Dysergonomic Risks and Musculoskeletal Disorders in Mining Sector Workers
Keywords:
ergonomics, musculoskeletal disorders, mining, occupational health, manual handling, Nordic Questionnaire.Abstract
The objective was to analyze dysergonomic risks and musculoskeletal disorders among operational workers at Minervilla S.A. A quantitative, descriptive, non-experimental study was conducted. The population comprised 116 workers and the sample consisted of 89 participants, compatible with a finite-population calculation using a 95% confidence level, 5% margin of error, and maximum variability. ISO/TR 12295:2014 and the Standardized Nordic Musculoskeletal Questionnaire were used. Manual load lifting (95.5%) and forced postures and movements (88.8%) were the predominant hazards. Low-back symptoms were the most frequent (59/89; 66.30%), followed by neck (31.46%), shoulders (25.84%), upper back (22.5%), and wrists (20.2%). Among workers with low-back symptoms, 69.49% reported symptoms in the previous seven days and 55.93% reported activity limitation. Fisher's exact test yielded p = 1.00 in the documented comparison, which does not support a statistically significant association. The findings therefore document a high descriptive burden of dysergonomic exposure and musculoskeletal symptoms and support preventive ergonomic measures.
