Since the author is a retired paramedic as well as longtime SM community member, I can't think of anyone better qualified to write about this topic. Jay first section is titled Basic Principles which includes topics such as what constitutes an emergency, and the legal aspects of an emergency (which although rather rare is a topic worth discussing here). The book's second (and largest section) deals with a wide range of BDSM emergencies, things like allergic reactions, burn care, bleeding, fainting, etc to "personal emergencies," like defusing arguments or emotional upsets, to what to do in case of a power failure or a visit by the authorities. The book also has a list of recommended first aid supplies in the third section. A lot of what Jay discusses in this book might be considered common sense, but in times of "emergencies," some of these common sense ideas can be forgotten. It's great Jay wrote a short book like this that gives some quick answers in the event something goes wrong during SM play.
Jay Wiseman's Dungeon Emergencies and Supplies provides a common-sense approach to dealing with scene-related medical emergencies. The author is a former paramedic and well-known educator within the BDSM community. The book covers a wide range of potential play-related problems from allergic reactions to cardiac arrest. There are also useful guidelines for preparing a first-aid/emergency supply kit, and a list of references providing additonal information on specific emergencies is given. The book, one of a series of "toybag guides", is compact and could easily be added to a pocket of most toybags.
No one likes to think about an SM scene going wrong, but the truth of the matter is that it happens. An important part of responsible SM play is being prepared for emergencies, and I know of no individual more qualified to provide education about such things than Jay Wiseman. Jay has been an SM practitioner for many years and is a veteran EMT. The advice in this book is practical and written in a clear and concise manner. I have given away copies of this book (and other books of Jay's), and will continue to do so. Other books he has authored show how to please a partner sexually, or to do lovely and hot erotic bondage, or to build your own toys, but this book--this book can save a life.
