A highly detailed, seventeen-page manual for the construction, use, and detonation of several varieties of charges and explosives was recently posted to a password-protected al-Qaeda-affiliated forum. The author provides a brief history of explosive compounds, definitions of terms used in describing their properties, both physical and in methods of use, and a list of substances and locations where the specific materials may be procured. Some ingredients, such as nitric acid, the author indicates are difficult to obtain, ?especially in Palestine,? and offers alternatives and methods of composing the substance. Further, the author suggests: ?when buying large quantities of materials one should take care to use a good cover story, a disguise and false names.?
The manual includes the following explosives: nitrocellulose (guncotton), dynamite, nitroglycol, nitromethanol, nitroglycerin, explosive oils, hexamine peroxide, mercury fulminate, and acetone peroxide. Acetone peroxide, in particular, is focused upon by the author as being ?sensitive and it has killed its makers many times, and that is why we ask anyone who wishes to prepare it to have an expert near him or to follow what is written to the letter.? For each explosive, the author provides ?general rules? and safety precautions, in addition to the step-by-step procedure for their composition.
