Topics Include: applications of engineering anthropometry, postural strain and discomfort, industrial injury prevention, manual materials handling, and ergonomics of rehabilitation and healthcare systems.
Ergonomics touches every man, woman and child each day of their lives whether they recognise it or not. Ergonomics (or lack of it) plays a more significant role in the lives of about two-thirds of the world s population over 10 years of age who work for one-third of their lives to make a living. There are 120 million occupational accidents and injuries and 200,000 fatalities each year according to WHO 95. Occupational accidents, injuries and fatalities are undesired events. The occupational activities are planned and designed, and executed with a purpose under supervision but accidents are not. Hence it stands to reason that better planning, design and execution will help to reduce these undesirable outcomes. One must also recognise that under global scheme of biological evolution, the human beings were not designed to endure a life long exposure to artificial activities repetitively. Thus occupational health problems are inevitable if we do not return to nature for our sustenance. As a society, we have chosen to live and work as we do. In fact, there is a far rapid evolution (mutation and speciation) of occupations than of any biological organism. This places us in a situation where better planning, design and execution of our occupational activities have become absolute necessity. However, since ergonomics is a modifier and not a causal factor, its significance does not become immediately apparent to us. Perhaps it is for this reason that even in developed world occupational health services are available to between 20% to 50% of the work force and less than 10% of the workforce in the developing countries. Occupational health services are remedial approaches. The rational wisdom of the human race should strive to get proactive control of undesirable outcomes through ergonomics. Unfortunately, it is sadly lacking even today. On an optimistic note one can observe that its presence and application is slowly increasing.
Topics Include: industrial ergonomics, risk, accidents and accident prevention, safety and surveillance, posture perception, cognitive ergonomics, telerobotics, military occupational ergonomics, and international ergonomics.
Occupational ergonomics and safety studies the application of human behavior, abilities, limitations, and other characteristics to the design, testing, and evaluation of tools, machines, systems, tasks, jobs, and environments for productive, safe, comfortable, and effective use. Occupational Ergonomics Handbook provides current, comprehensive knowledge in this broad field, providing essential, state-of-the-art information from nearly 150 international leaders of this discipline. The text assesses the knowledge and expertise applied to industrial environments: Providing engineering guidelines for redesigning tools, machines, and work layouts Evaluating the demands placed on workers by current jobs Simulating alternative work methods Determining the potential for reducing physical job demands based on the implementation of new methods Topics also include: Fundamental ergonomic design principles at work Work-related musculoskeletal injuries, such as cumulative trauma to the upper extremity (CTDs) and low back disorders (LBDs), which affect several million workers each year with total costs exceeding $100 billion annually Current knowledge used for minimizing human suffering, potential for occupational disability, and related worker's compensation costs Working conditions under which musculoskeletal injuries might occur Engineering design measures for eliminating or reducing known job-risk factors Optimal manufacturing processes regarding human perceptual and cognitive abilities as well as task reliability Identifying the worker population affected by adverse conditions Early medical and work intervention efforts Economics of an ergonomics maintenance program Ergonomics as an essential cost to doing business Ergonomics intervention includes design for manufacturability, total quality management, and work organization. Occupational Ergonomics Handbook demonstrates how ergonomics serves as a vital component for the activities of the company and enables an advantageous cooperation between management and labor. This new handbook serves a broad segment of industrial practitioners, including industrial and manufacturing engineers; managers; plant supervisors and ergonomics professionals; researchers and students from academia, business, and government; human factors and safety specialists; physical therapists; cognitive and work psychologists; sociologists; and human-computer communications specialists.
Occupational Ergonomics: Engineering and Administrative Controls focuses on prevention of work-related musculoskeletal disorders with an emphasis on engineering and administrative controls. Section I provides knowledge about risk factors for upper and lower extremities at work, while Section II concentrates on risk factors for work-related low back disorders. Section III discusses fundamentals of surveillance of musculoskeletal disorders, requirements for surveillance database systems, OSHA Record keeping system, and surveillance methods based on the assessment of body discomfort. Section IV focuses on medical management of work-related musculoskeletal disorders, including programs for post-injury management, testing of physical ability for employment decisions, assessment of worker strength and other functional capacities, and applications of ergonomics knowledge in rehabilitation.
The International Ergonomics Association (IEA) is currently developing standards for Ergonomic Quality in Design (EQUID) which primarily intends to promote ergonomics principles and the adaptation of a process approach for the development of products, work systems and services. It is important to assess the ergonomic quality of products, hand-held tools and computer input devices through working processes that represent reality. Well-designed working tools can be expected to reduce or eliminate fatigue, discomfort, accidents and health problems and they can lead to improvements in productivity and quality. Furthermore, absenteeism, job turnover and training costs can positively be influenced by the working tools and the environment. Not all these short-term and long-term issues of working tools can be quantified in pragmatically oriented ergonomic research approaches. But multi-channel electromyography, which enables the measurement of the physiological costs of the muscles involved in handling tools during standardized working tests, and subjective assessments of experienced subjects enable a reliable insight in the essential ergonomic criteria of working tools and products. In this respect it is advantageous to provide a test procedure, in which working tests can be carried out alternating both with test objects and reference models.
Completely revised and updated, taking the scientific rigor to a whole new level, the second edition of the Occupational Ergonomics Handbook is now available in two volumes. This new organization demonstrates the enormous amount of advances that have occurred in the field since the publication of the first edition. The editors have brought together
Electromyography (EMG) is the study of muscle behaviour via electronic means, and is thus a technique fundamental to ergonomics, physiology and biomechanics. This text describes the principles of EMG and its application domains, focusing on anatomy, biology, muscle characteristics, physics, mechanics, EMG signal, noise/artifacts/errors, equipment/devices/techniques, interpretation and computerised data acquisition, and analysis. The book provides a theoretical base, a strategic framework and user experiences.
