Introduction: To reduce occupational accidents and work-related diseases as well as improving satisfaction of working conditions, Assessment to identify risks and control measures are necessary. The aim of this study, applying ergonomic assessment indices to assessed the job groups and ability of textile workers.

Materials and methods: This study was conducted on 194 men employed in the QaemBaft textile company. Relative Stress Index (RSI) was used to assess the textile job groups. Also; Work Ability Index (WAI) was used to assess the personnel’s ability.

Results: Results of RSI for 15 job groups showed that all jobs were in the Safe zone. Also results of WAI showed that only “Open “job was to have good level of ability and other job groups were to have intermediate level of ability.

Conclusion: According to the results, Relative Stress Index (RSI) is a tool for macro-ergonomics assessment of job risks. Also, in six categories of tasks of RSI, levels of fitness is determined. But WAI, Ability to work is determined that is a wider earning than the fitness.

Keywords: Relative Stress Index (RSI), Work Ability Index (WAI), macro-ergonomy, risk assessment
