    I didn't even realise that "low explosives" were a thing; let's talk about deflagration, detonation, and how high explosives can actually be safer. • Thanks to Steve from Live Action FX: liveactionfx.com/

Steve is extremely qualified as an explosives engineer, but thankfully after what he says here, not as a firefighter.

So in a really dumbed down summary; High explosives have a high tolerance to what causes them to explode, while Low explosives have a low tolerance to what causes them to explode.

The catastrophic explosion in Lebanon was caused by the detonation of a huge amount of ammonium nitrate (NH4NO3) which is a typical high explosive - if you try to ignite it probably won't even burn without fuel, but if you detonate it via a shockwave (some people use a high caliber gunshot to create a shockwave, but a detonator is used too) it creates an incredibly strong explosion, very destructive (brisant)

Well, today I learned something again. High explosives really show that in order to create a runaway reaction, you need high pressure, either by containing it, or by its own shockwave. Thank you, Tom!

Not all explosives are fuel oxidiser reactions though he's describing binary explosives (generally a metal oxidiser reaction) although alot of them these days are actually to do with bond strain, high heat of formation etc in a single chemical (RDX, any of the azides, NTI classic examples) it's not just a really mixed low explosive. It's also catagorized by detonation velocity. The channel explosions and fire explains this really well

So what is technically called Low Explosives is what is more commonly just called explosives, like fireworks. It's interesting to think that carrying 50 kilos of C4 plastic explosive is more safe than 50 kilos of fireworks considering one is used by military and law enforcement and another is used by those as young as elementary school age (with proper supervision of course).

Fun fact, most things can be "fuel" for energy expenditure purposes, and foodstuffs tend to have more chemical energy than explosives, they just also usually aren't oxidized. If you make a big cloud of them, a single spark can make a BIG boom

Low explosives is a thermal reaction high explosives is a chemical reaction. Every Irish schoolboy learned this in his science class, even the quantity allowed for transport. Oh yea, the schoolgirls were included!😂

Are you under the impression that low explosives are not chemical reactions?

Před 18 dny
Gavin Edmondstone
Gavin Edmondstone

Nicely done. Now I am getting into finer points. Not all high explosives are molecular explosive, like TNT or PETN, with the fuel and oxidizer all in one molecule. Some are mixtures such as ANFO (ammonium nitrate-fuel oil) - no chemistry happens when these are mixed. Similarly smokeless powder, usually considered a low explosive, is primarily composed of nitrocellulose which does have a fuel and oxidizer in one molecule. The defining difference is the speed of the reaction. High explosives detonate at a supersonic speed while low explosive deflagrates at a subsonic speed.
