Since tomorrow is Independence Day and many folks will be displaying fireworks, I thought that this would be appropriate. Amateur use of fireworks sends many people to the Emergency Department every year, and if I can reduce the number of calls there my work is well done.
Many of you do not realize that I am a Certified Ammunition Handler, bestowed by the United States Army. I received that certification whilst I was directing the research and development of defensive and less than lethal pyrotechnic devices several years ago. I also understand the chemistry and physics of explosives.
There are two main classes of explosives, low explosives and high explosives. Most fireworks are in the former category, but there are exceptions.
