Highly exothermic materials

I wonder what caused someone to do this search:

The Department of Interior did a search at 2300 on a Friday night for “tannerite fire danger”. Tannerite, as most of you know, is a binary explosive used for reactive targets. It is frequently assumed that Boomershoot uses Tannerite. This is not true. We use Boomerite.

Nearly every year we have one or more fires associated with Boomershoot we have to put out. Most of the time it is because we are doing fireball targets. Sometimes it has been because a tracer caused a fire. But sometimes it was because our reactive target either caught fire instead of detonating after being shot or because the explosives spontaneously combusted. One of the ingredients in Boomerite is potassium chlorate. Potassium chlorate is one of the main ingredients in matches. It is believed it is the potassium chlorate that causes Boomerite to spontaneously combust. Tannerite (the last time I checked) does not use potassium chlorate although it does share ammonium nitrate with Boomerite. I suspect Tannerite is less likely to cause a fire than Boomerite but any time you are working with highly exothermic materials the risk of a fire or explosion is present.

If you use highly exothermic materials in association with your gun fun please be careful with it. Be prepared to put out a fire. If you spill some of the materials then dispose of it by soaking the area in water or dispersing and burying the chemicals.

We don’t want the Department of Interior or anyone else banning the use of Tannerite on their land.
