Abstract:

Introduction: The use of risk significance analysis for ergonomic job design is an alternative that can help reduce harmful effects on the health of workers and pay fines from employers. Objectives: A workstation was ergonomically designed with exposure to uncomfortable postures for the cashier in supermarkets belonging to the La Favorita company located in Ambato (Mall de los Andes), for which the critical variables to be controlled with the Rapid Upper Limb Assessment (RULA) method were established and then designed the position anthropometrically to improve posture. Methodology: The design results determine the following angles: arms 20-45; forearm: 60-100; pronation wrist; neck: 0-20 and legs with support. The final risk level of RULA on both sides of the body was lowered by 66.6% by changing the reception table 90 from the front and the dispatch table on the right side. As conclusions of the study, we can say that the level of risk due to forced postures decreases 4 points from the final RULA result, considering the workstation design proposal, the wrist must exercise pronation, and the worker must stand with the weight of the body distributed in both legs, and on the work, surface must be rotated 90 and the desk for dispatch on the right side. Conclusion: The ergonomic redesign of the supermarket cashier's workplace decreased the RULA risk level of the upper extremities by 66.66%. Spanish abstract: Introducción.
