Introduction: This study presents an epidemiological analysis of musculoskeletal diseases affecting the upper limbs of plumbers at the Bogotá Water and Sewerage Company. Ergonomic risk factors and working conditions that have contributed to the high prevalence of these pathologies were identified. A sample of 20 workers from Zone 3 was selected to apply the OCRA method, interviews, and anamnestic questionnaires. The results demonstrate the need for ergonomic interventions to mitigate physical strain and improve working conditions. An action plan based on tool redesign, active breaks, and ergonomic training is proposed. The findings seek to contribute to reducing the incidence and prevalence of occupational diseases, thus improving worker well-being and productivity.

Objectives:

• To determine the incidence and prevalence of musculoskeletal diseases in the upper limbs of plumbers in Zone 3.
• To identify the main ergonomic risk factors associated with these pathologies.
• Design an intervention proposal that contributes to mitigating these risks.

Materials and Methods: The study involved a sample of 20 plumbers from Zone 3. Instruments such as the OCRA method, anamnestic questionnaires, and structured interviews were applied. Occupational history data from the previous five years were analyzed, and ergonomic conditions were assessed in the field.

Results and Discussion: The analysis revealed a high prevalence of musculoskeletal disorders, primarily in the shoulders and wrists. The OCRA method identified tasks with a high ergonomic load. The interviews revealed a perception of work overload. It is proposed to redesign tools, implement breaks, and reinforce training.

Conclusions: Musculoskeletal diseases in plumbers are closely related to poor ergonomic conditions. The application of the OCRA method and surveys allowed for risk characterization. The proposed measures are feasible and have the potential to significantly reduce musculoskeletal morbidity.
