Ergonomics And Safety In Hand Tool Design

This book focuses exclusively on ergonomics in the design and use of hand tools. Hand tools have been an integral supplement to the human hand since the beginning of civilization. Recently, they have been pinpointed as a prominent cause of workplace disease. Cumulative Trauma Disorders such as Tendonitus, Carpal Tunnel Syndrome, and Raynaud's Syndrome are caused by the specialization of motion employed when using a screw driver, the shock to the hand and wrist when a hammer strikes a nail, or the vibration of a power saw. Ergonomics and Safety in Hand Tool Design explores the relationship between Biomechanics, Safety, and Ergonomics allowing the reader to recognize, evaluate, and control ergonomic risk factors and improve hand tool design. After a history of hand tool use and design, the book is broken down by the various disciplines as they apply to hand tools, taking a broad approach. The author gives special attention to safe design and use, illustrated with detailed diagrams. The text serves as a guide to the human factors in safety and ergonomics for safety professionals.

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.

The ergonomics focus is on how to design work tasks, tools, and environments to fit the capabilities and limitations of people. Ergonomic Design for Material Handling Systems describes how ergonomics can be applied specifically to load handling, both in the original design of systems and in their modification to make jobs easier and safer. Proven techniques (such as flow charting, or job analysis) are combined with new considerations (such as biomechanics and repetitive trauma) to optimize facility, work station, equipment, and job procedures. Ergonomic Design for Material Handling Systems shows how ergonomics overlaps and intertwines with traditional engineering and management, uniting them to produce ease and efficiency in material handling. This book demonstrates how to lay out facilities in order to achieve the most efficient and safe design. It tells how to organize tasks, machinery, people, and materials to improve work flow and "humanize" your workplaces. Consideration of human needs and abilities contributes essentially to successful performance-let this practical book be your guide.

As the ergonomic aspect of many problems facing the industry today attracts more attention from the management, providing scientific knowledge and the know-how to solve such problems is becoming increasingly more important. The impetus for this book originated from the pressing need to make the state-of-the-art ergonomic information on workspace, equipment and tool design available to practising ergonomists, safety specialists, engineering designers, and business and technical managers. The book reinforces the notion that ergonomic data should be explicitly integrated in the design of a system, and should become an indispensable part of the overall design process in production engineering, on an equal basis with such activities as mechanical component design, quality assurance, maintenance, inspection, etc. The focus is on selected ergonomic data for workspace, equipment and tool design, with special emphasis on the practical aspects of applying the available information to specific problem areas.

Prepared in collaboration with the International Ergonomics Association, this book presents a compilation of 128 illustrated ideas which identify practical and inexpensive solutions to ergonomic problems in the workplace. The checkpoints can be used either to check working conditions on the spot or at the design stage, and are suited to a wide variety of premises. Each checkpoint indicates an action, explains why it is necessary, gives advice on its implementation and other relevant information. Ergonomic issues covered include: materials storage and handling; hand tools; machine safety; improving workstation design; lighting; premises; control of hazardous substances; welfare facilities; and work organisation.

The approach to the book is analogous to a toolkit. The user will open the book and locate the tool that best fits the ergonomic assessment task he/she is performing. The chapters of the book progress from the concept of ergonomics, through the various assessment techniques, and into the more complex techniques. In addition to discussing the techniques, this book presents them in a form that the readers can readily adapt to their particular situation. Each chapter, where applicable, presents the technique discussed in that chapter and demonstrates how it is used. The supporting material at the end of each chapter contains exercises, case studies and review questions. The case study section of the book presents how to use techniques to analyze a range of workplace scenarios. Topics include: The Basics of Ergonomics; Anthropometry; Office Ergonomics; Administrative Controls; Biomechanics; Hand Tools; Vibration; Workstation Design; Manual Material Handling; Job Requirements and Physical Demands Survey; Ergonomic Survey Tools; Work-related Musculoskeletal Disorders; How to Conduct an Ergonomics Assessment; and Case Studies
