| description | The work in the sawmill industry is physically demanding because it is performed under unhealthy body postures that generate musculoskeletal injuries and its study requires risk assessment tools to identify the most serious. In the sawmills of El Salto, Durango, Mexico, the level of risk of the work positions in people is unknown; therefore, the objective of this study was to perform a postural analysis in 15 workplaces. From 7.5 hours of video that considered effective work in the workplace, 900 still images were obtained at 30-second intervals to analyze them using the OWAS method. The global index of postural risk was estimated and contingency tables and association tests between categorical variables of chi square were elaborated. The results showed a frequency of postures of 48% with risk levels 2, 3 and 4, indicating actions for postural correction for risks 2 and 3 as well as immediate modifications for the 4. The global risk index was established at 166 points cataloged as minimum. By workplace, the workers in the manual logs handling and manual stacking and carriage of lumber are the most susceptible to present injuries with global risk indexes above 200 points. By body area, 43% of the positions of the back and 40% of the legs are in a level risk 2 considered as not harmful, and 100% of the positions of the arms resulted with a level risk 1 not requiring any modification. |

El trabajo en la industria del aserrío es físicamente exigente porque se realiza bajo posturas corporales poco saludables que generan lesiones musculoesqueléticas y su estudio requiere de herramientas de evaluación de riesgos para identificarlas adecuadamente. En los aserraderos de El Salto, Durango, México se desconoce el nivel de riesgo de las posturas de trabajo en las personas, por lo que el objetivo de este estudio fue realizar un análisis postural en 15 puestos de trabajo. A partir de 7.5 h de video, que consideraron el trabajo efectivo en los puestos laborales, se obtuvieron 900 imágenes fijas a intervalos de 30 segundos para analizarlas mediante el método OWAS. Se estimó el índice global de riesgo postural y se elaboraron tablas de contingencia y pruebas de asociación entre variables categóricas de Chi-cuadrado. Los resultados mostraron una frecuencia de posturas de 48% con nivel de riesgo 2, 3 y 4, indicando realizar acciones de corrección postural para los riesgos 2 y 3 así como modificaciones inmediatas para el 4. El índice global de riesgo se estableció en 166 puntos catalogado como mínimo. Por puesto de trabajo, los topadores y volteadores son los más susceptibles de presentar lesiones musculoesqueléticas con índices globales de riesgo por encima de los 200 puntos. Por zona corporal, 43% de las posiciones de la espalda y 40% de las piernas se encuentran en un nivel de riesgo 2, considerado como poco dañino, y 100% de las posiciones de los brazos resultaron con un nivel de riesgo 1 que no requiere modificación alguna.
