Process for Producing Non-Detonable Canine Training Aids for Peroxide-Based Homemade Explosives

Reference#: P03404


Canines have a keen since of smell, their noses containing about 20-40 times more odor receptor than humans. Dogs can smell every component that makes up a smell separately and smell odors with fewer molecules in the air. Every dog is trained to search for specific scents. Whether it is a Beagle used in airports to find illegally imported meat, fruit, and vegetables being brought over by passengers or Shepherds used to find roadside bombs overseas. Dogs are an integral aspect of life today.

Currently bomb sniffing training aids that have relatively similar compositions either do not exude vapor at an appropriate rate, or contain off-odors because of the fabrication process and the materials used therein, such as processing solvents.

There is a need for training aid material that can be used to train explosives detection dogs on the odors of a class of peroxide-based materials referred to as homemade explosives (HMEs). The training aids need to exude the same odor as bulk quantities of the real explosives at similar rates of vapor production for at least two hours after opening the training aid package but be relatively safe to handle and non-detonable. This allows the possibility of creating a more accurate bomb sniffing dog.

Researchers at Johns Hopkins Applied Physics Laboratory discovered a process for preparing training aids that meet the aforementioned requirements without introducing any off-odors. Blind testing with dogs not previously imprinted showed that these canines successfully located not only the new training aids but also l g of neat TATP that was synthesized by an external organization. Conversely, a group of canines that had trained on l g of neat TATP synthesized by an external organization successfully located both the TATP filters and the new training aids.

The same procedure used to produce TATP training aids can also be used to produce training aids for the HME known as hexamethylene triperoxide diamine (HMTD).
