Covid-19. The risk due to postural static load and the type of motorcycle in door-to-door food transport workers.

Abstract

Introduction. The pandemic has caused an unprecedented crisis. Everyone is struggling to respond to the health and economic crisis. New businesses and ventures have emerged, door-to-door food delivery has been an alternative. Objective. A study of postural static load was carried out with the Rapid Entire Body Assessment (REBA) method in the execution of tasks of motorized door-to-door food transport workers in conditions of biological risk generated by COVID-19 in Latacunga. Methodology. The study begins with a comparison of the level of ergonomic risk due to postural load with the application of the REBA method in three types of motorcycle chosen for their durability, performance, rack capacity, safety and cost. Then the variables that are part of the REBA method were analyzed considering the position of the: trunk, neck, legs, arm, forearm, wrist and their respective penalties for the execution of the activity, repetitiveness and postural changes due to the anthropometric location in the types of motorcycle studied. Results. The results determine that the position of the neck and trunk are the significant variables in the final result of the level of risk due to static postural load. Being the Dukare 125cc pasola type motorcycle that determines a 40% lower final score of the REBA method in relation to the 2 Yamaha and b 125 and 3 Suzuki Huracán 125 cc motorcycles due to low values ​​of the leg score by 50% for having instability and a better position of the trunk in the execution of the task by adopting an angle of 0 ° to 20 °. Conclusion. The best option to reduce the postural static load in door-to-door food transport is motorcycle 1 (type Pasola Dukare 125cc) for low values ​​of the leg score by 50% since motorcycles
