Ergonomic Risk Assessment and Mitigation Strategies for Retail Workers: Insights from a Case Study in Dungun

Abstract

Manual handling activities contribute to 40% of musculoskeletal disorders (MSDs), leading to long-term discomfort, disability, medical costs, and financial hardships for workers, while employers face lower productivity and compensation costs. An ergonomic assessment was conducted among employees at ABC Hardware in Dungun to identify ergonomic risk factors, determine the likelihood of harm affecting workers' musculoskeletal health, and recommend control measures to improve workers' health and well-being. Utilizing a combination of interviews, observations, and questionnaires based on established ergonomics guidelines, the research highlights the prevalence of MSDs among workers engaged in manual handling tasks, emphasizing the need for ergonomic interventions and awareness to enhance workplace safety and employee well-being. Findings from the ergonomic assessment revealed significant discomfort and risk factors related to awkward postures, repetitive motions, forceful exertion, and static positions. Specific ergonomic issues identified include discomfort in the upper back, thighs, and knees among storekeepers, and neck and lower back pain among warehouse workers. Service desk representatives were found to experience discomfort related to static postures and repetitive motions. The study recommends advanced ergonomic assessments such as Rapid Entire Body Assessment (REBA), Occupational Repetitive Assessment (OCRA), and Rapid Upper Limb Assessment (RULA), along with improvements in ergonomic practices and tools. Implementing job rotation, providing ergonomic equipment, and conducting training on proper lifting techniques are essential to address the identified risks. This research highlights the critical role of ergonomic practices in preventing MSDs and improving overall workplace safety.
