Abstract
Introduction: Ergonomics is a major issue in the manufacturing industry. A physical factor in the environment that harms the musculoskeletal system is referred to as an ergonomic hazard. Therefore, workers in industrial industries have a severe health concerns due to work-related musculoskeletal disorders (WMSDs). This symptom is now existent and has a detrimental impact on occupational health, resulting in worker impairment and lost wages. Work conditions that can cause Work-Related Musculoskeletal Disorder (WMSD) include routine lifting of heavy objects, daily exposure to whole-body vibration, routine overhead work, working with the neck in chronic flexion, and performing repetitive forceful tasks. This study used questionnaires and observations to determine the most ergonomic risk factors and the prevalence of WMSDs among paint manufacturing workers in order to identify and reduce the safety and health risks associated with the manufacturing task while maintaining user productivity. Objective: This study aimed to determine the prominent ergonomic risk factors and the prevalence of WMSDs among workers in paint manufacturing industries in Shah Alam. Methodology: This study was conducted among workers in a paint manufacturing factory. The selection of workstations was done by a stratified sampling method. A self-administered Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was used to assess musculoskeletal discomfort among workers. In addition, Initial Ergonomic Assessment (ERA) was performed to all four departments to identify the prominent ergonomic risk factors that exposed to the workers. The self-administered questionnaire data was analyzed for descriptive analysis, chi square test and logistic regression test using The Statistical Package for Social Sciences Software (SPSS) Version 27. Results: A total of 130 workers participated in this study. Four work unit that represent all departments at the paint manufacturing factory shows that the prominent ergonomic risk factors had been identified were awkward posture, static and sustained work posture, forceful exertion and repetitive motion. The prevalence of WMSDs among workers in the paint manufacturing factory was 58.5% and the highest WMSDs complaint being self-reported for neck was (40.8%) WMSDs followed by right shoulder (28.5%), upper back (17.7%) and left shoulder (11.5%) respectively. Next, in this study, was found that there were few ergonomics risks factors that significantly associated with WMSDs in any part of the body as neck at p<0.05 such as awkward posture (p<0.001, OR=27.133), static and sustained work posture (p= 0.004, OR=2.985), forceful exertion (p= 0.033, OR=0.394) and repetitive motion (p= 0.033, OR=2.538). Discussion: This study revealed that there was a significant relationship (p<0.05) between the prominent ergonomic risk factors and the prevalence of WMSDs among workers in the paint manufacturing factory. Multiple logistic regression test showed that workers who were exposed to awkward posture had 27 times more likely which is the highest to develop WMSDs compared to static and sustained work posture and repetitive motion. Conclusion: There were four prominent ergonomic risk factors of the work tasks performed by workers in paint manufacturing factory which were awkward posture, static and sustained work posture, forceful exertion and repetitive motion. The ergonomic risk factors that were highly associated with the prevalence of WMSDs were awkward posture, static and sustained work posture, forceful exertion and repetitive motion. Thus, further research may focus on conducting Advanced Ergonomic Risk Assessment (ERA) since the body parts affected in this study were the upper limbs. It is recommended to use Rapid Upper Limb Assessment (RULA) to evaluate the exposure of individual workers to ergonomic risk factors associated with upper extremity MSD. Keywords: Work-Related Musculoskeletal Disorders, Ergonomic Risk Factors, Cornell Musculoskeletal Discomfort Questionnaire.
