Fire departments have used our binary flashbangs with much success as "distractionary devices”. The most common model is the M-250 Blast Simulator. These units are "two component" which means those two powders are mixed and added to the casing which has a fuse already inserted in it. "Burn to Learn" are becoming a very popular method of Cadet training (when a condemned house is allowed to be burnt by the local department for training purposes) The house is cleared of gas lines, aerosol cans, gas cans, and other flammable/explosive dangers. The first time, however, a firefighter enters a burning house/garage, they may encounter a large number of explosions. This can be a traumatic and disorienting experience for the inexperienced firefighter. Without the training and knowledge of how to react to explosions, it puts the firefighter/others at possible risk. The M-250 Blast Simulator is placed in strategic locations which will be exposed to fire. It offers a loud report and flash without the danger of shrapnel. These distractionary devices are indescribably important to basic education, and since they are binary, they are not subject to Federal storage requirements as are other explosives.
