4 Human Kinetics and Ergonomics Certificate in Ergonomics Short Course Background In 2012 the Department of Labour (DoL) hosted the Occupational Health and Safety Conference: Road to zero injuries and accidents at which the topic of Ergonomics was discussed. Since then the DoL has invested a significant amount of time and energy into getting ergonomics regulations promulgated within South Africa and giving the discipline the recognition that it deserves. Significant progress has been made and the Ergonomics Technical Committee has developed an excellent working document for the regulations. An important step in ensuring that the regulations can be successfully implemented is providing the DoL Occupational Health and Safety inspectorate with sufficient education in Ergonomics. Within this context, the DoL has approached Rhodes University and more specifically the Department of Human Kinetics and Ergonomics (HKE) to develop such a course. The HKE Department is currently the sole provider of undergraduate and postgraduate education in Ergonomics in South Africa and is consequently perfectly situated to perform this role. Furthermore, the staff in the department are intrinsically involved in ergonomics both within the South African and the international ergonomics community. To ensure that the course provided is of the highest quality the HKE department has worked closely with the Professional Affairs Board (PAB) of the Ergonomics Society of South Africa (ESSA). The short course is consequently aligned with the PAB board constitution in terms of the recognized levels of professionalism within Ergonomics. Course Description This short course forms an introduction to the principles of ergonomics and to ergonomics risk assessment in a variety of situations, including, but not limited to construction, manufacturing, mining, transport etc., in the South African context. It provides a framework of knowledge covering the breadth and width of basic ergonomics risk assessment and will provide sufficient education for participants to register as a Certified Ergonomics Associate (CEA) with the Professional Affairs Board of the Ergonomics Society of South Africa. As such, participants who successfully complete this course will have the following capabilities that are aligned with the requirements for a CEA: A Certified Ergonomics Associate (CEA) is an interventionist who applies a general breadth of knowledge to analysis and evaluation of currently operating work systems. The scope of practice of a CEA is limited to the use of commonly accepted tools and techniques for the analysis and enhancement of human performance in existing systems. A CEA may, for example, be responsible for the co-ordination of an Ergonomics Facilitation team within their own industry to create an awareness of Ergonomics, to identify problems, to implement basic solutions and to recognise when to consult a CPE (Professional Affairs Board Charter, 2014). 4

5 Course Structure The course is structured in a manner that complies with the guidelines outlined in the PAB charter for recognition as a CEA with the Ergonomics society. Participants will thus have to complete 360 hours of work across six modules of 60 hours each. These hours will be comprised of contact time with the various lecturers, self-directed learning and assignments. In order for the course to be recognized by both Rhodes University and the ergonomics society, it is necessary to examine the key competences of each module. Each module mark consists of a class mark obtained via an assignment conducted or test written at the end of each module, as well as a mark from a take-home assignment, which participants complete in their own time and in a work context of their choice and submit prior to the start of the next module. Furthermore, the final module (Module 6) requires the participants to submit a comprehensive portfolio of work performed during the course, in which they demonstrate their understanding of ergonomics theory as well as their practical competence in applying such principles in a workplace. This portfolio can form the basis of the evidence needed to apply for certification with the Ergonomics Society of South Africa s (ESSA) Professional Affairs Board (PAB). To ensure that the course complies with the guidelines established by the PAB charter for a CEA the course will be comprised as follows: Module: Break down of allocation Total time allocation Principles of Ergonomics and Principles of ergonomics (20 hrs) 60 hours Ergonomics Risk Assessment Principles of risk assessment (40hrs) Human Characteristics Biology of Ergonomics (40 hours) Task-operator interaction (20 hours) 60 hours Assessment of Manual 60 hours 60 hours Materials Handling Tasks, Repetitive Activities and Working Postures Office and Control Tasks Office environment (20 hours) Inspection tasks (20 hours) Human Error (20 hours) 60 hours Professional issues and 60 hours 60 hours implementation Portfolio 60 hours 60 hours Assumptions of Prior Learning In order to register to participate in the course it is necessary to have a diploma or an undergraduate degree from a recognized institution in a cognate discipline, for example, medicine, biokinetics, physiotherapy, engineering, industrial design, health and safety etc. Mode of Delivery The mode of delivery for the course will include a diverse range of learning environments including, but not limited to, lectures, discussions, practicals, self-directed learning and 5

6 assignments. Each module will have its own unique delivery characteristics depending on the needs of the particular module. Estimated maximum time for the course Each module of the course will require 60 hours from the participants, with a total of 360 hours for all six modules. These hours will include a diverse range of tasks from contact time with course and module co-ordinators, self-directed learning and various assignments. These hours include the time required to access the materials, self-directed learning and reading, assessments and assignments, as well as the final portfolio for assessment. How is the Course run? A timetable is provided to the participants ahead of each module. Course materials will be sent to participants prior to the course. Depending on the module, there will be the option for the module to be run at a) Rhodes University in the Human Kinetics and Ergonomics department and b) at remote locations around the country. Please see the specific modules for details in this regard. There will obviously be cost implications for the various options undertaken here. Intended Outcomes The intended learning outcomes (stated within the module guidelines) are assessed by assignments and tests. Participants will be required to obtain an average mark of 50% in order to pass the course. Intended Learning Outcomes for the Course Each module has clearly stated learning outcomes that the participants will need to engage with. However, there are also learning outcomes that are generic to the course as a whole and transcend the individual modules. These are referred to as critical cross-field outcomes (CCFOs) which are outlined below: Mastery of concepts and development of core information in disciplines not previously studied Time management Computing skills Access and retrieval of information Basic data analysis techniques Communication with peers about ergonomics, ergonomics assessments, human capabilities, task/operator interaction and human-task interaction via presentations and report writing. How is the Course assessed? In order for the qualification to be recognized by Rhodes University and by the PAB of the Ergonomics Society of South Africa, it is not only necessary for the students to have participated in the course, but also to have demonstrated competence through the assignments and various tests/exams conducted during each module. Participants will be 6

16 Module 4: Office and Control Tasks Description The purpose of this module is to develop individuals who possess a thorough understanding of tasks that occur in office and control room environments. In both types of work, employees are seated for most of the work period and perform predominantly cognitively-based tasks. Ensuring that operators adopt the most appropriate body posture is critical and is achieved through the inclusion of appropriate workspace design. Additionally, adequate environmental conditions such as lighting and ventilation are essential to avoid detrimental long-term effects on the physical and mental capacity of office workers. Task demands need to match the human capabilities in terms of perception, concentration and the need for sustained attention. This balance will limit employee fatigue, ensuring that work performance is sustained. Intended Learning Outcomes for the Module Participants will: Understand ergonomics factors of office workplaces, with focus on appropriate environmental, seating and furniture arrangements. Assess office workplaces with respect to ergonomics and identify the potential for basic improvements/control measures, Understand the nature of cognitive tasks and their impact on health risks and human performance, particularly with respect to human reliability and inspection tasks, and Assess tasks with specific demands on human reliability and inspections tasks with respect to ergonomics, and identify potential for basic improvements/control measures. Assumptions of Prior Learning: Participants should: Have experienced some forms of working in an office environment Have knowledge and understanding of musculoskeletal anatomy, as well a basic knowledge of physiology, biomechanics and ergonomics. Have knowledge and understanding of basic physical and mathematical terms (e.g. forces and levers). Be capable of accessing additional information from books, journals, internet sources. 16
