This book summarises the British legislation covering electrical safety, including those regulations derived from European directives. It also addresses the legislation relating to the supply and use of safety--related electrotechnical control systems, particularly on machinery. As well as describing the legal framework, and the main legal duties and applicable standards, the book describes electrical hazards and how they arise; the types of accidents and dangerous occurrences associated with the use of electricity; the main safety precautions and protection techniques; testing and maintenance of electrical systems; safety during testing work; the safety of electrical installations and equipment used in flammable atmospheres; and the particular risks associated with underground cables and construction activity. The Fourth Edition has been completely rewritten and expanded to include . legislation (such as the Provision and Use of Work Equipment Regulations 1999), standards and guidance material issued or amended since the last edition. . a new chapter on safety related electrotechnical control systems, incorporating commentary on BS EN 954--1 and BS IEC 61508, the main generic standards addressing the safety integrity of such systems. . a new chapter on the competence of practitioners working with electrical systems and safety--related control systems. This book will make a very useful addition to any safety library and will provide a good reference source on electrical safety-- Safety and Health Practitioner, November 2002

Running alongside the mainstream of Western intellectual history there is another current which, in a very real sense, should take pride of place, but which for the last Lithics after the Stone Age : A Handbook of Stone Tools from the Levant free pdf few centuries has occupied a shadowy, inferior position, somewhere underground. Mathematicians solve equations, or try to. But sometimes the solutions are not as interesting as the beautiful symmetric patterns that lead to them. Written in a friendly style for a general audience, Fearless Symmetry is the first popular math book to discuss these elegant and mysterious patterns and the ingenious techniques mathematicians use to uncover them. Hidden symmetries were first discovered nearly two hundred years ago by French mathematician evariste Galois. They have been used extensively in the oldest and largest branch of mathematics--number theory--for such diverse applications as acoustics, radar, and codes and ciphers. They have also been employed in the study of Fibonacci numbers and to attack well-known problems such as Fermat's Last Theorem, Pythagorean Triples, and the ever-elusive Riemann Hypothesis. Mathematicians are still devising techniques for teasing out these mysterious patterns, and their uses are limited only by the imagination. The first popular book to address representation theory and reciprocity laws, Fearless Symmetry focuses on how mathematicians solve equations and prove theorems.
