Evaluación ergonómica y propuesta de rediseño de puesto de trabajo en el área administrativa de una empresa de servicios del sector de la construcción.

Abstract

Having a broad conceptual framework at both national and international levels, which associates musculoskeletal problems with the development of occupational diseases originating from poor posture and highlighting the issue of ergonomic risks faced by administrative staff due to the physical characteristics of their work positions, emphasized the necessity to control disergonomic factors in the administrative personnel of a construction services company. The control was executed through the redesign of workstations and the incorporation of various interactive elements aimed at minimizing the risk of postural deviations, associated with the potential development of musculoskeletal disorders. This initiative aims to enhance working conditions and foster the health and well-being of administrative personnel within the workplace environment. To attain this control, the following study stages were established: the ergonomic conditions of the job positions were identified through on-site observation, followed by the application of the Nordic checklist and questionnaire. The evaluation stage was carried out using the Rapid Office Strain Assessment (ROSA) method, which determined that both job positions were exposed to a high ergonomic risk. For the corrective measures stage, workspaces and their interacting elements were redesigned through the mplementation of ergonomic chairs, footrests, data display platforms, ergonomic mice, and desks. Both the footrest and the Postural Variation Device (PVD) platform were previously designed and manufactured. Subsequently, the implemented corrective measures were validated through a second application of the ROSA method, which allowed for a reduction in risk from high to low in both intervened positions. The implementation cost amounted to $1,060.
