Optimized manual lifting condition amongst workers using an ergonomics guidelines

A case study

Research output: Contribution to journalArticle

Abstract

Background: Assessment on working posture during manual lifting is very important to ensure the task is safe. Lifting task is acceptable if it can satisfy certain ergonomic requirements. This study aims to identify the body part discomfort while performing the manual handling task and to evaluate the major manual lifting tasks in a printing factory.

Method: A semi structured interview was conducted with six workers from the factory to gather information regarding the body part discomfort and assessment on current manual handling activity by using Body Part Discomfort Survey (BPDS) and Occupational Manual Handling Task Assessment (OMHTA). Then, three selected manual handling tasks were recorded and then were transferred to Vision Assisted Anthropometric Measurement Systems (VAAMS) to measure the worker’s posture and the workstation dimensions. A manual calculation by using Manual Lifting Task Analysis Chart (MLTAC) was performed to find the potential problem of the task.

Results: The findings from the BPDS showed majority of the manual workers had experienced back discomfort. Meanwhile, based on the MLTAC, the Lifting Index value showed that there were two cases of manual handling tasks that need to be redesign.

Conclusion: In order to redesign the task, improvements on current task was conducted by manipulating the weight of the object lifted, improvement of hand to object coupling, manipulation of horizontal and vertical distance, reduction in the lifting frequency rate, reduction in the angle of symmetry, work duration and work station.
