Ergonomic assessment of the activities developed by the canteen professionals of a Portuguese university: study of the main WMSD risk factors
| Resumo: | Work-related musculoskeletal disorders (WMSD) are currently one of the main causes of absenteeism related to health problems. Taking into account that he work was carried out in an industrial kitchen, where different types of activities are performed, this study aims to identify and characterize the activities to evaluate the ergonomic risks to which the employees are exposed. Those risks are associated to postures, repetitive movements, manual handling of loads, among others. The analysis allows giving recommendations to reduce the risk of musculoskeletal disorders. The main methodologies used were a questionnaire based on the Nordic questionnaire, videos, direct interviews with the employees, which allowed to choose the main activities in which there were flaws in the ergonomic factors. The Rapid Entire method Body Assessment (REBA) was used for the evaluation for those activities in which there were repetitive movements, incorrect postures, whereas the Key Indicator Method (KIM) was used for the activities involving manual handling of loads. Twenty-three workers were evaluated obtaining the body regions with the highest percentage of musculoskeletal complaints in the last 12 months: the lumbar area with 83%, 74% feet, and 74% neck; these body areas coinciding with absenteeism in the last 12 months with 57% lumbar, 48% feet and 43% neck. An average was obtained for the pain scale, ranging from 0 (without pain) to 10 points (maximum pain), giving 7 points for the lower back and 6 points for both the feet and neck. Six activities were evaluated with the KIM method and the results show that five activities obtained a medium-risk level and the sixth activity a high-risk level in terms of classification It was concluded that the typical activities of the canteen can generate musculoskeletal disorders in workers, for which a series of recommendations are given. |
