Abstract
espanolIntroduccion: la industria manufacturera mexicana del ramo automotor emplea en promedio 8 millones 850 mil trabajadores al ano repartidos en los 32 estados, de los cuales Puebla contribuye con 465 106, desarrollando, en un alto porcentaje, la verificacion de piezas nuevas como parte de los procesos de manufactura. Esta actividad se apoya en el uso de dispositivos conocidos como fixtures, cuyo equipo y herramienta obliga a los operarios a levantar cargas entre los 10 y los 50 kilogramos, realizando operaciones manuales para la sujecion de piezas, presentandose dolores a nivel lumbar, por lo que es primordial medir los riesgos de lesiones en la espalda de la poblacion en estudio. El objetivo fue identificar y medir los riesgos de lesiones en la espalda de la poblacion en estudio. Materiales y metodos: se analiza el proceso de inspeccion identificando los factores de riesgo potencial. Se utilizan metodologias y herramientas ergonomicas, tales como Quick Exposure Check (QEC), la ecuacion del National Institute for Occupational Safety and Health (Niosh), el metodo REBA (Rapid Entire Body Assessment), el sistema de analisis de posturas de trabajo de Ovako (owas), entre otras. Resultados: el metodo QEC muestra que tronco/ espalda y muneca/mano son las partes mas sensibles a la exposicion de riesgo, senalando el 18 % de las posturas en un nivel de riesgo 4, con la espalda rotada y flexionada en mas del 32 % del tiempo. El peso que conlleva la operacion supera los 20 kilogramos en el 71,4%. Conclusion: se utilizan cuatro tecnicas ergonomicas para evaluar el riesgo de lesion y se analiza el proceso de inspeccion de piezas fabricadas. EnglishIntroduction: The Mexican manufacturing sector in the automotive industry employs an average of 8 million 850 thousand workers per year spread across the 32 states, of which Puebla contributes with 465 106, developing, in a high percentage, the verification of new parts as part of the manufacture process. This activity is supported by the use of devices known as fixtures, whose equipment and tool forces operators to lift loads between 10 and 50 kilograms by performing manual operations to hold parts, presenting pain at the lumbar level, therefore, it is essential to measure the risks of back injuries in the study population. The objective was to identify and measure the risks of back injuries in the study population. Materials and methods: The inspection process is analyzed by identifying the potential risk factors. Ergonomic methodologies and instruments are used, such as Quick Exposure Check (QEC), the National Institute for Occupational Safety and Health (Niosh) equation, the reba (Rapid Entire Body Assessment) method, Ovako’s Work Posture Analysis System (OWAS), among others. Results: The qec method shows that trunk/back and wrist/hand are the most sensitive parts to risk exposure, indicating that 18 % of the postures are rated 4 in the level of risk, with the back rotated and bent in over 32 % of time. The weight of the operation exceeds 20 kilograms in 71.4 %. Conclusion: Four ergonomic techniques are used to assess the risk of injury, the inspection process of manufactured parts is analyzed. portuguesIntroducao: a industria manufatureira mexicana do ramo automotivo emprega em media 8 milhoes 850 mil trabalhadores ao ano repartidos nos 32 estados, dos quais Puebla contribui com 465 106 deles, desenvolvendo, em uma alta porcentagem a verificacao de pecas novas como parte dos processos de manufatura. Esta atividade apoia-se no uso de dispositivos conhecidos como fixtures, cuja equipe e ferramentas abriga aos operarios a levantar cargas entre os 10 e 50 quilogramas realizando operacoes manuais para a fixacao de pecas, se apresentando dores no nivel lombar, pelo que e primordial medir os riscos de lesoes nas costas da populacao em estudo. Materiais e metodos: se analisa o processo de inspecao identificando os fatores de risco potencial. Se utilizam metodologias e ferramentas ergonomicas, tais como Quick Exposure Check (QEC), a equacao do National Institute for Occupational Safety and Health (Niosh), o metodo REBA (Rapid Entire Body Assessment), o sistema de analise de posturas de trabalho de Ovako (OWAS), entre outras. Resultados: o metodo QEC mostra que o torso/costas e o pulso/mao sao as partes mais sensiveis a exposicao de risco, assinalando o 18 % das posturas em um nivel de risco 4, com as costas rotadas e curvadas em mais do 32 % do tempo. O peso que leva a operacao supera os 20 quilogramas no 71.4 %. Conclusao: utilizam-se quatro tecnicas ergonomicas para avaliar o risco de lesao e se analisa o processo de inspecao de pecas fabricadas.
