What is considered an explosive?
"Explosive." Explosive - any chemical compound, mixture, or device, the primary or common purpose of which is to function by explosion, i.e., with substantially instantaneous release of gas and heat, unless such compound, mixture, or device is otherwise specifically classified by the U.S. Department of Transportation; ...
What is an explosive and how does it work?
A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases.
What are explosives in chemistry?
“An explosive is any chemical compound or mechanical mixture that, when subjected to heat, impact, friction, detonation, or other suitable initiation, undergoes rapid chemical change, evolving large volumes of highly heated gases—typically nitrogen or CO2—that exert pressure on the surrounding medium.
What is an explosive hazard?
The OSHA Laboratory Standard defines an explosive as a chemical that causes a sudden, almost instantaneous release of pressure, gas, and heat when subjected to sudden shock, pressure, or high temperature. Under the Department of Transportation (DOT) hazard class system, explosives are listed as hazard class 1.
Why are cherry bombs illegal?
Cherry Bombs, Silver Salutes, and M-80's have been banned by Federal Law since 1966 because of the large amounts of explosive composition they contain. If you find any of these items, DO NOT touch them.
What are 1.1 explosives?
Division 1.1 consists of explosives that have a mass explosion hazard. Examples are black powder, nitroglycerine (desensitized), dynamite, most types of torpedoes, and mercury fulminate. Division 1.2 consists of explosives that have a projection hazard but not a mass explosion hazard.
Why do some things explode?
The generation of heat in large quantities accompanies most explosive chemical reactions. ... It is the rapid liberation of heat that causes the gaseous products of most explosive reactions to expand and generate high pressures. This rapid generation of high pressures of the released gas constitutes the explosion.
Why do explosions make noise?
The shock wave and the gas bubble each contain approximately half of the energy produced by the explosion. After the gas bubble is formed, it expands until the pressure inside the bubble is lower than the surrounding pressure. At that point the bubble begins to collapse, causing the pressure inside to increase.
What 3 things do all explosions need?
They require an electrical spark, fuse, intense heat, or sharp blow to initiate their explosion. Secondary explosives are relatively insensitive to heat, shock, or friction and will normally burn rather than detonate if ignited in small quantities in the open air.
What explosion means?
noun. an act or instance of exploding; a violent expansion or bursting with noise, as of gunpowder or a boiler (opposed to implosion). the noise itself: The loud explosion woke them. a violent outburst, as of laughter or anger. a sudden, rapid, or great increase: a population explosion.
What does TNT stand for?
trinitrotoluene (TNT), a pale yellow, solid organic nitrogen compound used chiefly as an explosive, prepared by stepwise nitration of toluene.
What are examples of explosive substances?
TNT and dynamite are known examples of explosive substances. Pyrotechnic substances: a substance (or a mixture of substances) designed to produce an effect by heat, light, sound, gas or smoke (or a combination of them) as a result of non-detonative self-sustaining exothermic chemical reactions.
What is the best description of an explosive?
An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
Is combustible the same as explosive?
A combustible material is something that can combust (burn) in air. ... Finely divided wood dust can undergo explosive combustion and produce a blast wave. A piece of paper (made from wood) catches on fire quite easily.
What is a high explosive made of?
High explosives tend to have the oxygen, carbon and hydrogen contained in one organic molecule, and less sensitive explosives like ANFO are combinations of fuel (carbon and hydrogen fuel oil) and ammonium nitrate.
