Explosives
Explosives (/ɪkˈsploʊsɪvz/) are reactive substances that contain a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure.
Etymology
The term "explosive" was first used in 1620, derived from the French explosif, which in turn was derived from Latin explosus, the past participle of explodere meaning "to drive out or to drive off".
Types of Explosives
There are several types of explosives, which can be categorized based on their sensitivity, velocity, and composition. Some of the most common types include:
- Dynamite: An explosive made from nitroglycerin, sorbents and stabilizers. It was invented by Alfred Nobel in 1867.
- TNT: Trinitrotoluene, or TNT, is a chemical compound used as a reagent in chemical synthesis and in munitions construction.
- C-4: A type of plastic explosive known for its stability and high explosive speed.
- Gunpowder: Also known as black powder, it was the first chemical explosive and the only one known until the mid-19th century.
Uses
Explosives are used in a variety of applications, including:
- Demolition: Explosives are often used to demolish buildings and other structures.
- Mining: In mining, explosives are used to break up and remove rock.
- Military: The military uses explosives in warfare, for example in bombs and grenades.
- Fireworks: Fireworks are a type of low explosive used in celebrations for their visual and auditory effects.
Safety and Regulation
Due to their potential for harm, the manufacture, transportation, storage, sale, and use of explosives are heavily regulated by laws and regulations. In many countries, these activities require licenses and permits, and are overseen by governmental agencies such as the Bureau of Alcohol, Tobacco, Firearms and Explosives in the United States.
