Download or read book Wiring Regulations in Brief written by Ray Tricker and published by Routledge. This book was released on 2007-02-07 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: This essential reference will prove an invaluable guide for anyone based in the electrical industry working on electrical systems (design, installation, inspection and testing), who requires a comprehensive source of information on the specific requirements of the IEE Wiring Regulations (published by the IET), without having to trawl through the lengthy, complicated coverage of the Regulations themselves. Unlike the majority of texts available on the subject of the IEE Wiring Regulations, which explain how adherence to the Regulations is achieved in working practice, Ray Tricker presents the specifics of the actual regulatory Standard itself in his renowned, easily accessible, and informal writing style. Wiring Regulations in Brief presents the IEE Wiring Regulations with a unique topic-based approach. Unlike the Regulations themselves, related topics are linked – areas such as inspection and testing are presented together in one section. This provides the reader with an exceptionally quick source of reference on all aspects of the Regulations as they relate to a specific area of working practice, which maximises easy identification of practical problems, and Regulations compliance. Part P, which brings domestic electrical installations under Building Regulations control as of 2005, is also covered in detail, to highlight the requirement that any person who carries out domestic electrical installation work, is now legally required to demonstrate their competence in their area of work.

Download or read book Safety at Work written by John Ridley and published by Routledge. This book was released on 2004-02-18 with total page 1092 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety at Work is widely accepted as the authoritative guide to safety and health in the workplace and covers all aspects of safety management. The sixth edition has been revised to cover recent changes to UK practice and standards in health, safety, employment and environmental legislation. It also incorporates EU directives and references to harmonised and international standards. Reflecting the importance of the roles of directors and managers in health and safety, new chapters cover the management of risk, emphasising the need for a sound organisational structure to achieve effective risk management. Developments in the behavioural approach to risk management and current thinking on the development of an international standard on safety management are also covered. Quality of the environment is rapidly becoming part of the safety manager’s responsibilities both in the workplace and in the context of global pollution. A completely new part consisting of five chapters has been added dealing solely with environmental issues (including ISO 14001). The increasingly important role of ergonomics in health and safety is reflected in a new chapter on Applied Ergonomics, dealing with the subject pragmatically, that will allow the manager and practitioner to design process and operations that are within the limits of the human body. The effects of stress, an emerging concern in health and safety, are covered in various chapters.

Download or read book Electrical Safety and the Law written by John M Madden and published by Routledge. This book was released on 2017-01-20 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrical Safety and the Law describes the hazards and risks from the use of electricity, explaining with the help of case studies and accident statistics the types of accidents that occur and how they can be prevented by the use of safe installations, equipment and working practices. It describes the British legislation on the safety of electrical systems and electrotechnical machinery control systems, much of which stems from European Directives and which will therefore be affected by the UK’s decision to leave the EU (Brexit), and the main standards and guidance that can be used to secure compliance with the law. There are detailed descriptions covering the risks and preventive measures associated with electrical installations, construction sites, work near underground cables and overhead power lines, electrical equipment and installations in explosive atmospheres, electrical testing and electrotechnical control systems. Duty holders’ responsibilities for designing, installing, and maintaining safe systems are explained, as well as their responsibilities for employing competent staff. The fifth edition has been substantially updated to take account of considerable changes to the law, standards and guidance; it has been expanded to include: a new chapter on the Corporate Manslaughter and Corporate Homicide Act; a new chapter describing landlords’ legal responsibilities for electrical safety in private rented properties and social housing; a new chapter on the Electricity Safety Quality and Continuity Regulations; new information on offences, penalties, sentencing guidelines, and relevant case law; a description of the main requirements of BS 7671:2008 and other principal standards, many of which have been amended in recent years; new cases studies to illustrate the hazards and risks; information on changes to GB’s health and safety system.

Download or read book A Novel Intrabody Communication Transceiver for Biomedical Applications written by Mir Hojjat Seyedi and published by Springer. This book was released on 2016-11-08 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph explores Intrabody communication (IBC) as a novel non-RF wireless data communication technique using the human body itself as the communication channel or transmission medium. In particular, the book investigates Intrabody Communication considering limb joint effects within the transmission frequency range 0.3-200 MHz. Based on in-vivo experiments which determine the effects of size, situations, and locations of joints on the IBC, the book proposes a new IBC circuit model explaining elbow joint effects. This model not only takes the limb joint effects of the body into account but also considers the influence of measurement equipment in higher frequency band thus predicting signal attenuation behavior over wider frequency ranges. Finally, this work proposes transmitter and receiver architectures for intrabody communication. A carrier-free scheme based on impulse radio for the IBC is implemented on a FPGA.
