Abstract: Office ergonomics provides an arbitrary framework for integrating a large body of research that is relevant to the design of office work environment to optimize the health, safety, comfort, and effectiveness of human occupants . This paper involves office workers in the Faculty of Engineering Technology (FTK) at Universiti Tun Hussein Onn Malaysia (UTHM). The main objective of this paper is to determine the risk level of the office designed during the working daily time using Rapid Office Strain Assessment (ROSA) technique. This paper applied ROSA technique for estimating the risk factor exposure in office workers. A set of questionnaires consisting items on working experience, work-related posture, and work-related pain was distributed to a total of forty (40) respondents among office workers from FTK UTHM. It was found that seventy–five percent (75%) of respondents had work-related pain in their part of body such as the neck, shoulder, wrist, lower back, hip, and knee. Besides, the significant level risk of respondent B and C were deemed high-risk; five (5) and six (6) scores, respectively, implying that respondents’ workstations should be evaluated further in terms of office ergonomic design. Therefore, it is suggested in this study that when designing a workstation, the principle of motion economy be taken into account to ensure that the standard assessment is met.
