This ergonomic study has focused on the production line workers in food industry because of the presence of repetitive tasks. This study’s objective is to understand the working methods and the workers’ organization, analyzing repetitive movements of upper limbs, in order to suggest a better distribution of the workload, and reduce the risk of musculoskeletal injury. In total, there are 6 female workers who are exposed to repetitive motions. A time and motion study was carried out, as well as the OCRA (Occupational Repetitive Actions). In conclusion, all repetitive tasks are at Risk (OCRA index> 3.5) according to OCRA index. The main causes include: the worker’s position on the line, the frequency of actions per minute, the duration of exposure, the lack of recovery time, among others.

Palabras clave : repetitive motions; upper limbs; job rotation.
