Occupational Health and Safety in Workplaces

This study was conducted with 90 poultry slaughterhouse workers, which perform the function of removing chicken parts from the conveyor belt, and sample was composed of 66 women (33.5 ± 6.5 years) and 24 men (35.7 ± 7.2 years), aiming to analyze the influence of anthropometry in the shoulder joint of these workers. Body discomfort was evaluated by a human body diagram, being applied at the end of the work shift. The anthropometric measurement of shoulder was performed by measuring the height of the acromion process, being compared with the height of the conveyor belt. Analysis of the results was performed by descriptive statistics, mean, standard deviation, percentage and percentiles 5%, 50% and 95%. It was found that the height of the conveyor belt was 1.74 meters, while the average shoulder height of workers was 1.38 meters for percentile 5%, 1.41 meters for percentile 50% and 1.65 meters for percentile 95%. The discomfort regions were shoulder 45%, neck 29%, column 26%, arms 23%, and wrists and hand 20%. The upper limb assessment was performed with percentile 5% through the Rapid Upper Limb Assessment method, resulting in a final score > 7, indicating the need for adjustments of the work organization. It was concluded that the workplace does not meet the workers' anthropometric characteristics, mainly affecting the shoulder joint, and correction ergonomics becomes necessary so that the workers involved in this study can perform their functions with health, comfort and safety.
