Resumen
FLORES GUILLEN, Raúl Danny y PALOMINO BALDEON, Juan Carlos. Changing the level of ergonomic risk in forced postures and repetitive movement by redesigning the blowing machine for plastic bottles. Rev Asoc Esp Espec Med Trab [online]. 2023, vol.32, n.4, pp.330-344. Epub 15-Ene-2024. ISSN 3020-1160.
Objective:
To compare the change in the level of ergonomic risk in forced postures and repetitive movement due to the redesign of the job of a plastic bottle blowing machine in a factory in the city of Lima.
Material and Methods:
The methodologies used for work postures and repetitive movement were the ISO 11226:2000 and OCRA Checklist standards, respectively.
Results:
The risk levels of the workers in the first evaluation of OCRA Checklist for repetitive movements gave levels of “medium risk” and “high risk” and for forced postures evaluated by ISO 11226:2000 it was at the “not recommended” level. After the ergonomic redesign, the “acceptable risk” level was obtained.
Conclusion:
In the bottle supply process for blow molding machines, initially they did not present acceptable ergonomic criteria for the dangers of repetitive movement and work postures. However, when carrying out the redesign of the workplace, “acceptable” risk levels were obtained.
