ATF Classification

High explosives: detonate rapidly, creating a supersonic shock wave (e.g., TNT)
Low explosives: deflagrate slowly, creating a subsonic shock wave (e.g., black powder)
Blasting Agents: a chemical mixture of fuel and oxidizer, not classified as an explosive (e.g., ammonium nitrate/fuel oil)
