Ergonomic Risk Assessment on Welding Practical Work on learning process at Malaysia polytechnic diploma of engineering programme

Abstract

Practical work is part of the compulsory process of learning for any engineering student in polytechnic Malaysia. This study focuses on the ergonomic risk assessment during the practical work for Malaysian Polytechnic for mechanical diploma programme. Consequently, it is also implemented to identify potential harm caused by ergonomic risk factors. This study uses quantitative method through the Cornell Musculoskeletal Discomfort Questionnaire (CMQ) framework and is followed by a Rapid Entire Body Assessment (REBA). The instruments used are measuring tape, smartphones for recording audio and video as well as digital images, assessment checklists (CMQ and REBA), personal protective equipment, goniometers and weights scale. Based on the study, all elements of value provide high level risk score results and require ergonomic risk control. Therefore, it is recommended to review the body's posture and improve the techniques during the weld practical work process to reduce ergonomic risk factors.
