Risk of upper extremity biomechanical overload in automotive facility. | LitMetric
Objective : To assess the risk factors for upper extremity-work-related musculoskeletal disorders (UE-WMSD) on 13 production lines in an airbag factory using the threshold limit values-American conference of industrial hygienists- hand activity level (TLV-ACGIH-HAL) method and introduce the ergonomic improvement to reduce the repetitiveness and the peak force (Pf).Methods : Professional exposure level on 13 production lines in a automobile factory was measured using the TLV-ACGIH-HAL method and a further risk was assessed according to the ergonomic improvement.Results : The first assessment of 9 production lines showed that the professional exposure level was above the TLV or HAL limit. The second assessment showed that the professional exposure level was below the AL limit on all production lines except 1, in which the professional exposure level was between TLV and HAL.Conclusion : The assessment of UE-WMSD-related risk can identify the riskiest emplacements and evaluate the reduction of risk in professional exposure through interventions of structural- organizational type.
