CHAPTER 2 LITERATURE REVIEW 2.1 Introduction Ergonomic is an important thing to be considered in making sure that the workplace is safe from any factors ok risk that causes injuries to the employees. The term ergonomics has its roots in Ramazzini’s study of the ill-effects of poor posture and poorly designed tools on the health of workers in the early 1700s (Byers et al., 1978). Ergonomics is the study of work laws. it goals is to fit work to employees, rather than fitting workers to the work, through developing knowledge that outcomes in productive adjustment of work techniques to the individual's physiological and mental qualities. The mission of the ergonomics practitioner is to identify and reduce those work stresses that affect the safety,…show more content…
The term ergonomics is derived from two Greek words, ergo (work) and nomikos (law). Ergonomics can be defined as “that branch of science that is concerned with the achievement of optimal relationships between workers and their work environment”. According to F. Tayyari and J.L. Smith (1997), "ergonomic deals with the assessment of the human's capabilities and limitations (biomechanics and anthropometry), work and environment stresses (work physiology and industrial psychology ), static and dynamic forces on the human body structure (biomechanics), vigilance (industrial psychology), fatigue (work psychology and industrial psychology), design simulation and training, and design the workstations and tools (anthropometry and engineering)". In addition, Shaliza (2009) stated that “Ergonomic deals with the application of information about human behavior, capability and limitation to the design of systems, machines, tools, tasks or jobs and environments for productive, safe and effective human use”. All knowledge about ergonomic can be used to get better understanding about the correlations between human, machine and workstations. If the proper design of the workplace can be achieved, it will ensure the safety, health, and comfort of the workers thus reducing the risks of injuries and…show more content…
Step 13: Add the muscle use score to this box. For this example, the posture is not sustained for more than 10 minutes, and not repeated 4x per minutes. Thus, the score is 0. Step 14: For this case, it is assumed that the load is greater than 4.4 lbs and repeated. Therefore, the score is +2. Step 15: Add the values is steps 12-14 to obtain the Neck, Trunk and leg Group B score. How to determine final RULA score In order to determine the final RULA score, we need to use one more table which is Table C as shown below. Figure 5: Determining RULA Score Thus, after using all values obtained from step ‘wrist & arm score’ and ‘neck, trunk & legs score’, locate the score in Table C. Hence, the final RULA score = 7. In DELMIA V5 software, we can evaluate the score automatically by setting up the parameters required and the score are given in numbers and colors. The basic mode of the RULA analyses presented in the Delmia V5© program displays its final score in the form of colored zones and numerical values ranging from 1 to 7. • 1 and 2: (Green) Indicates that the posture is acceptable if it is not maintained or repeated for long periods of
