In Malaysia, studies have shown that low employee performance occurs due to accidents, health problems and stress at work. This situation affects the performance of the organization, reduces the quality of work, increases the cost of workers' compensation and ultimately interferes with the development of the organization and the growth of the national economy. This study aims to examine the level of employee awareness of ergonomic risk factors and occupational safety and health performance. A total of one hundred and fortyfive respondents from several manufacturing companies in the state of Selangor, Malaysia were analyzed through distributed questionnaires. Five dimensions are involved as independent variables to measure ergonomic risk factors, namely awkward posture, static work posture, repetitive movements, vibration and physical environment while safety and health performance as a dependent variable is measured through occupational pain, job stress and occupational accidents. The study found that ergonomic risk factors affect occupational safety and health performance in the workplace. The results of the study stated that the emphasis on ergonomic risk factors should be emphasized in order to improve occupational safety and health performance. This element is not only able to increase the productivity of the organization but is also able to provide benefits especially to the manufacturing sector as a guideline in implementing measures to prevent occupational accidents, occupational pain and occupational stress.
