This book was first published in 2007. In this revised version we have corrected errors, cleared up ambiguities and added some new material. Two new chapters on fuel and road environments have been added. We have also added to the sections on Euro NCAP, crash recovery system, safe accident sites and in-depth studies. Various safety systems are presented first and then we describe how different fuels affect the work of the emergency services. We later describe the road environment, equipment, organisation of the work on scene, and extrication in accordance with various flowcharts. The book concludes with a section on various measures that ought to be taken after an operation.
