In this specialized guide to crisis preparedness, Detlev Hoppenrath addresses how to prepare for and survive attacks using biological or chemical weapons. The book provides precise and comprehensive answers with a clear practical focus on important questions: How do I use a gas mask? What should I do in case of contamination? What about food and water? What effects do different chemical agents have, and how can one protect against them? It is assumed, whenever possible, that specialized equipment is not available and that improvisation with simple means is necessary - highly engaging and very relevant.
