IS Questionnaire helps to identify the severity of pain that a worker suffer while conducting their tasks. This questionnaire is used for defining the harmful factors of Work-related Musculoskeletal Disorders. Lack of established analytic systems and experts in Ergonomics makes the investigation of the harmful factors of Work-related Musculoskeletal Disorders which burdens employers. Cumbersome and costly as a result, KOSHA Guide H-9-2012 is mandating to conduct the investigation within 1 year since foundation for start-ups and once in every 3 year is barely complied by employers resulting in poor implementation of investigations. While conducting the investigation on harmful factors of Work-related Musculoskeletal Disorders,we are able to learn the severity of pain that a worker suffers while conducting their tasks by having them to fill out Individual Symptom Questionnaires. This study is designed to develop simplified anticipation table that facilitates the labor/management cooperation and shorten investigation lead-time in selecting the burdensome tasks that could cause Musculoskeletal Disorders. This simplified anticipation table is based on the analysis of ISQ to identify the harmful factor of Work-related Musculoskeletal Disorders. The simplified anticipation table was made based on the result of the ISQs by employees of General hospitals, nursing houses, wholesale warehouses and College janitors. The difficulty of task reflected on the questionnaire was compared with task analysis of employees with the help of the metrics in ergonomics such as RURA, REBA, OWAS. By pinpointing the ailing body parts by each industry and task using the result of questionnaire, we developed the customized simplified anticipation table which reduces time and cost consumed in defining harmful factors of Work-related Musculoskeletal Disorders. Simplified anticipation table compared with the result of ergonomics analysis of an employee who is conducting burdensome tasks that could induce Work-related Musculoskeletal Disorders which IS table reveals that 11 burdensome tasks notified by the Ministry of Employment and Labor existed in common at the studied workplaces. The result of our analysis found that ISQ in certain industry doesn’t serve well in selecting burdensome tasks. Therefore, there is an urgent need to develop customized simplified anticipation table with imposing weights into intensity and frequency of tasks and manual to avoid risk of Work-related Musculoskeletal Disorders.
