Introduction to Health and Safety at Work has established itself, in its first eight years, as the foremost text for students taking the NEBOSH National General Certificate. It has become a significant work of reference for managers with health and safety responsibilities and it is therefore a matter of primary importance that it should be kept up-to-date, as far as is possible, with new legislation and recent developments. It has now been endorsed by NEBOSH as a recommended text book for the National General Certificate course.
