A biomechanical study of physical exposures on jobs in three high risk industries in Washington State

Abstract [en]

Physical exposures in three high-risk industries in Washington State (USA) were quantified biomechanically using a 3D SSPP biomechanical model. Seventy male workers were selected on the basis of awkward work postures adopted while performing tasks. Videotaping and observation methods were used to collect data. The 3D SSPP modelled 229 video frames of work postures from the sawmills, air transportation and food processing industries that had volunteered for this study. A paired t-test was used to compare sample means of exposure variables in order to verify any variations among jobs within industry and between industries. The results showed that there are significant differences in exposure variables (compression and shear forces, strength capacities in elbow, shoulder and torso joints). The awkward work postures performed by the workers studied seem to stem from poor work process design, most of the recommendations were shared with industries to reduce the biomechanical loading shown in the study.
