High explosives are divided into three main categories, Primary (or Initiating) High Explosives, Secondary High Explosives, Boosters and Secondary High Explosives, Main Charge.
As with many of the terms associated with explosions, there is also other terms that describe combustion explosions, “Deflagration Explosion”.
What are the 3 categories of high explosives?
High explosives are divided into three main categories, Primary (or Initiating) High Explosives, Secondary High Explosives, Boosters and Secondary High Explosives, Main Charge. As with many of the terms associated with explosions, there is also other terms that describe combustion explosions, “Deflagration Explosion”.
What was the biggest explosion ever?
But it still pales in comparison to the largest man-made explosion ever on Earth – the Soviet Union’s Tsar Bomba – King of Bombs – detonated in 1961 in the height of the nuclear arms race. That hydrogen bomb unleashed a staggering power of 50,000 kilotons, or 50 megatons.
Is TNT the most powerful explosive?
One of the most popular explosive compounds is TNT (trinitrotoluene). The energy released in an explosion of 1 gram of TNT is approximately 4000 Joules. It is common to measure the power of an explosion by asking how much TNT would be needed to produce an explosion as powerful.
Is Tannerite a high explosive?
Tannerite is a binary high explosive, the best-selling brand of exploding rifle target in America. As the name “binary explosive” suggests, exploding target kits consist of two components: ammonium nitrate and aluminum powder. Unmixed, both are inert and cannot explode.
What are the three types of explosives?
There are three fundamental types: mechanical, nuclear, and chemical. A mechanical explosive is one that depends on a physical reaction, such as overloading a container with compressed air.
What is the most powerful explosive material?
Five of the most explosive non-nuclear chemicals ever made
- TNT. One of the most commonly known explosive chemicals is trinitrotoluene, or TNT, which has featured extensively in video games and films.
- TATP.
- RDX.
- PETN.
- Aziroazide azide.
What are Class A and Class B explosives?
Class C Explosives – a term formerly used by the U.S. Department of Transportation to describe explosives that contain Class A or Class B explosives, or both as components but in restricted quantities.
What are primary high explosives?
Primary high explosives are extremely sensitive to mechanical shock, friction, and heat, to which they will respond by burning rapidly or detonating. Secondary high explosives, also called base explosives, are relatively insensitive to shock, friction, and heat.
What is a Class 1 explosive?
CLASS 1 – EXPLOSIVES. Explosives are materials or items which have the ability to rapidly conflagrate or detonate as a consequence of chemical reaction. Sub-Divisions. Division 1.1: Substances and articles which have a mass explosion hazard.
What is an example of a primary explosive?
Primary explosives are used as detonators: that is, to cause the secondary explosives to explode. Mercury fulminate, picric acid, lead azide, nitroglycerine and iodine nitride are examples of primary explosives. TNT, dynamite, hexogen, HMX and Torpex are examples of secondary explosives.
What are examples of high explosives?
Examples include primary explosives such as nitroglycerin that can detonate with little or no stimulus and secondary explosives such as dynamite (trinitrotoluene, TNT) that require a strong shock (from a detonator such as a blasting cap). Low explosives change into gases by burning or combustion.
What is the difference between low and high explosives?
This can happen under higher pressure or temperature, which usually occurs when ignited in a confined space. A low explosive is usually a mixture of a combustible substance and an oxidant that decomposes rapidly (deflagration); however, they burn more slowly than a high explosive, which has an extremely fast burn rate.
Which chemical is explosive?
Chemical explosive reaction. A chemical explosive is a compound or mixture which, upon the application of heat or shock, decomposes or rearranges with extreme rapidity, yielding much gas and heat.
What are the 9 classes of dangerous goods?
The 9 Classes of Dangerous Goods
- Class 1 Explosives. Explosives are classified as dangerous goods because they are capable of producing hazardous amounts of heat, light, sound, gas, or smoke.
- Class 2 Gases.
- Class 3 Flammable Liquids.
- Class 4 Flammable Solids.
- Class 6 Toxic and Infectious Substances.
- Class 7 Radioactive Material.
- Class 8 Corrosives.
What is a 1.4 explosive?
1.1 — Explosives with a mass explosion hazard. ( nitroglycerin/dynamite, ANFO) 1.2 — Explosives with a blast/projection hazard. 1.3 — Explosives with a minor blast hazard. ( rocket propellant, display fireworks) 1.4 — Explosives with a major fire hazard. ( consumer fireworks, ammunition) 1.5 — Blasting agents.
What is a Class 1 hazardous material?
Division 1.6 Explosives. Consists of extremely insensitive articles which do not have a mass explosive hazard. This division is comprised of articles which contain only extremely insensitive detonating substances and which demonstrate a negligible probability of accidental initiation or propagation.
Is Nitroglycerin a primary explosive?
The main use of nitroglycerin, by tonnage, is in explosives such as dynamite and in propellants. Nitroglycerin is an oily liquid that may explode when subjected to heat, shock, or flame. He named this explosive dynamite and patented it in 1867.
What is a secondary explosive?
Primary explosives detonate by ignition from some source such as flame, spark, impact, or other means that will produce heat of sufficient magnitude. Secondary explosives require a detonator and, in some cases, a supplementary booster. A few explosives can be both primary and secondary…
What is the most explosive gas?
Flame and explosion limits for gases – propane, methane, butane, acetylene and more

|---|---|---|
| Hexane | 1.1 | 7.5 |
| Hydrogen | 4 | 75 |
| Hydrogen sulfide | 4.3 | 46 |
| Isobutane | 1.8 | 9.6 |

Can medical nitroglycerin explode?
In its pure form, nitroglycerin is a contact explosive, with physical shock causing it to explode, and it degrades over time to even more unstable forms. The difference between nitroglycerin as used in dynamite and that used as medicine (non-explosive) is concentration.
What is the most explosive element?
The alkali metals are some of the most highly reactive elements. These elements include lithium, sodium, potassium, rubidium, cesium, and francium.
