This book covers all the key elements of health and safety as it stands as a discipline at the beginning of 2017. It provides a quick reference, focussing on hazards in the workplace and practical controls of risk. The aim has been to present the health and safety processes so that, if these are understood, appropriate solutions to a very large range of health and safety issues can be developed. Throughout this book reference has been made to many different documents, most of which are available free from the UK Health and Safety Executive’s website. This book has been arranged, to a large extent, around the syllabus of the NEBOSH National General Certificate (NGC). It is hoped that the book will be a useful aid to people studying for the certificate, acting as a supplement to training material from course providers or to assist in self-study.
