I recently received an email from the ATF saying one of their bulletins, Safety and Security Information for Federal Explosives Licensees and Permittees, has been updated. Of particular interest was what they say about binary explosives (such as Tannerite):
ATF would like to remind those who manufacture, distribute, import, use, or store binary explosives of the vital importance of security safeguards for these materials. After a binary explosive is mixed, it is, by definition, an explosive and must be transported, used, and stored as an explosive. Whether the explosive materials are in the process of manufacture, in storage, or in use, we urge everyone to take all necessary measures to safeguard explosive materials and prevent them from falling into the hands of those who may use them in criminal or terrorist acts. We encourage all persons involved with binary explosives to report any suspicious behavior or unusual activity surrounding these materials to ATF and to local law enforcement authorities. Suspicious behavior may include a customer attempting to purchase large quantities of binary explosive materials while knowing little about the product. Unlike regulated explosives materials, ATF does not require persons to report the theft of precursor or binary explosive components. However, we request that everyone voluntarily report any theft or loss of these chemical explosive precursors to the local law enforcement authority and to the USBDC.
Note: A Federal explosives license is required to manufacture (mix) binary explosives for sale, distribution, or your own business use. Also, users of binary explosives must comply with their state and local explosives regulations regarding binary explosives and their use.
Just common sense advice. We can help avoid attempts at oppressive regulation if we watch out for bad guys ourselves.
