying the risk perception of workers from different point of
views. Same workers were asked to answer these questions before and after applying the job
safety analyses. The results were evaluated to identify whether the job safety analyses does
influence the risk perception of workers or not.
Results
The analyses of 50 jobs active in production line and technically supporting sections
showed that welding, cutting, scaffolding, insulating and piping have the highest risks
respectively. 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 personal
protective equipments. This effect was different among different categories of jobs, aging,
working experience and literacy rate.
Conclusion
The application of the JSA may modify the risk perception while identifying the risks.
