Having more than a dozen years in dealing with explosives safety, I must state that this is by far one of the best books I've read in dealing with Explosives, Propellants & Pyrotechnics. This book not only covers the basics, but actually goes into enough detail to keep even the most knowledgable persons interest. This book is a great text book that even has questions and answers for each chapter. This book is a must if you are new to the field of explosives and would be a great addition to anyones collection.
