With the increase in threats of dangerous homemade explosives such as triacetone peroxide (TATP) and hexamethylene triperoxide diamine (HMTD) that were used in events such as the terrorist bombings in Paris and Brussels, the detection capabilities of man’s best friend in helping to find these threats is steadily rising. Those who rely on canines for explosive detection have to train them with the very explosives that they are looking to detect. In the case of TATP and HMTD this is a very dangerous, and up until this point, almost impractical task. TATP and HMTD are very unstable compounds that can be set off by heat, friction or shock. This makes these homemade explosives dangerous to store and use even in the controlled act of training a dog for detection. The Dog Training Aid (DTA) Microsphere Heater aims to solve the safety and storage concerns of TATP, HMTD and other dangerous explosives while allowing the dog trainer to do their job. The DTA Microsphere Heater utilizes explosives encapsulated into microspheres which render the explosives inert and safe for storage and transport. The DTA Microsphere Heater takes these microspheres and heats them to release the explosives in small, safe and controlled doses onto a collection media that can then be used as a scent aid in dog training. Another benefit of the microspheres is that they also serve to drastically increase the storage life of the explosives from as little as a few hours to well over a year or more.
