Abstract

|
|
The aim of this study was to evaluate the prevailing ergonomic conditions regarding low back injury in an assembly factory. In this study, analytic biomechanical model and NIOSH guidelines were applied to evaluate risk levels of low back injury for automobile assembly jobs. Total of 246 workers were analysed. There were 10 jobs with greater back compressive forces than 350㎏ at L5/Sl. Also there were 44 jobs over Action Limit in terms of 1981 NIOSH guidelines. This could in part be explained by the ergonomic conditions of the companys analysed as not hazardous, with a relatively low duration of ´combined´ extreme work posture. However, more ergonomic intervention could be done based an those results.
