The book, produced in A-Z format, incorporates the principal legal, technical and practical terms derived from statutes, regulations, approved codes, case law and other appropriate publications. As such, it will be of particular use to health and safety practitioners, those studying for degrees in occupational health and safety and courses run by NEBOSH, and those engaged in enforcement activities, such as Health and Safety Executive inspectors, environmental health officers and fire protection officers. The key terms referenced and explained include: accident statistics; absolute duties; distance guard; noise-induced hearing loss; oxidising classifications; relevant statutory provisions.
