Biomechanical hazard in manual handling of cargo in workers of a sugar mill

Abstract

Introduction: During the activity of manual handling and transport of loads, forced postures are adopted for a long time that mainly affects the spine and upper limbs, generating symptoms that include pain, stiffness, limitation in movement, joint inflammation, numbness, among others. increasing the rates of absenteeism and morbidity of musculoskeletal origin. This research aimed to identify the biomechanical hazard associated with the appearance of musculoskeletal disorders in dispatch workers in a sugar mill during the year 2019-2020.

Methods: 14 male employees were evaluated, with an age range between 35 and 48 years, to whom the INSHT load lifting guide method was applied to determine the level of biomechanical risk and the perception of symptoms was evaluated. through the Nordic Questionnaire.

Results: It was evidenced, a non-tolerable risk level since the workers handle loads that excessively exceed the acceptable weight suggested for this work, and the presence of musculoskeletal symptoms in the cervical, lumbar, shoulders and wrists.

Conclusions: The workers presented a high level of biomechanical danger, which can cause occupational diseases and consequently, functional limitation or physical disability, if corrective measures are not taken in time, both in the weight of the load and in the very development of work activity.
