Sažetak

This study conducted ergonomic risk factors assessment of maintenance job in a gas generating power station with a capacity of 8.4 MW (1.4 MW x 6 units) and 12 maintenance staff. The ergonomic risk factors present in the maintenance job were identified as task, personal and environmental. The potential severity of all the recognized risk factors and probability of occurrence were assessed on a scale of 1 to 5. The risk index was determined as the product of probability of occurrence and potential severity of all the risk parameters. The relative weights of the parameters of the risk factors were determined by dividing each cumulative risk index by the total cumulative risk index. The relative weights of the ergonomic risk factors were determined by dividing the cumulative risk index for each factor by the total of the cumulative risk indexes. The total risk index for each factor was calculated by summing up the product of the relative weights and the risk indexes of the parameters that make up the factor. The Work Severity Index (WSI) was determined by summing up the product of the relative weights and the risk indexes of the ergonomic risk factors. The risk values were categorized into three classes of low, medium and high risk. Using the personal and environmental factors, the average risk values were 3.03 ± 0.42 and 3.00 ± 0.00 respectively signifying that the job was a low risk one. The value of the average Work Severity Index was 5.03 ± 1. 62 which showed that the maintenance job as it was practised in the power station under study was of low risk.
