The aim of this study was to evaluate the risks in relation to repetitive movements of the upper limbs in a poultry slaughterhouse, as well as analyze the effects of a reduced work pace on the risk levels. The study was conducted in a slaughterhouse with 1,500 workers, who were divided into two shifts, where 150,000 chickens were slaughtered daily. The OCRA checklist was implemented to assess 10% of the total workforce. The Student t-test was applied to examine the difference between the risks of both sides of the body (p ≤ 0.05). The 14 analyzed work tasks were from the sectors: cutting (8), packing (5) and reception (1). The workers performed 72.8 ± 15.3 actions per minute (10/10 points on the OCRA scale). The average score of the OCRA checklist was 23.4 ± 4.4 (high risk). The scores for the right upper limb (23.1 ± 4.8 – high risk) were not significantly different (p = 0.175) than the left (21.8 ± 5.2 – moderate risk). Considering the five risk categories of the OCRA method, 10 tasks were deemed high risk (71%) and 4 presented moderate risk (29%). By conducting simulations, it was possible to reduce the risk to a very low level in 13 of the 14 tasks by only decreasing the work pace (−56.9 ± 10.4%). In this way, simulations of a reduced work pace showed the effectiveness of this organizational measure in lowering the risk of UL-WMSD.

Diogo Cunha dos Reis & Antônio Renato Pereira Moro
Federal University of Santa Catarina Florianópolis, SC, BrazilThe aim of this study was to evaluate the risks in relation to the workers’ repetitive upper–limb movements, as well as analyze the effects of a reduced work pace on the risk levels in a fish processing industry. The study was conducted in a Brazilian fish processing industry with 1,900 workers, who were divided into two work shifts. The OCRA checklist was used to assess 10% of the total workforce during work tasks. The 13 main work tasks (homogeneous groups) of the productive sector were analyzed. The occupational repetitive actions performed by workers were 81.5 ± 19.2 per minute, representing 10 points on the OCRA scale (0–to–10–point scale). The average OCRA checklist score was 18.4 ± 2.9 (moderate risk). The scores for the right upper limb (18.3 ± 2.8 – moderate risk) were significantly higher than the contralateral limb (16.0 ± 4.2 – moderate risk) (p = 0.014). Considering the five risk categories proposed by the OCRA method, 12 tasks were deemed moderate risk (92%) and 1 low risk level (8%). Due to the predominance of the highly repetitive upper–limb movements in fish processing work, and previous studies suggesting a reduced work pace to prevent UL–WMSDs, simulations of a pace with very low risk levels were carried out utilizing the OCRA checklist. By conducting these simulated interventions, it was possible to reduce the UL–WMSD risk to very low levels in all tasks by only decreasing the work pace (–42.8 ± 17.7%). These results suggest that most of the tasks that workers performed were classified as moderate risk, predisposing workers to a greater probability of developing UL–WMSDs (10.8 to 21.5%) than the population that was not exposed. Simulations of a reduced work pace showed the effectiveness of this organizational measure in lowering the risk of UL–WMSDs.

SISTEMA INTEGRADO DE GESTÃO ERGONÔMICA E VIGILÂNCIA EM SAÚDE EM EMPRESAS DE ABATE E PROCESSAMENTO DE CARNES
Publicado em 16/03/2022 às 18:46Este projeto integra uma iniciativa de estudo em segurança e saúde em empresas de abate e processamento de carnes com o objetivo de proporcionar elementos para a adequação das condições de trabalho atendendo a necessidades tanto do ponto de vista estratégico quanto legal. Estratégico, pois trata da certificação corporativa em segurança e saúde conforme normas ISO e OSHA; legal, pois busca o atendimento das Normas Regulamentadoras, dentre as quais a NR-36, NR-17, NR 04, NR 07 e NR 15. Nesse contexto, pretende-se estabelecer um novo olhar para as questões que circunscrevem o trabalho no setor de frigoríficos no Brasil. Dentre outros fatores, a ideia principal é estruturar um banco de dados, informações e publicações científicas, que permitam a devida avaliação e adequação das condições de trabalho nas empresas de abate e processamento de carnes.
